HY-916 Ultra Soft Pad Printing Silicone for Large Curved Irregular Surface Low Hardness High Deformation

Hongye HY-916 is an ultra soft two component RTV Pad Printing Silicone developed by Shenzhen Hongyejie Technology Co., Ltd. for large curved and irregular products. With 16±2 Shore A hardness, it is the lowest hardness and strongest deformation model among four series, with elongation ≥400 percent, tensile strength ≥2.5MPa and tear strength ≥10kN/m. The rubber is soft with good elasticity, can fully deform and conform to various complex curved surfaces during pressing.

Many enterprises encounter problems when printing large curved surfaces, deep concave surfaces and irregular products. Standard hardness pads cannot fully conform to product surfaces, causing incomplete pattern transfer, blurred edges and partial missing print. HY-916 ultra soft model specifically solves this problem. The low hardness high deformation rubber can fully wrap large curved surfaces during pressing, making complete contact with product surface and ensuring complete pattern transfer. Ideal for spherical, oval, humanoid, animal shaped large curved toys, irregular gifts, craft products and cosmetic bottles with irregular surfaces. Multiple colors available including red, yellow, white and green four standard colors. Standard 100:2 mixing ratio, easy operation.

Standard 100:2 mixing ratio, easy operation, suitable for small batch multi variety production characteristics of gift and craft industry.

Operating Instructions

Step 1 Pad Mold Preparation: Thoroughly clean the pad mold, wipe with alcohol and apply mold release agent evenly, leave 5 to 10 minutes to dry. Pay special attention to curved surface cleaning for large curved pad molds. Place mold on a level stable surface.

Step 2 Component A Preparation: Stir component A base rubber thoroughly for 1 to 2 minutes before pouring to ensure uniform color and filler distribution, scrape bucket walls and bottom. HY-916 has lower viscosity, stir at moderate speed to avoid excessive bubble entrainment.

Step 3 Weighing and Mixing: Accurately weigh A and B at 100:2 ratio by weight using electronic scale, within ±5 percent tolerance. Mix thoroughly for 3 to 5 minutes, scraping container walls and bottom to ensure complete uniform mixing. HY-916 rubber is softer, avoid over mixing which introduces bubbles.

Step 4 Pouring and Degassing: Slowly pour mixed silicone from one side of the mold, let it flow naturally to fill. Fill to about 80 percent. Use vacuum at negative 0.09MPa for 2 to 3 minutes if available, HY-916 lower viscosity makes degassing easier. Without vacuum, let sit 5 to 10 minutes for natural bubble release.

Step 5 Curing and Demolding: After degassing, cover the mold and cure at room temperature 25°C for 2 to 4 hours. For faster curing, heat at 60°C for 30 to 60 minutes, temperature not exceeding 100°C. HY-916 rubber is softer, be extra careful during demolding, gently remove to avoid tearing and deformation. Let rest 24 hours before use.

Step 6 Usage and Maintenance: Wipe pad surface with alcohol before use. Do several test prints first to condition the surface. For large curved product printing, adjust pressure and speed, moderate pressure ensures full pad conformity. Gently remove residual ink with clean nonwoven cloth or tape. Wrap with plastic film when not in use, store in cool dry place, avoid compression deformation.

Precautions

Use polyethylene, nylon or nitrile gloves, do not use natural latex gloves. Avoid contact with sulfur containing substances, amines, phosphorus compounds, tin cure silicone and PVC as these may inhibit cure. Use calibrated scale for accurate 100:2 weighing, mix thoroughly for 3 to 5 minutes. HY-916 rubber is softer, avoid forceful pulling or compression during demolding and use to prevent tearing and deformation. Heat curing temperature not exceeding 100°C. Maintain good ventilation. Component B has mild irritation, avoid direct contact with skin and eyes. Seal containers immediately after use.

Storage

Store in sealed containers below 25°C in dry ventilated area, avoid direct sunlight, keep away from sulfur containing substances, amines, food and strong chemicals. Shelf life 12 months from production date. Seal immediately after taking material. Refrigeration at 5 to 15°C extends shelf life, warm to room temperature before opening to avoid condensation. Store components A and B separately. HY-916 rubber is softer, avoid heavy object compression during storage to prevent pad deformation. Store away from fire and heat sources with good ventilation.

FAQ

Q: Will HY-916 ultra soft pad be too soft causing pattern deformation?

A: No. HY-916 at 16 Shore A is the lowest among four models but still within reasonable pad printing silicone hardness range. The rubber is soft but has sufficient elasticity, quickly recovers shape after pressing and will not cause pattern deformation. On the contrary, HY-916 ultra soft pad can fully conform to large curved surfaces ensuring complete pattern transfer, with better clarity and completeness than standard hardness pads. Only under excessive pressure or too long pressing time may slight deformation occur, which can be avoided by adjusting printing pressure and speed. HY-916 is the best choice for large curved surface products.

Q: How is the service life of HY-916 pads?

A: HY-916 ultra soft pad service life depends on printing frequency, product shape, ink type, cleaning method and maintenance. Due to lower hardness, wear resistance is slightly less than higher hardness models like HY-902. For regular production, it typically lasts 10000 to 30000 prints. However for large curved and irregular products, standard hardness pads simply cannot print normally, HY-916 is the only viable choice and its service life fully meets production needs for such products. Proper use and maintenance can effectively extend service life, including adjusting appropriate printing pressure, removing residual ink with tape instead of solvent wiping, and wrapping for storage avoiding compression deformation when not in use.

Q: What to do about partial missing pattern when printing large curved products?

A: Partial missing pattern when printing large curved products is mainly caused by pad hardness too high, unable to fully conform to product curved surface, resulting in insufficient local contact. Solutions: First, replace with lower hardness pad like Hongye HY-916 ultra soft model, 16A hardness with elongation ≥400 percent, can fully conform to large curved surfaces. Second, appropriately increase printing pressure to 让 pad deform more fully and conform to product surface, but do not over pressurize to avoid pattern deformation. Third, adjust pad shape, design more conformable pad shape based on product curvature, custom pad mold if necessary. Fourth, check if product has deformation or uneven surface, ensure accurate product positioning. These methods can basically solve partial missing pattern on large curved products.
