Heat treatment and surface finishing
What zinc plating and salt spray performance is available?
Answer
What is high salt-spray zinc plating? + Zinc plating is judged by how long the plated part survives neutral salt spray before white or red rust appears. A high salt-spray specification means the coating thickness, the passivation type and any post-treatment are chosen to reach a longer test duration than a standard commercial finish. The hours are agreed against the drawing —

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Need a DFM feasibility assessment for your project?
Send the engineering drawing (STEP or PDF) with the material grade, thickness and annual volume. Balford engineers then check it against the process window - draw ratio, wall thickness, tolerances, blank and tooling route - and come back with what is feasible and what is not. An answer on this page cannot replace that review.
