There are undercuts around products'4 corner,should we make lifter or slider? Jul 08, 2019
As we know, During mold designing, If the product has inner undercut, we usually make lifter, If has outside undercut, we will make slider, But If it has undercut around the 4 corner, and couldn't be forced demoulding, what should we do? As below picture, should we make lifter or slider? 1. Design Analysis If so, first we will think about to make lifter, but after analyze, If make lifter the...

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. ...

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...

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 ...
