Now, the use of extrusion plastic mold is also very common, if you do not pay attention to the quality problem in the selection, then the later will seriously affect the normal use. Today, Shandong mold will tell you how to judge the quality of plastic mold.
1、 When we choose, we must see the thickness of the mold. Although the mold doesn't need too much force in use, or in other bad environment, because of the phenomenon of inverted mold and demoulding, the plastic mold will be easy to appear loss, deformation and other problems. The basis to solve these problems is to widen the die thickness. Therefore, in the process of selecting the mold, the metal precision mold processing can analyze the quality of the mold from the thickness.
2、 To see whether the specification of the extrusion die is standard, a good die can control the size of the extruded plastic products within a few tenths of a millimeter, while the error of the products produced by poor quality dies can reach several millimeters or even several centimeters.
3、 Look at the material and workmanship of the whole mold. A good mold should be very smooth on both sides. It looks glossy and has a slightly wet hand. A poor mold may have burr or potholes on its surface. The comparison between the two is a high-quality one.
