What to pay attention to in injection mold

What should I pay attention to in injection molds?

1.The shrinkage coefficient of each material is different, and the plastic mold must have a reasonable shrinkage rate.

2. The plastic mold must have sufficient rigidity, otherwise it will deform when the mold is clamped and held, causing "flash".

3.If the product is ejected while opening the mold, the ejector page of the injection molding machine can be set (but some injection molding machines do not have this function).

4. Choose a reasonable demoulding method, choose a reasonable position and quantity of ejector pins, and ensure that the product is not damaged during the ejection process.

5. The cooling (water passage) in the plastic mold is related to factors such as product size, shape, plastic properties, and pressure holding time.

6. The plastic mold should choose a reasonable exhaust position and its volume control. Otherwise, the plastic injection will be dissatisfied and the product will be "lack of material"

7. The fixing method of the plastic mold and the injection molding machine should be reasonable, reliable and firm to prevent accidents caused by displacement when the mold is closed. And it should be easy to disassemble.

8. The plastic mold follows the movable mold part without the return spring-it moves with the injection molding machine, and the mold thimble plate and the machine thimble rod are connected together (commonly known as the strong top).

9.The injection channel should be selected reasonably, so that the material can reach each place evenly (the flow path is equal), and there should be sufficient storage to ensure that the plastic is supplied with the plastic during the shrinking process.

10.The post-processing of plastic mold materials is not required, because: the plastic is soft, no special requirements such as hardness are required, and the heat treatment process may cause mold deformation.

11. The roughness level in the cavity of the plastic mold must reach the "mirror level", otherwise the product will be difficult to demold, and the product will be damaged due to excessive force when ejecting. The roughness of the positioning pin, mold clamping surface and other parts are all standard regulation.
