Multilayer pressing tools
PrintThe tool for high-quality products
High pressure as well as temperatures up to 400° C require precise standards for top- and bottom plates of tooling. The grades BBM N702 and BBM Cr50 were specially selected for this purpose to achieve a permanent precision and stability against distortion and thermal shock stresses. Special advanced technology guarantees consistent high dimensional stability, optimum flatness and parallelism. Precisely positioned hardened bushings, standard round or sparked, slotted registration holes with the tightest tolerances available ensures an optimal manufacturing process.
Used pressing tools are refurbished professionally by us in short terms.
