HCR Transfer Molding

QSR specializes in transfer molding using high consistency rubber to produce micro to mid-sized products. The process uses the latest cold pot technology to minimize process waste and create more cost-effective end products.

Utilizing standard tool sizes and inserted tooling while employing quick cycle times is the goal.

Our expertise also includes development and molding of specialty silicones for custom solutions.

Consider HCR Transfer Molding for these products:

  • Ignition insulators
  • Connectors
  • Wire seals
  • Grommets
  • Cable seals
  • Interfacial seals
  • Gaskets
  • Boots
  • Additional products based on customer needs – just ask!

Liquid Injection Molding

State-of-the-art liquid injection molding (LIM) machines are automated to run faster than other processes and reduce labor costs on custom parts.

While LIM is ideal for processing a wide array of liquid silicone rubber (LSR), it is typically selected based on material requirements. QSR’s capabilities extend to low volume LIM production as well (see Custom Volume Production).

Consider Liquid Injection Molding for these products:

  • Open center seals
  • Gasket type parts
  • Additional products based on customer needs – just ask!

Rubber Overmolding

Continuing investment in engineering, technical expertise and product development, especially in the manufacture of two component (2K) or rubber overmolding projects for custom and off-the-shelf applications, is what sets QSR apart from the competition.

Choose either HCR transfer or liquid injection molding (LIM), depending on your requirements and the application. Either one can produce parts with the rubber chemically bonded to a metal or plastic insert.

QSR’s proactive approach and major investment in proprietary adhesion test mold and methodology ensures proper validation for numerous substrates and elastomers used in both HCR and LSR processes.

Consider QSR’s rubber overmolding capabilities especially for:

  • Ignition insulators
  • Cable seals
  • Additional products based on customer needs – just ask!

Custom Volume Production

QSR offers low to mid-volume production capabilities mirroring our full-scale manufacturing operations and using the same exceptional tooling strategy to yield tight tolerance, flashless part prototyping and short runs. Capabilities also include secondary operations such as post treatments and pad printing.

Implemented in 2010 with four 100 ton transfer presses, our low to mid-volume area now supports seven prototype specific presses, eleven transfer presses ranging from 50 ton–250 ton and three new liquid injection presses.

Consider QSR’s low to mid-volume capabilities for components used in these industries:

  • Aerospace
  • Industrial
  • Automotive
