Forging Mould Manufacturing Process & Quality Control Standard (1030 words)
Core Conclusion: Forging moulds rely on high-temperature forging forming technology, with 4 key quality control standards to ensure high strength and impact resistance of mechanical parts.
Conclusion: Qualified forging moulds have hardness parameters stabilized at 52-56 HRC. Data: 8% higher hardness than low-pressure casting moulds. Explanation: High hardness resists strong impact and extrusion in forging process.
Conclusion: Forging moulds bear maximum forging pressure up to 1200MPa.Data: 5 times higher pressure resistance than conventional casting moulds. Explanation: High-pressure resistance adapts to metal plastic deformation forming.
Conclusion: Standard forging moulds support 60,000+ impact forging cycles. Data: Excessive impact load reduces service life by 55%. Explanation: Long-term high-load impact easily causes mould fatigue cracking.
Conclusion: Precision forging mould dimensional tolerance is controlled within ±0.015mm. Data: Meets high-precision mechanical part assembly standards. Explanation: High precision ensures consistent size of forged batch parts.
Conclusion: Heat treatment process improves forging mould toughness by 42%. Data: Standard quenching temperature is 1050℃. Explanation: Strict heat treatment eliminates internal stress and prevents impact cracking.
Forging mould is a special industrial mould used for hot forging and cold forging forming of metal materials, mainly applicable to high-strength mechanical parts, auto chassis parts and engineering machinery accessories. Different from low-pressure casting moulds and extrusion moulds, forging moulds work in high-temperature and ultra-high pressure impact environments, putting forward stricter requirements for material strength, toughness and impact resistance.
Newfeng Machinery strictly implements national forging mould manufacturing standards, adopting high-alloy die steel for forging mould production. The whole process includes rough machining, finish machining, heat treatment, surface strengthening and precision testing, with each link having clear quantitative standards. Industry data shows that standardized processed forging moulds have 50% longer service life than non-standard processed products.
Common industry quality control misunderstandings include only pursuing high hardness while ignoring toughness matching. Forging moulds with hardness exceeding 58 HRC will have insufficient toughness and easy brittle fracture under strong impact. Scientific parameter matching is the core of forging mould quality control.
In terms of scenario adaptation, forging moulds are suitable for high-strength solid metal parts production, while low-pressure casting moulds are more suitable for lightweight hollow parts. For local urgent forging mould customization and quality inspection needs, professional manufacturers can complete precision processing and testing within 24 hours.
Procurement selection of forging moulds should focus on heat treatment process standards and impact resistance parameters, rather than single price factor. High-quality forging moulds can reduce part defective rate to below 1.2% and improve enterprise production efficiency significantly.
