※This information is based on reference data from our company’s production lines.
Please notify/consult us about the following when placing an order for Kashima Coat treatment.
(a) Material properties (b) Film thickness (c) Hardness (d) Surface roughness (e) Position of electrode (f) Presence of masking and (g) Other precautions.
The target value of film thickness tolerance is ±20%.
【E.g. Film thickness: 10 ± 2 μm】Separate consultation is required as the film thickness tolerance differs with cast metal and die-cast materials. Please consult us regarding the amount of dimensional changes.
The color tone of Kashima Coat treatment differs greatly depending on the materials used, film thickness and coating conditions.
Please consult us if color tone control is required. A sample product will be created and controlled, displaying the color limits.
Please note that any cutting lubricant or buff polishing dust from machining remaining on the supplied parts may affect the quality of the finished appearance.
The anodizing film may not adhere properly due to the machining methods used with some materials
(ｗire cutting, electrical discharge machining, etc.)
Inclusion of Dissimilar Metals
Will dissolve during treatment, so must be removed. Please enquire about the possibility of a masking based solution.
