Open Mold Hand Lay-up:

is an open-molding composites fabrication process where reinforcements are cut and hand laid onto a reusable mold. Catalyzed Resin is then applied, saturating the reinforcements. Workers roll out the resin and reinforcement to compact the laminate. Wood, foam, or other core material may then be added, and a secondary layer imbeds the core between the laminates. The part is then cured, cooled, and removed from the mold.

Advantages

• Lower cost of the raw material by using glass mat.
• No gap in the molding products, satisfactory integrity.
• Free adjustment of wall thickness of the product, the proportion of fiber and resin as well as the length of fiber.
• Lower tooling cost suitable for one off & low volume production.
