How to Choose Extra-Soft Pad Printing Silicone? Hongye 916 So
In pad printing production, one of the most common challenges is achieving consistent, high-quality prints on large-area, large-curvature, and irregularly shaped products. Conventional pads with standard hardness often make full contact in the center but leave the edges untouched, resulting in broken patterns, missing ink, ghosting, and reduced production yield. Shenzhen Hongyejie Technology Co., Ltd. (Hongye Silicone) has developed the 916 extra-soft pad printing silicone as a professional solution to this exact pain point.
Why Complex Curved Surfaces Need Extra-Soft Pads
Pad printing works by using the elastic deformation of the silicone pad to transfer ink from the etched plate onto the product surface. When the product has a large curvature or a broad printing area, the pad requires significant deformation to achieve complete contact. A pad that is too hard will not conform sufficiently, causing broken or blurred edges. Conversely, a pad that is too soft may collapse, lose resilience, and distort the printed image. The 916 silicone achieves an optimal balance: at just 13±3 Shore A, it is soft enough to fully conform to curved surfaces, yet resilient enough to recover its shape quickly after every press — ensuring consistent print quality cycle after cycle.
Core Advantages of the 916 Extra-Soft Silicone
First, exceptional conformability. The ultra-low hardness allows the pad to naturally follow the product's curved surface during pressing, maximizing the contact area and ensuring uniform ink transfer. This is especially valuable for large toy housings, sculpted craft gifts, and curved lampshades. Second, outstanding resilience. Despite its softness, the 916 recovers rapidly after each press with no residual deformation, maintaining print accuracy over long production runs. Third, strong durability. Although soft to the touch, the material delivers excellent tensile and tear strength, so the pads resist damage and offer a long service life. Fourth, superior print quality. The fine, impurity-free texture ensures even ink pick-up and release, producing sharp, clean patterns with no particles or bubbles.
Industry Applications and Customer Feedback
The 916 extra-soft pad printing silicone is already widely used across toy manufacturing, craft gifts, lighting, home appliances, and automotive interiors. Multiple toy manufacturers report that after switching to 916 pads, print yield on large-curvature figurines improved from approximately 85% to over 98%, and pad replacement frequency decreased noticeably. Lighting industry customers praise its stable performance on curved lampshade surfaces, where large solid-area patterns print without ink breakage or color variation.
Selection Recommendations
Hongye Silicone's technical team recommends matching pad hardness to the specific application: standard hardness models such as the 912 for flat or small-curvature products; the 916 extra-soft for large-curvature, large-area, and irregular surfaces; and slightly harder models for fine, small-pattern printing. The company offers free sample testing and can recommend the most suitable silicone based on each customer's specific product geometry and printing requirements.
