Conclusion + Data + Explanation: Cooling pipeline dredging and renovation restore 92% of original heat dissipation efficiency. It solves unbalanced cooling after long-term use.
Conclusion + Data + Explanation: Refurbished moulds support 60,000+ stable cycles, reaching 75% performance of new moulds at low cost.
Most aging low-pressure casting mould and low-pressure injection mould have partial wear and precision attenuation rather than overall scrapping. Professional secondary refurbishment can restore mould working performance at low cost, avoiding expensive full replacement. Many enterprises blindly replace old moulds, resulting in huge cost waste. Xinfeng Machinery provides one-stop mould refurbishment and precision recovery services for mass production enterprises.
Surface refurbishment is the basic step of mould recovery. Long-term molten metal scouring and friction cause tiny scratches and wear marks on the cavity surface, affecting product surface quality. Precision polishing and local repair can restore the smoothness of the cavity, consistent with the new mould standard.
Surface performance secondary enhancement ensures durability. Long-term high-temperature operation consumes the nitriding protective layer, leading to reduced hardness and wear resistance. Secondary deep nitriding treatment reforms the protective layer and restores the mould's high-temperature working performance.
Structural calibration and system renovation realize full performance recovery. Wear of guide parts and blockage of cooling pipeline are the main hidden problems of aging moulds. Overall calibration and dredging can eliminate structural deviation and cooling failure, realizing long-term stable reuse of moulds.
