injection molding is a method of manufacturing industrial products.

Injection molding is a method of manufacturing industrial products. Products usually use rubber injection molding and plastic injection molding. Ներկայումս, injection molding machines continue to develop in the direction of automation, էներգիայի խնայողություն, intelligence, and unmanned. With its excellent energy-saving characteristics, control characteristics, and processing characteristics, the all-electric injection molding machine will quickly occupy the plastic machine market in the next 20 տարիներ.

Automatic injection molding machine

“Ներկայումս, China imports nearly US$2 billion in precision plastic injection molding equipment from developed countries such as Japan, the United States, and Germany each year, and the import volume is increasing year by year, especially precision injection molding machines used to process precision plastic products. Միեւնույն ժամանակ, China It also encourages all plastic injection molding equipment companies to vigorously develop products with high added value, high technology content, and low energy consumption to enhance international competition in the industry.”

Հիմա, the development trend of processing technology is moving in the direction of high and new technology. These technologies include: micro ներարկման համաձուլվածք, high filling compound injection molding, water-assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, և այլն.

Recently, not only my country, but also the X-RITE528 reflection densitometer in the United States, the United Kingdom, Japan, South Korea, եւ այլն, the machinery industry in these countries uses various types of ներարկման ձուլման մեքենաներ to operate the development of the industry. Among them, horizontal injection molding machines and vertical injection molding machines are the most widely used. There are also all-electric injection molding machines, all-electric injection molding machines, energy-saving injection molding machines, rapid prototyping machines, plastic molding machines, high-speed precision molding machines, and large two-platen injection molding machines.

Any changes in size and pattern are accompanied by the adjustment and adaptation of the entire industry. Before the arrival of all-electric injection molding machines, frequency converters and opportunistic technology are necessary transitions for energy saving of injection molding machines, and frequency converters are the transition of servo technology. Ներկայումս, most domestic injection molding machines adopt PLC control system. Այնուամենայնիվ, the PLC control method also has its shortcomings. Օրինակ, its anti-interference, reliability and temperature control accuracy are not ideal in some cases.

The servo drive system not only has unparalleled superiority in terms of control accuracy and system response, but also completes a mechanical soft start, which has a small impact on the power grid. Now that the servo technology is quite mature, with the reduction of equipment costs, the next 20 years will be the era of fully servo-controlled injection molding machines.

Why does the injection material change color during injection?

1. Too high temperature will cause the color of the material to change
2. Toner is not resistant to high temperature will also cause color change
3. The remaining material in the barrel will also cause the color to change
4. Too fast injection speed causes too much shear force to change color
5. Reasonable runner design department will also cause excessive shearing force and cause discoloration
6. Material additives can also cause color changes
7. The screw problem will also change the color of the material with excessive shearing force
