The inner surface of the hole can be polished without chemicals.
We can polish the inner surfaces of complex cooling circuit holes processed with 3D modeling. By performing polishing, surface roughness is improved, leading to increased flow rates. Additionally, rust and scale removal is also possible (after maintenance). Our company’s characteristic is that we can polish without chemicals and with minimal distortion of the shape.

Company information
We mainly manufacture core pins, inserts, sprue cores, and sprue bushes for die casting. Since February 2019, we have started producing inserts with complex cooling structures using metal 3D printers (maraging steel, improved SKD61 steel), and in May 2024, we introduced a fluid polishing machine. Additionally, we are confident in our hole processing capabilities, being able to process holes as small as φ1.5 to a depth of 280mm, and φ2 holes to a depth of 440mm (for both through holes and blind holes). Since our production is primarily made to order, we can accommodate requests starting from one piece. In addition to hot work tool steel commonly used in die casting, we also have processing experience with materials such as cold work tool steel, high-speed tool steel, and stainless steel (SUS303, SUS304, SUS310, SUS630), so customers from fields other than die casting are also welcome to inquire.
