Do You Know The Process of Acrylic Injection Molding?

Acrylic Injection transparent plastic has high light transmittance, and the surface quality of plastic products is strictly required, and there should be no defects such as streaks, pores, whitening, halo, black spots, discoloration, and poor gloss. , Mold, and even product design, we must pay great attention and put forward strict or even special requirements.

Secondly, because most of Injection Moulded For Acrylic transparent plastics have high melting point and poor fluidity, in order to ensure the surface quality of the product, it is often necessary to make fine adjustments in process parameters such as higher temperature, injection pressure, injection speed, etc., so that the Injection Molding can be filled with the mold. , and will not cause internal stress to cause product deformation and cracking.

The material used in Clear Acrylic Injection Molding products is polymethyl methacrylate, referred to as PMMA, alias: acrylic, acrylic, plexiglass. It is a kind of plastic material with high transparency (light transmittance above 92%), not brittle, and often replaced by glass products. Widely used in instrumentation parts, car lights, optical lenses, transparent pipes, light guide equipment. Because the material is easy to color, it can also be injection molded into various colors of colorful and exquisite transparent handicrafts.

However, due to the unique characteristics of acrylic material with high melt viscosity and fast cooling rate, the injection molding product Acrylic Box For Injection Mold is prone to internal stress cracking, thick glue position shrinkage, air bubbles, deep bonding line, deformation, surface finish and transparency. Various bad defects affecting appearance requirements and structure. As a result, the injection molding process is difficult, the cycle is long, and the cost is high, and it is difficult to meet customer requirements.
