We all know that obtaining stainless steel investment castings is the best way to go when you’re planning to produce high-quality and affordable parts that are well-suited for sensitive applications. However, when you’re still trying to determine the need for custom-made stainless-steel parts created by the investment casting process, it’s important to consider the factors that affect its turnaround times and costs. If you want to set your project up for success, you’ll want to be aware of these details ahead of time.
You can maximize the production of stainless steel investment castings while minimizing costs when you include details such as the draft (tapers on the vertical faces of patterns that removes patterns from molds without damaging its walls), the minimum section thickness (determined by the desired rigidity and strength and should be at least 3mm thick), the cores (the hollow spaces within the investment castings), and the parting line (facilitates the creation of patterns and molds).
Wax patterns are used to create molds or investments. It’s critical to establish clear requirements about the pattern equipment design and production so that you’ll have a clear idea of the costs and misunderstandings will be avoided.
This group of requirements that serve to meet metallurgical standards was outlined by the American Society for Testing and Materials (ATSM International). Following these specifications will misunderstandings, higher costs, and exclusion of potential foundries.
