    The main reasons for the shrinkage during the injection moulding process

    During the injection moulding process, shrinkage of the product is a common phenomenon. The main reasons for this are: 1. Machine side: (1) The nozzle hole is too large to cause the melt to recirculate and shrink, and when it is too small, the resistance is insufficient and the shrinkage occurs. (2)... read more

    The mould design determines the warpage tendency of the part

    Fundamentally speaking, the mould design determines the warpage tendency of the part. It is very difficult to suppress this tendency by changing the moulding conditions. Finally, the problem must be solved from mould design and improvement. This phenomenon is mainly caused by the following aspects: ... read more

    The causes of bubbles in injection moulding products

    The plasticizing capacity of the injection moulding machine should be appropriate. If the plasticization is too small, it will not be completely mixed and become brittle. When it is too large, it will degrade. The deformation, bending and twisting of injection moulded products are mainly caused by t... read more

    How to improve the manufacturing quality of the mould

    Although mould design is carried out under the expected process conditions when selecting moulding materials and moulding equipment, people's understanding is often imperfect. Therefore, after the mould processing is completed, the mould test must be carried out to see the moulded parts. How is the ... read more
