Our products and solutions

Our innovative resin transfer moulding (RTM) and infusion technologies are redefining the boundaries of composite part manufacturing. These two related technologies are used in a wide variety of applications ranging from components of watches and other luxury goods to medical parts and aerospace components. RTM allows the creation of complex components in highly accurate dimensions with smooth surfaces and excellent surface detail. Composites Busch employs this closed mould technology for components ranging in size from a few centimetres to larger elements up to approximately two square metres. Wall thickness ranges from about 0.5 mm to 30 mm.

Infusion moulding is an open moulding technology especially suitable for components in which only one side must have a perfect appearance.

CNC machining is a widely used technology found in numerous industries and applied to composites as well as a variety of other materials. Due to the presence of fibres in composite material, machining composites demands a high degree of expertise and experience. Composites Busch CNC machining capabilities are based on our many years of experience working with composite materials to manufacture high-precision parts for watchmaking and the medical devices industry. Composites Busch has eight CNC centres with five axis machining capabilities.

Our teams of engineers and specialists are all experts in the field of innovative composite solutions perfectly manufactured to meet design, material, performance and market demands. Because each customer’s requirements are individual, each project is supported by one dedicated team that manages all project stages – from the initial design concept and development through to prototyping and industrialisation. Close relationships with our customers bring the benefits of greater cost-effectiveness and high responsiveness to individual demands, while guaranteeing optimum performance, reliability and creativity in the finished product.

Additive manufacturing is a cost-effective and extremely flexible production process in which, assisted by 3D CAD data, a part is manufactured by repeatedly adding layers of material to a “building platform”. Laser is applied to the layers on the platform and the process repeated until the part has reached the dimensions and form defined by the 3D CAD data. The process is suited to rapid prototyping as well as serial production. Additive manufacturing with composites is a technology that offers a very high degree of freedom in form, as well as surface and form complexity, while bringing the benefits of light-weight parts that can be manufactured with little material waste.
