How to judge the quality of extruded plastic molds

Nowadays, the use of extruded plastic molds is also very common. If you do not notice the quality problem when selection, then the later stage will seriously affect the normal use. Today, I will tell you how to judge the quality of plastic molds.

 First, we must look at the thickness of this mold when choosing, although the mold does not need to use too much force, or other harsh environment, but due to the phenomenon of mold and demoulding often encountered,the plastic mold will be prone to problems such as loss and deformation. The basis for solving these problems is to widen the thickness of the mold. Therefore, in the process of selecting the mold, we can analyze the quality of the mold from the thickness.

 Second, To see if the specifications of the extrusion die are standard, the good mold can control the size of the extruded plastic products produced in the error of Tenths of millimeters, and the inferior mold often produces a product error of several millimeters or even A few centimete. 

 Third, look at the material and workmanship of the entire mold, good mold should be very smooth inside and outside, look shiny, and feels slightly moist, the inferior mold may have burrs or pits on the surface, Both comparison can see the difference in quality.
