Hardware power tools change development strategy

Hardware power tools change development strategy

Under the pressure of the declining foreign trade market, many manufacturers and distributors of hardware power tools began to switch strategies and began to focus on the development and innovation of the domestic hardware power tools market, and some power tools companies and businesses that are dominant in domestic sales. , It is to play its own advantages, and actively strive to upgrade the file, the development is also very rapid.

Although the domestic market capacity is not as large as the international market, but the demand is still small, most of them are professional electric tools, and the sales price is higher, so the economic benefits are better. As long as the emphasis on product quality, continue to consolidate and develop market share, there is also the same The future can survive and develop in the same way. Luo Baihui, the secretary-general of the International Mould & Hardware and Plastics Industry Suppliers Association, said that as the domestic electric tool market is more discerning about the quality and brand of electric tools, both electric tool distributors and direct users attach great importance to the quality and brand of electric tools. Therefore, the inclination of the market for good quality, good brand electric tools has increased. As long as companies and sellers follow the market market, electric tools are nowhere to go.

Domestic users have higher and higher requirements on the quality of electric tools, and they are particularly concerned about product efficiency, weight, and life. Taking the construction industry as an example, the quality problems of domestically-made electric tools are mainly reflected in the following: electric hammers are prone to heat, the continuous working time is short, the impact of electric hammers is small, and the vibration is large. The operator must use pressure to reach the depth, and the drill bit is easy to wear and tear. Broken and so on.

In order to better develop domestic and foreign markets, more and more manufacturers and sellers of power tools are paying more attention to technological innovation, winning by quality, consolidating and expanding markets with new products. Therefore, the brand awareness and brand effect of the power tool market are even more pronounced. Many power tool distributors with a certain strength and scale have shown great enthusiasm for the distribution of brand power tools.

The power tool market is maturing. After nurturing in recent years, Yongkang electric tool industry has formed many of its own brands and their own brand names, especially a number of well-known power tool brands, such as Boda, Lunda, Sanfeng, Fuqiang, etc., which have been electric in our province and even our country. The tool industry is taking the lead. It can be expected that these brands will grow healthily and rapidly in a disciplined and orderly competitive environment.

As manufacturers continue to focus on corporate brand building, increase investment in science and technology, and develop new products, the power tool industry has achieved a diversified, large-scale, modern, large-scale, and innovative power tool from a single small power tool product. The development direction of the series of products quickly occupied the market commanding heights.

Talking about the Factors of Restricting the Development of China's Hardware Industry

Talking about the Factors of Restricting the Development of China's Hardware Industry The hardware tool market research report shows that in the international hardware supply market, developed countries in Europe and North America have transferred their universal products to developing countries due to the rapid development of production technology and rising labor غير مجاز مي باشدts. They only produce high value-added products, and China has Strong hardware tool market potential, so it is more conducive to the development of a hardware tool export power.

There are still five major defects in the hardware tool industry in China, which hinders the development of the hardware tool industry.

First of all, hardware tools industry is not strong enough to take action. Hardware tool industry, development tool leading enterprises in the foreign market skills, the overall competitiveness of the industry and other advantages are not clear;

Second, skill innovation can be weak. The hardware tool industry identifies only one and three centers of skill (development) in Hangzhou and Jiande.

Third, the market structure is too single. The important business of hardware tools comes from foreign trade orders, and exports are highly dependent on deposits. Under the influence of the economic crisis triggered by the international financial crisis, the export markets of these enterprises have shrunk sharply and constitute a serious threat to life development.

Fourth, the brand establishment is definitely lagging behind. Most of the hardware tools companies rely on OEM consumption, short-term visibility and center competitiveness.

Fifth, there is a shortage of public platforms. Even if there are hardware tool industry associations, industry self-regulation is still more difficult and the focus of the industry associations' development is still difficult.

The hardware tool market survey report pointed out that the overall level of development of an industry ultimately depends on the level of business operations and development speed of the industry. In order to achieve a successful transition from big to strong, China's building materials hardware tools market needs independent self-reliance and self-improvement so as to promote the development of the entire industry.

Musk Announces 2% Increase in Mass Production Price of Tesla Model 3 This Week

[Global Science and Technology Report] According to the BBC website on July 3, Elon Musk, the founder of electric car manufacturer Tesla, announced on Twitter via Twitter that the new Model 3 Will be ready for mass production on Friday, two weeks ahead of schedule. After the announcement, Tesla's stock rose 2%.

Data map

Musk stated that the Model 3 five-seater is Tesla's cheapest car so far, and all the debugging has been completed. "SN1 (serial number 1) is expected to be completed on Friday." Refers to the first car on the production line. Investors were affected by this news. On the 3rd, Tesla’s stock price rose by about 2%. Musk also added that by December, the monthly output will reach 20,000 vehicles.

Model 3 means Tesla is trying to break into the mass market for car users. The base model is priced at ,000 (£27,000), which is almost half of Tesla's current cheapest model. Musk has stated that his goal is to produce about 500,000 cars a year at full capacity.

Earlier this year, Tesla surpassed General Motors and Ford Motor Company to become the most valuable American automobile manufacturer, although in 2016 Tesla produced only 84,000 cars. On the 3rd, Tesla had a market value of billion on Wall Street, while General Motors had billion and Ford had billion. (Internship Compilation: Guo Yihua Reviewer: Li Zongze)

Copper core wire and cable for engineering applications based on current carrying capacity

The copper conductor wire and cable current carrying capacity standard was translated from the section 523 ampacity of the fifth part of the electrical installations of the International Electrotechnical Commission. The standard number is IEC60364-5-523 in 1983. Since the reform and opening up, public utilities and housing construction have developed rapidly, and household electrical equipment and other electrical equipment have increased. However, it cannot be overlooked that in the fires that occur every year, electrical fires also show an upward trend. In a few short years, the proportion of electrical fires has more than doubled, and a considerable part of this has been caused by faults in the insulation of cables and cables, overheated spontaneous combustion, poor contact, single-phase grounding of cables, and short-circuits between phases. Therefore, how to use cables and wires scientifically and reasonably, and accurately select the current carrying capacity of cables and cables, and comply with the norms for management and maintenance, is crucial. As there is no national standard for cable and wire current carrying capacity below 1000V, and the most extensive use of this part of cable and wire, in view of this, the National Standardization Technical Committee for Building Electrical Installations has proposed the preparation of a standard plan to report the national technology. The Bureau of Supervision supervised the adoption of the International Electrotechnical Commission's IEC 60364-5-523 standard as a national standard (China's cable and wire comply with the IEC cable and cable manufacturing standards).

The Standardization Technical Committee of Electrical Installations of Buildings and the International Copper Association are now compliant with the IEC60364-5-523 standard for copper-cored cable and cable current-carrying capacity and provide reference for design, production, construction and installation, quality inspection, operation and management. In 1995, the International Electrotechnical Commission began to revise the ampacity standards for the 1983 edition and has now entered the final approval stage. After a detailed comparison of the two, the following circumstances and changes have been told to the reader:

1. The applicable voltage range is changed to AC 1KV and DC 1.5KV.

2. The current carrying capacity of copper wire 1.0mm2 and aluminum core 1.0mm2, 1.5mm2 was deleted.

3. There is basically no change in the current carrying capacity, and individual variations do not exceed 7%.

4. There is no change in the cable wire type and temperature rise limit.

5. Increase the correction coefficient when the soil thermal resistance is not 2.5Km/W.

6. The textual description of the cable wiring in the table is changed to diagram.

7. Table 52-E4, E5 cancel the non-porous tray's current-carrying capacity data.

8. The following changes have been made to 523.5:

(1). 4-phase and 5-core cables can have larger current-carrying capacity only when the three-phase conductors have load current and balance;

(2) When the three-phase load is unbalanced, the temperature rise caused by the neutral current will be offset by the reduced heating of the line current. In this case, the conductor cross-section should be selected according to the maximum phase current;

(3) When there is a load current at the neutral line, and the phase current does not reduce accordingly, the neutral harmonic current is greater than 10%, and the neutral section should not be smaller than the phase section. See Appendix C for the larger harmonic current correction factor.

9. Increase the number of parallel conductors to achieve some balance of load current distribution.

Customized door industry gave birth to lock customization

Customized door industry gave birth to lock customization Most of our country's lock market is a mechanical mortise lock and a ball lock. The production technology of these two locks is simple. As long as real materials are used, strict control of each production and manufacturing link will not result in quality problems. However, the content of these two kinds of lock technology is relatively low, and upgrading and replacement are more difficult. Therefore, after nearly two decades of development, the domestic lock industry has still not achieved a breakthrough.

However, with the advent of electronic fingerprint locks, the hardware lock industry has changed. With the development of intelligent security technology and the widespread use of chips, electronic fingerprint locks have been rapidly developed. At present, some large brands such as Huitailong, Bailemen, Mingmen, and Sakura have developed smart electronic fingerprint locks. Puxin Hardware is also actively developing digital intelligent lock products, investing a lot of money and manpower, and also set up a production workshop for this purpose. He always said that the smart electronic fingerprint lock may become the last "blue sea" in the lock industry. The market space is still huge, the profit is relatively high, and the profit from after-sales service is also very large, which is worthy of the lock enterprises.

If a company wants to survive, it must walk on two legs in its products. First, it must have high value-added products. It can bring more profits to the company. Second, it needs to have a product with a certain amount. This product only needs Earn a small amount of profits in order to attract consumers' attention and increase brand and business influence. Both are indispensable. For lock companies, ball locks can be used to take the amount, and mortice locks and electronic locks can get more profits.

Locking enterprises and door companies emphasize personalization. It is well known that although the scale development of the lock industry was earlier than that of the door industry, after more than ten years of rapid development in the industry, its industry scale has far exceeded the lock industry. Today, the development of the door industry has become a barometer of the lock industry. Often after the introduction of a new door, lock companies will design and produce matching locks based on that door product. Many European-style locks on the market are produced according to the design concept of high-end European doors.

At present, in the cooperative relationship between door companies and lock companies, the door factory occupies a dominant position. In most cases, the lock companies seek cooperation from the door companies. Few door factories actively cooperate with lock factories. Most owners of lock companies also believe that the locks are accessory products of the door. Only if the door factory is satisfied, the lock products can be sold.

It is understood that in the next five years, the demand for high-end locks in China will exceed 10 billion U.S. dollars. Therefore, lock companies should work hard to develop new products with high technology content and high added value, and increase brand awareness on the basis of vigorously improving product quality. From the current point of view, more and more door companies will choose to cooperate with well-known brand lock companies that have strength and product quality protection. The lock products that high-end wooden doors companies need not only have practicality, but also have certain artistic value. Therefore, lock companies must make efforts in product design, increase research and development efforts, produce personalized products, in order to achieve product differentiation, attracting the attention of the door companies.

Customization of the door industry will result in customized locks. The dimensions of the doors in our buildings are not uniform, making the doors and windows industry still dominated by customization. The customized production of the door industry will result in the customization of the hardware lock industry. Since household products such as doors, windows, furniture, wardrobes, cabinets, etc. can be customized, it is entirely possible that the lock products will be customized. Because the trend of door lock bundled sales is becoming more and more obvious, consumers are more inclined to purchase products that already have locks.

In the future, customization of the lock industry may occur in two situations: one is that locks become a supporting production workshop for door companies; the other is that after a design company receives an order, it arranges door companies and lock companies to follow the order requirements. Production, but the brand owner of the door and lock is the design company. At present, there are already door companies making the first attempt. With the arrival of the peak period of the lock industry, some small micro-lock enterprises will be eliminated. The enterprises that have survived the “labor pains” tenaciously have stronger competitiveness and are more capable of customized production. In the future, high-profile brand companies and enterprises with a certain scale will usher in a new situation of cooperation. Customization of locks will also usher in a new “Blue Ocean”.

Take you up knowledge! Look at the transmission distance of various video interfaces

First, the video signal interface

Monitoring video line types introduction:

SYV and SYWV are divided into two types according to the materials. The physical layer structure of the insulation layer is different. SYV is a solid polyethylene cable. SYWV is a high-physical foam cable, and the physical foam cable has a better transmission performance than polyethylene. (S--coaxial cable Y--polyethylene V--polyvinyl Chloride W--stable polyethylene)

According to the impedance can be divided into SYV50-XXSYV75-XXSYV-100XX ... XX represents the outer diameter of the insulating layer.

1. Composite video signal: General connector is BNC, RCA (Lotus head)

75 stands for resistance, followed by 3 and 5 for its insulating outer diameter (3mm/5mm). Video line:

75-3 transmission distance is about 200 meters; 75-5 transmission distance is about 500 meters; 75-7 transmission speed is about 500--800 meters); 75-9 transmission speed is about 1000---1500 meters; 75-12 transmission The speed is about 2000----3500 meters.

2. S-terminal (or Y/C)

Its scientific name is called "two-component video interface", commonly known as S-terminal, the transmission distance is short 15 meters.

The S-Video connection specification is a specification developed by the Japanese, and S refers to "SEPARATE (separation)", which separates luminance and chrominance output, avoiding the mutual interference of luminance and chrominance when the hybrid video signal is output. The S interface is actually a five-wire interface and is composed of five luminance lines, two video color signals, and a common shield ground line.

Compared with the AV interface, since it is no longer Y/C mixed transmission, it does not need to perform bright color separation and decoding work, and the use of independent transmission channels largely avoids signal crosstalk in the video equipment. The distortion of the image greatly improves the sharpness of the image. However, S-Video still needs to combine the two channels of color difference signals (CrCb) into one channel of color signal C, and then transmit it to the Cb and Cr in the display device for processing. This will still cause some signal loss and distortion. (This distortion is small but can still be found when testing under strict broadcast video equipment). Moreover, since the mixing of CrCb leads to a certain limit on the bandwidth of the chroma signal, S-Video, although it is already relatively good, is far from perfect. Although S-Video is not the best, it is still one of the most popular video interfaces, taking into account current market conditions and other factors such as overall غير مجاز مي باشدt.

3. VGA signal VGA (Video Graphics Array) is a video transmission standard that IBM introduced with the PS/2 machine in 1987. It has the advantages of high resolution, fast display speed, and rich colors. It has been widely used in the color display field. The application, but attenuated, the transmission distance is short and susceptible to interference. Its 3+4/6VGA transmission distance is 15-30M.


4, component video (RGBHV signal)

The color difference interface is based on the S interface, and transmits the blue difference (b) and the red difference (r) in the chroma (C) signal separately, and the resolution thereof can reach 600 lines or more. It usually uses two labels YPbPr and YCbCr. The former represents the progressive color difference output, and the latter represents the interlaced color difference output. Nowadays, many television products rely on the input of color difference to improve the quality of input signals, and through the color-difference interface, multiple levels of signals can be input. From the most basic 480i to 480p of frequency-doubled scanning, even 720p, 1080i, etc. are all It is only through the input of color difference that there is a way to send the signal to the TV. The transmission distance of 75-2RGB is 30-50M, and the transmission distance of 75-3RGB is 50-70M.

5, DVI

DVI-A (Analog, Analog) Interface: This type of interface is actually a variant of the VGA interface. It was previously used on some high-end CRT monitors, but it has basically been eliminated. We often say that "false DVI interface" refers to DVI-A because it still transmits analog signals instead of digital signals that show the advantages of DVI technology.

DVI-D (Digital) Interface: DVI-D is a digital signal interface in the true sense. This is a more advanced place than DVI-A. However, the DVI-D interface also has the disadvantage that users cannot use this interface. Compatible with old-fashioned CRT displays, if you happen to have only a D-Sub interface on the LCD monitor, then the user will only have a dry eye.

DVI-I (Integrated) Interface: This is a hybrid interface that combines DVI-A and DVI-D. It is both compatible with DVI-D and DVI-A (via adapter Connecting to D-Sub) is the best compatible DVI interface. Generally speaking, there is no obvious difference between using single-channel DVI and dual-channel DVI when transmitting video signals below 1600×1200@60Hz. If your monitor can support FullHD (1920×1080) or higher resolution, do not select the single-channel DVI cable. DVI-D can only receive digital signals; DVI-I can simultaneously receive digital signals and analog signals with a short transmission distance of 7-15M.

6, HDMI

Uses the same underlying protocol as the DVI digital signal, so it can also be interchanged with the DVI signal via the adapter, compatible with DVI signals. More powerful than the DVI interface, HDMI allows the transmission of high-fidelity audio signals over the HDMI cable when the communication protocol is established. The seamless connection reduces the connection trouble and also makes HDMI more widely compatible. Supports data transmission rate of 5Gbps and can transmit up to 15 meters.

Compared with DVI, HDMI can transmit digital audio signals and add support for HDCP while providing better DDC optional features. HDMI supports data transmission rate of 5Gbps and can transmit up to 15 meters, enough to handle one 1080p video and one 8-channel audio signal. And because the demand for a 1080p video and an 8-channel audio signal is less than 4 GB/s, HDMI has a large margin. This allows it to use one cable to connect the DVD player, receiver and PRR, respectively. In addition, HDMI supports EDID and DDC2B. Therefore, HDMI-equipped devices have the feature of “plug and play”, and the “negotiation” between the signal source and the display device is automatically performed, and the most suitable video/audio format is automatically selected.

7, SDI

SDI (serial digita l interface) is a "digital component serial interface". Then HD-SDI is a high-definition digital component serial interface. HD-SDI is a real-time, uncompressed, high-definition broadcast-grade camera. It is another technological advancement in the field of security monitoring, providing high-definition image source equipment for the monitoring center.

Second, the control signal

Common control signals, RS232, RS422, RS485, IR, CR-NET (CREATOR control signal)

The RS232 transmission rate is low. In asynchronous transmission, the baud rate is 20 Kbps. The interface uses a signal line and a signal return line to form a common ground transmission mode. This common ground transmission is prone to common mode interference, so the resistance Noise interference is weak. Transmission distance 15 meters to 20 meters. When using a 150pF/m communication cable, the maximum communication distance is 15m; if the capacity per meter of cable is reduced, the communication distance can be increased. Another reason for the short transmission distance is that RS-232 is a single-ended signal transmission, which has common ground noise and cannot suppress common-mode interference. Therefore, it is generally used for communications within 20m.

RS-422 is differential mode transmission, strong anti-interference ability, can transmit 1200 meters, the maximum transmission rate is 10Mb/s. The length of the balanced twisted pair is inversely proportional to the transmission rate. Below 100 kb/s, it is possible to reach the maximum transmission distance. The highest rate transmission can only be achieved at a short distance. The maximum transmission rate that can be obtained on a typical 100-meter long twisted pair is only 1 Mb/s.

The maximum communication distance of RS-485 is about 1219 meters. The maximum data transmission rate is 10Mbps.
