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....

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...
What is warpage on the plastic products? Aug 05, 2019
The products uneven shrinkage caused of some factor, this will creates deformation which we call it warpage. It's a quite normal problem on the plastic products, So how can we solve it? 1. Extending holding pressure time; 2. Design a right gate tipe which will loss minimum pressure. 3. Increasing cooling time; 4. Adding mold cooling tube; 5. Changing product structure, such as adding rib, improvin...

Actual Case Analysis of Poor Shrinkage (2) Aug 09, 2019
Today we are continuing to discuss another case for the sink mark, we will show what we would do when we face the sink mark problem. 1. Basic information: ABS Case shrinkage 2. Description: a. Even if the maximum injection pressure is selected for molding, shrinkage will occur in the place where Rib is behind the molded part. b. As shown in picture, the cross-sectional area of the gate...

Annealing of plastic products Aug 09, 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 minera...
