Syringe Mould common problems and solutions

Syringe Mould common problems and solutions:
1. The breakage of the syringe mould
Due to improper temperature control, the forging Syringe Mould material itself has cracked. In this case, the only way to change the template is to change the template. Cracks and even broken templates in production are often caused by the selected materials with high heat treatment hardness and excessive stress. Cracking occurs easily during welding. 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 hug around the template.
2. Wear of syringe mould
In particular, thermosetting plastic moulds and aluminum alloy injection moulds are severely worn. Insufficient hardness of the movable parts in the injection mould, 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.
3. Poor heat dissipation of the syringe mould.
The heat dissipation of the long core mould 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, they have higher strength, hardness, fatigue resistance, wear resistance and good heat transfer.
Material requirements for syringe moulds With the development of the plastics industry, the complexity and precision of plastic products are becoming more and more demanding, and higher requirements are placed on syringe mould materials.
