Wall Thickness Design of plastic injection molded products

The wall thickness of a plastic injection molded product greatly influences its quality. If the wall thickness is too small, it will be difficult to meet the requirements for strength and rigidity, and fill the cavity for large and complex products; if the thickness is too large, it not only wastes the raw material, but …

PBT

What is PBT? Polybutylene terephthalate, Abbr. PBT, falls into the polyester series. It is a milky white, translucent or opaque crystalline thermoplastic polyester resin polymerized from 1.4-pbt butylene glycol (1.4-butylene glycol) and purified terephthalic acid (PTA) or dimethyl terephthalate (DMT), before going through a mixing process. It is collectively referred to as thermoplastic polyester, or …

PET

What is PET? Polyethylene terephthalate (PET) is also known as polyester. Currently, GF-PET is the most popular variant among the clients.The rheology of the molten state PET is very good, while pressure has a greater influence on its viscosity than temperature. Therefore, the former is mainly leveraged to change the fluidity of PET melt. 1. …

HDPE

High density polyethylene (HDPE) is a highly crystalline non-polar thermoplastic resin that features a milky white appearance, with a certain degree of translucency in the thin section. It’s tasteless, odorless and non-toxic natural-colored columnar or oblate pellets with excellent hardness, tensile strength, creep / wear resistance and chemical stability. Physical & Chemical Properties The high …

TPE

I. Definition of TPE Thermoplastic Elastomer, AKA TPE, refers to the high molecular material that has the properties of vulcanized rubber (that is, the properties of an elastomer) at normal temperatures, and is able to be plastically deformed at high temperatures. It is able to be made into products with plastic processing machines such as …
