The pre-cut of the glass-fibre mats is carried out after the “AD Merkblatt Nr. 1/1983” and is based on the calculation of the needed wall thickness.

The glass-fibre mats are laid into the moulds after layout plan, are soaked with resin and get rolled out with hand pressure.
The treatment by hand guaranties an optimal quality.

After the curing process the shell is demoulded und simultaneously undergoes a optical quality inspection. Shells damaged on critical spots (e.g. sealing surface of the O-rings) are disposed immediately.



Since our products are handmade, small deviations are not avoidable.
