- 1. Appearance quality, including integrity, color, gloss;
- 2. Accuracy between size and relative position, that is, dimensional accuracy and position accuracy;
- 3. The mechanical properties, chemical properties, electrical properties, etc. corresponding to the application, ie, functionality. Therefore, if there is a problem due to any of the above three aspects, it will cause the occurrence and expansion of mold product defects.
The mold itself, the first thing to look at is the materials used in the mold. Many customers know that they need to determine the mold materials with the manufacturer before placing the mold. The choice of mold materials 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 harder it is to wear during the production process, and the longer the service life. Longer service life means that the mold can produce more products, which is a saving for plastic parts manufacturers.
Secondly, it depends on whether the mold is easily damaged under normal production and maintenance, and often needs to be repaired. Everyone knows that things that are easy to break are definitely bad.
Furthermore, look at the products produced for burrs, burrs, and smooth surfaces. There are burrs, burrs, and not smooth is definitely not good, injection molding manufacturers have to arrange for people to deal with burrs and burrs, which is a waste of time, waste of manpower and resources.
In addition, look at how many molds can be made in a minute, that is, how long it takes to mold a mold, which is also considered the production cost of the injection molding company. Multiple, can effectively save the production costs of injection molding manufacturers.
