Syringe mold fracture: Forged mold material has cracked due to improper temperature control. In this case, only the template is changed. The cracking and even fractured templates in production are often caused by the high heat treatment hardness and excessive stress of the selected materials. Cracking is easy to occur during welding. In severe cases, Cr12 hard material is easy to crack, especially when welding. The template has too much stress and the impact cracks are mostly at the sharp corners of the cavity. If it can be used, it can be perforated and cut in an I-shaped mosaic, and it can also be hugged around the template.
Abrasion of injection molds: Especially thermosetting plastic molds and aluminum alloy injection molds are seriously worn. The hardness of the movable parts in the injection mold is not enough, there is a sharp angle, and the material is not selected properly. For highly corrosive products and plastics with considerable hardness and fillers, the surface of the materials we choose must be resistant to corrosion and have a high surface hardness. Find another injection syringe mold instead.
is very important. The selection of appropriate materials has a big gap between the appearance of the product and the output of the product. If beryllium copper containing beryllium and cobalt is selected, after heat treatment, it has higher strength, hardness, fatigue resistance, wear resistance and good heat transfer.
