Thermoset Capabilities
Century Composites, LLC also specializes in Thermoset Fiberglass Reinforced Plastic (FRP) production. We specialize in hand lay-up, spray-up, resin transfer molding (RTM), and compression molding using polyester, vinyl ester, and epoxy resins.

Hand Lay-Up and Spray Up
One of the most basic of FRP manufacturing processes, Hand Lay-up involves applying and forming each resin/glass laminate layer manually into an open mold until the desired part thickness is achieved. Because of the close control of material application, it is the method of choice for producing many fiberglass parts.

In Spray-up manufacturing, a mixture of chopped glass fibers and resin is sprayed onto a mold to form the part shape. Due to its high material application rate, spray-up is an economical method for manufacturing certain fiberglass parts. Parts requiring large area coverage, moderate strength and corrosion resistance as well as fast production rates are produced using this Spray-up technique.

Compression Molding
Matched die molding of a premix paste of chopped glass reinforcement and resin is called Compression Molding. This process is widely used to manufacture parts in situations where large production quantities offset the method's increased cost of tooling.

Design and Engineering
Our team of engineers and technicians possess the skills and experience to guide your project from start to finish. The facilities have a comprehensive array of engineering software and hardware needed to assist in product development.

Tooling is produced in-house from AutoCAD or ProE design drawings, or from 3-D scans of existing parts. Designs are transferred directly to CNC machines for rapid precise production of mold components and cavities.

Thermoplastic Services
Our 54 injection molding machines range in size from 50 tons (60g shot size) to 1100 tons (5700g shot size). All machines are computer controlled. Other in-house molding capabilities include Extrusion, Vacuum Thermoforming and BMC.
