Introduction To Plastic Industry Parts Mould Technology And Parts Standard Guide

What is Plastic Injection Molding Technology?

Plastic injection molding technology is an essential step in perfecting the finished plastic product. There are quite a few applications in metal stamping, glass, and other fields. Moreover, it is associated with the specific name of plastic injection molding technology.

The molding technology of the plastic mold maker has many outstanding advantages compared with the traditional injection molding technology. Because it uses a mold accurate to one percent in combination with an intelligent support equipment system, it helps to manufacture high-precision products without further refinement.

Furthermore, with its superiority, it also saves workers time and effort while creating more and better products.

The role of the plastic mold machine

Injection molding technology is indeed a big step forward for Vietnam's machinery industry and the world as a whole.

This technology opens up many open futures to create more and more quality products with diverse designs. You have to learn the process of plastic mold-making technology.

A guide to the most common standards for plastic parts.

wall thickness

The wall thickness of a thermoplastic part depends on several factors. These factors include the type of thermoplastic used, mechanical stress on the part, electrical performance requirements (if any), and more.

The following are general rules of thumb:

The main wall thickness of the part should be uniform

Avoid rapid thickness transitions. Instead, use a gradient thickness transition of 3 to 1.
The gate for injecting the thermoplastic should be in the thicker section

Wall Thickness Considerations

When designing plastic parts, several factors should be considered to determine the wall thickness of the part. These factors include:

Application requirements such as:
Structural strength
fatigue
deflection
electrical load
The formability of parts includes
Part size
Material flows to the narrowest point
Number and location of doors
Design requirements for registration bodies such as UL or RTI

parting line

The design of the part should include consideration of the location of the parting line, also known as the parting line. The design of the part should also have a draft (the angle of the vertical component) and closure.

The location of the parting line should appear on the main feature plane. When a stepped parting line is required, a draft angle of 7° is preferred, with a minimum of 5°.
