Hand-polishing is a crucial step in the injection mold manufacturing process, aimed at enhancing the surface finish and quality of the mold to ensure the final injection-molded products meet specified appearance and texture requirements.

Here are some key reasons for hand-polishing:

Improved Appearance Quality: Hand-polishing removes microscopic irregularities, defects, and air pockets from the mold surface, resulting in a smoother finish and enhancing the overall appearance of injection-molded products.

Enhanced Surface Smoothness: The surface quality of injection-molded products directly influences their smoothness. Hand-polishing effectively reduces surface defects and blemishes on the mold, creating a smoother surface and improving the perceived smoothness of the final products.

Reduced Friction and Wear: A polished mold surface reduces friction between the mold and plastic material during the injection process, minimizing wear and tear. This contributes to extending the lifespan of the mold and increasing overall production efficiency.

Decreased Demolding Force: A polished mold surface decreases the frictional resistance during the demolding process, helping to reduce demolding forces. This, in turn, prevents product deformation or damage caused by excessive demolding forces.

Meets High Precision Requirements: For high-precision products like precision instrument components, hand-polishing is a critical step to ensure the mold surface is smooth and free of imperfections, contributing to the accuracy of the injection-molded product's dimensions and shape.

Achieves Superior Surface Effects:For products with special requirements, such as mirror finishes or transparent components, hand-polishing can further enhance the glossiness of the mold surface, achieving superior surface effects.

While hand-polishing does add to production costs and time, it is indispensable for manufacturing injection-molded products with stringent appearance quality requirements. We firmly believe that meticulous hand-polishing allows us to deliver products that meet high standards of appearance and quality. We consistently uphold the commitment to providing satisfactory solutions with excellent service and the highest quality standards.
