Hot Press Process
For high-volume, geometrically simple components
The hot press process is used for geometrically flat components with a high degree of reproducibility and surface quality.
Strengths of the hot press process:
- reproducible fiber deposit
- high fiber content
- high surface quality
- polydimensional shaping, precise geometry
- high temperature resistance
- short cycle times
In the hot press process, prepregs are hardened in a press mold. They are then cut to size on the cutter and laid into a mold layer by layer (pre-laminated) in the desired sequence and alignment - until the desired layer structure is achieved. The filled mold is then locked into a heated press. A counterplate or a plunger made of elastomers can be used as a plunger. Similar to deep drawing, the material can move when there are complex curved surfaces - we take this problem into account already in the design phase. Depending on the material and product, hardening can take anything from a few minutes to 2 hours. The component is then removed from the mold and processed further.
CONNOVA has the right expertise and resources for the hot press process:
- controlled high temperature presses
- high-quality, temperature-resistant molds
- CNC cutting room for precise and efficient cutting to size
- controlled freezing units for secure storage of unhardened prepregs
The hot press process is used
- in aviation: lining parts, interior finishing
- in car building: decorative and cowling parts, screens
- in mechanical engineering: fittings, covers, fast-moving machine parts
- in medical engineering: prosthetics (walking aids outside the body)
- for sports equipment: skis, bats
