TOOLING

To complement our foundry operations, H & H operate a tooling division which produces master patterns, plastic IMP reproductions and does repair and conversions to adapt existing tooling to our FBO automatic molding machines.  All dimensional tolerances follow the guidelines set forth in the Aluminum Association standards.  We can achieve tolerances of +/-.002"/.005" on tooling yielding +/-.010 on castings in the as-cast condition using fully machined CNC iron coreboxes and aluminum match plates.
