Process steps and details of PP sheet molding
In the process of melting plastic raw materials, a heater is mainly used. Different raw materials are suitable for temperature adjustment. Increasing the temperature will tend to speed up the flow of raw materials, which can increase efficiency but may not guarantee yield. A proper balance must be achieved. . However, the finished product of PP sheet is not a product with high dimensional precision due to the application, so the impact is not big.
When PP sheets are processed, most of them rely on the screw to drive fluidity, so the design of the screw has a great influence. effect.
Among them, the mold is also more complicated, and the shrinkage rate must be considered. In addition to the raw material injected into the runner gate, the injection mold also has a cooling water channel to cool the raw material.
Nanjing Sumino Precision Machinery Co., Ltd. is a high-tech enterprise integrating scientific research, production and sales. It has always adhered to the business philosophy of integrity, equality, and customer benefits. In order to better improve the quality of equipment, it has entered a more professional and standardized Production track. We have established independent research and development technologies for seven categories of equipment including plastic sheet material, casting, bi-stretching, non-woven non-woven meltblown cloth, laminating film composite, recycled granulation environmental protection recycling system and coating machine manufacturing system. The center and production department provide a full set of professional technical solutions to meet the special needs of each customer. Among them, the biaxially oriented film manufacturing system includes: BOPP biaxially oriented film manufacturing system, PVC biaxially oriented shrink film production line, PET biaxially oriented film production line, BOPA biaxially oriented film production line, BOPA biaxially oriented film production line, etc.

Among them, the mold is also more complicated, and the shrinkage rate must be considered. In addition to the raw material injected into the runner gate, the injection mold also has a cooling water channel to cool the raw material.
Any raw material has the problem of shrinkage, and the raw material of PP sheet is no exception. The reason for this is due to the internal stress generated during thermal expansion and contraction and crystal formation. Therefore, the cooling time can be extended in the processing, and the continuous pressure can avoid the shrinkage difference caused by the breakthrough, and the molding quality of the PP sheet can be improved.
