Custom Plastic Products

From concept to completion, your single source for custom parts.

Thermoforming

Thermoforming: Process where sheets of plastic are heated to a pliable forming temperature, formed to a specific part shape on a mold, and trimmed to create a usable product. Includes vacuum forming, billow forming, and pressure forming.

Benefits
  • Inexpensive tooling compared to other plastic processes
  • Quick turnaround on pre-production prototypes
  • Small and large volume production
  • Multiple high-quality virgin thermoplastic options
  • Full scale secondary fabrication and assembly
  • Gemstar specializes in heavy gauge (.090 to .300) custom thermoforming
  • Stock and custom colors available
  • Our experienced workforce provides in-house tooling, design and knowledge of a wide range of thermoplastic materials, including ABS, acrylic, CAB, HDPE, Noryl, PC, PETG, PS and PVC alloy
Thermoforming
Vacuum Forming

Perfect for creating parts with uniform thicknesses at shallow depths

Pressure Forming

Compressed air is used to produce parts with greater definition and enhanced surface detail

Billow Forming

Uses a draw box to produce uniform wall thickness on parts with greater depths

Rotational Molding

A versatile process for creating unique, extremely tough parts in one-piece construction. Dry, powdered plastic is added to a closed mold and heated while rotating bi-axially. After cooling, the part is de-molded and ready for secondary operations.

Rotational Molding
Benefits
  • Unique shapes in one-piece construction
  • Rugged, stress-free parts
  • Faster tooling to production time frame
  • Full scale secondary fabrication and assembly
  • Small and large volume production
  • Ability to integrate metal parts and graphics
  • RoHS, fire retardant, medical, and food grade materials are available
  • Stock and custom colors available

Cold Forming

Polycarbonate is a rigid, clear, high-impact strength material. Its unique properties allow it to be bent and formed without the application of heat. Gemstar’s routing and fabrication capabilities are used to create complex parts for multiple custom applications.

Cold Forming
Benefits
  • Industrial equipment and housings
  • Medical equipment components
  • Instrument pieces
  • Electrical insulators and connectors
  • Aircraft and missile parts
  • Portholes in pressure chambers
  • Jet pump impellers and diffusers
