03 — Surface finishing
Complete powder coating, in-house
Most fabricators send parts out for coating and lose a week to someone else's queue. Ours never leaves the building — so lead time, finish quality and rework all stay under our own control.
STAGE 1
7-tank pre-treatment
Degreasing, rinses, pickling, activation and zinc phosphating — each tank labelled with its chemical, concentration and dwell time at the tank itself.
STAGE 2
Cyclone-recovery spray booth
Electrostatic application with powder recovery, so colour changes are controlled and overspray is recycled rather than wasted.
STAGE 3
Gas-fired curing oven
Controlled cure cycle, followed by film-thickness and adhesion sampling at QC Gate 1 before the part moves on.
Pre-treatment line, spray booth and curing oven — all in-house
