Machining of castings | Support for other companies' cast products, with experience in processing semiconductor components.
AC4A-F
We cannot find a machining partner for castings produced by other companies. For semiconductor parts, we accept machining only from raw materials and provide consistent support up to inspection.
Have you ever struggled to find a machining partner for castings produced by other companies? For rough materials that require high precision, such as parts for semiconductor manufacturing equipment, there are limited machining partners that can handle only the downstream processes. Casting manufacturers often prioritize finishing their own cast products, making it difficult to process castings produced by others due to precision assurance issues, leading to procurement challenges. The uncertainty regarding material properties and shrinkage of rough materials also complicates the estimation of machining conditions. Karmo Casting owns machining equipment, including 15 five-axis machining centers, and can accept rough materials from other companies for machining after confirming their material and shape. Since we also conduct our own casting, we can accommodate the estimation of machining conditions considering the shrinkage and distortion of rough materials. This product is an example of parts for semiconductor manufacturing equipment that have been consistently finished from machining to inspection using rough materials cast by other companies. We are offering a technical document summarizing the break-even points by method and considerations for small lot production free of charge. Please download it from the link below.

Price information
If you provide us with the drawings and the casting (actual item), we will give you a free estimate. We also accept machining of cast products from other companies, regardless of material or casting method. Since we can handle everything from our own casting to machining, we can also suggest options if you need to remake the casting.
