Due to its corrosion resistance and castability of stainless steel, many stainless steel parts are designed for industrial applications, such as marine & boat parts, food machinery components, architectural hardware, etc. For complex stainless steel components less than 60kgs, usually lost wax stainless steel investment casting process is suggested, which is simply called stainless steel casting process. If you are new to the stainless steel casting process, you should know how to effectively design your part(s) for optimal manufacturability here.

Optimizing your component design to take advantage of the stainless steel casting process is the key to seeing a return on your investment. Whether your project is best suited for stainless steel investment casting process, it&#;s best to discuss your component with an experienced stainless steel foundry like CFS. In other words, engineers should approach each project with the intent of designing for optimal manufacturability.
Design for manufacturing (DFM) is a core methodology that ensures that stainless steel cast parts perform to specification and reduce the need for secondary operations. Considering that these operations can often represent as much as 80% of the component cost, it&#;s important to minimize them during the design stage.
DFM is more than just a concept&#;it&#;s a way to remove cost and eliminate inefficiencies before your project moves towards production. In this blog, we&#;ll guide you to design your stainless steel cast component to get the most ROI.
Selection of Stainless Steel Alloys
In terms of stainless steel casting, there are various stainless steel alloys could be selected for your design, such as 303, 304/304L, 316/316L, 17-4 ph, , , etc. So, the design should understand the differences of these stainless steel alloys. For example, for food machinery application, either 304 or 316 stainless steel casting can be used, note that 316 stainless steel casting is more expensive, if you have limited budget, then you can use 304 stainless steel to cast your part. But for marine application, 316 stainless steel should be selected for its maximum corrosion resistance, in CFS Foundry, almost all the marine and boat parts are cast from 316 stainless steel. And for cookware hardwares, 17-4 ph stainless steel casting is the superior casting grade.
Reduce Weight and Wall Thickness
Before starting your design, you should have a clear concept that the weight of the part is the mainy factor to affect stainless steel casting cost. Due to the higher material cost of stainless steel alloys, the casting cost of stainless steel parts is also higher than other metal parts. So, to save cost, it is ideally to reduce the weight as possible as you can. But how to reduce weight of the part? You can consider to reduce the wall thickness while not changing the shape of the part. Keep in mind that the weight reducing should not affect the fuction of the part, otherwise it will be meaningless.
Consider Draft Angle and Tolerance
When designing your component, it&#;s important to keep in mind the achievable draft angles and tolerances for your project&#;s materials to avoid delays in redesigns. For exact tolerances, generally tolerance ISO CT5-CT6 level can be achieved for your design.
With achievable draft angles and tolerances in mind, you&#;re better equipped to avoid engineering unnecessary cost into the design. Too often, companies will request exacting tolerances and minimal draft angles while it is not practial to reach after stainless steel casting process. As a result, their castings need to be further machined for correct assembly.
So, take a more look at your design. Determine the critical dimensions of your component and mark out the tolerances required, so that the supplier can know whether post machining is needed, which will help to save cost.
In summary, if the part is new designed, remember to contact the stainless steel foundry to discuss your design for optimization. This process will make your stainless steel part more functional and cost saving.

When you start a new project, what is the first step you take?
Planning and choosing the right resources but the success of your project can also depend on having the right company to work with. When it comes to precision casting, it is important to choose the right casting companies that can meet your specific requirements and deliver superior results.
Because, in the end, the quality of precision castings done will have a direct impact on the overall performance and durability of the end product.

With numerous casting companies in the market, making the best choice can be challenging. To help you make an informed decision, we have compiled a list of six essential factors to consider when selecting a precision casting company.
Precision casting, also known as investment casting or lost-wax casting, is a manufacturing process that involves creating intricate and complex metal parts with high precision and accuracy.
It is called &#;precision&#; casting because it allows for producing components with tight tolerances and intricate designs that are difficult to achieve through other stainless steel casting methods.
When it comes to precision casting, accuracy, and efficiency are important, but speed may not be its strongest suit. So, when you&#;re searching for a precision casting company, it&#;s crucial to inquire about their project turnaround time. It is always a good idea to check their average delivery time.
A reputable precision casting company will prioritize quality, but that doesn&#;t mean you should be kept waiting indefinitely for your parts. Make sure to ask for a practical time estimate upfront when you request a quote.
Look for casting companies that have a proven track record in the industry. Consider their years of operation, the types of industries they have served, and the complexity of projects they have successfully handled. An experienced precision casting company will have the necessary knowledge and skills to understand your requirements, provide valuable insights, and deliver high-quality results.
Precision casting is a complex process that requires in-depth knowledge and expertise. From creating and refining the cast to managing the heating and solidification process, as well as removing the cast and ensuring there are no bubbles, each step demands experience and skill.
Most companies display their certifications on their websites. Certifications like ASME, Nadcap, or PEDs, depending on the specific requirements of your machine. However, it is important to note that while some companies may outsource the testing process, it is preferable to select a company that can conduct its own tests on-site. This saves both parties time, money, and unnecessary hassle.
When choosing a precision casting company, consider your overall needs. If you require more than just parts, look for a company that can offer additional services. For example, if you lack knowledge in metallurgy, find a company that can provide guidance on the right alloy for your needs.
Some companies specialize in specific metals, but if you need parts in different materials, it&#;s best to find a company that can cover all your requirements. This will save you time and money in the long run.
