Cosmetic Bottle Cap Mould Unscrewing Plastic Molding

The product is Cosmetic Bottle Cap Mould Unscrewing Plastic Molding and use the moulding material is PP. PP has a relatively high shrinkage rate, which can lead to dimensional inaccuracies. Ensuring precise control over the shrinkage is critical to achieving the correct cap dimensions. Cosmetic bottle caps require tight tolerances to ensure proper fit and function with the bottle. Achieving these tolerances consistently can be challenging due to PP's shrinkage and warpage.

In the mold processing process, the mold insert steel uses H13 steel with a hardness of HRC48 - 52, and the mold life of the steel can reach 500,000shots or more. Cosmetic products demand high-quality finishes, so minimizing these defects is essential. The surface finish of the cavity is texture, Our texture is mature and high-quality, and the appearance of the texture is very uniform. The gate way we choose edge gate. Proper gate placement is crucial to ensure uniform material flow and minimize defects. Inadequate gating can lead to uneven filling, weld lines, and visible marks on the caps. Of course, we also have rich production experience in various injection mold types, including caps injection mould, Multi-Material Mould and Pipe Fittings Plastic Mould.
