I. Introduction When we receive a new mold for proofing, we are always eager to get a result earlier and pray for a smooth process to avoid wasting man-hours and causing trouble. But here we must remi

The molding and processing methods of plastic products for household appliances mainly include injection molding, extrusion molding, thermoforming, hollow molding, lamination molding, compression mold

Principle of two-color injection molding The most common form of two-color product molds is that two identical movable molds should correspond to two different fixed mold cavities, in which the cavity

Two-color injection molding means that a part is realized by injection molding of two kinds of plastics. Two-color injection molding in a broad sense includes overmolding, which is realized by two inj

The plastic machine can't open the mold again, there is pressure, there is speed, there is oil to the cylinder, the pressure is 125kg, why is it often unable to open the mold? 1. Whether the skele

1. Two temperature standards that are not conducive to solving shrinking difficulties 1) The temperature of the abrasive tool is too low, which is not conducive to solving the problem of shrinkage The

Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strictly required, and there should be no markings, pores, and whitening. Haze, black spots

1. Injection mold 1. If the mold cavity is not processed well, such as scars, micro-holes, wear, roughness, etc., it will inevitably reflect on the plastic parts, making the plastic parts have poor gl

Proportional control of injection speed has been widely adopted by injection molding machine manufacturers. Although the computer-controlled injection speed segmented control system has long existed,
