Common Applications

  • EV charging pins Type 2 (IEC 62196-2), CCS (IEC 62196-3), and NACS (SAE J3400) contacts for charging guns and vehicle inlets
  • Aviation and aerospace connector pins MIL-DTL-38999, GX16, GX20, and custom-spec contacts for harsh-environment electronics
  • Press-fit terminals PCB press-fit pins compliant with IEC 60352-5 for through-hole assembly
  • Electronic contact pins battery contacts, pogo pins, spring-loaded test pins, and signal transmission contacts
  • Locating and dowel pins precision alignment pins for assembly fixtures, jigs, and tooling applications
  • Industrial hardware pins hinge pins, clevis pins, cotter pins, and specialty fastening pins

Manufacturing Support from VOLCRIX

  • Swiss turning production from C11000 copper, C18150 Cr-Zr, brass, stainless steel, beryllium copper, and aluminum alloys
  • Tight tolerance machining ±0.01 mm standard on critical diameters; ±0.005 mm achievable for premium applications
  • Standards compliance pins built to IEC 62196-2, IEC 62196-3, SAE J3400, MIL-DTL-38999, IEC 60352-5, and customer specifications
  • Plating coordination silver, gold, tin, and nickel plating with selective plating options to reduce cost on contact zones
  • Full documentation material certificates, plating thickness reports, CMM dimensional data, and FAI per order

Custom Pins Buyer Checklist

  • Specify the connector standard or application (EV charging, aviation, press-fit, etc.) — this drives material and plating selection
  • Confirm current rating and voltage for electrical pins — higher current requires larger cross-section and thicker plating
  • Provide plating specification silver for best conductivity, tin for cost, gold for premium corrosion resistance
  • Share drawing tolerance class tight tolerances on critical features may require additional inspection steps
  • For series production, confirm volume and packaging — MOQ is flexible for prototypes; production pricing requires annual volume estimates

VOLCRIX Manufacturing Authority — Why It Matters

When you source custom parts from a manufacturer, the question is not just “what can they make” — it is “can they prove it.” VOLCRIX operates under ISO 9001:2015 quality management (the globally recognized QMS standard) and IATF 16949 (the automotive industry’s stricter successor to ISO/TS 16949, required by most OEM and Tier 1 automotive buyers). Every shipment includes material certificates, FAI (First Article Inspection) reports, and dimensional inspection data traceable to calibrated equipment.

Our metrology lab runs Zeiss Coordinate Measuring Machines (CMM) for full 3D dimensional verification, a spectrometer for material composition verification on incoming copper alloys (C11000, C18150, C36000), stainless steel (303, 304, 316), and aluminum grades (6061-T6, 7075-T6), plus surface roughness testers, plating thickness gauges, and hardness testers. Tolerances are held to ±0.01 mm on critical features across Swiss turning, CNC machining, and stamping operations.

Founded in 1991, VOLCRIX has served 500+ customers across automotive, EV charging, aerospace, medical, and industrial electronics. Our factory in Yueqing, Wenzhou — China’s precision manufacturing hub — runs 60+ Japanese Star Swiss turning machines, 40 stamping presses, 20 injection molding machines, and 60 spring machines under one roof.
