Screen Printing Silicone For Auto Oval Printing Machine
Screen printing silicone for an auto oval printing machine must have specific properties to ensure durability, flexibility, and high-quality prints. Here's what you need to know:
Key Properties of Silicone for Auto Oval Printing:
High Elasticity & Flexibility – Must stretch and conform to curved surfaces without cracking.
Excellent Ink Release – Should transfer ink cleanly for sharp, consistent prints.
Heat Resistance – Withstands curing/drying temperatures (if applicable).
Abrasion Resistance – Durable for long print runs without degrading.
Optimal Hardness (Shore A) – Typically 20°-30° Shore A for soft, flexible printing on curved surfaces.
Recommended Silicone Types:
Liquid Silicone Rubber (LSR) – Ideal for high-precision printing, good for fine details.
Addition-Cure Silicone (Platinum-Cured) – High durability, low shrinkage, excellent chemical resistance.
Application Process:
Mold Making – Create a silicone pad/stencil that fits the oval printing machine's requirements.
Curing – Ensure proper curing time/temperature for optimal hardness.
Installation – Mount the silicone pad onto the auto oval printer's mechanism.
Printing – Adjust pressure and speed for smooth ink transfer.
Maintenance Tips:
Clean regularly with silicone-safe solvents.
Store away from direct sunlight to prevent hardening.
Replace when signs of wear (loss of elasticity, poor ink transfer) appear.
