PTFE Non Stick Coating for Mould Recoating

When Should a Mould Be Assessed?

Peeling, scratches, exposed areas and declining release performance are reasons to request a review. Operators may also notice more residue or a change in cleaning effort. Record when the problem began and where it appears.

A worn surface does not explain the cause by itself. Before renewing PTFE non stick coating, the team needs to consider operating conditions, cleaning, previous repairs and the old coating. Repeating the same work without reviewing those details may repeat the problem.

Recoating or Replacing the Mould?

Recoating treats the surface. It does not restore missing mould features, repair cracks or correct distortion. If the underlying tool has damage, other work or replacement may be necessary before a coating decision.

PTFE non stick coating should follow an assessment of whether the mould remains useful. Share the required dimensions and any changes in product shape. A tool that looks acceptable in a photograph may still need physical inspection.

Signs to Photograph Before Sending the Mould

Take a full view showing the mould shape and cavity layout. Add close photographs of peeling edges, scratches, residue and exposed areas. Good lighting helps show the surface without hiding defects in shadows.

Number the affected cavities and mark their positions on a drawing. If you have earlier photographs, include them for comparison. Tell us whether the surface changed gradually or after a particular cleaning, repair or production event.

Benefits of Reviewing PTFE Non Stick Coating

Understand the Existing Problem

A review helps identify the information needed before another coating application. A photograph may show damage, but it does not prove the root cause.

Protect Useful Tooling

If the mould remains suitable, recoating may allow further use. Compare the proposed work with repair or replacement rather than assuming one option always costs less.

Update the Specification

The current production conditions may differ from the original job. Discuss temperatures, cleaning methods and release needs again before repeating an old specification.

Our PTFE Non Stick Coating Recoating Process

Assess the Old Layer

We review its condition and any available coating history. Tell us about earlier recoating jobs and repairs.

Select a Removal Method

The removal approach must suit the mould and existing layer. Do not assume every old coating can be treated in the same way.

Reinspect the Mould

Removing the layer may reveal defects that were difficult to see earlier. Any change in scope needs discussion before further work.

Prepare and Mask

Preparation follows the selected coating requirements. Mark critical faces, vents, threads and fitted features that must stay protected.

Apply and Cure

PTFE non stick coating needs the specified application and curing conditions. The mould must be suitable for that process.

Review the Finished Work

Agree coverage, finish and any dimensional checks in advance. Keep the acceptance requirements clear when requesting the quote.

Does Recoating Change Mould Dimensions?

Removing an old layer and applying a new one affects the finished surface. The important question is whether the final dimensions meet your drawing. Previous wear and repairs can also influence fit.

Before renewing PTFE non stick coating, share tolerances and identify critical features. Tell us about inserts, parting faces and areas that must remain uncoated. Coating cannot recover a worn dimension simply because the surface looks smooth afterwards.

Cost, Timing and Scope

The quote depends on mould size, cavity detail, old coating condition and removal work. Masking, preparation and agreed inspection requirements also matter. Unknown previous layers may require further assessment before the scope becomes clear.

Request a PTFE non stick coating quotation with photographs and job history. Ask what happens if inspection reveals additional damage. Delivery timing follows the reviewed scope and current schedule, so confirm the plan before arranging a production shutdown.

Care After Mould Recoating

Follow the approved care instructions when the mould returns to use. Confirm cleaning tools, compatible chemicals and operating limits for the selected system. Make sure the people using the tool receive those instructions.

Track release performance and take photographs during routine checks. If a similar wear pattern returns, record the location and working conditions. This information supports a more useful follow-up than simply saying the coating did not last.

Keep a Useful Coating History

A simple history can make the next inspection more useful. Record when the mould entered service, when release changed and which areas needed extra cleaning. Include any available coating specification and details of later repairs.

Explain whether production conditions changed before the damage appeared. A new cleaning method or a different operating cycle may be relevant, but neither proves the cause alone.

Keep the agreed recoating scope with the mould records. It helps the team compare future wear with the condition documented before this job began.

Share these records when requesting another assessment.
