Permanent Mold Casting
For higher volume orders we implement permanent mold tooling to combat the price per part for aluminum castings. Given a large enough production run permanent mold tooling can pay for itself and minimize lead times. As opposed to packing sand around a pattern to create the cavity for the part, a piece of iron is milled to the appropriate geometry to produce the mold. Once the mold is produced it can be indexed into a vault and pulled anytime the part needs to be run. Whenever possible multiple cavities are machined into a single mold to maximize the number of parts per pour. A single permanent mold can yield thousands of parts and can do so with great consistency. The surface finish and tolerance is comparable to that of die casting.
