Bore gold plating
Bore polishing/Surface treatment
Bore polishing for small diameter tubes is available (the minimum inner diameter can be 0.1 mm.) We have accomplished minimum surface roughness, maximum circularity, and minimum contamination required for medical and analytical instruments.
We can provide various kinds of surface treatments to meet your requirements, for example:
Teflon ® coating, which is water/oil repellant and insulating;
transparent F2901 coating less than 1um thickness;
gold plating, which is inert, and corrosion and abrasion free
