Analysis of injection process of PC plastics

PC plastics have excellent properties, high transparency, good impact toughness, creep resistance, wide temperature range. PC plastics have the following process characteristics
The sensitivity of melt viscosity to shear rate is small, but to temperature is large, there is no obvious melting point, the viscosity of melt is high, the resin is easy to hydrolyze at high temperature, and the product is easy to crack. In view of these characteristics, special attention should be paid to differential treatment: to increase […]

The advantages of spray painting on the surface of plastic parts

The surface of the plastic part can be sprayed to ensure the brightness of the product. Because plastic is so hard to embody, plastic parts look darker, and even darker if they are covered in leather. Therefore, in the pursuit of a beautiful surface, Some customers requires to spray a layer of painting on the surface of plastic parts. This will ensure the brightness of the product.
Spraying the surface of plastic parts can reduce the scrap rate of parts. […]

How to deal with the weld lines of injection parts?

What is weld lines
Weld lines are the most common defects in injection molded products. Except for a few injection molded parts with very simple geometry, weld lines occur in most injection molded parts (usually with one line or V-shaped groove), especially in large-scale complex products requiring multi gate mold and inserts.
Weld lines not only affect the appearance quality of plastic parts, but also the mechanical properties of plastic parts, such as impact strength, tensile strength, elongation at break, etc. […]
