Preform Molding

Used in the Composite Industry for over Sixty Years

Like compression molding, preform molding creates parts with excellent mechanical and structural properties. The difference between the two processes is flexibility. Preform molded parts are manufactured with a uniform distribution of glass fibers and strategic placement of glass reinforcements that increase durability and flexibility in high-stress areas. Preforms are used in a variety of structural component applications regardless of volume.
