How to deal with scratches on rotational molding molds?
During the use of rotational molding molds, scratches may occur, which not only affects the appearance of the molds but also may impact the quality of the products. The treatment methods for scratches on rotational molding molds can be approached from the following aspects:

Surface grinding
Fine sandpaper polishing: Gently sand the scratched area with fine sandpaper. The finer the sandpaper, the better the polishing effect. During the grinding process, water can be added appropriately to prevent the plastic surface from being burned.
Polishing wheel grinding: Use a cloth polishing wheel with polishing paste to gently rub the scratched area, which can effectively remove the scratches.
2. Use a polishing agent
Specialized polishing agent: Purchase a specialized polishing agent for plastic products and use a mild polishing method for grinding, which can remove obvious scratches.
Scratch cream: After applying the scratch cream, a slight sanding can also effectively remove scratches.
3. Surface coating
Teflon coating: Teflon coating is a non-stick coating that can act as a thermal isolation device, making the product surface smooth and clean. This method is applicable to both iron and aluminum molds, but it should be noted that the coating is prone to peeling off and the product deformation is relatively large.
4. Surface treatment
Etching treatment: Through etching treatment, decorative patterns can be formed on the surface of the mold, concealing the defects produced on the product surface during the forming process and enhancing the aesthetic appearance of the product.
5. Preventive measures
Anti-scratch coating: Applying an anti-scratch coating on the surface of the mold can effectively prevent scratches. Anti-scratch coating is a transparent film that covers the surface of the mold to prevent it from being scratched by external objects.
Proper use and maintenance: Avoid using hard objects to wipe the surface of the mold. Regular maintenance of the mold can prevent surface scratches, fading and aging.
Through the above methods, the problem of scratches on rotational molding molds can be effectively dealt with, maintaining the surface quality and service life of the molds.
