The most worrying thing about plastic injection mould is how to distinguish between good and bad plastic molds? This is indeed a difficulty, especially for long-distance transactions online. The biggest difference is that the mold is not like other products. Other products have samples. Customers can use the samples to determine whether this product is what they want.

The mold is customized. After the customer decides to open the mold, provide samples or drawings to the supplier, and then the supplier processes it. In addition to the mold itself, the quality of the mold also depends on whether the products processed by the mold are qualified. Generally speaking, there are three main aspects about the evaluation of the function of plastic mold products:

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

2. Accuracy between standard and relative bearing, ie standard accuracy and bearing accuracy;

3. The mechanical function, chemical function, electrical function, etc. corresponding to the use, that is, the utility. Therefore, if there is a problem in any of the above three aspects, it will cause the occurrence and expansion of the defects of the mold products.

The mold itself, the first thing to look at is the material used for 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 resistance. Regarding 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. The longer the service life, the more products the mold can produce, which is a saving for plastic parts manufacturers.

Secondly, it depends on whether the mold is simply bad under normal production and maintenance, and often needs to be repaired. Everyone knows that something that is simply bad must be bad.

Furthermore, it can be seen whether the produced product has burrs, burrs and whether the surface is lubricated. There are flashes, burrs, and those that are not lubricated are definitely not good. Injection molding manufacturers also have to organize people to deal with the burrs, which wastes time and resources.

In addition, look at how many molds can be made per minute, that is, how long it takes to mold a mold. This is also the production cost of the injection molding manufacturer. If the mold opening speed is faster, then the product produced within a specific time will be The more, it can effectively save the production cost of injection molding manufacturers.
When choosing a mold manufacturer, a mold buyer, in addition to considering whether the manufacturer satisfies the profession, must also select the mold based on the buyer's own actual situation.
