Technical audit for powder coating lines

A TDS describes the coating. It does not describe your parts, equipment or production routine. The same formulation can give a different visual or functional result when the substrate, geometry, film build or curing conditions change.

The purpose of the audit is practical: identify what should be checked before a coating is selected, sampled or introduced into production. It can be used for a new product, a change of supplier, a recurring coating issue or a requirement that the current system does not meet.

• The product, substrate and intended end use.
• Surface preparation and the condition of the part before coating.
• Part geometry, visible areas and difficult-to-coat zones.
• Application conditions, film build and the required colour, gloss or texture.
• Curing conditions, available oven data and the production cycle.
• Current defects, process limitations and acceptance criteria.
• Required TDS, SDS, certificates or external test documents.

The output is a clear route to testing, not an abstract report. Depending on the task, it can define the suitable coating direction, the conditions that need attention before a trial, the documents to review and the result that will be used to accept or reject the sample.

• A shortlist of relevant coating series or formulation directions.
• A record of process variables that may affect the result.
• A sample and production-trial plan based on representative parts.
• Agreed visual, process and technical acceptance criteria.
• The current documents that support the selected option.
