Investment casting according to the lost wax method is a very old casting process, having been used in ancient Egypt for the production of art and cult objects.

Today this production method is gaining popularity. Through the use of high temperature resistant molding material binders, this method has many advantages in comparison with other casting methods.

Design latitude – Creative design improves function, saves expenses and gives a sophisticated appearance to the final product. The investment casting method offers this liberty, because undercuts, thin wall-thickness or three-dimensionally shaped areas can be produced with this casting technology. Vast variety of materials – All steel and stainless-steel materials as well as aluminum alloys, brass and bronze can be cast, very close to the final shape, by means of the highly refractory ceramic shell.

Close tolerances and high quality surfaces – In many cases parts can be manufactured ready for installation. This saves machining costs. Draft angles are usually not necessary.
