OUR PROCESS FLOW

A comprehensive 20-step process ensuring the highest quality zinc plating standards.

1

Goods Inwards

Receipt of raw materials and components, ensuring all documentation is in order for tracking.

Log EntryTagging
2

Incoming Inspection

Initial quality check to verify the condition of incoming parts before processing begins.

Visual CheckQuantity Verification
3

Storage

Secure storage of components in designated areas to prevent damage or contamination prior to plating.

Inventory ManagementSafe Storage
4

Saw Dust Cleaning

Removal of oil, dust, and loose particles using sawdust cleaning methods for initial surface prep.

Dust RemovalSurface Cleaning
5

Soak Cleaning

Immersion in cleaning agents to loosen and remove stubborn oils and grime from the metal surface.

DegreasingOil Removal
6

Water Rinsing (2 Stage)

Thorough two-stage water rinsing to ensure no cleaning agents remain on the parts.
