The Causes of Color Instability of Injection Molded Parts Jun 10, 2019
Nowadays, the application of plastic casings has become widespread. For example, electrical shells, as well as our commonly used washbasins, are all plastic, but when plastic processing, color instability is a common problem. 1. First of all, the color instability is related to the high and low temperature of the injection molding machine. Therefore, it is necessary to check the priority when proc...

Learn about AS (SAN) Acrylonitrile-styrene Jul 19, 2019
The plastic material is a solid material which is based on a polymer and is added to the additive at a certain temperature and pressure, and is formed by solidification or cross-linking. Let us learn about the material of AS now. AS is a copolymer of acrylonitrile (A) and styrene (S). It has moderate weather resistance, is not affected by high humidity environment, and is resistant to general grea...
Actual Case Analysis of Poor Shrinkage (1) Jul 26, 2019
Today we are going to discuss one case for the sink mark, we will show what we would do when we face the sink mark problem. 1. Basic information: PE, Holder (car parts) shrinks poorly and snakes are bad. 2. Description: The plan to increase the injection pressure has not been solved. In order to make the resin pressure fully function, the gate thickness is increased and the sink mark is improved. ...

Plastic injection product defects discussion Sep 18, 2019
Today we are going to discuss common defects for plastic injection products. 1. Short shot The plastic part is insufficiently filled (or the injection pressure is not enough, the mold nozzle is too small). 2. Ejector Mark The part is poorly released or the ejector pressure is too high. White marks and bumps appear on the surface of the product: 3. Flow marks: The Part is not slippery, ...
