Reduce Your Costs with Long-Life Molds
- Lowers Per-part Cost With Extended Mold Life
- Minimizes Downtime, Maximizes Equipment Utilization
- Ensures Consistent Product Quality Reliably
- Reduces Waste, Advances Sustainable Manufacturing
Why Are Long-life Molds So Important?
Are you frequently troubled by these problems?
Unexpected downtime in production, frequent mold repairs and maintenance, product burrs/dimensional instability due to mold wear, and project profits eroded by premature mold scrapping.Choosing long-life molds can reduce these problems by 95%.
Reduce The Total Cost Of Ownership (TCO)
Total Cost of Molds = Procurement Cost + Maintenance Cost + Downtime Loss Cost + Defective Product Cost.
Industry data shows that downtime due to insufficient mold life accounts for an average of 15% of production time. Based on an 8-hour shift, this translates to an annual cost loss of over $45,000 per machine.
By significantly reducing the latter three costs, lower unit costs and higher return on investment can be achieved.
Stabilize Product Quality At The Source
Mold wear caused the product dimensional tolerance rate to increase by 300% (compared to the initial stage of the product life), resulting in a scrap rate increase from 2% to over 8%, thus reducing yield indicators.
Industry Trends
In high-end fields such as new energy vehicles and medical equipment, mold life has increased from the industry benchmark of 500,000 cycles to 1.5 million+ cycles (ISO 13379-2022 standard), and molds with short lifespans will be eliminated from the market.
Core Technology Solutions For Long-life Molds
Materials Science
- Special hot-work die steels (such as H13 with micro-alloying treatment) are selected, increasing hardness to 52-56 HRC and improving wear resistance by 40% (compared to conventional P20 steel).
- Customized Technology: Gradient heat treatment process (non-uniform quenching) eliminates internal stress peaks and prevents early cracking.
Mold Structure Design
- Stress Optimization Design: Optimizing gate location and runner through CAE simulation (ANSYS) reduces local stress concentration by up to 60%.
- Innovative Insert Structure: Special inserts (such as cavity inserts) are used in critical wear areas, extending mold life by 3 times.
Surface Strengthening Treatments
- PVD Coating Technology: Surface hardness reaches 3500 HV, friction coefficient reduced to 0.15 (compared to 0.35 for conventional molds), reducing sticking and tearing.
- TD Treatment (Carbonitriding): For PC/ABS injection molding, inhibits corrosive degradation, increasing lifespan by 25%.
Precision Manufacturing & Simulation Verification
- Mold Life Verification Standard: Moldflow Analysis to Predict Stress Distribution → Accelerated Fatigue Testing → Mass Production Verification (Customer Field Data).
- Multi-axis CNC, wire EDM, EDM and other equipment ensure microscopic precision
Differences Between Standard Molds and Long-Life Molds
Mold life is a core variable affecting injection molding production costs and quality stability. Standard molds face the risk of precipitous lifespan decline and quality fluctuations during long-term production, while high-life molds, through synergistic optimization of materials, structure, and surface technologies, achieve a 300% increase in lifespan, a 33% reduction in unit cost, and ensure a stable accuracy retention rate of over 92%.

Key Performance Comparison
The fundamental factor determining whether a mold can serve you stably and sustainably over the long term lies in its core intrinsic performance. By fundamentally reshaping key performance indicators, molds can be transformed from consumables into durable production assets.
Wear Resistance
(Based on surface hardness/coating)
- Standard molds (benchmark): 100%
- Our Long-life molds: 250%-400%
Example solution: Through high-end steel + PVD coating, hardness is increased from HRC 50-55 to HRC 70+ or equivalent Vickers hardness.
Corrosion Resistance
(Based on salt spray testing)
- Standard molds (benchmark): 100%
- Our Long-life molds: 300%-500%
Example solution: Using stainless steel or special coatings, salt spray resistance time is increased from tens of hours to hundreds of hours.
Thermal Fatigue Strength
(Resistance to Thermal Alternation)
- Standard molds (benchmark): 100%
- Our Long-life molds: 150%-200%
Example solution: Through optimized heat treatment and material homogenization, crack initiation is significantly delayed.
