Companies who need mechanical finishing services and zinc phosphating can lower their total costs, improve scheduling and lower transportation expenses with RTF’s state-of-the-art zinc phosphating line, which was commissioned in 2005. The line was engineered for greatest uniformity of deposition, highest batch-to-batch repeatability and maximum traceability in meeting customer needs.
The line applies lfine or heavy zinc phosphating,
and there's a separate additive tank for imparting a black
finish. The heavy zinc phosphating process (2000 mg/ft.2)
is used primarily for automotive, off-highway, machinery
and other heavy-service components. For parts that will
subsequently be bonded, painted or powder coated, RTF applies
a calcium-modified zinc phosphating that deposits a
microcrystalline base.
There are various topcoat options on the RTF zinc
phosphating line: a water-displacing oil that produces
maximum long-term corrosion protection, a water-
displacing oil that is dry-to-the-touch, a water-soluble
oil and a water-based rust inhibitor.
RTF’s zinc phosphating system runs standard process cycles, and custom process cycles that are created to meet customer specifications. Chemical analysis and process control are automated to satisfy various quality programs. With each completed load, the zinc phosphating line generates a process summary detailing the process cycle, the tank temperatures, and relevant chemical parameters.
RTF provides OEMs and fine blanking companies with
highest quality deburring and zinc phosphating services –
and the opportunity to save both time and transport costs.
