TPM Juarez: Large Tonnage Injection Molding Built for Scale, Complexity, and Partnership

As supply chains continue to reconfigure across North America, OEMs and Tier suppliers need more than raw press capacity for large, complex plastic components. They need a partner with proven experience, value‑added operations, and the agility to collaborate from design through steady‑state production. TPM’s Juarez, Mexico facility delivers exactly that—combining 1,400‑ton+ press capability, deep engineering support, and integrated assembly operations to help customers launch and sustain programs with confidence.

 

Facility Scale & Press Capability

Spanning approximately 65,000 sq. ft., TPM Juarez operates 35 injection molding presses from 35 tons to over 1,400 tons, including seven presses in the 500‑ton‑plus range. This breadth gives buyers real flexibility:

  • Capacity for large, structurally demanding parts that many suppliers can’t run
  • Ability to support multi‑press coordination for oversized enclosures and multi‑piece housings
  • A seasoned team with 16+ years producing large‑tonnage molded components, where dimensional stability, repeatability, and aesthetics are mission‑critical

 

Built for Large Parts (and Large Expectations)

TPM’s facility in Juarez routinely molds components exceeding one meter in length (approx. 110 cm) and has the discipline, tooling expertise, and production control to keep those programs stable. Typical deliverables include:

  • Multi‑press molding (top and bottom shells or multi‑piece enclosures)
  • Precision welding (vibration & ultrasonic) to ensure structural integrity and leak performance
  • Controlled‑torque fastening and repeatable sub‑assembly stations
  • Specialized leak testing (mass‑flow & leak‑decay) for engine‑adjacent or acoustically sealed applications

A representative example: a premium automotive audio enclosure molded as two large shells on separate presses, then welded, fitted with bushings and wire harnesses, and subjected to stringent leak testing. TPM’s end‑to‑end management reduces handoffs, protects quality, and tightens timelines.

 

Value‑Added Operations Under One Roof

To simplify supplier management, TPM Juarez consolidates molding with a full suite of in‑house secondary operations:

  • Vibration welding & ultrasonic welding
  • Mass‑flow & leak‑decay testing
  • Wire harness, bushing, bracket assemblies
  • Waterproofing & sound‑dampening membrane integration
  • Specialized screwing stations with controlled torque for repeatability

By handling these steps internally, TPM helps customers reduce logistics costs, minimize costs of quality, and gain a single accountable partner for complex programs.

“We are partners, it’s not only a customer supplier relationship, because at the end if they are successful, we are successful.” — Sergio Sanvicente, TPM Juarez, General Manager

 

Engineering Collaboration: DFM That Pays Off

The Juarez team engages early and often—from DFM reviews to resin selection and tooling feedback. That collaboration typically covers:

  • Gate placement, wall thickness, and flow optimization to balance aesthetics and mechanical performance
  • Material recommendations and substitutions for cost, weight, or durability
  • Tooling reviews & process refinement to enhance long‑term stability and reduce scrap

This partnership mindset means TPM doesn’t just “run the tool.” It helps improve the tool and the part—shortening learning curves, reducing risk, and accelerating the path to stable production.

 

Tooling Flexibility & Local Support

TPM Juarez welcomes customer‑owned tooling as well as TPM‑sourced tools. Every transferred tool undergoes a structured compatibility and standards assessment, including:

  • Press fit‑up checks
  • Water manifold verification
  • Locating features (e.g., V‑blocks) for repeatable positioning
  • Adaptations to TPM standards to ensure process consistency

Preventive maintenance and most rework are handled locally. For larger overhauls, TPM leverages a trusted partner in El Paso, Texas—keeping tools close, minimizing downtime, and avoiding unnecessary cross‑border moves.

 

Advanced Processing: MuCell® Microcellular Injection Molding

TPM continues to invest in technologies that improve performance and throughput for large‑tonnage programs. At Juarez, the team has conducted multiple trials using MuCell® microcellular injection molding (Trexel)—particularly on polypropylene, polycarbonate, and Lexan® parts.

While weight reduction is often associated with MuCell®, TPM has seen notable gains in cycle‑time efficiency and packing‑pressure control—advantages that directly improve cost and scalability for high‑volume programs. The team has already trialed seven part numbers, with additional evaluations planned as customer demand grows.

 

Markets & Applications

Large‑tonnage parts produced at Juarez are commonly found in:

  • Premium automotive audio systems (acoustic enclosures, large housings)
  • Engine‑adjacent components and structural covers for ATV/ORV and specialty vehicles
  • Industrial vehicle enclosures and assemblies

With northern Mexico expanding as a manufacturing hub, TPM Juarez is also exploring aerospace opportunities—bringing its discipline in precision molding, assembly, and quality systems to emerging programs in the region.

 

Strategic Location & Logistics Advantage

Situated in Juarez, Mexico, the facility sits at a logistics crossroads ideal for shipping across the U.S., Mexico, and international destinations. TPM supports returnable packaging solutions to lower freight costs, improve sustainability, and protect large components in transit—an approach already proven on programs shipping to Alabama, South Africa, Germany, and San Luis Potosí.

 

AI‑Enabled Operations: Planning, Forecasting & Process Optimization

TPM is actively exploring AI across three high‑impact areas:

  1. Production planning under real‑world constraints (press availability, tooling status, material flows), aiding schedulers in finding optimal run plans.
  2. Materials forecasting and sourcing scenarios, incorporating tariff changes and carbon‑footprint considerations to meet customer sustainability goals.
  3. Technical processing optimization, where multi‑variable models (e.g., shot size, wall thickness) are used to recommend efficient parameter windows—supporting faster set‑ups and better repeatability.

“You get an optimal processing set up from AI and we are exploring some of that technology to help us with advancing our efficiency through the use of AI in the set up of the equipment.” — Brian Marston, TPM, CEO and President

Additionally, TPM sees AI streamlining tool‑transfer intake, pre‑vetting opportunities via structured questionnaires (e.g., size, cavitation) so the technical team can focus on solutioning sooner.

 

Quality, Consistency & Risk Reduction

For buyers and sourcing leaders, TPM’s model reduces risk in three ways:

  • Integrated operations: fewer handoffs, tighter accountability
  • Engineering‑first mindset: early collaboration makes parts more manufacturable and tools more stable
  • Data‑driven processing: disciplined set‑ups, controlled torque assembly, and specialized testing yield predictable outcomes

The result: improved quality scores, smoother launches, and sustained performance throughout the life of the program.

 

A Flexible, Forward‑Looking Manufacturing Partner

Whether you’re transferring tools, consolidating supply, or launching new programs, TPM Juarez is open for business and built for scale. The plant’s combination of large‑tonnage capacity, value‑added assembly, engineering collaboration, tooling flexibility, and strategic location makes it a compelling choice for complex, high‑stakes programs in 2026 and beyond.
