Define critical dimensions
OD, ID, wall thickness, length? Micro parts (sub-10mm features) demand precision tooling.
Specify tolerance requirements
±0.02mm achievable. Tighter tolerances may require secondary operations (grinding, laser trim).
Select the elastomer
Silicone for biocompatibility/flexibility, FKM for chemical resistance, specialty compounds for specific applications.
Identify inspection requirements
Optical/CMM measurement? Leak testing? Micro parts need precision metrology.
Common micro-component failures
Dimensional Variation
Even very small deviations from specified dimensions can prevent proper assembly, affect sealing performance, or interfere with the operation of precision equipment. Consistent manufacturing and quality inspection are essential to avoid this issue.
Tear
Thin walls and delicate geometries may lead to tearing during installation or under repeated mechanical stress. Proper material selection and careful handling help improve durability.
Flash
Excess rubber remaining along the mould parting line can interfere with assembly, sealing, or movement of precision components. Effective mould design and post-mould finishing are important to eliminate flash.
Compression Set
Over time, prolonged compression may cause the rubber to lose its ability to recover its original shape. This permanent deformation reduces sealing effectiveness and can lead to leakage or reduced performance.
Material Shelf life
Exposure to elevated temperatures, chemicals, UV radiation, ozone, or ageing can gradually reduce the rubber's elasticity, strength, and durability, ultimately affecting the component's performance and service life.
