The Difference between insert molding and Double Color molding The so-called two-color injection molding refers to injecting two kinds of plastics with different colors into the same mold. It can make the plastic parts with two different colors and make…
Acrylic is also called polymethyl methacrylate (PMMA). Due to the defects , such as low surface hardness, easy scratching, low impact resistance and poor molding fluidity, the modification of PMMA appears alot. Such as copolymerization of methyl methacrylate with styrene…
Addressing Wall Thickness Issues in Injection Molded Parts When it comes to injection molding, the wall thickness is a key factor in determining the performance functionality, manufacturability, and functionality of the finished item. When clients present designs that have an unbalanced…
The plastic mold can be viewed as an exchanger that carries the heat of the hot melt away from the plastic mold by the circulating refrigerant. The cooling system plays an important role More than two-thirds of the thermoplastic injection…
If the plastic parts are unevenly shrinked, the internal stress distribution will be uneven. If the stress exceeds the rigidity of the plastic part, the warpage and deformation of the plastic part will be found, which will affect the dimensional…
Plastic parts are shaped and dimensionally accurate as a function of the temperature of the injection mold during filling, solidification, and production efficiency. Different kinds of plastics have different mold temperatures scope, enabling plastic melt to fill the cavity with…
PET chemical name is polyethylene terephthalate, also known as polyester. At present, GF-PET is the most used among customers, mainly for preform injection. The rheology of PET in molten state is better, and the effect of pressure on viscosity is…
Why venting important？ In a sense, the injection mold is also a displacement device where the hot plastic melt enters the mold cavity while displacing the air in the mold cavity. In fact, the air in the mold is…
Transparent parts have their special characteristics and functionality. The poly-carbonate injection molding will inevitably be used for auto part. When injection molding, we often encounter some thick-walled transparent injection molded parts. For performance reasons, these plastic parts are made of…
