Lamination
Maximum durability and design freedom.
In a world in which innovation cycles are becoming ever shorter and product developments increasingly complex, the selection of suitable manufacturing processes is gaining in importance - especially in prototype construction. Laminating is one of these processes, which is characterized by a high degree of design freedom, stability and lightweight construction potential.
MODELLTECHNIK create customized solutions for a wide range of industries. Thanks to many years of experience, state-of-the-artmachinery and precise manual work, ModellTechnik produces fiber-reinforced components that set standards in terms of quality and function.

Lightweight construction meets precision
For companies that want to implement complex components with functional and aesthetic requirements, lamination offers a convincing solution - especially when additive or conventional processes such as injection molding reach their limits. Laminating is a flexible approach that efficiently combines design and technical requirements, especially for one-offs and small series.
GRP
Glass fiber reinforced plastic
GRP is the most widely used composite material in the lamination process. It consists of glass fiber mats or fabrics that are impregnated with a resin system (usually epoxy or polyester resin) and then cured. GRP offers a goodstrength-to-weight ratio, is inexpensive and relatively easy to process.
Good mechanical strength
High chemical resistance
Electrically insulating
Less expensive than CFRP
Slightly higher density than CFRP, therefore heavier

CFRP
carbon fiber reinforced plastic
CFRP is the premium solution in the field of fiber composites. The use of carbon fibers creates an extremely rigid, but at the same time very light compositematerial. CFRP isusedwherever maximum performancewithminimumweightisrequired.
Outstanding rigidity and strength
Very low weight
Very low thermal expansion
Electrically conductive
Higher material and processing costs

Resin Infusion Process
Vacuum infusion
Vacuum infusion, also known as the Resin Infusion Process or VARTM (Vacuum Assisted Resin Transfer Molding), is a modern manufacturing method for producing lightweight yet highly durable fiber-reinforced composite parts made of fiberglass or carbon fiber. In this process, dry fiber layers are placed into a mold, sealed airtight with a vacuum bag, and then infused with low-viscosity resin under vacuum pressure. The controlled resin flow ensures parts with a very high fiber content, low porosity, and excellent mechanical properties.
This method offers efficiency, dimensional accuracy, and environmental benefits, as the closed process significantly reduces emissions. Typical applications include boat building, wind energy, automotive and aerospace industries, as well as prototype manufacturing, where maximum quality and weight reduction are essential.
