Working with Eagle Alloy
Whether you’re improving an existing part or bringing a new product to market, metal casting can be a great choice. No matter why you’re interested in buying cast parts, Eagle Alloy welcomes your business.
When you work with Eagle Alloy, your first point of contact will be with a representative of our sales department, who will help you determine the optimal materials and processes for your product. Next, you’ll interact with our engineering team to further develop your design. With knowledge, experience and the latest tools at our disposal, we can save you time and money by preventing future issues early in the design stage. Once your design is ready, we’ll get started on what we do best: manufacturing quality cast parts. We’ll handle tooling, prototyping, manufacturing, finishing and quality control. Once Eagle Alloy goes to work, you can relax and get ready for your first batch to arrive.
Determining Your Needs
Before you start collecting quotes for buying cast parts, here are some key questions you should ask yourself:
- What material is the part to be made of?
- What are the projected order quantities and annual quantities?
- What is the desired surface finish?
- What tolerance range is necessary?
- Is there significant machining required to the finished part?
- Initial tooling costs differ greatly from one casting process to another. Which is more important to the project: tooling price or casting price?
Knowing the answers to these questions will help guide you toward the optimum casting method and help you avoid over-spending.
