Milwaukee Precision Casting, Inc. specializes in both large and small castings - from intricate, miniature parts that are 1/10 of an ounce or less to large investment castings of up to 50 pounds.
Investment casting is an industrial metal forming process used to create wax models, then the models are replaced with melted metals. Firearm components, oil & gas components, medical parts, and more utilize the investment casting process.
The lost wax process is using a wax model and pouring molten metal into the mold. After, the wax model is melted and drained away.
Most metals that can be melted and poured can be used for investment casting. The most common metals are stainless steel, nickel-based steel, cobalt-based alloys, brass, bronze, and copper.
Sand and investment casting have similar processes, but sand casting cannot always make small, intricate parts. Sand casting also often utilizes heavier weight limits, sometimes greater than a ton.
Generally, investment casting has an extensive labor and cost associated with the wax molds, which cause higher costs than forged parts or sand casting.
1.What Is the Definition of Investment Casting?
Investment casting, also known as precision casting, is an industrial lost wax manufacturing process for small metal components.
2. What Kind of Products Could be Made in Investment Casting?
Investment casting process is suitable for products less than 100kg, and it is flexible for product design, no matter how complex it is. So investment casting can make almost all the small products. For larger products, sand casting is preferred.
3. What Are the Benefits of Investment Casting?

There are lots of benefits of investment casting, such as affordable tooling cost, no quantity limitation, flexible design, large selection of material specification, etc. See more about benefits of investment castings…
4. What Alloys can CFS Foundry Make for Investment Castings?
CFS foundry offers a wide range of alloys selection for investment castings. Common materials used in investment casting are :Alloy steel ,carbon steel, stainless steel, gray iron, ductile iron, etc. We can make products following your material specifications or material compositions.
5.What Type of Tooling is Required for Investment Casting?
A split aluminum tool or die is used to create a wax pattern, which is then coated with layers of stucco and ceramic material. Before pouring the alloy, wax will be first melted away, which is where the term “lost wax casting” originated. In other processes (forging, stamping, die casting), tooling is quite much more complex and expensive.
6. What General Tolerances can We Meet for An Investment Casting Part?
For lost wax investment castings, we can reach general tolerances CT7-CT8. And for smaller precision parts, CT5-CT6 can be available.
7. What Is the Typical Surface Finish of Investment Casting?
Good surface finish starts with the injection die and the production of a wax pattern with an excellent surface. Next, the first layer of ceramic applied to the pattern is designed to replicate extreme detail and create an interior mold surface that is very smooth and non-reactive when contacted by molten metal. As a result, surface finishes of Ra12.5-Ra6.3 are typical with some alloys producing smoother surfaces than others.
8. Is Small Quantity Acceptable for Investment Castings in CFS foundry?
Yes, we do not have quantity requirements for investment castings, even if a trial order with small quantity, it is also acceptable. Besides, we can supply demands of large quantity order with annual capability of 8,000t.
9. Can CFS Foundry Supply Machining Service As Well After Investment Casting?
Even if investment casting can reach excellent tolerances, but sometimes, for tighter dimensional tolerances, additional machining will be needed. So to supply finished products, we also have a mature machining production line.
10. What Is the Lead Time of Investment Castings?
Normally, it will take us about 20-30 working days for one off sample, and another 25-35 working days for batch production.
11. How Does CFS do Quality Control for Investment Casting Parts?
First of all, we have a district inner control system of each production process. Secondly,we are equipped with complete testing instruments, such as Spectrograph, Brinell & Rockwell hardness tester, Impect testing instrument, MT instrument, etc. Thirdly, sample will be provided before mass production. Also, for mass production, we will select some products randomly for testing. And even if there will be quality problem after delivery, we will also send replacements asap at our own costs or return parts of production payments to our customers directly.
12. What Makes CFS Different From Other Foundries?
CFS aims to produce top-quality investment castings with a wide range of metal alloys. Our team has the extensive experience, knowledge and commitment to ensure that you will have a truly exceptional customer experience with us. We serve online at 7×24 hours.
