Always check that the injection moulding machine is set up and running at the temperature specified on the record sheet. this is very important. Because temperature affects the surface finish and yield of the moulded part. All measured values must be recorded and the injection moulding machine checked at the specified time.

Injection moulded parts must be uniformly cooled, that is, different parts of the mould must be cooled at different rates so that the entire product is uniformly cooled. Injection moulded parts must be cooled quickly while ensuring that defects do not occur, such as uneven surfaces, changes in physical properties, and so on.

The cooling rate of each part of the injection moulded part must be equal, but it means that the mould is cooled by a non-uniform method, for example, cold water is input into the inner core portion of the mould, and the outside of the mould is cooled by warm water. This technique should be used when the syringe is moulded to a precision straight product or a large product with a long melt flow.

Always check that the injection moulding machine is set up and running at the temperature specified on the record sheet. this is very important.
