- Two or more structures can be molded as one casting thereby reducing assembly cost.
Q: Should I cast or machine an aluminum
A; There are very few instances where machining or hogging out a part from aluminum stock is cost effective. We cast near net shape parts at a fraction of the cost of a machined part. If machining is needed, it is generally to perform finishing touches such as threading or facing of a surface.
Q: What makes Pentz castings so unique?
A. Pentz has earned a reputation for providing the finest "as cast" surface, highest structural integrity, vacuum- and pressure-proof and closest tolerances in the industry. Pentz products far exceed industry, government and military specifications.
Q: Why do Pentz castings have a superior
"as cast" surface finish?
A: It has been said that you can give a person paper and pencil but it does not make them an artist. This analogy holds true for building castings: Pentz' ability to consistently produce high quality "as cast" surface finishes has been developed over many years and millions of parts. Our "as cast" surface finish far exceeds the RMS of all standard industry specifications.
Q: What casting process should I use?
A: We have several processes available including precision green sand, precision dry sand and permanent mold. There are a number of factors to consider when selecting a process, including the type of alloy to be molded, dimensional tolerance requirements, structural requirements, machining and post-machining operations. Our team of process experts will assist you in selecting the right process based on your part requirements. See our Molding Process Comparison Table.
