Precision Engineering for Continuous Performance
At Technical Process & Engineering, Inc. (TPEI), we build and support the machinery that keeps your production running — from continuous mixers and extruders to complete turnkey compounding systems.
High-Performance Continuous Mixing
TPEI’s continuous mixers are built for performance, durability, and flexibility across a wide range of compounds.
- Short L/D ratios optimized for high-filler applications.
- Proprietary Free Rotor™ (FR) and Extended Rotor (FRE) designs.
- Fast, Class “A” cleanouts to minimize changeover downtime.
- Compact chambers engineered for temperature and residence-time control.
- Fully automated systems for consistent throughput and quality.
Result: cleaner mixes, higher output, and reduced maintenance cycles.
Integrated Extrusion & System Upgrades
Our extruders are engineered for efficiency and seamless integration with new or existing equipment.
- Standard 10:1 L/D ratio with dual temperature zones for precise control.
- Variable speed AC motors and drives for optimized process windows.
- Custom J-Block™ Feed Throat technology for uniform feed and stability.
- Grooved barrels with Inconel® tubing to enhance thermal management and wear life.
- Options for screen changers, pelletizing systems, and downstream transitions.
Result: higher consistency, improved product quality, and longer equipment life.
Rebuilds, Retrofits & Turnkey Systems
When performance declines or capacity must increase, TPEI provides rebuilds, retrofits, and complete compounding systems that restore or exceed original performance — without starting from scratch.
Restore & Extend Equipment Life
OEM-quality parts and rebuild services bring aging machinery back to peak performance.
- Complete machine rebuilds — mechanical, electrical, and controls.
- Component rebuilds and rotor restacking to original specifications.
- Chamber liner replacements for extended wear life and protection.
- Gearbox rebuilds, alignment checks, and precision balancing.
- In-house spare part manufacturing for rapid turnaround.
Result: extended lifecycle, lower ownership cost, and maximized uptime.
Complete Compounding Lines
From feed to finished product, TPEI designs and delivers complete, integrated systems.
- Full system design, layout planning, and line elevations.
- Custom control panels and automation tailored to your process.
- Conduit and wiring set up for plug-and-play integration on site.
- Factory assembly and test-run prior to shipment for smoother startup.
- On-site assembly and system startup typically within two weeks of delivery.
Result: ready-to-run lines that shorten installation time and accelerate production efficiency.
Technical Support & Field Service
Downtime isn’t an option. TPEI backs every system with responsive support, field service, and long-term partnership.
Keep Your Lines Running
- 24/7 emergency service for critical breakdowns and line-down events.
- Laser alignment for optimized machine performance and reduced wear.
- Process audits and corrective action plans to stabilize production.
- Remote support, diagnostics, and parameter guidance.
- Operator training and maintenance best practices.
Result: continuous performance, fewer unplanned stops, and total peace of mind.
