what are the requirements for the compatibility of silicone materials with the oval printing machine?

When the automatic oval printing machine uses silicone ink for printing, what are the requirements for the compatibility of silicone materials with the equipment?
1. Screen tension stability
Requirements:
Tension maintenance range: 18-25 N/cm (tension fluctuation ≤±2 N/cm when the oval machine is printed at high speed).
Fatigue resistance: After 100,000 continuous printings, the tension decay is ≤10%.
Material selection:
Polyester fiber (PET) based silicone screen: suitable for high-precision printing (line width ≥0.1mm).
Stainless steel based silicone screen: suitable for high tension and long-cycle printing (such as continuous printing of textiles).
2. Compression resistance of rubber head
Requirements:
Compression permanent deformation rate <5% (tested at 10% compression for 24 hours).
Hardness change rate <±3A (after 500 hours of continuous use).
Applicable scenarios:
Curved printing: Choose silicone with low compression permanent deformation (such as Shin-Etsu KE-1310ST).
High-precision pattern: Use a composite rubber head with a hardness gradient distribution (such as 50A for the surface layer and 30A for the inner layer).
3. Curing speed matching
Requirements:
Silicone ink surface drying time ≤10 seconds (UV curing type) or ≤30 seconds (solvent type).
Full curing time ≤24 hours (room temperature) or ≤30 minutes (baking at 80℃).
Equipment adjustment:
If the ink cures slowly, increase the UV lamp power (such as from 80W/cm to 120W/cm) or extend the baking channel length.
