1, Inspection of raw materials

Before production, check the appearance, color, fineness and uniformity of plastic raw materials. If necessary, the properties of plastics should be tested. For plastics with strong hygroscopicity, such as nylon, polycarbonate, ABS, etc., sufficient preheating and drying must be carried out before forming to remove excessive moisture and volatile substances in materials, so as to avoid foaming and grain problems of precision structural parts.

MIM production needs to deal with many details. Only when the details are noticed, the parts produced by the equipment can void various defects. Therefore, operators need to inspect the forming parts produced from time to time to avoid a large number of defective products. To make MIM parts, please choose Shandong No.2 Machinery.
