JIS B5012 Standard Die Spring

Product Specification

Feature

1. Full Customization & OEM Support Tailored Engineering: Support for custom dimensions, non-standard load specifications, specialized surface treatments, and private-label branding based on drawings or physical samples. OEM Foundry Experience: Direct factory manufacturing with deep OEM expertise, capable of matching top-tier global brand standards. 2. Abundant Inventory & Instant Dispatch Comprehensive Stocking: Extensive buffer stock maintained across standard ISO, JIS, and American catalog items to ensure high availability for urgent replenishment. Batch Consistency Guarantee: Large inventory lots managed under strict FIFO and batch-tracking controls to ensure seamless part interchangeability over time. 3. Rapid Lead Time & On-Time Delivery Flexible Line Scheduling: Automated coiling and grinding lines paired with flexible scheduling allow for fast turnarounds on both large production runs and small custom batches. Streamlined Export Logistics: Optimized packaging and export handling ensure quick order processing and reliable lead times for international shipments. 4. Premium Grade Materials High-Stress Alloy Steel: Manufactured exclusively from top-grade oil-tempered spring alloy steel (such as 55CrSi / 50CrV4), ensuring superior tensile strength, purity, and resistance to permanent setting. Full Traceability: Mill test certificates (MTC) and complete material heat-number traceability are provided for all raw materials. 5. Superior Mechanical Performance High Energy Absorption in Compact Spaces: The rectangular cross-section stores up to 30%–50% more energy than round wire springs of the same footprint, maximizing space efficiency in complex dies. Precision Ground Parallelism: Ground end faces ensure squareness and perpendicular load distribution, eliminating lateral deflection and protecting mold guide components. 6. Complete Standards & Comprehensive Range Multi-Standard Compliance: Fully aligned with international standards, including ISO 10243, JIS B5012, and American Standard (Inch series). Full Load Spectrum: Covers the entire spectrum from Extra Light Duty to Extra Heavy Duty, allowing 100% direct drop-in replacement for global mold component catalogs. 7. High Temperature & Sag Resistance Thermal Stability: Advanced multi-stage tempering processes minimize thermal relaxation and load loss during continuous high-temperature stamping operations. Resistance to Permanent Set: Maintains nominal free length and load accuracy even under elevated ambient temperatures and long-term pre-load conditions. 8. Durable Color-Coded Powder Coating Standardized Color Identification: Clear, high-visibility electro-powder coating categorized by load class for instant visual identification and error-free installation on the shop floor. Superior Corrosion Resistance: High-adhesion anti-rust coating protects springs against humidity, lubricants, and chemical exposure in harsh industrial environments. 9. Long Fatigue Life & High Durability Controlled Shot Peening: Surface stress is optimized through precision shot peening to introduce compressive stress, drastically boosting fatigue limits and preventing micro-crack propagation. Trapezoidal Profile Geometry: Engineered cross-sectional geometry minimizes internal stress concentration during high-frequency, millions-cycle compression operations.
