China Injection Molding

Injection molding is a kind of plastic manufacturing process for the fabrication of plastic products. A lot of plastic products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process needs the use of an injection molding machine, raw plastic material, and a plastic mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final product. In this processing, the temperature controlling is very important, and it will effect the quality of the final plastic product.

Injection molding machine consists of hopper, screw-type plunger, injection ram, and heating units. They are also known as presses, hold their shape mold in which the components. Rated press tonnage, which represents the amount of clamping force can play the machine. This power to keep the mold closed during injection. Tonnage can vary from less than 5 tons to 6000 tons, with less use of higher manufacturing operations in the figure. The total clamping force is forming part of the projected area. This is multiplied by a projected area per square inch from the projected area of 2 to 8 tons of clamping force. As a rule of thumb, 4 or 5 tons/in2, can be used for most products. If the plastic material is very stiff, will need more injection pressure to fill the mold, and thus more clamp tonnage at the mold closed. the necessary strength, can also be used to determine the size of materials and parts, larger parts require higher clamping force.

Injection molding machine classification

  1. Horizontal injection molding machine
  2. Vertical injection molding machine
  3. L-type injection molding machine
  4. Fully hydraulic injection molding machine
  5. Multi color injection molding machine
