10 Advantages of Investment Casting

There are many advantages to investment casting which will lead to better design and a lower cost product.

The investment casting process offers many benefits including cost savings, design and material freedom, close tolerances, better finishes, savings in machining time, reproducibility, and overall – they just look better!  Read about the 10 advantages of investment casting.

Investment Cast Stainless Steel Pinchers for the Food Industry


1. Superior Surface Finish

The investment casting process provides far superior surface finish as compared to forgings and sand castings. This can be important at times to avoid machining or other finishing operations.

 

2. Variety of Materials

Investment cast parts can be cast in a range of alloys including stainless steel, brass, bronze, cobalt, nickel and custom alloys. Franklin Bronze casts non-ferrous alloys for many applications in a broad range of industries.

 

3. Closer to Finished Part Designs

Investment castings provide near net shapes for manufactured parts, thus eliminating or reducing machining costs. An added benefit of near net shape is the savings on material, especially with more expensive alloys like nickel and cobalt alloys.

 

4. Intricate Design

Holes, undercuts, slots and other difficult detail that cannot be had with other processes can often be provided through investment casting – thus reducing the amount of machining.  Logos, numbers or names can be incorporated on parts as markings.

 

5. Difficult Thin Wall Castings

The investment casting process is capable of more reliable castings with much thinner walls than sand castings. Advantages include substantially less scrap rates and castings that weigh less due to the thinner wall capability.

 

6. Tight Tolerances

Due to the nature of the process, investment castings can be held to much tighter tolerances than sand castings or forgings. Tolerances down to + – 0.1mm can be achieved – resulting in a highly accurate cast part.

 

7. Competitive Tooling Costs

With Franklin Bronzes’ own in-house tool manufacturing, initial charges for the investment casting tooling are often less expensive than those for die castings and forgings.

 

8. Minimal Casting Defects

Being a cleaner process than sand moulds, investment castings in general, provide a much higher percentage of defect free-castings.

 

9. Rapid Prototyping for New Product Development

Rapid prototyping can get products to market faster.  Franklin Bronze uses 3-D Wax Modeling for efficiency and speed in design and production.  Using 3-D Modeling, FBPC can move faster from the development phase to the production phase.  3-D Modeling can be especially beneficial for those with requiring quick, small order prototyping as there is no need for wax model tooling.  This speed to market helps customers compete in the marketplace.

 

10. And…they just look better!

Whether or not appearance is critical, investment castings have the appearance of high quality. Minimal to no discernible parting lines are the norm. Also, most outside surfaces do not require draft.
