Methods d’application
The so-called molding application method CONTACT is a completely manual technique.
It requires the use of a mold on which glass fiber reinforcements are placed. These are impregnated polyester resin using a roller, d’un pinceau ou d’une machine.
After the resin has hardened, the part is removed from the mold and cut out.
This laminate then has a smooth side (the Gel Coat side) and a raw side (the fiber side). Advantages :
- Very wide possibility of shapes and sizes
- Low investments
- Simple and inexpensive molds
LORN Products Affected:
Advantages Simultaneous projection molding is commonly used to fabricate large parts.
It involves simultaneously projecting the pre-accelerated polyester resin and the cut fiber using a gun.
Possibility of manufacturing large parts Low cost of molding
LORN Products Affected:
This process consists of pouring resin into an open or closed mold.
This technique makes it possible to produce pieces of heavy and medium thickness (eg. Bathroom sinks)
Advantages :
The final result is smooth and weathered.
The shapes and dimensions are according to your project.

The method of molding application by FILAMENTARY WINDINGS is automated and intended for complex parts (tube, cone, tank, silo, etc.).
The principle is to wind fibers impregnated with resins around a mandrel acting as an interior mold.
