Annealing of plastic products Jul 12, 2019
The annealing treatment of plastic products refers to the plasticization unevenness of the plastic in the cylinder or the uneven cooling rate of the product in the cavity, which causes the internal stress of the product to cause deformation, cracking and aging of the product in the future. The annealing treatment is carried out indoors, using a hot liquid medium such as hot water, hot mineral oil,...

What is snake mark and how to solve it? Jul 12, 2019
Snake mark is an indication when injection molding. So what will cause the snake mark? When injecting a plastic part, the Gate is smaller, while the space of the mold cavity is relatively larger. At this time, the temperature of resin is cooling down before it fullly injects into the whole mould cavity frame. Therefore, it will have a flowing marks remaining on the part surface like a snake crawli...

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...
What is 'Catch hook and thin-wall' of plastic mold products? Sep 18, 2019
What is 'Catch hook and thin-wall' of plastic mold products? 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe. Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall...

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. ...

Analysis of the reasons for slow production during injection molding Jul 26, 2019
The reasons for the slow production during injection molding and the solutions are as follows: (1) The plastic temperature and mold temperature are high, resulting in long cooling time. (2) The glue is long. The back pressure should be reduced, the recycled material should be used less to prevent overhead, and the feed section should be cooled sufficiently. (3) The movement of the machine is slow....

Bank Marks in Mirror-polishing Mould Jul 26, 2019
It is not easy to finish a set of high precision mould of mirror polishing. During polishing, the issues of smoothness of the mould may occur. There are some phenomenas such as graining, orange peel, ripples and bank marks on the mould surface. Today, let's talk about bank marks. Usually, there are two main reasons causing bank marks when mirror polishing the moulds. 1. It is due to the uneven met...

What is the difference between TPU extrusion and injection molding? Aug 05, 2019
Extrusion, also known as extrusion molding or extrusion, is also called extrusion in rubber processing. It refers to a processing method in which the material passes through the action between the barrel and the screw of the extruder, is plasticized while being pushed forward by the screw, and continuously passes through the machine head to make various cross-section products or semi-products. Inj...
