    Thick plating support

    ※This photo is a sample.

    Is it possible to tread the inner diameter of a large product with a plating film thickness of 0.25mm and finish the shape by grinding?
    Research and vender selection
    We selected a company that can handle large hard Cr plating and has a vertical internal/external diameter grinding machine, and investigated its facility capacity.
    Since this was a large item, we selected a company that was capable of handling the work and with whom we could easily collaborate.
    Three companies, including our company, discussed the method of construction, order of construction, transportation, etc., and manufactured a prototype to confirm and evaluate the method and order of construction, making repeated fine adjustments.
    After the product was completed, we visited the client company to check the film thickness, shape,appearance, etc., and determined that the product was satisfactory, so we delivered it.
    The customer commented, ” Customer was very helpful because there was no company that could handle thick plating and shape processing. The customer thanked us for our service.

    Specialty proposals

    Leave a message
    Soak a stainless steel product (SUS316L) in seawater or an existing waterway for a long period of time, any suggestions?
    Research and vender selection
    Although SUS316L has excellent corrosion resistance among stainless steels, we were asked to make a proposal because we reported that, depending on the operating environment, scratched and other defects may destroy part of the passivation film due to the chlorine component, resulting in localized corrosion.
    We suggested changing the material to titanium, which has excellent corrosion resistance, but the response was that this was not possible due to the high cost of the material.
    Therefore, we proposed a passivation treatment (passivate treatment) that can reinforce the oxide film on the surface of stainless steel materials (chromium)
    In addition, due to the rising cost of stainless steel materials, we proposed a partial revision of the shape of the drawings that would significantly reduce material costs, as well as reduce weight and prevent scratched, both of which were adopted.
    In this project, we proposed quality and cost-conscious proposals, such as surface treatment on stainless steak products and material cost reduction, without changing to titanium material. We would like to receive further cost reduction proposals in the future.
