Our Capabilities

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.

For over 30 years, manufacturers have relied on our engineering expertise, rebuild services, and 24/7 support to minimize downtime, extend equipment life, and maximize throughput across plastics, rubber, and recycling applications.
Continuous Mixers

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.

Extruders & Retrofit Solutions

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.

Lifecycle Services

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.

Rebuilds & Spare Parts

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.

Turnkey Systems & Custom Engineering

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.

Support & Partnership

Technical Support & Field Service

Downtime isn’t an option. TPEI backs every system with responsive support, field service, and long-term partnership.

Technical Support & Field Service

Keep Your Lines Running

  • 24/7 emergency service for critical breakdowns and line-down events.
