Products and services

• Pressure Forming A thermoforming process that uses positive air pressure to form heated plastic sheets against a mold, enabling high-detail parts with sharp definition and cosmetic finishes comparable to injection molding. Offered to OEM and POP customers requiring cosmetic exterior parts.
• Vacuum Forming A thermoforming process where heated plastic sheet is drawn into a mold using vacuum pressure, suitable for lower-volume production and simpler part geometries. Used for OEM components across multiple industries.
• Rotary Forming Continuous rotary thermoforming process for high-volume production of identical parts with efficient cycle times. Used for OEM runs requiring consistent, repeatable output.
• Single Station Forming Batch thermoforming process using single-station equipment for moderate production volumes and flexibility in part size. Used for OEMs needing mid-volume runs.
• CNC Trimming Computer-controlled routing and trimming of thermoformed parts using 7 CNC routers (including five-axis machines) for precise dimensional accuracy and consistent finish on OEM parts.
• Robotic Trimming Automated trimming using 4 robotic trimming stations for high-volume production with consistency and reduced labor costs on OEM parts.
• Aluminum Castings for Production Tooling
