Mold release & non-stick

Reduce adhesion of molding materials while balancing mold release, cleaning and mold dimensions.

The following are laboratory / historical comparison data and are not a guarantee for any workpiece; formal specifications are subject to engineer confirmation and the quotation.

PROCESSING · PERFORMANCE

Processing customers, start here

Reduce sticking, improve cleaning and release

Evaluated based on the contact material, operating temperature and cleaning method.

Please describe the resin, adhesive or other contact substance, as well as the current sticking problem, operating temperature and target life. Food-contact or similar requirements need separate confirmation of the corresponding compliance documents.

Conclusions first

PTFE composite electroless plating is a candidate that balances mold release and coating strength.

Pure PTFE coatings and composite electroless plating each involve trade-offs; a single metric should not be used for an absolute ranking.

Food-contact uses must be checked against applicable Chinese regulations and specific compliance documents; overseas wording cannot simply be reused.

Test conditions

For a specific workpiece evaluation, state the material, operating environment and acceptance requirements; read the test conditions separately for each data group on this page.

Data & interpretation

PTFE composite electroless plating vs. pure PTFE coating | qualitative comparison

The table scrolls horizontally; the first column keeps the comparison items.

Evaluation itemPTFE composite electroless platingPure PTFE coating
HardnessSupported by a metal matrix; actual hardness confirmed by model and heat treatmentPolymer coating; values depend on formulation and process
Wear resistanceRated relatively well in historical data; must be tested against the counterpartWear mode and coating life must be checked
Thickness precisionPrecision dimensional requirements can be evaluated; tolerances need confirmationCoating thickness and dimensional build-up should be checked
Uniformity on complex partsChemical deposition suits complex shapes; holes and slots need process evaluationCoverage and uniformity depend on the application method and shape
Mold release & non-stickRated good in historical comparisonRated better in historical comparison; actual results depend on the molding material
How to read this table

This table is a qualitative comparison from historical data, not a numerical ranking under identical conditions. When purchasing, specify release force, surface quality, cleaning interval and dimensional acceptance separately, and confirm with samples.

Selection advice & data boundaries

Application cases are summaries of historical data and are not customer projects verified by this site or guarantees of results. Actual solutions require sample testing.

Food-contact uses: request specific compliance documents from sales and check the use, food in contact, temperature, time and applicable Chinese regulatory requirements; no food-contact compliance commitment is made before the corresponding documents are obtained.

Please add the molding material, mold temperature, cleaning agent, dimensional tolerances and release cycles.
