Composite layup molds and bond tools

Ascent Aerospace is a world-class designer and manufacturer of composite tooling used to produce high performance composite aerospace parts and structures.

Composite tooling offers many advantages over metallic tooling.

  • Reduced weight facilitates transport through the factory and rotation on an automated fiber placement machine.
  • Lower thermal mass allows for faster, more controlled cure temperature ramp up and cool down, which drives shorter cycle times through autoclaves or ovens.
  • Prototype tools requiring a low CTE can be less expensive.
  • Rate production tools use a common master mold to produce duplicate tools and prove more cost effective than their metallic counterparts.

Since 2010, we have developed an expertise in manufacturing aerospace composite layup molds, trim and drill fixtures, and custom caul sheets at our Coast Composites facility in California. Our AS9100C-certified facility includes a dedicated 12,000ft2 (1,100m2) clean room, a 13’ x 50’ (4m x 15m) autoclave, on-site cold storage, CNC ply cutting, and laser projection – plus, our robust capacity planning and program management practices.

Our highly-trained workforce of certified layup personnel has extensive experience in a wide range of composite materials and processes, allowing us to provide the best value to the customer for any aircraft composite tooling application, from development to long-term production.
