The most worrying thing about plastic molds is how to distinguish them? This is indeed a difficult point, especially when buying long-distance online. The biggest discouragement is that the mold is not like other products. Other products have samples. Customers can determine whether this product is the product they want through the samples.
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 the product. 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, there are three aspects of the comments on the function of plastic mold products:
1. Appearance quality, including integrity, color and gloss;
Second, the accuracy between scale and relative bearing, that is, scale accuracy and bearing accuracy;
Third, the mechanical function, chemical function, electrical function, etc. corresponding to the use, that is, functionality. Therefore, if a problem occurs in any of the above three aspects, it will lead to the occurrence 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 materials must be determined with the manufacturer before the mold is placed. The selection of mold materials is actually a choice of steel. The selection of steel is actually the selection of steel hardness and toughness. As for the mold, the greater the hardness of the selected steel, the less likely it is to wear during production, and the longer the service life. The longer the service life, it means that the mold can produce more products, which is a savings for the plastic parts manufacturer.
Secondly, it depends on whether the mold is simple and bad under normal production and maintenance and often needs to be repaired. We all know that simple bad things must be bad.
Furthermore, it can be seen whether the output product has burrs, burrs, and whether the appearance is lubricated. There are burrs, burrs, and non-lubrication must not be good. The injection molding factory must also arrange for people to remove the burrs, which is a waste of time and a waste of manpower and resources.
In addition, to see how many molds 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 products produced in a specific time will be The more, it can effectively save the production cost of injection molding manufacturers.
When mold buyers choose mold manufacturers, in addition to considering whether the manufacturers are professional enough, they also have to choose the molds based on the actual situation of the buyers.
