Custom Punch Pins & Ejector Pins Manufacturer: Precision Fastener Tooling with -0.01mm Tolerance

-

 When manufacturing high-precision fasteners, automotive components, or medical devices, the durability of your cold heading tooling determines your entire production efficiency. A fraction of a millimeter off in a punch pin or ejector pin can cause tool breakage, line downtime, and costly quality claims.

At Jinghong Mold (景渱模具), we solve these technical challenges. Based in Dalang, Dongguan, China, we bring 26 years of specialized expertise in producing high-durability punch pins, ejector pins, and custom mold components engineered to -0.01mm tolerance.

Technical Specifications: Mold Components Comparison

To help engineers and procurement managers select the right tooling material for their specific mechanical environment, we provide full material customization:

Material GradeHardness (HRC)Key Properties & AdvantagesPrimary Applications
ASP60 (Powder Steel)67 – 69Extreme wear resistance, high red hardness, zero burr machiningHigh-cleanliness medical components, high-speed precision stamping
M12 (High-Speed Steel)66 – 67Superior compressive strength, excellent performance under extreme pressureHigh-pressure cold heading, demanding heavy-duty fastener tooling
H55 (Tool Steel)63 – 65Balanced toughness and impact resistance, minimal risk of chippingAutomotive fasteners, high-stress repetitive impact dies
H9 (Standard HSS)60 – 62High toughness, cost-effective, excellent temperature resistance (500–600°C)Standard bolt/screw production, medium-to-large batch manufacturing

Why Leading Manufacturers Partner with Jinghong Mold

  • Micro-Level Precision (-0.01mm Tolerance): Every pin is individually inspected using calibrated micrometers and optical tools to guarantee strict dimensional consistency.

  • Low Minimum Order Quantity (MOQ: 5 Pieces): Whether you need 5 pieces for prototype testing or 200,000 units for mass production, we accept small-batch custom requests.

  • Fast Customization from Drawings: Send us your CAD or PDF drawings (ISO/DIN/JIS/ANSI or non-standard specs), and our technical team will review tolerance feasibility within 24 hours.

  • Direct Factory Ownership: Based in the Dalang industrial hub of Dongguan, we control all core production stages—from material selection and heat treatment to CNC grinding and polishing.

Frequently Asked Questions (FAQ) for Technical Procurement

Q1: What is the typical lead time for custom punch pin orders?

Answer: Standard inventory items ship within 24–48 hours. For custom non-standard punch pins made from technical drawings, production typically takes 3 to 7 business days depending on heat treatment and surface finish requirements.

Q2: Can you manufacture non-standard ejector pins based on custom technical drawings?

Answer: Yes. Non-standard tool manufacturing is our core specialty. We accommodate outer diameters ranging from 2.3mm to 40.3mm, with custom lengths, specialized step configurations, and surface coatings (TIN, TICN, DLC).

Q3: How do you handle international shipping and quality verification?

Answer: We serve over 500 companies domestically and regularly export to over 10 countries, including Russia, Turkey, and Southeast Asia. Full dimension inspection reports and material test certs are available upon request prior to export packaging.

Precision in Every Micron, Excellence Through Every Fire

  Forging the Soul with Craftsmanship, Reaching Horizons with Perseverance — My 26-Year Journey with Jinghong Mold From the ridges of Zigong, Sichuan, to the bustling industrial zones of Dongguan, Guangdong; from a young apprentice earning 300 RMB a month to the helmsman of Jinghong Mold —I have spent twenty-six years deeply rooted in the fastener industry. With nothing but a punch pin and a dream, I carved out my own path. Behind the grease-stained hands and the obsession with technical mastery lies my story: a blend of grit, precision, and responsibility. A Dreamer in a Strange Land In 2003, driven by the innate resilience of a Sichuan native, I dove into the fastener mold industry. At 18, I arrived in Dongguan with a simple bag. My 300 RMB salary was stretched to the limit: 200 RMB for rent and meals, and the remaining 100 RMB was spent either on technical books or sent back home. While the workshop machines roared day and night, I stayed by the lathe, obsessing over the basics ...

H9 Grade Precision Ejector Pins for Screw Header Machines

Why the right ejector pin matters in fastener tooling In screw and fastener cold heading, the ejector pin (also called the KO pin) is one of the hardest-working components in the die set. After every punch cycle, it must push the formed blank out of the die cavity cleanly — without sticking, galling, or wearing prematurely. A pin that is off by even a few microns can cause inconsistent part quality, longer downtime, and higher tool replacement costs. That is why header-machine operators do not just buy "a pin." They buy precision, material grade, and a supplier who can hold tight tolerances batch after batch. What makes Grade H9 ejector pins a reliable choice At Jinghong Mold, our H9 grade precision ejector pins are engineered specifically for screw header machines and cold-heading dies. The H9 material grade is selected for its balanced combination of: High wear resistance under repeated impact and sliding contact Good toughness to resist chipping in high-cycle production...
