SILICONE

HTV, HCR, LSR, 2K MOLDING

EXPERTISE & INNOVATION

Approved supplier for the aerospace, medical and pharmaceutical industries

IRP specializes in high volume liquid silicone injection-molded rubber parts, short run - prototype silicone parts, and over-molding of silicone onto plastic. We also process a wide range of compounds such as solid silicone, HCR/HTV/LSR and other elastomer types.

We work with medical device, aerospace and pharma engineers, on their new product development. IRP offers the advantage of a highly experienced team of silicone engineers with years of tooling, part design and production know-how.

Injection Molding

Injection molding

IRP provides low and high volume, fast turnaround production of injection molded parts. We ensure zero defect manufacturing through process-controlled methodologies. We sustain continuous operations by using microprocessor based, high-end CNC closed loop machines with capabilities from 20 tons to 200 tons.

Our molding expertise covers:-

  • Precision Components
  • Complex Profiles
  • Contoured Shapes & Fits
  • Precision Mechanisms
  • High Quality Cosmetic Finishes
  • Thin Wall Molding
  • Auto Unscrewing Mechanisms
  • Hot Runner Molds

Liquid Silicone Rubber (LSR)

LSR molding

The parts we manufacture have applications ranging from drug delivery such as primary drug packaging or wearable smart drug pump systems, fluid management, diagnostics, to biotechnology.

We support high production volumes that feature:-

  • “Flashless” molding
  • Complicated part configurations
  • Fast curing cycles
  • Class 8 clean room
  • Available press sizes: 20 - 80 Tons

High Consistency Rubber (HCR) & HTV

HCR / HTV molding

IRP understands the special considerations required to manufacture quality HCR silicone injection molded parts as it poses unique challenges compared to organic polymer-based rubber compounds. A wide array of colorings is possible.

Our capabilities include:

  • Low to moderate production volumes
  • Compression and transfer molding
  • White room molding

2-Component (2K) Parts, Over-molding, Bonded Parts

2K over-molding

We have experience with 2-component parts or over-molding silicone onto various plastic or metal parts. Through a highly specialized and automated process we carefully control the injection of multiple materials, including two different kinds of resin, into a single, multi-chambered mold.

  • Silicone or Rubber to Plastic
  • TPE to Plastic
  • Silicone or Rubber to Metal or Aluminum, etc.
  • Rubber to Rubber / Plastic to Plastic
