Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression method and die casting method.
Injection molding machine (abbreviated as Injection Machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make various shapes of plastic products from thermoplastics or thermosets. Injection molding is achieved through injection molding machines and molds. Ceramic Substrate Hybrid Integrated Circuit Sheet
1. Rubber injection molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into the model to vulcanize. The advantages of rubber injection molding are: although it is an intermittent operation, the molding cycle is short, the production efficiency is high, the blank preparation process is eliminated, the labor intensity is small, and the product quality is excellent.
2. Plastic injection molding: Plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure and cooled to form various plastic parts. There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastic is polystyrene.Ceramic Substrate Hybrid Integrated Circuit Sheet
3. Molding and injection molding: The resulting shape is often the final product, and no other processing is required before installation or use as the final product. Many details, such as protrusions, ribs, and threads, can be formed in one step of injection molding.
An injection molding machine (injection molding machine) has two basic components: an injection device and a mold clamping device for melting and feeding plastic into the mold. The function of the clamping device is:
1. Make Ceramic Substrate Hybrid Integrated Circuit Sheet the mold close under the condition of withstanding the injection pressure;
2. Take the product out of the injection device to melt the plastic before it is injected into the mold, and then control the pressure and speed to inject the melt into the mold. The injection device used today has two designs: screw preplasticizer or two-stage device, and reciprocating screw. The screw pre-plasticizer uses a pre-plasticizing screw (first stage) and then injects molten plastic into the injection rod (second stage).
The advantages of the screw preplasticizer are constant melt quality, high pressure and high speed, and precise injection volume control (using mechanical thrust devices at both ends of the piston stroke). These advantages are required for transparency, thin-walled products and high production rates. Its disadvantages include uneven residence time (causing material degradation), higher equipment costs and maintenance costs.
The most commonly used reciprocating screw injection device does not require a plunger to melt and inject the plastic.
The types of injection molding machines are: vertical, horizontal, and all-electric, but no matter which type of injection molding machine, its basic functions have two:
(1) Heat the plastic to reach a molten state;
(2) Apply high pressure to the molten plastic to make it eject and fill the mold cavity.
