1. Fracture of the Syringe Mould

The main reason is that the forging die material itself has cracked due to improper temperature control. In this case, the only way to change the template is to change the template. In the production of cracks and even broken templates, disposable syringe molds are often caused by excessive heat treatment hardness and excessive stress. Cracking is easy to occur during welding, and in severe cases, especially when welding Cr12 hard materials, it is easy to crack. The template stress is too large and the impact cracks are mostly at the sharp corners of the cavity. If it can still be used, it can be perforated and cut in an I-shaped mosaic, or it can be hugged around the template.

  1. Wear of syringe mold

In particular, thermosetting plastic molds and aluminum alloy injection molds are severely worn. Insufficient hardness of the movable parts in the injection mold, sharp corners, improper material selection, etc. are also causes of wear. For highly corrosive products and plastics with considerable hardness and fillers, the surface of the materials we choose should be corrosion resistant and have high surface hardness.

  1. Poor heat dissipation of the syringe mold

The heat dissipation of the long core mold is very important, and the selection of appropriate materials has a big gap between the appearance of the product and the output of the product. For example, beryllium copper and other materials containing beryllium and cobalt are selected, after heat treatment, Needleless Injection Site have higher strength, hardness, fatigue resistance, wear resistance and good heat transfer.
