How to determine the feeding way of the rubber inlet of the plastic mold

The injection way of plastic injection mold mainly includes point injection, diving injection, needle valve injection and direct injection. A reliable manufacturer will be based on the cost of plastic mold. The mold cost will vary greatly with different rubber inlet. The cost of hot runner rubber inlet and spot rubber inlet is higher than that of ordinary diving and direct rubber inlet. We should ensure the quality of plastic mold and the requirements of plastic products, at the same time, choose the appropriate way of feeding. Each way of injection has its own advantages and disadvantages, so when we design the plastic mold, what should we choose the way of injection?

1. Customer requirements

Many customers have very clear requirements for the location and mode of the rubber inlet. When determining the rubber inlet mode, priority should be given to the requirements of customers. If necessary, sufficient reasons must be provided.

2. Appearance and assembly requirements of plastic products

There are many plastic products with strict appearance requirements. For example, some digital electronic plastic parts cannot have any defects on the surface of the product. We must consider whether it will affect the appearance and assembly when selecting the glue feeding method and position.

3. Position of rubber inlet

The position of the rubber inlet is related to the way of feeding. For example, when feeding rubber on the product surface, we usually choose the way of easy breaking and stable feeding.

4. Cost of plastic mold

The mold cost will vary greatly with different rubber inlet. The cost of hot runner rubber inlet and spot rubber inlet is higher than that of ordinary diving and direct rubber inlet. We should ensure the quality of plastic mold and the requirements of plastic products, and at the same time, choose the appropriate way of feeding glue.
