Resin Transfer Moulding (RTM)
Resin Transfer Moulding (RTM)

Resin Transfer Moulding is a resin injection process. Rotec is using vinylester and epoxy resins  with fiberglass reinforcement in various forms such as:veil, continuous mat and various combinations of mat and fabrics. By RTM technology Rotec manufactures high quality products with high strength-to-weight ratios and precise constant dimensions.

Compression Moulding
Compression Moulding

Compression Moulding is a high-volume production technology, allowing processing Sheet Moulding Compound in large numbers of composite products. SMC is a pre-impregnated composite sheet made by resin, chopped fiberglass, fillers and additives . Compression Moulding requires expensive but very durable steel moulds and is used by Rotec to produce Backing Rings (Loose Flanges) in diameters DN 25 – DN 300 mm.

Vacuum Infusion Process (VIP)
Vacuum Infusion Process (VIP)

Also Vacuum Infusion is a closed mold process. Atmospheric pressure is used to push the resin into the mold cavity.  The process is highly controllable and results in very consistent product quality. Another advantage (like for all closed mold production technologies) is a minimal styrene emission.
