What are the characteristics of double color injection molding machine?
Double Color Injection Molding Machines have a similar structure to ordinary injection molding machines. They both have barrels with own passages connected to the nozzles. The molten material is plasticized in the barrel before it is discharged through the nozzle. There are opening and closing valves in the nozzle passageway which control the order and proportion of discharge material. Once the molten material is discharged through the nozzle, it enters the mold cavity. This process allows the user to achieve different mixing effects.
A double color injection molding machine has two independent screw & barrel sets and can perform injection action simultaneously. These types of machines are suitable for multi-material series products. They also have flexibility to perform ejection and rotary table operations. They can deliver more value-added products and reduce production time.
Two-color injection molding uses two different plastic materials in one plastic component. This feature improves the aesthetics and user experience of the finished product. However, the machine requires higher melt temperatures to ensure flow ability. In addition, it requires higher injection pressure than ordinary machines. In addition, two-color injection molding machines have complex mold structures compared to single-color machines.
Two-color injection molding is a complex process that requires higher melting temperatures and mold pressure. It also involves a longer runner. The product is put into the second mold after the first one is filled with the second color. Because of this, it requires two sets of molds.
Ineffective release system can lead to several problems. For example, the mold will not cool sufficiently and the plastics will shrink. It can also result in excessive heat at the gate. In order to avoid these problems, the injection cylinder temperature and the screw speed need to be adjusted accordingly. Also, the valve needs to be installed properly. An ineffective release system can cause excessive pressure loss and lead to irregular operations. It can also result in air pockets.
Ineffective release system is another major cause of sink marks. This happens when molten plastic fails to bond with the plastic mold cavity. In addition, it can occur due to improper clamping force on the mold. The mold can also become worn when it has exceeded its lifespan and will not be able to hold the plastic tightly. Excessive injection pressure may also result in the plastic escaping through the path of least resistance.
Ineffective release system may also result in surface quality issues. The finished part will not be smooth, as it should be. The mold surface is also affected by the surface finish of the mold. The finish affects the customer's satisfaction, so it is important to ensure the quality of the mold surface.
