We are ISO 9001:2008 Certified. We stand behind our products. If you aren’t happy, we aren’t happy. Having the best customer service available is the very core of our company.
The benefits of Investment Casting are design freedom, large alloy selection, close tolerances, better finishes, low initial tooling costs, cost savings by eliminating machining, or less machining time, reproducibility and assembly savings. Remarkable consistency is maintained with all batches.
Very intricate complex shapes that are hard to machine or fabricate make excellent Investment Casting candidates.
At The Casting Company our goal is to work with our customer as early in the design phase as possible. Our foundry engineers may be helpful in advising on weight reductions (cost), how to improve strength, alloy selection and possible design alternatives. This may also be helpful in greatly reducing tooling costs.
Size & Weight – Part size and weight are the most critical factors in determining part cost because mold capacity is limited by both size and weight. We are able to produce castings weighing from ounces up to 250LBS plus.
Number of Gates – When possible, a part should be designed so that a single gate can feed the part.
Castability – If a design contains features that will raise scrap or rework rates (and piece price), the Estimating Engineer will recommend design modifications to keep the piece price down.
Linear Tolerances – The investment casting process is capable of excellent repeatability.
Tooling – We utilize a system of tooling standards to ensure uniform high-quality design. All of our tooling is done in-house, which means we can provide a faster lead-time, avoid finger pointing, and give you our expertise in building the right tool for your needs. From concept to completion, we can help you.
Collapsible Cores – Lowest piece price, higher tooling cost.
Low Initial Tooling Costs – Initial tooling costs averaged over the parts produced are often less than other manufacturing tool costs.
Elimination of Material Waste – Investment castings are cast to size, decreasing the amount of machining required.
Design Flexibility and Capability – Infinite choice of alloys and design flexibility for internal and external configurations. Virtually any shape or configuration can be investment cast, producing internally complex parts.
Design Enhancements – There are no draft requirements in the investment casting process.
Consistency – Our process gives a reliable and consistent product from order to order.
Close Tolerances – Our typical linear tolerances can be plus or minus .005 in per inch. However, closer tolerances are frequently achieved on selected dimensions, depending on the alloy and configuration of the part.
Surface Finish Improvement – A surface finish of about 125RMS is standard for our investment castings.
Reproduction of fine details – Holes, bosses, and splines can be cast.
Reduction of production costs – Costly machining operations can often be eliminated.
Reduction of assembly and welding operations, or Conversion – Several parts can be made as a single casting, reducing assembly and handling costs.
