Drawing & Revision
Significant surfaces, no-coat areas and critical dimensions.
Trials, R&D & Development Support
BMF supports coating trials, sampling, approval batches, SST evaluation and application-led route selection.
Workflow
A structured route from enquiry to approval batch.
Trials work best when the customer shares drawing, material, target finish, standard, acceptance criteria and actual use condition.
Initial review
Review drawing, material, surface condition, geometry, threads, fitment areas and service environment.
Review drawing, material, surface condition, geometry, threads, fitment areas and service environment.
Route selection
Select zinc flake, Xylan, blasting, phosphating or passivation route with thickness / mass and curing considerations.

Sample processing
Process trial quantity with observations on coverage, finish, masking, curing and handling sensitivity.

Inspection feedback
Check finish, DFT, adhesion/fitment where relevant and salt spray support if required.
Check finish, DFT, adhesion/fitment where relevant and salt spray support if required.
Approval batch
Refine route, define inspection expectations and support transition into repeat production.
Refine route, define inspection expectations and support transition into repeat production.
Inputs
Information that reduces trial time and rework.
Incomplete RFQ data usually creates unnecessary trial loops in technical surface finishing.
Material & Condition
Base material, heat treatment, current surface and prior coating.
Performance Target
Thickness, SST, wear, conductivity, friction or appearance requirement.
Approval Criteria
Inspection format, sample quantity, test method and sign-off process.
