Welcome to RLM Industries
We are Investment casting specialists. If you are machining, die casting, stamping, forging, fabricating, using permanent molds or powder metal consider investment castings. Investment casting will save your company money by decreasing production time, while increasing product quality. Investment casting is also known as "the lost wax" process, which is extremely flexible and cost effective. The investment casting process creates a near-net-shape which greatly reduces the need for secondary machining.
The Casting Difference
RLM Investment casting process offers many benefits including cost savings, design freedom, close tolerances, better finishes, savings in machining time and assembly savings.

Latest technology in automated shell building systems
It is common practice to dry shells in a large open room via conveyor system. Even with temperature and humidity controls in place, it is extremely difficult to regulate such a large area. With an inconsistent environment, the molds tend to dry at different rates and degrees depending upon where they are placed in the room. If the molds are not sufficiently dry when they are poured, surface imperfections may develop or the metal may simply run out at a weak point in the mold.
