From concept to physical prototype — CAD design, DFM review, and rapid prototype manufacturing in plastic and metal, all under one roof.
Turning an idea into a manufacturable part requires more than a good design — it requires a manufacturing partner who understands how materials behave, where designs can be simplified, and how to get a functional prototype in your hands as fast as possible. Plastic-Craft provides end-to-end support from initial CAD design through rapid prototype production, helping engineers and product teams move from concept to testable part with confidence.
Rapid prototyping is the process of quickly producing a physical part or assembly from a digital design — typically a 3D CAD model — for the purpose of testing form, fit, and function before committing to full production tooling or volume manufacturing. Unlike production manufacturing, rapid prototyping prioritizes turnaround time and design flexibility over cost-per-unit.
Not every project arrives with a complete, production-ready CAD file. Our design team works with engineers, product developers, and procurement teams at every stage of the design process.
Have an idea, sketch, or reference sample but no digital file? Our team develops a manufacturable 3D CAD model from scratch — built with your target manufacturing process and material in mind from the start.
Have an existing CAD file? We review it for manufacturability and prepare it for your chosen process — CNC machining, thermoforming, laser cutting, injection molding, or another capability in our facility.
Design for Manufacturability review evaluates your part against the constraints of your manufacturing process. We review wall thickness, draft angles, radii, tolerances, and material selection — flagging issues and recommending changes that reduce cost and improve quality.
As prototype testing reveals improvements, we support rapid design iteration — updating CAD files and turning around revised prototypes quickly so your development cycle keeps moving.
File formats accepted: STEP, IGES, SolidWorks (.sldprt/.sldasm), AutoCAD (.dwg/.dxf), PDF for 2D reference. Contact us if your format is not listed.
We produce prototypes using the same equipment and processes used for production — which means your prototype is made in the actual material and process your final parts will use, not a simulation of it.
CNC Machined Prototypes — Prototypes machined directly from solid plastic or metal stock. The preferred method when dimensional accuracy, surface finish, and true material properties are critical. Available in virtually all plastics in our portfolio plus metal.
Thermoformed Prototypes — For parts destined for thermoformed production, prototype tooling is fabricated quickly at lower cost than production hard tooling — enabling accurate prototype parts in the actual forming process and material.
Laser Cut & Fabricated Prototypes — Flat and near-flat parts — panels, brackets, enclosures, templates — prototyped rapidly using laser cutting and secondary fabrication. Fast turnaround and low cost for flat-profile designs.
Assembled Prototype Sub-Systems — When a project involves multiple components — plastic parts, metal hardware, fasteners, adhesive bonds — we prototype the full assembly, not just individual parts.
All 21 plastics in our portfolio are available for prototype production, including:
Acrylic (PMMA), Polycarbonate (PC), Acetal/Delrin (POM), Nylon (PA), UHMW Polyethylene, Polyethylene (PE), HDPE, PVC, Phenolic, Hydlar Z (Kevlar-filled Nylon), Noryl (PPO), PEEK, PETG, Polypropylene (PP), Polystyrene (PS), Polyurethane (PU), Teflon (PTFE), Torlon (PAI), Ultem (PEI), Vinyl, Vespel (PI)
Metal prototypes are also available. Contact us to discuss your alloy and specification requirements.
One of the most significant advantages of prototyping with Plastic-Craft is that your prototype and your production parts come from the same facility, using the same equipment and the same team. There is no handoff to a separate production supplier — no re-quoting, no re-tooling surprises, no material substitutions.
When your design is validated and approved, production scales up within our existing workflow. This continuity reduces lead time and eliminates the quality and tolerance variations that can occur when switching manufacturing partners between development and production phases.

A prototype is produced for testing, validation, or demonstration — typically in low quantities and often from simplified tooling. A production part is manufactured to volume specifications using production-grade tooling and process controls. At Plastic-Craft, many prototypes are machined from production-grade materials using the same equipment as production, so the distinction is primarily about quantity and tooling — not material or process quality.
Lead time depends on part complexity, material, and quantity. Simple machined prototypes in standard materials can often be turned around in a matter of days. More complex parts, special materials, or assemblies requiring multiple components will take longer. Contact us with your project details for an accurate lead time estimate.
Yes. Because we produce prototypes using subtractive machining and forming processes rather than 3D printing substitutes, we can prototype in the actual material your final production parts will be made from — including high-performance engineering plastics such as PEEK, Torlon, Ultem, and Vespel. This is particularly important for functional testing under real service conditions.
STEP files are preferred for 3D geometry as they are universally compatible with our CAM software. DXF or DWG files are accepted for 2D profiles. If you only have a PDF drawing or a physical sample, contact us — we can often work from drawings or reverse-engineer from a sample part.
Yes. We provide DFM (Design for Manufacturability) review as part of our standard quoting process for new parts. If your design has features that may cause issues — thin walls, sharp internal corners, undercuts, or other geometry concerns — we will flag them and recommend modifications before cutting the first prototype.
Online 3D printing services produce prototypes from materials that simulate production plastics but are not identical in mechanical properties, chemical resistance, or dimensional stability. Plastic-Craft prototypes are machined or formed from the actual production material — giving you test results that reflect real-world performance. Additionally, because we handle both prototyping and production, your transition to volume manufacturing happens within the same facility with no supplier change.
