Electronics Factory Cuts Defect Rate with HY-933 Addition Silicone

Problem Background The factory products require printing brand logos, model markings and certification symbols with patterns as small as 0.5 millimeter text. Previously using ordinary condensation cure silicone, curing released ethanol causing about 0.3 percent head shrinkage, resulting in fuzzy text edges and misaligned multi color prints. Workers had to repeatedly adjust machine parameters. Various attempts including ink adjustment and plate replacement failed, keeping defective rate around 15 percent with over twenty thousand pieces scrapped monthly.

Discovering Hongye Silicone In early 2026, the factory learned about Hongye addition cure silicone at an exhibition. Hongye technicians identified high shrinkage as the core cause and recommended HY-933. Using platinum catalyst system with no small molecule release, HY-933 has linear shrinkage below 0.1 percent, making head dimensions nearly identical to the mold and solving dimensional deviation fundamentally. With 34 Shore A hardness and good rebound, it is especially suited for fine text and multi color registration.

Trial Results The factory first ordered 5 kilograms for trial, using brand new containers and tools to avoid tin sulfur amine contact. Results were excellent: heads matched plates precisely, transferred text edges were sharp with 0.5 millimeter text fully visible, and multi color registration deviation was nearly zero. After one month, defective rate dropped from 15 percent to below 3 percent, reducing monthly scrap by over sixteen thousand pieces and saving more than thirty thousand yuan, while production efficiency rose about 20 percent.

Ongoing Partnership After successful trial, the factory designated HY-933 as standard material with stable monthly orders of 200 kilograms. Hongye technical team provides regular follow up including operation training and troubleshooting. The factory manager noted that although addition silicone costs slightly more, the savings from reduced defects and improved efficiency far outweigh the material cost increase.

Hongye Silicone reminds that addition cure silicone must avoid contact with tin, sulfur, amine substances, and containers tools must be fully separated from condensation type to prevent poisoning and non curing. With proper operation, addition cure silicone offers clear advantages in high precision printing.
