The injection molding process involves melting the plastic in an extruder, injecting the plastic into the mold with an extrusion screw, and cooling the plastic in the mold. In injection molding, speed and stability are the most crucial elements for success because profit margins typically fall below 10%.
1.Speed:
A processing injection molder can increase throughput by reducing the molding cycle, which is the sum of the molten plastic, injection, cooling, and demolding times. Yields can also be increased by using large molds that can make multiple parts in a single molding cycle. This type of mold is called multi-cavity mold.
2. Stability:
An equally important factor in output. By carefully controlling the plasticizing temperature, the plasticizing pressure during filling, the filling rate and the cooling process, the process stability can be maintained. These four injection molding process parameters interact with each other, for understanding process changes and solve problems is very useful. Although these process parameters apply to almost all injection molding processes
, With different applications, the choice of materials and the different preferences of the injection molding, the process used by each workshop will be different.
3. Filling speed:
When injection molding thin-walled products, the material must be injected into the mold as quickly as possible to prevent freezing of the part mold before it is filled with material. The latest resin materials and plastics machinery technology in this area is almost always aimed at a faster and more convenient filling process. In addition to reducing molding cycles through better mold filling processes, injection molders can also reduce costs by using thin-walled molds or larger, more die cavities.
The thin wall forming process requires the injection molding machine to complete the filling process in less than a second, and the machine itself can support large, multi-cavity molds. Thin-walled and thin-walled containers are generally small, so the mold can produce more than 100 caps at a time.
