The use of extrusion dies is also very common. If you do not notice the quality of the extrusion when you use it, it will seriously affect the normal use of the extrusion dies. In order to make the molds use well, the following judgments are provided. The specific way of good or bad mold quality.
First, look at the thickness of this mold. Although the mold does not need to be used too much or other harsh environments, but because of many mold release, the mold is very easy to wear, deform, and destroy, and the fundamental way to solve this problem is to add The thickness of the thick mold, so the thickness can clearly distinguish the grade of the mold.
Second, look at whether the specifications of the extrusion die are standard. A good mold can control the size of the extruded plastic product produced by an error of a few millimeters, and the inferior mold often produces a product error of several millimeters or even It is a few centimeters.
Third, look at the material and workmanship of the entire mold. A good mold should be very smooth on both sides. It looks shiny and has a delicate hand. The inferior mold may have burrs or pits on the surface. A ratio of two is a stand-off.
