1. Mold texture

Most of the individual or organizational customers when ordering medical mold processing are often not very knowledgeable about plastic injection molds. Injection molding is an uncommon product. And only those who work in this field are knowledgeable about the construction of a complete set of molds.

Mold construction has been standardized and common globally. Each mold factory is easy to optimize to suit different products. A basic set of molds must have mold plates, a cooling water system or a heating system. Mold, product tying system, positioning, guiding, battery return spring.

2. Plastic mold steel

Customers often pay attention to the price but forget to pay attention to the medical mold containing steel material. The mold steel has a great influence on the forming of the mold. Cheap mold making units often do not explicitly say or do not mention this issue. Using substandard steel to make molds can help reduce costs, but it also means that the quality of the mold will decrease rapidly with the number of pressings.

It is difficult for an untrained person to distinguish what type of mold steel is. So mold testing is also difficult. Some ordinary steel when tempered will also be difficult to distinguish. Therefore, to avoid fraud in this, it is advisable to specify in the contract about the mold steel material.

If you are more careful, ask the mold making unit to provide additional documents about the origin of materials such as purchase invoices. You can also consult a material expert when accepting molds.

3. Perfection

Here you can see if the mold plates comes squarely, are the mold faces flat or rough, are the mold plates too much apart when assembled, and are the components working properly?

Accessories included: a simple set of molds usually does not have many accessories attached. However, these must-have accessories are: Mold hook, Water line screw, medical mold positioning ring, Mold lock clamp... If it is a hot runner mold, it must come with a temperature controller and an electrical cord.

Finishing inside the mold

The water line system must also be up to standard to be able to keep the appropriate mold temperature while the water does not leak out.

Positions comes with guide pins, positioning must match to create continuity when closing the medical mold and opening the mold. During the opening and closing process, it does not make too much noise…
