Investment Casting FAQs
What kinds of parts are best suited for the precision casting process? Almost any configuration can be precision cast. The key to economical use of the process is to fully utilize its flexibility and dimensional capability by incorporating as much added value into the casting as possible, thus eliminating or minimizing welding or machining to provide a part of high integrity and tighter tolerances.
What are the benefits of a precision investment casting versus other types of casting processes? Precision investment casting offers unlimited design freedom. It allows you to combine multiple manufacturing processes into one and offers a near net shape product. It also offers excellent dimensional stability, surface finish, thin sections and remarkably fine detail. Additional benefits include shorter lead-time and lower overall cost.
What is the range of size in Barron Industries produced parts? We cast a wide variety of parts, from a few inches to a 25″ cube and fabricated parts up to 65″.
What is the range of weight in Barron Industries produced parts? We pour a wide variety of parts, weighing anywhere from a few ounces to 150-pound fabrications.
What alloys does Barron Industries pour? Barron pours more than 200 different ferrous and non-ferrous alloys including:
- Carbon and Low Alloy Steels
- Stainless Steels
- Tool Steels
- Aluminum Alloys
- Other Exotic Alloys (Copper, Nickel, Cobalt)
What type of surface finish can be expected from a precision investment casting? A 125 to 150 rms microfinish is standard.
What are the “as cast” dimensional tolerances I can expect? Typically, a linear tolerance of ± .005 inch/inch is standard for investment casting. This varies depending on the size and complexity of the part. Subsequent straightening or coining procedures often enable even tighter tolerances to be held. Advance discussion and engineering considerations on the drawings can also substantially reduce or completely eliminate previous machining requirements.
How long will it take to receive a quote/proposal? Most of our clients require a quote to be returned within ten days. However, for rapid prototype services, we can turn quotes around in as little as 24 hours.
Why is Barron a one-stop shop? Imagine the efficiency of one company completing your engineering and design services and weeks later delivering complete cast and machined assemblies. This is exactly what our customers are experiencing. Barron Industries concept-to-completion process provides our customers with value-added time efficiencies and cost savings.
Where does Barron Industries deliver? Anywhere in the world.
