Ready to Start Resin Infusion.
Resin Infusion is a specialized advanced composite laminating technique that greatly improves the quality and strength of fiberglass parts versus conventional hand lay-up or spray-up methods.
In the recent years, both polyester and vinyl ester resins, materials, supplies, and processes used for the resin infusion process have improved significantly thus making it commercially feasible for a wide range of products.
Any composite or fiberglass part that is made using the open mold process can be resin infused.
Resin infusion process utilizes vacuum to drive resin into a laminate. Applying laminate engineering and resin infusion technology simultaneously allows for optimization of a part in terms of strength and weight.
The use of resin infusion is becoming a standard for boat hulls, yacht construction, wind turbine blades, bus parts and pre-engineered modular roofing where RTM or hot press methods are not applicable due to size constraints.
Also resin infusion is a cost effective solution for prototyping and small productions by eliminating expensive mold requirements.
For many applications, parts manufactured using the resin vacuum infusion process have higher quality, better consistency, higher glass content, higher specific strength, higher specific stiffness, better interior finish, faster cycle time and lower cost compared to the open mold process.
Higher quality laminates. The process is independent on the skill of the user.
Consistent part quality after a successful process design.
Composite quality and process control will be optimized compared to the open mold process.
There will not be any entrapped air; the laminate will be perfectly consolidated and the wall thickness will be consistent.
Minimal part shrinkage and distortion.
Better fiber-to-resin ratio. Infused laminates will have glass content by weight ranging from 35% to 50% compared with 25% to 35% for chopper gun laminated parts.
Both hand lay-up and spray-up methods usually result in excess of resin which reduces mechanical propetries.
The parts will have higher specific strength and specific stiffness.
Complex parts with ribs, core, and brackets can be made all together in one step eliminating secondary bonding operations.
The part can be made net size thus reducing post-finishing time.
The non-molded side of the part can have a good finish if an inner mold is used.
Faster cycle time. Cycle times of 2-3 hours are typical so a mold can be turned 3-4 times per shift.
Environmentally friendly, no air pollution from volatile organic compounds

Econolease Peel Ply
Release fabric
1,52mt x 91,4mt (5,9 kg)
A tight weave nylon peel ply coated with a silicone release agent for easy removal and a "fine" textured surface.
Econolease is a silicone treated nylon peel ply which provides greater release in difficult environments.
Our Econo peel plies are designed to work in resin infusion or hand lay-up processes. All coated peel plies have the potential to transfer.

Econoply E
Non-coated, heavy duty polyester peel ply
1,524mt x 228,6mt
Econoply E is a heavy weight polyester peel ply developed for use in difficult environments and where a more textured surface is required for secondary bonding.
Maximum use temperature 149 C.

Bleeder Lease® B
Coated nylon peel ply
1,524mt x 100mt
Bleeder Lease® B peel ply is a high temperature fabric coated with a silicone release agent.
Bleeder Lease® B provides superior release to plain peel plies because the coating prevents the heated fabric from fusing to the laminate while producing a textured surface.
Bleeder Lease B will provide easy release from most prepregs and resin systems. All coated peel plies have the potential to transfer. Bleeder Lease® B is a tightly woven, coated nylon peel ply that releases well from most resin systems. It is excellent for many resin infusion projects.
