Multiple E-glass layers are lamimated by hand using high quality epoxy resin

Composite technology

Knierim Tooling builds moulds from GRP and CFRP by a hand laying technique or with vacuum infusion and prepreg technology. These methods ensure the optimized ratio of resin and fiber for minimum weight at maximum stiffness. Carbon or glass fiber sandwich technologies are used according to the requirements regarding durability and performance.

Knierim uses epoxy resin as well as sandwich materials and cores by known producers all tried and tested in boat building. Curing times can be precisely controlled either with heating pads or in an oven to ensure an even cure and high quality.

As most moulds are built with vacuum technology, vacuum tightness is an important feature. Knierim offers a vacuum testing system for its master plugs if required.  During this test Knierim’s products may show a maximum drop in vacuum of less than 10 hPA/h.

Knierim Tooling GmbH is certificated with a Workshop Approval of Germanischer Lloyd and Lloyd’s Register.
