Custom Fiberglass Manufacturing and Mold Making Services

Custom fiberglass manufacturing creates unique parts by molding glass fibers with resins. Manufacturers can tailor thickness, color, strength, and shape. As a result, a wide range of applications can benefit from highly precise molding and fabrication, from aircraft components to aerospace parts. The process concludes with finishing and trimming, resulting in a component that is not just a raw shell but a custom solution tailored to your operational environment.

At CMDT Manufacturing, we provide complete custom fiberglass fabrication and mold making services, handling everything from initial design consultation and pattern development through mold creation, fabrication, finishing, and field installation. If you know what the part needs to do but aren’t sure how to get from a sketch or STEP file to a complete fiberglass part, that’s where we come in.

Custom Fiberglass Fabrication

Fiberglass is highly versatile. It can be molded into intricate, complex shapes that are difficult to achieve with other materials. Additionally, its lightweight strength and durability make it ideal for wind turbine blades, vehicle parts, and airplane components, as well as tanks, pump skids, and fittings. Techniques such as hand lay-up, spray-up, or vacuum infusion can be used to meet different strength requirements and volume needs.

Custom Fiberglass Fabrication

At CMDT, our team of fiberglass fabricators has the experience and resources to take your specifications and turn them into precision-engineered parts built for demanding industrial environments. We fabricate parts for industrial equipment, aviation components, wastewater treatment systems, pool and spa accessories, municipal infrastructure, and more.

Our fabrication capabilities include:

Low to high-volume production

Each project starts with understanding your environment: corrosive chemicals, high temperatures, structural loads, and more, so we can recommend the right materials and construction methods. Learn more about our fiberglass fabrication process.

CNC Mold Making Services

Different types of molds can be used in fiberglass production, including simpler two-dimensional molds that can be used with parts like fiberglass boat hulls, and closed molds, which are typically used for components requiring smoothness on both sides and a high degree of precision. 

CNC Mold Making Services

Our in-house mold making services build on vast design engineering experience. This along with the latest technology and techniques enables us to create molds with intricate details and complex geometries.

We can utilize the following to provide molds that meet your specific requirements:

Pattern development from STEP files or physical samples

This integrated approach reduces your upfront costs and project timeline. Further, subsequent production runs with existing molds generally ship in just 1–2 weeks.

Material Expertise

At CMDT ManuA key factor to consider during mold making is materials, including fabrics and resins. For fiberglass mold making, this involves selecting materials based on production volume and finish needs, layering for the right thickness and build, and ensuring proper ventilation and temperature control during application to allow for optimal curing and finish.

facturing, we source and work with various fiberglass resin systems to match your application requirements:

  • General-purpose resins. Cost-effective for standard industrial applications.
  • High-temperature resins. For environments exceeding standard thermal limits.
  • Vinyl ester resins. Superior chemical resistance for aggressive environments.
  • Custom resin formulations. Sourced as needed for specialized requirements.

Foam stiffener core materials add structural rigidity where needed without excessive weight. This material expertise allows us to recommend the most appropriate construction method for your specific use case.

Field Service Work

Field Service Work

We provide field service work throughout North Texas for installation, repair, and modification projects. This service extends to many different fiberglass components, regardless of whether we originally fabricated them.

On-site services include:

  • Installation and assembly
  • Structural repairs and modifications
  • Gel coat restoration and refinishing
  • Emergency repair response
  • Preventive maintenance

Our field technicians understand fiberglass behavior in real-world conditions. We’ve repaired cracked valve boxes at wastewater facilities, refinished pool equipment enclosures, and modified industrial hoppers to accommodate changed processes. When downtime costs money, our response gets systems back online quickly.

This capability is particularly valuable for facilities that can’t ship large assemblies off-site or need modifications completed during scheduled shutdowns.
