Design & Manufacturing Considerations

LEEDO Technology provides complete PTFE coating application consulting, from requirement evaluation to process optimization, helping customers identify the best surface protection solution.

Design and manufacturing considerations for PTFE coating
  • Non-Stick Requirement Evaluation
    Suitable PTFE formulations and coating thickness specifications are recommended according to contact material characteristics, cleaning frequency, and operating environment.
  • Low-Friction Application Design
    For sliding, reciprocating, or rotating mechanisms, contact pressure and speed are analyzed to optimize friction coefficient design.
  • Chemical Resistance Requirements
    Compatibility is evaluated according to the solvents, acid or alkali types, and concentrations used by the customer to ensure long-term coating stability.
  • High-Temperature Applications
    PTFE can withstand continuous operating temperatures up to 260°C, making it suitable for high-temperature engineering environments such as baking, painting, and curing ovens.
  • Sliding Mechanism Optimization
    Coating thickness control and surface roughness requirements are integrated to optimize part fit tolerances and improve overall mechanism performance.
  • Maintenance Cycle Extension Planning
    Coating protection reduces equipment wear and adhesion, extends maintenance intervals, and effectively lowers maintenance costs.
