Custom Plastic Profile Extrusion
Based in Middlefield, Ohio, Plastic Extrusion Technologies manufactures custom plastic profiles for B2B companies throughout the United States, from Fortune 500 manufacturers to first-time inventors.
We produce profiles from 1/32″ to 13″ in cross-section across a wide variety of resins, to the exact dimensions your application requires, whether the project is a prototype run or full-scale production.
And before we cut a single die, our team reviews your design for extrusion compatibility, so the profile you receive is easier to produce, more consistent run after run, and less expensive to manufacture.

Extruded Plastic Profiles & Shapes
- Channels and U-channels for framing, edge protection, and track systems
- Angles and L-shapes for structural support, trim, and corner guards
- T-shapes and H-shapes for joining, dividing, and connector applications
- Caps and edge trim for panel systems, finished edges, and gasket housings
- Multi-cavity and hollow profiles for complex structural, HVAC, and enclosure applications
- Fully custom geometries when no standard shape meets the design requirement
If you can draw the cross-section, we can extrude it. Our team regularly produces profiles that other manufacturers turn away, including complex wall thicknesses, tight internal radii, and multi-leg geometries, run after run, to spec. If another extruder told you a profile couldn’t be produced, talk to us. We’ve solved problems that other shops walked away from.
Engineering Support Before Production Starts
The most expensive profile problems are the ones discovered on the production line. Ours are caught at the design stage. With 100+ years of combined extrusion experience, our engineering team gets involved before the first piece of tooling is cut, ensuring the design is right before production starts and you’re not solving problems on the line.
Customers come to us with a wide range of starting points: a finished engineering print, a hand sketch, or a physical sample from an existing part. Whatever the starting point, our review process is the same. We look at every design through the lens of what will extrude cleanly, maintain consistent tolerances, and produce the result you’re expecting.
Design Review for Extrusion Compatibility
We review wall balance across the profile, flag features such as sharp corners that are difficult to hold in the extrusion, and sometimes recommend breaking a large, complex profile into components that assemble cleanly after the run. A profile with dramatically different wall thicknesses runs slower, bows, and drifts out of tolerance. When we balance those walls, the result is a better-looking part, a more consistent run, and a lower per-unit cost.
Material Guidance that Changes the Economics
When the material you’ve specified isn’t the right fit, we’ll say so. Our team asks the right questions up front, and in roughly 25% of projects, a conversation about material leads to an equivalent or better result at a meaningfully lower cost. When wall thickness or structural requirements still need validation, we can often provide a physical sample from existing stock so you can test before tooling begins.
In-House Die Design & Tooling Adjustments
We design our dies here and resolve about 98% of tooling issues in-house, without a second tool. That means lower costs and less waiting for you, with fewer delays in sending a die back to an outside toolmaker. In the uncommon case where a redesign is needed, we look for ways to reuse existing tooling components to keep costs down.
Material Integrity, Start to Finish
When we design a die for a specific resin and grade, we hold to it. A different grade can mean parts that won’t weld, won’t fit, or won’t perform, even when the material looks similar on paper. We maintain multiple vendors to ensure supply reliability, but the grade we quoted won’t change without a conversation. What we quoted is what runs.
Our goal at every stage is the same: know everything about your part before tooling starts, including how it functions, where it takes load, what the finish requirements are, and how it fits with mating components. That conversation up front is what prevents problems down the line.
Customization From Every Angle
Every profile we produce starts with your specifications. We do not sell stock shapes. We work from your drawings, consult on your design to make it more extrusion-friendly, and manufacture to the exact requirements of your application.
Profile Size Range
We produce profiles from 1/32″ to 13″ in cross-section. Whether the part is a narrow edge trim or a wide structural channel, our multi-line operation handles it.
17 Resins Available
Rigid PVC, flexible PVC, HDPE, polypropylene, ABS, acrylic, polyurethane, HIPS, Noryl, TPR, wood-filled compounds, nanocomposites, and more. If your application has specific requirements regarding rigidity, flexibility, chemical exposure, temperature, or UV stability, our team can advise on the right material before production begins and will flag a lower-cost option that performs equally well when one exists.
Tight, Repeatable Tolerances
Dimensional consistency is not a first-article result. It is what we hold across every production run, which starts with a die designed for your exact profile and a wall layout balanced to run clean.
Color & Surface Finish
Custom color matching is available across our resin range. Surface finish requirements are addressed in the die design process, before the line runs.
Any Volume. No Minimum.
We do not have a minimum order requirement. If you need a small prototype run to verify fit and function before committing to production, we will produce it. When you are ready to scale, we will already know your profile, tooling, and tolerances.
For ongoing production accounts, our 45,000 sq. ft. facility processes over 7 million pounds of plastic per year, with an additional 10,000 sq. ft. of warehousing to support scheduled programs and just-in-time fulfillment. Customers range from individual inventors bringing a new product to market to enterprise manufacturers sourcing at volume. Both get the same attention to quality and delivery.
Secondary Finishing Included
Most extrusion manufacturers deliver a raw profile. We go further. Secondary finishing is part of our production process, so the part you receive is ready to install, assemble, or ship. Available finishing operations:
- Notching and drilling for mounting, fastening, and assembly requirements
- Punching for precise, repeatable hole patterns along the profile length
- Forming for bending or shaping profiles to specific angles or curves
- Gluing and taping for adhesive-backed applications and multi-component assemblies
- Heat welding for joining profile sections where mechanical fastening is not the right solution
Industries & Applications
Custom plastic profiles are used across nearly every manufacturing and construction sector. We regularly produce profiles for:
- Commercial construction, including window and door trim, framing channels, glazing systems, and architectural profiles
- HVAC, including duct trim, sealing profiles, insulation channels, and access panel framing
- Refrigeration, including door frame profiles, gasket retainers, breaker strips, and shelf supports
- Point of purchase and retail display, including sign holders, shelf dividers, label channels, and display framing
- Brush manufacturing, including channel strip brush backings and retainer profiles
- Cable and wire management, including conduit, trunking, and organizational profiles
- Safety applications, including floor trim, edge guards, and protective profiles
New applications come in regularly. If your industry is not listed here, that is not a limitation. It is a conversation we have not had yet.
Why P.E.T. for Custom Plastic Profile Extrusion
100+ years of combined engineering experience. Our team advises before production starts. We review your profile design for manufacturability, identify tolerance risks, and suggest changes to geometry or materials that improve performance or reduce cost. We catch unbalanced walls, oversized profiles that run better as separate components, and sharp corners that won’t hold tolerance early on, recommend adjustments, and explain the trade-offs. That engineering input is uncommon in custom extrusion and consistently saves customers time and money.
Complex profiles are standard work here. We produce simple and highly intricate geometries with the same consistency: multi-cavity profiles, thin-wall sections, parts with tight internal features, and profiles requiring coextrusion to achieve different material properties in different zones. Complexity is not a reason to decline a project. If another shop turned your part away, that is often exactly the kind of work we take on.
Tooling handled in-house. We design our dies here and resolve roughly 98% of tooling issues without a second tool, which means fewer surprises, lower retooling costs, and shorter lead times when a die needs adjustment after the first run.
Any account size, any volume. We work with first-time buyers developing a new product and with enterprise purchasing teams sourcing for high-volume operations. No minimums, no account size thresholds, no point at which a project is too small to take seriously.
A finished part, not a starting point. Tooling, extrusion, and secondary finishing under one roof means fewer vendors, fewer handoffs, and a part that arrives ready to use.
Partnership, not just production. Customers consistently describe working with P.E.T. as a partnership. We have relationships spanning decades, earned the same way every time: responsive to urgent requests, consistent in quality, and present from the first prototype through every subsequent production run.
