Gronet environmental diploma, valid to 2029
The 2026 diploma recognises Alcumatic’s environmental work and declaration under Gronet’s manual; valid to 2029.
Alcumatic supplies pressure-die-cast components from Ragebøl near Sønderborg, combining casting with CNC machining, deburring, impregnation, coating and assembly. Aluminium parts and heat sinks for electronics form a core part of the range alongside zinc die-cast components. Customers can supply existing casting tools or develop new tooling with Alcumatic and external toolmakers. Powder coating, wet painting and specialist conductive coatings for plastic parts are also offered as services. The current company was formed in 1989 through the merger of Sydjysk Industrilakering and the earlier Alcumatic business, with predecessor roots in 1964.
