7、Does the oxide layer adhere differently between blasting and polishing after anodizing?
These two finishes adhere the same to the oxide layer.
8、If color is not consistent between same color parts, is it nonconformance?
Typically an inconsistent color within the same part it is an inconsistent surface pretreatment that is magnified after the anodize process.
Just like machining, there is always tolerance for measurements. Color also has its high and low range, and it is acceptable if the color is in the range. Danco technology’s makes the tightest color range.
Danco can provide a color range board, which can be used by customers to perform inspection.
Typically, the titanium pieces are provided by customers and anodized at no-charge. Customers can then place the samples in a controlled assembly, free from dirt and dust.
9、Why can’t we process assembled parts?
There is a risk of trapping chemicals in the areas of the assembled part which cannot be thoroughly rinse out. These chemicals may leak out during packing, transfer and shipping, which could cause harm to operators and final implant customers. This is why parts must come to Danco unassembled.
