A casting of silicone, polyurethane or epoxide resins ensures the functionality and long lifespan of components even in environments with extreme temperature differences, high humidity or high chemical stress. The casting moulds are made in EPSa’s in-house pre-production department. For higher demands, we also offer vacuum casting (≤ 1 mbar) in a double-chamber system with a mixing head. It prevents bubble formation in casting and strengthens qualities such as high-voltage strength.
