Extrusion molds are now widely used. If quality isn't considered during selection, it can seriously affect normal use later. Today, the Suzhou Plastic Mold editor will discuss how to judge the quality of plastic molds.

First, when choosing a mold, you must check its thickness. Although molds don't require excessive force or harsh environments, frequent demolding and ejection can easily cause wear and deformation. Increasing the mold's thickness solves these problems. Therefore, thickness can indicate the quality of a mold.

Second, check if the extrusion mold's specifications are standard. A good mold can control the dimensions of the extruded plastic product to within a few tenths of a millimeter of error, while a poor-quality mold often produces products with errors of several millimeters or even centimeters.

Third, check the material and workmanship of the entire mold. A good mold should be very smooth on both the inside and outside, look glossy, and feel slightly moist and heavy. Inferior molds may have burrs or pits on the surface. The difference between the two is obvious.
