CFC workpiece fixtures for high-temperature processes.

Durable, lightweight and efficient charging racks and batch carriers



In industrial high-temperature processes, our workpiece carriers made of graphite and carbon fiber composites impress with their outstanding technical properties. Benefit from our many years of market knowledge, our comprehensive materials expertise and our leading manufacturing technologies to achieve the best results. Schunk is your fully integrated manufacturer and technology partner when it comes to optimizing your high-temperature processes in terms of safety, cost and time.

Workpiece carriers that meet the most stringent requirements

Our charging racks and batch fixtures for heat treatment still reliably provide top performance in the high-temperature range even when steel and other metals reach their limits. For example, metallic racks can often warp and deform due to the heat input. This in turn results in higher scrap, as the deformation of the metallic racks also affects the parts to be treated. Automation is also made more difficult or even impossible by the deformations, as robots require fixed positions. In addition, the service life of metal is shorter compared to our CFC materials due to embrittlement, whereas the mass and associated energy requirements are much higher.




Whether complete racks or even just grids for heat treatment - everything with added value

No matter which of our products you choose, you can always count on added value that pays off. For example, our solutions are dimensionally stable and resistant to distortion, slim in design and light in weight. They are economically convincing thanks to a long service life and a reduction in the proportion of rejects. They increase the energy efficiency of your processes due to a very low thermal mass - the energy used is for heating and cooling the parts to be treated, not for the workpiece fixtures. Last but not least, your productivity is increased because process times can be shortened and processes automated.

We attend you from the initial idea to the introduction of a customized batch carrier system into ongoing series production. In doing so, we can offer you solutions that are completely adapted to your requirements in terms of material, surface treatment and degree of individualization. Choose from the following concepts:

From standardized to individual

according to your requirements
  • Square and round water-jet cut grids - ideal for low to medium weight loads.
  • Square and round interlocked grids - especially for high weight loads with minimal deflection
  • UniGrid® - our modular batch fixture system with integrally manufactured grids consists of a continuous fiber structure and has no joints
  • Systems made of CFC and graphite - suitable for one or more levels
  • Systems with carburization protection (ceramic or Durafox®)
  • All-oxide racks - innovative materials that resist thermomechanical stress in highly corrosive or oxidizing atmospheres

We document the status quo, record your wishes and clarify the framework conditions - gladly on site with you.

 Icon Design Proposal from Schunk Carbon Technology

The information obtained and your wishes form the basis of our design. We check this together with you and then produce an FEM calculation (finite element method).

 Icon conclusion of negotiations from Schunk Carbon Technology

The design is approved by you. We make you an offer and you place the order for production.

  Icon Manufacturing from Schunk Carbon Technology

Your workpiece carriers are produced with our own materials - this enables us to provide consistent quality assurance.

 Icon shipment of the products from Schunk Carbon Technology

Together with your product you will receive a SPEC (Specification for Carbon Fixtures). This contains all relevant information, e.g. form and function, FEM calculations, technical facts, explanations of loading situations, information on handling and much more.
