1. Polishing Treatment Conclusion: Mirror polishing reaches Ra0.4μm finish, suitable for high-gloss plastic and metal products.
High-standard mirror polishing removes all surface tool marks. It reduces product surface blemishes by 62% and meets high-precision appearance part production requirements.
2. Nitriding Treatment Conclusion: Mold nitriding hardening improves surface hardness by 38% and enhances wear resistance greatly.
Low pressure molds after nitriding treatment form a 0.15mm hard layer. Surface wear loss decreases significantly under long-term high-frequency molding conditions.
3. Anti-corrosion Coating Conclusion: Special coating reduces chemical corrosion damage by 67% for modified plastic molding scenarios.
Coated molds resist acid and alkali additive erosion. It solves the problem of surface oxidation and pitting caused by long-term modified plastic processing.
4. Shot Blasting Treatment Conclusion: Uniform shot blasting forms matte surface, improving product demolding smoothness by 29%.
Matte surface treatment reduces mold and product adhesion force. It effectively avoids pulling damage and burr defects during high-speed demolding.
5. Thermal Refining Conclusion: Surface thermal refining eliminates residual stress, reducing mold surface crack risk by 41%.
Stress removal treatment avoids surface fatigue cracks under alternating cold and hot working conditions, extending mold surface service life significantly.
Surface treatment is a key post-processing process for low pressure molds, which directly affects product appearance quality, mold wear resistance and corrosion resistance. Many ordinary factories omit professional surface treatment to save costs, resulting in rough mold surfaces, easy adhesion and rapid aging. Different low pressure injection mold and low pressure casting mold scenarios require targeted surface treatment processes to match working conditions.
High-gloss product production requires mirror polishing treatment. Electronic accessories, cosmetic shells and other precision appearance parts have extremely high requirements on mold surface finish. Professional mirror polishing processed by Xinfeng Machinery can achieve ultra-smooth surface effect, ensuring no blemish on molded products and reducing post-processing polishing procedures.
For high-frequency continuous production molds, nitriding hardening treatment is essential. The hardened surface layer can resist long-term friction and impact, avoid rapid wear of the mold cavity, and maintain long-term dimensional and appearance stability. It is the standard treatment process for industrial batch production molds.
Modified plastic and special metal molding environments have corrosive characteristics. Anti-corrosion coating treatment can effectively isolate chemical erosion, prevent mold surface pitting and oxidation failure, and reduce frequent mold maintenance and replacement costs. Matte shot blasting treatment is widely used for non-appearance structural parts to improve demolding efficiency.
Residual stress on the mold surface is easily ignored. Long-term cold and hot alternation will expand tiny stress cracks, leading to mold scrapping. Thermal refining stress removal treatment fundamentally eliminates hidden dangers and improves mold comprehensive durability.
