Making FRP Parts
Once you have a highly accurate mold, manufacturing your product becomes a lot easier. We can help you get the solid start your business needs. Our fiberglass mold-making abilities span the gamut and we’re always happy to discuss the correct methodology and approach for your project. Our abilities include:
- Hand Lay-Up:
This open-molded process relies on a single-side mold, where fiberglass is applied by hand, then saturated with a liquid polymer to form a laminate. - Spray-Up Process:
Another open-molding process, spray-ups are done via a chopper gun and random orientation fiber, which allows the mold to be more intricate. - Vacuum molding:
Instead of pressure, this closed-molding technique pulls in resin through a vacuum to quickly and accurately form a molded object. There are several variations on this method.
Let the EJ Painting & Fiberglass Inc team put our experience and extensive capabilities to work for you when it comes to fiberglass mold-making, design, and creation. Reach us today at 303-288-8373 to discuss your project and let us help you decide the right course of action for creating ideal custom fiberglass molds, gel coatings, and fabrication.
FAQs
1. How durable are fiberglass and composite parts?
Fiberglass composites offer excellent corrosion resistance, high strength-to-weight ratio, and long service life. Properly maintained, our parts can last decades even in harsh outdoor or chemical environments.
2. What is the typical wall thickness of an EJ Fiberglass part?
Most fiberglass parts range from 1/8″ to ½″ depending on structural requirements.
We tailor thickness based on mechanical load, environmental exposure, and weight constraints.
3. Can EJ Fiberglass replicate or reverse-engineer an existing part?
Absolutely. If you provide a physical sample, we can 3D-scan or pattern it to replicate the geometry. This is common for legacy parts where no CAD data exists.
4. What is the difference between a “pattern,” “mold,” and “part”?
Pattern (Plug): The original prototype or master shape used to form the mold.
Mold (Tooling): The negative form built from the pattern; used for production.
Part (Child Part): The final fiberglass product formed inside the mold.
Each stage builds on the previous one to ensure precision and repeatability.
5. What determines fiberglass part pricing?
Fiberglass part pricing is driven by:
- Material type (resin system, reinforcement fabrics, gelcoat)
- Complexity and size of the part
- Quantity ordered (economies of scale)
- Surface finish and paint requirements
- Whether new tooling is required
We provide detailed quotes that break out one-time tooling costs from per-part production pricing so clients can budget accurately.
6. Does EJ Fiberglass provide engineering or design assistance?
Yes. Our team routinely collaborates with engineers, architects, and artists to refine designs for manufacturability. We can adjust draft angles, wall thickness, and parting lines to ensure efficient mold release and long-term durability.
