Injection Molding Inserts

The tight-tolerance low cost alternative to machined inserts

Stripmatic has developed a manufacturing process to make inserts that will hold up to the molding process, prevent ID seepage and be less expensive than machined inserts.

Tight-tolerance injection molded inserts from Stripmatic offer:

  • 100% guaranteed closed seams to eliminate seepage during the molding process
  • Flat and parallel rolled or machined ends for a complete seal to prevent seepage during the ID
  • Knurled or indent pattern on the OD can often be used to help reduce the molding cycle time and to prevent distortion as the part is injected
  • Chamfer details can be designed to seal off the mold flush on the OD and create a lead edge on the ID for improved bolt location
  • Can use range of materials or may be plated for corrosion resistance

Tight Tolerances

  • Consistent OD and length tolerances improve mold cycle times and finished part quality
  • Concentricity of part will help maintain centerline to centerline dimensions
  • This process can meet or exceed axial load design requirements

Cost Savings

  • Shorter lead times and less price volatility than inserts machined from tubing
  • Most features are performed in-process vs costly secondary operations

Solid Experience - Fast Response

  • Quick prototype and sample turnaround
  • Exceptional track record for quick response time on quality issues
  • EDI and CAD technical support
  • Inventory control using customer-based inventory management systems
  • Over 60 years of wrapped tube technical support
