Detailed Application Scenarios
Toy Industry Application
HY-916 super soft pad printing silicone is widely used for pattern and logo printing on plastic toys, educational toys, anime figures and other toy products. Toy products usually have irregular shapes with large curvatures and obvious concave convex surfaces, and normal hardness pad heads cannot fully conform. HY-916 pad heads are super soft with elongation ≥400%, perfectly conforming to complex curved surfaces, ensuring complete and clear pattern transfer. Uniform ink transfer produces full color cartoon patterns with clear edges. Flexible and durable, withstanding high volume printing with long service life.
Medical Device Industry Application
In the medical device industry, HY-916 is used for identification and scale printing on syringes, infusion sets, medical catheters and other medical products. Medical device products usually have special shapes with large curvatures and high requirements for printing quality. The super soft characteristics of HY-916 enable perfect conforming to special shapes, ensuring complete and clear identification printing. RoHS and REACH certified, safe and non toxic. Printed identifications are durable and wear resistant, meeting strict medical industry requirements.
Application and Operation Instructions
Step 1: Preparation
Prepare HY-916 Part A and Part B, digital scale, stirring rod, vacuum degassing machine, pad head mold, release agent, gloves. Ensure mold is clean and dry, apply release agent and let dry.
Step 2: Weighing and Mixing
Accurately weigh Part A and Part B by ratio 100:2. For example, 100g Part A + 2g Part B. Use digital scale for precise weighing.
Step 3: Stirring
Stir thoroughly for 3-5 minutes, scrape bottom and side walls to ensure uniform mixing. Stir gently to avoid bubbles.
Step 4: Vacuum Degassing
Degas for 5-8 minutes at -0.09MPa until no more bubbles rise. Critical step for pad head quality.
Step 5: Mold Pouring
Slowly pour degassed silicone into mold from one side, let flow naturally. Fill slightly above mold level.
Step 6: Curing and Demolding
Cure at room temperature 25°C for 2-4 hours. Demold carefully. Rest 24 hours before use for optimal performance.
Selection Guide
• HY-901 (23A): Economy grade, medium hardness, for small medium batch general printing
• HY-902 (28A): High wear grade, long life, for high frequency automated production lines
• HY-912 (25A): Multi color universal grade, high resilience, for multi color overprint fine printing
• HY-916 (16A): Super soft grade, excellent conformability, for large curvature irregular surfaces

FAQ
Q1: What products is HY-916 super soft pad head suitable for?
A1: HY-916 is specially designed for irregular curved surface products, hardness 16 Shore A, elongation ≥400%, suitable for toys, medical devices, irregular crafts, spherical and cylindrical products. For flat or slightly curved products, HY-901 or HY-912 is recommended.
Q2: What causes pattern deformation with super soft pad heads?
A2: Common causes include excessive printing pressure, pad head hardness too soft for the product, printing speed too fast, insecure substrate fixation. Reduce pressure, confirm hardness match, adjust speed, ensure substrate fixed.
Q3: What causes the silicone not to cure?
A3: Common causes include insufficient Part B or uneven mixing, contact with inhibiting substances, low ambient temperature below 15°C, expired curing agent. Check ratio and mixing, ensure proper temperature, use within shelf life.
