PCS

PCS (Precision Components Systems) is a manufacturer of mold components and tooling accessories, headquartered in the United States. The company specializes in producing standardized components for injection molds, die casting dies, and industrial tooling. PCS product families include ejector pins (stepped, straight, and hard core), leader pins, bushings, angle pins, support pillars, stop discs, and other mold base components. These components are manufactured from tool steels (e.g., AISI D2, H13, 8620) and are available with surface treatments such as nitriding, black oxide, or through-hardening. Typical hardness specifications range from Rockwell 50 to 62 HRC, depending on the component type. Dimensional tolerances are held to ±0.0005 in or tighter on critical diameters, with length tolerances of +0.062/-0.000 in for ejector pins. PCS components are designed to meet industry-standard dimensions (inch and metric) for compatibility with common mold base systems. 3G Electric supplies over 180 SKUs of PCS mold components, including ejector pins, shoulder bushings, angle pins, support pillars, and stop discs. The inventory covers a range of sizes: nominal diameters from 1/32 in to 5/8 in for pins, outside diameters up to 1.6875 in for stop discs, and overall lengths up to 10 in for angle pins. Each component is specified with material grade, hardness, surface finish, and tolerance data to allow engineers to select the correct part for their mold design. 3G Electric provides technical datasheets and dimensional drawings for each SKU, enabling procurement specialists to verify fit and performance before ordering. The product line supports applications in injection molding, die casting, stamping, and general industrial tooling where precision alignment, ejection, and support are required.

Common Applications

  • Injection molding — PCS stepped ejector pins (e.g., SP3-83) for ejecting parts from core cavities
  • Die casting — PCS hard core pins (e.g., CPH15-3) for forming internal features in aluminum or zinc dies
  • Slide actuation — PCS radius angle pins (e.g., APR33-L10) for guiding core pulls in mold bases
  • Mold support — PCS support pillars (e.g., 1550) to prevent plate deflection in large injection molds
  • Ejector plate alignment — PCS shoulder bushings (e.g., BU-102) for guiding ejector pins in mold bases
  • Wear protection — PCS stop discs (e.g., SD-15) to limit ejector stroke and prevent over-travel damage

Frequently asked questions

Common questions about PCS from 3G Electric.

What materials are PCS ejector pins made from?

PCS ejector pins are typically made from tool steel, such as AISI D2 or H13, depending on the specific product line. General-purpose stepped ejector pins (e.g., SP3-83) use tool steel with a surface hardness of Rockwell 58 to 62 HRC. Hard core pins (e.g., CPH15-3) are through-hardened to a minimum of 50 HRC on both core and surface. The material choice provides wear resistance and dimensional stability under repeated thermal cycling in injection molds.

What tolerances do PCS angle pins like the APR33-L10 hold?

PCS angle pins, such as the APR33-L10, are manufactured with tight dimensional tolerances. The nominal pin diameter is held to +0.000/-0.0005 in, and the press-fit length is controlled to ±0.005 in. The surface is nitrided to a hardness of 65 HRC with a core hardness of 35 HRC, ensuring wear resistance while maintaining toughness. These tolerances allow for precise alignment in mold slide mechanisms.

Are PCS support pillars like the 1550 available with tapped holes?

Yes, PCS support pillars, such as the 1550 model, are supplied with tapped holes. The 1550 has a 3/8-16 threaded hole and includes a 3/8-16 x 1 in socket head cap screw. The pillar is made from Grade 1040 steel with an outside diameter tolerance of +0.000/-0.015 in and a length tolerance of +0.002/+0.001 in. This design allows for secure mounting in mold bases to prevent deflection under clamping force.

What surface finishes are available on PCS stop discs?

PCS stop discs, such as the SD-15, are available with a black oxide finish. The disc is made from Grade 8620 steel, hardened to Rockwell 58 to 62 HRC. The black oxide coating provides corrosion resistance and reduces glare during inspection. The outside diameter tolerance is ±0.001 in, and thickness is held to ±0.005 in, ensuring consistent stack-up in mold assemblies.

How does 3G Electric ensure PCS components meet specification?

3G Electric provides detailed technical specifications for each PCS SKU, including material grade, hardness, surface treatment, and dimensional tolerances. Datasheets and dimensional drawings are available upon request. All components are sourced directly from PCS or authorized distributors, ensuring traceability and adherence to original manufacturing standards. Buyers can compare specs across multiple SKUs to select the correct part for their application.
