Xenom has a broad experience in the design, engineering, development and validation of materials and manufacturing procedures. We are processing RTM & resin Infusion materials using out of autoclave techniques (OOA), hybrid technologies and all standard manufacturing techniques for composite materials.

A pigmented gel coat is first sprayed onto the mould for a high-quality surface. When the gel coat has cured, glass reinforcing mats and woven rovings are placed on the mold, and the catalyzed resin is poured, brushed or sprayed. Manual rolling then removes entrapped air, compacts the composite, and thoroughly wets the reinforcement withthe resin. Reinforcements and accessories are affixed depending on the functionality of the final product. A catalyst or accelerator initiates curing in the resin system, which hardens the composite without external heat.

A closed mold system technique that uses vacuum & external pressure to drive resin through a laminate. Reinforcing fabrics is placed on the mold, and the catalyzed resin is injected. The mold is closed with a female mold, external pressure is applied to push the resin through the laminate and curing takes place; hardening the composite mostly with external heat.

VIP is a technique that uses vacuum pressure to drive resin into the laminate. Materials are laid dry into the mold, and vacuum is applied before the resin is introduced. Once complete vacuum is achieved, the resin is sucked into the laminate via carefully placed tubing.

The process starts with pattern making, designed in a 3D software. The typical model is based on a machined EPS core, laminated with epoxy/glass fibers, covered with epoxy tooling paste and re-machined. The model is used to prepare the mold, as a cavity into which reinforcement fabrics and resins are laid. Often, molds are repeatedly cast from the model to produce male and female versions until the desired strength and finish quality are achieved.
