Temperature control of the processing solution is possible! Processing can be done regardless of shape, from one piece to large lots.
"Passivation treatment," also known as passivation processing, involves immersing the product in a treatment solution to form a passive film on the surface of the product. This process allows stainless steel products to be protected from corrosion for a long time, adding value to the products and enabling them to maintain their beauty without rusting. Since it is colorless and transparent, and there are no changes in appearance or dimensions after treatment, it can also be applied after designing the base surface. [Features] - Fine adjustments can be made to meet customer needs - Can be processed in conjunction with electropolishing - Can be processed regardless of shape, from one piece to large lots - Careful handling of cleaning and packaging tasks *For more details, please refer to the PDF document or feel free to contact us.
