Depending on requirements, Keller & Kalmbach offers basic parts or parts with demanding contours, as well as punched, drawn, or pressed parts. Whether steel, stainless steel, spring steel, bronze, copper, brass, or plastic - everything can be created in technically feasible strengths. Combined punched, pressed, and embossed parts can also be supplied. Water jet-cut and laser-cut parts can also be offered in smaller quantities.
Cold-formed parts and special screws are produced on multi-stage presses from formable steels and non-ferrous metals in all standard strength classes, including subsequent machining. Warm-formed parts are offered in complex shapes using corrosion-resistant, heat-resistant, creep-resistant steels and alloys. In addition to this, we offer basic subassemblies for these parts (e.g. O-ring installation).
Keller & Kalmbach offers plastic parts based on customer requirements, taking into account the latest production technologies. Thermoplastics and thermosets are processed for virtually all areas of application using an injection molding process. Complicated shapes and parts produced in small quantities are turned or milled.
