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...
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...

Injection molding and blow molding Sep 18, 2019
Plastic molding is a process in which a synthetic resin is used to make a final plastic product. Processing methods include: compression molding (molding), extrusion (extrusion), injection molding (injection molding), and blow molding (hollow molding). Let's distinguish between the molding process of injection molding and blow molding. (1) Injection molding: Injection molding is a method in which ...

What is venting defective of product? Aug 19, 2019
When the injection machine starts to molding，the hot melt plastic flows in the mold cavity and squeezes the air in the mold cavity. If the air cannot be discharged effectively, it will cause venting, and the result will be that the product is short-shot or affects the quality. Under this situation, We need to check the injection speed, the mold temperature, Or add venting groove.
