Although various diamond saw blades produced in China have been widely used in various industries and have achieved remarkable economic benefits, their technical level is still different from that of similar foreign products, mainly in:
1. The entire industry lacks unified management and macro-control. Due to the blind development, the production layout of hardware tools, especially saw blades, has become scattered and scattered everywhere. The quality of products in the tool sales market is unstable, the competition is disorderly, and the price is chaotic.
2. Tool production equipment and overall technical level are relatively backward, and some advanced new technologies and new technologies are applied slowly.
3. The scale of production enterprises is generally small, production is not concentrated, process technology is poor, market competitiveness is lacking, and economic benefits are not high.
4. Insufficient capital investment in tool production, new product development, and process technology research.
5. During the use of the tool, the use rate of the base material is low and the steel is wasted seriously.
Vigorously develop the hardware and tool industry, pay close attention to the development of new products and new processes, accelerate the development of China's hardware and tool industry, and improve economic efficiency and overall technical level. The specific approach is:
1. Investing in the tool industry, paying close attention to the development of new products and the promotion of new technologies and new processes, continuously expanding the application field of diamonds, improving the overall technical level and market competitiveness of the diamond saw blade industry, surviving by variety and quality, and technology Progress and development.
2. In order to meet the needs of the domestic and international tool market, we must accelerate the development of new products, improve product quality, increase varieties, and increase production. In recent years, the demand for diamond saw blades in the processing of machinery, gemstones, medical equipment, wood, fiberglass, stone crafts, ceramics and composite non-metallic hard and brittle materials has increased year by year. At present, these products are still imported domestically, so it is necessary As soon as possible, we have developed a high-quality series of tools to replace imports. At present, the products to be developed include: PDC drill bit for petroleum drilling, diamond grinding block for stone polishing, engineering thin wall drill bit, diamond honing stone, diamond film coating tool, diamond roller, rubber bond diamond plastic tool, PCD diamond tool , diamond needles, nozzles, diamond heat sinks and triodes and other products. In order to ensure the quality of its products, it is necessary to speed up the promotion of new technologies and new processes, such as vacuum welding technology, EDM technology, diamond uniform technology, diamond rhodium plating technology, metallization bonding technology, laser welding technology.
3. Strengthen internal management of the enterprise, continuously improve production processes, reduce production costs, and improve economic efficiency.
4. Take the road of grouping or joint ventures, set up several large enterprise groups, guide the development of the industry, create their own brands, and actively participate in international competition. Relying on scientific and technological progress, increasing investment in science and technology, updating equipment, paying close attention to research and promotion of new technologies, new processes and new products, and improving the technical level of China's hardware industry.
Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.
Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.
