Rebuild or Manufacture New?
The right approach depends on component condition, application requirements, and production objectives.
Rebuild Existing Component
- Reduce cost compared to new manufacturing
- Restore hard-surfaced wear areas
- Correct dimensional wear
- Improve mixing and output performance
- Minimize production downtime
Manufacture New Component
- Replace heavily damaged components
- Update screw geometry for new applications
- Adapt to different processed materials
- Resolve recurring performance limitations
- Manufacture to print or custom specification
Industries Served
Supporting plastics processing operations across multiple industry segments.
Injection Molding
Screw and barrel condition directly affects shot consistency, cycle time, melt homogeneity, and part quality in injection molding operations.
Extrusion
Extruder screw geometry and barrel condition determine output rate, melt temperature, pressure stability, and product uniformity.
Compounding
Distributive and dispersive mixing quality depends on screw design, flight geometry, and mixing section configuration.
Blow Molding
Parison quality and wall thickness distribution are influenced by melt consistency delivered by the extruder screw.
Packaging
High-volume packaging production requires consistent output, tight temperature control, and reliable screw performance.
Automotive Plastics
Engineering-grade polymers used in automotive components demand precise melt processing and wear-resistant screw surfaces.
Industrial Plastics
Industrial applications require durable components and screws designed for abrasive or corrosive processing environments.
Rubber Processing
Rubber extrusion and molding require specialized screw designs for proper material handling, mixing, and temperature management.
Custom Polymer Processing
Specialty polymers and custom formulations benefit from application-specific screw geometry and process consultation.
