In life, how to distinguish the quality of plastic moulds is indeed a difficult point, especially for remote transactions online. The main obstacle is that the mould is not like other products. Other products have samples. Customers can use the samples to identify whether this product is the product they want.

The mold is customized. After the customer determines that the mold is to be opened, the sample or drawing is provided to the supplier, and the supplier processes and produces it. The quality of the mold depends not only on the mold itself, but also on whether the products processed by this mold are qualified. Generally speaking, the evaluation of the performance of plastic mold products mainly has three aspects:

1. Appearance quality, including completeness, color and gloss;

Second, the accuracy between size and relative position, that is, dimensional accuracy and position accuracy;

Third, the mechanical properties, chemical properties, electrical properties, etc. corresponding to the use, that is, functionality. Therefore, if any of the above three aspects of the problem occurs, it will lead to the production and expansion of mold product defects.

The mold itself, the first thing to look at is the material of the mold. Many customers know that the mold material is determined with the manufacturer before the mold is placed. The choice of mold material is actually a choice of steel. The choice of steel is actually the choice of steel hardness and toughness. For the mold, the greater the hardness of the selected steel, the less likely it is to wear during the production process, and the longer the service life. Longer service life also means that the mold can produce more products, which is a savings for plastics manufacturers.

Secondly, it depends on whether the mold is easy to break under normal production and maintenance and often needs to be repaired. Everyone knows that things that are easy to break are definitely bad.

Furthermore, check whether the produced product has burrs, burrs, and whether the surface is smooth. There are flashes, burrs, and it is definitely not good to be non-smooth. The injection molding factory must also arrange for people to dispose of the burrs, which is a waste of time and a waste of manpower and resources.

In addition, see how many moulds can be punched in one minute, that is, how long it takes to mold one mold. This is also the production cost of the injection molder under consideration. If the mold opening speed is faster, the more products are produced in a specific time. Many, can effectively save the production costs of injection moulding manufacturers.
