Five Star Fabricating provides engineering design support and prototyping for coated polycarbonate windows, thermoformed plastic parts, and composite components. We work with OEM engineers and product teams to help move parts from concept to production with better alignment to performance requirements, manufacturability, and production goals.
From early design input through prototype development and in-house tooling, our team supports programs that require optical performance, impact resistance, weight reduction, durability, and repeatable manufacturing. Whether the application involves transportation glazing, industrial equipment components, or specialty formed plastic parts, the focus is the same, develop components that are ready for production.
What happens next: Share your drawings, CAD files, or application requirements, and our team will review the design with you.
Engineering Support Aligned with Manufacturing
Effective design work should support what happens on the production floor. At Five Star Fabricating, engineering support is tied directly to the processes used to manufacture coated polycarbonate windows, thermoformed plastic parts, and composite components. By working with customers early in development, we can review part function, geometry, tolerances, materials, and downstream production requirements before tooling and full-scale manufacturing begin.
This early collaboration helps reduce development friction and supports a smoother path to prototype validation and production launch. It is especially valuable for components that must balance fit, finish, optical clarity, impact performance, environmental durability, and assembly requirements.
Our team works with a range of design workflows and file types to support efficient collaboration during development. Capabilities include CAD-to-CMM/DCC interface workflows, compatibility with DXF, EPS, IGS, DWG, JPG, and TIF files, and design platforms including AutoCAD and SolidWorks.
Prototyping for Fit, Function, and Production Readiness
Prototyping is a key step in validating how a component performs before production begins. Digital models can identify many design issues early, but physical prototypes are still essential for evaluating fit, function, manufacturability, and overall application performance.
Because Five Star designs and builds tooling in-house, prototype programs can move forward with tighter process control and more direct alignment between design intent and manufacturing execution. In-house tooling and master plug development help support close tolerances, strong surface quality, and efficient iteration as programs advance toward production.
This approach is particularly valuable for coated polycarbonate and thermoformed components, where forming method, trimming strategy, coating requirements, and final fit all influence production success.
What Five Star Helps Develop
Five Star Fabricating supports engineering design and prototyping for a range of high-performance plastic and glazing applications, including:
- Coated polycarbonate windows and formed glazing
- Thermoformed plastic components
- Composite panels and structural components
- Optical and impact-resistant parts
- Production-ready components for transportation, industrial, and specialty applications
These programs often require close coordination between design, tooling, forming, machining, coating, and finishing. Five Star’s process is built to support that transition from early design work to repeatable manufacturing.
Our Process
A clear development process helps keep programs moving and supports better production outcomes.
- Share Your Specs
Send your CAD files, drawings, performance requirements, or application details for review. - Design Review
We review part geometry, material considerations, tolerances, and manufacturability in relation to forming, trimming, coating, and production requirements. - Prototype Development
Prototype parts are produced to evaluate fit, function, and application performance before production. - In-House Tooling
Tooling and master plugs are developed in-house to support tighter control, efficient iteration, and production alignment. - Production Launch
Once the design is validated, the program moves into manufacturing with processes aligned to part requirements and production goals.

Why Early Design Collaboration Matters
Early collaboration between engineering and manufacturing can help improve both part performance and production efficiency. By reviewing the component before tooling is finalized, Five Star can help identify considerations related to:
- Material selection
- Part geometry
- Forming approach
- Tolerance requirements
- Surface finish expectations
- Secondary machining and trimming
- Coating compatibility
- Production repeatability
This is particularly important for applications involving coated polycarbonate glazing, thermoformed housings or panels, and composite components that must meet demanding performance and fit requirements.
Frequently Asked Questions
What is your typical prototype lead time?
Prototype lead time depends on part geometry, material, tooling complexity, and finishing requirements. Because Five Star designs and builds tooling in-house, prototype development can move more efficiently than programs that rely on outside tooling sources. Timing is reviewed based on the specific part and project scope.
Do you support confidential or NDA-driven projects?
Yes. Five Star works with OEMs and manufacturers on proprietary development programs and can support confidential project requirements.
How many prototype iterations are typical?
That depends on the design stage, component complexity, and validation requirements. During the initial review, the team can outline a prototype approach that aligns with the scope of the program and the intended production path.
What files can I send for a design review?
Five Star supports multiple file types for design collaboration, including DXF, EPS, IGS, DWG, JPG, and TIF, along with workflows using AutoCAD and SolidWorks.
Can you review a part for manufacturability before tooling begins?
Yes. Early design review helps identify opportunities related to material choice, forming strategy, tolerances, trimming, coating requirements, and overall production efficiency.
Do you build tooling in-house?
Yes. In-house tooling is a core part of Five Star’s development process and supports prototype development, process control, and a more efficient transition into production. This significantly reduces lead times and allows for immediate adjustments during the prototyping phase.
