Custom Plastic Extrusion Solutions:

Beyond our expansive logistical footprint and rapid turnaround times, our true value lies in the intersection of material science and precision engineering. We don’t just manufacture profiles; we engineer solutions that optimize your product’s performance. By leveraging our deep technical bench and diverse material portfolio, we bridge the gap between initial design concepts and high-efficiency manufacturing through the following advanced extrusion techniques.

Advanced Extrusion Techniques & Engineering

We specialize in advanced extrusion techniques designed to maximize part functionality while lowering the total cost of ownership. By maintaining tight tolerances of +- 1% and leveraging a versatile fleet of single-screw (1″ to 4″) and high-performance twin-screw extruders, we deliver precision across a vast scale. Our team manufactures custom plastic profiles ranging from intricate components under 0.25″ to large-scale profiles up to 12″ in width.

Ideal for engineered designs requiring multiple material properties (such as rigid and flexible durometers) in a single, streamlined production part.

A specialized method for high-volume, thick-walled parts. This process reduces part weight and material costs while enhancing thermal and acoustic insulation. We can produce celuka foam (hard skin – better for strength and screw strength retention) or free foam that produces a lighter lower cost part that is primarily used for trim moldings or low voltage wire harness.
By running identical profiles simultaneously from a single die, we double production capacity and significantly lower the per-unit cost for our clients.
Whether you have a low-volume specialty run or a high-volume requirement, we can offer multiple tooling options to balance upfront investment with long-term production savings. We can design simple tooling using minimal die and forming plates or extensive sophisticated streamlined tooling with elaborate vacuum calibration systems for maximum throughput rates.

Custom Extrusion Tooling & Precision Die Manufacturing

At Barbour Plastics, we accelerate the transition from concept to production by integrating engineering collaboration with high-precision die fabrication under one roof. Our process is designed to reduce development risk, improve manufacturability, and ensure dimensional accuracy from the very first production run.

By aligning your engineering team with our tooling specialists early in the design phase, we eliminate uncertainty before steel is cut. This proactive, hands-on approach shortens development timelines, improves first-article success rates, and minimizes costly die revisions—allowing for a smoother and more predictable transition into full-scale extrusion production.

Before committing to production tooling, we mitigate risk through functional prototyping. We provide 3D printed profile samples within 24 to 48 hours of design approval, giving your team the ability to physically evaluate form, fit, and function in a real-world application.

Unlike competitors who require design finalization based solely on 2D drawings, our process bridges the gap between design intent and manufacturability. By validating performance early, we significantly reduce the need for secondary die modifications and help you move to production with confidence.

While many extruders outsource their die construction to third-party machine shops—leading to communication gaps and shipping delays—Barbour Plastics maintains a full-service, in-house tooling facility.

  • Precision Engineering: We utilize advanced 4-Axis Wire EDM (Electrical Discharge Machining) and high-speed CNC centers to cut dies from premium tool steel.
  • Exact Tolerances: Our in-house process allows us to maintain tolerances as tight as ±.001″ on critical die geometry, ensuring consistent wall thickness and profile integrity throughout long production runs.

We provide the transparency required for project planning and capital budgeting. While complexity dictates final pricing, our standard benchmarks include:

MetricTypical Range / Benchmark
Prototype Print Turnaround24 – 48 Hours
Custom Tooling Lead Time3 – 5 Weeks (Standard)
Ballpark Tooling Costs$2,500 – $15,000 (Depending on complexity)
Expedited ToolingAvailable for critical-path projects

Versatile Solutions Across Every Industry

Since our start in the 1970s—pioneering PVC rub rails for the marine industry—we have expanded to serve nearly every sector of American manufacturing. By controlling the tooling process from the first CAD file to the final polished die, we ensure a “right the first time” launch for every profile we pull.

How is Barbour Plastics Different From Other Extruders?

Unlike traditional manufacturers, we prioritize personal communication and teamwork. We operate under the belief that the most efficient manufacturing occurs when there is total transparency between our team and yours. While other extruders may struggle with consistency, we utilize a “start-to-finish” process built on rigorous quality redundancies. This ensures that every part is not only delivered on time but remains strictly within your required tolerances. We take an active role in your project’s success by welcoming buyers and engineers—especially those new to the field—to tour our facility. We don’t just take orders; we guide you through achieving economies of scale and smart inventory management to ensure your project is as cost-effective as possible. Barbour Plastics manages the heavy lifting of seamless integration. From the initial calibration on our production lines to final delivery at your door, we handle the technical hurdles and logistics so you can maintain focus on growing your business.

Frequently Asked Questions (FAQ)

Custom plastic extrusion is a manufacturing process used to produce continuous plastic profiles with a fixed cross-section tailored to your specifications. At Barbour Plastics, we engineer thermoplastic profiles based on your CAD files, dimensional requirements, material performance needs, and production volume. Our in-house tooling and precision calibration systems ensure consistent wall thickness, tight tolerances, and repeatable quality from first article to full production.
We extrude a wide range of thermoplastics, including PVC (rigid and flexible), Polycarbonate, HDPE, LDPE, Polypropylene, ABS, Acrylic, and Cellular Foam (Celuka and Free Foam). Our team helps select the optimal material based on strength, UV resistance, chemical exposure, insulation value, cost targets, and end-use environment.
Our standard custom tooling lead time is 3–5 weeks, depending on profile complexity. Because we manufacture dies in-house using CNC machining and Wire EDM, we eliminate third-party delays and maintain tighter control over scheduling, quality, and precision.
We maintain profile tolerances of approximately ±1%, with critical die geometry held as tight as ±.001″ during tooling fabrication. This ensures dimensional stability, consistent wall thickness, and repeatability during long production runs.
Co-extrusion (and tri-extrusion) allows multiple materials to be combined into a single profile during production. This enables the integration of rigid and flexible sections, UV-resistant caps, color layers, or impact-modified surfaces in one streamlined process. By eliminating secondary assembly and reducing material waste, co-extrusion lowers total cost of ownership while improving part performance.
Tooling costs typically range from $2,500 to $15,000, depending on profile size, complexity, calibration requirements, and vacuum forming systems. We offer flexible tooling strategies to balance upfront investment with long-term production efficiency and scalable output.
