According to Luo Baihui, a member of the Shenzhen Mould Technology Society and a member of Die & Mould Network, the current Chinese mold manufacturing companies must focus on improving product quality and lowering manufacturing costs, and realize a strategic shift from a mold country to a mold powerhouse. Luo Baihui analysis pointed out that the mold industry should vigorously develop high value-added products, take the fine, specialized and strong lines, and create new growth points in the Blue Ocean. In the future development, the mold industry must first pay more attention to the strategic adjustment of its product structure, so that high-grade molds with complex structures and high precision can be developed faster. China's mold industry must closely follow the needs of the market to develop. There is no product demand, product replacement, there will be no technical progress in the mold industry, there will be no mold product on the scale, on the grade. For example, more than 90% of parts and components in automobile production must rely on molding. In the Pearl River Delta and the Yangtze River Delta, the output value of the molds for the automotive industry has increased by about 40%. The level of mold technology, to a large extent, determines the product quality, efficiency and new product development capabilities. Has become an important symbol to measure the level of manufacturing of a country's products.
The development of the mold industry must not rely solely on the industry because it involves issues such as national policies, corporate mechanisms and production materials. However, the development of the mold industry in recent years is enough to make people believe that China's mold level will soon be able to reach the level of advanced molds in the world.
Bakelite Injection Molding Machine
Bakelite, also known as bakelite, also known as phenolic molding, is a thermosetting plastic with high impact toughness, stable quality, corrosion resistance, heat resistance and low temperature. Generally speaking, the process of Dewei forging bakelite Injection Molding Machine brand is divided into the following processes. You can have a look together to better understand the knowledge of bakelite injection molding.
1. Bakelite mold heating
Unlike Plastic Mold, bakelite mold can be produced after being put on the machine. It takes a long time to heat up bakelite mold.
2. Temperature rise of bakelite injection molding material
The customized material of bakelite injection molding machine is generally powder. Under the friction formed by the barrel heating device and the screw, the thermosetting plastic in the barrel is melted by heat to achieve the effect of pre-setting plastic material.
3. Injection molding of bakelite products
After the completion of pre-molding, the mold closes, the screw rod starts to inject, and the molten material is pushed by the screw from the barrel nozzle through the main channel, the diversion channel and the gate of the mold into the mold core, and the mold core is fully filled. Because the melted material is cut and heated during injection molding and the mold is at high temperature, the temperature of the melted material rises rapidly into a fast response situation. The injection time of bakelite products is different from that of plastic products, and the injection time of bakelite products is relatively long.
4. Dry and solid under pressure
After injection, it will enter the pressure maintaining state immediately. The effect of pressure maintaining has two aspects: one is shrinkage, and the other is to ensure that the product structure produced by the bakelite injection molding machine manufacturer can be close and firm. After the completion of pressure maintaining, it will be delayed for a period of time, waiting for the material to be completely dry and solid, and then the product will be finalized.
5. Ejection of bakelite products
Open the mold to eject the finished product, clean the mold, and wait for the next the first mock examination product to go out.
