Frequently Asked Questions

What is the film thickness for 3C aluminum phone cases?

8-12 μm is typical for Type II sulfuric acid anodizing in this configuration.

Can fine sandblasting and dyeing be combined?

Yes. Fine sandblasting, such as 120#-320# glass sand, and organic dyeing can be integrated.

Is color difference controlled?

A color difference target of ΔE ≤ 0.5 can be agreed based on sample and measurement method.

Can the line run semi-automatically?

Yes. Semi-automatic and manual operation are available, with optional automation.

Is electrophoresis available?

Yes. Optional electrophoresis power DC 0-200 V, 1-3 kA, with paint rectification, recovery and curing oven can be integrated.

What quality tests can be specified?

96 h neutral salt spray, RoHS/REACH and hexavalent chromium-free sealing can be specified according to project requirements.
