Distinguish the quality of plastic molds

In life, how to distinguish the quality of plastic molds is indeed a difficult point, especially in online remote trading. The main obstacle is that the molds are not like other products, and other products have samples, and customers can use samples to identify whether the product is the product they want.

The mold is custom made. After the customer determines that the mold is to be opened, the samples and drawings are provided to the supplier, which is then processed and produced by the supplier. In addition to viewing the mold itself, the quality of the mold depends on whether the product processed by the mold is qualified. In general, there are three main aspects to evaluating the performance of plastic mold products:

1. Appearance quality, including integrity, color and gloss.

2, is the accuracy between size and relative position, that is, dimensional accuracy and positional accuracy.

3. Corresponding mechanical properties, chemical properties, electrical properties, etc., that is, functionality, if there is a problem in any of the above three aspects, it will lead to the generation and expansion of defects in the mold product.

The mold itself, the first thing to look at is the mold material. Many customers know that the choice of mold material before the order is placed with the manufacturer, the choice of mold material is actually a choice of steel. The choice of steel is actually the choice of the hardness and toughness of the steel. For molds, the higher the hardness of the selected steel, the less prone to wear during the production process and the longer the service life. The longer the service life, the more mold the mold can produce, which is a savings for the plastics manufacturer.

Second, it depends on whether the mold is easily broken under normal production and maintenance and often requires repair.

Furthermore, check the products produced for flash, burrs and smooth surfaces. There are raw edges, raw edges, and not smooth. Injection molding manufacturers also need to arrange personnel to deal with raw edges, wasting time and manpower and material resources.

In addition, look at the mold can have several molds per minute, that is, how much time the mold should be formed, which is also the production cost of the injection molding plant. The faster the mold is opened, the more products will be produced in a given time. It can effectively save the production cost of the injection molding plant.
