...and more. Our CoolFlow technology (flushing with -30°C cold nitrogen) is one of our key technologies for reducing warpage tendencies and especially cycle times. In addition, temperature control techniques can address specific issues in plastic injection molding, such as alternating temperature control with steam or induction to avoid weld lines or poor surface quality. CO2 temperature control...

... hardening takes place at H+W in multi-purpose chamber furnaces. Carbonitriding: "Carbonitriding" refers to the enrichment of the surface layer of a workpiece with carbon and nitrogen followed by hardening. This process is preferably used for automatic and construction steels that do not achieve sufficient surface hardness during case hardening. At H+W, this occurs in a carbon-rich atmosphere at high temperatures with the addition of ammonia (NH3).
