ImpactSilicone TubeWhat are the reasons for the quality issue?
1. Poor quality silicone tube raw materials with low performance and insufficient tensile strength can easily lead to cracking in silicone products. Therefore, strict quality control must be maintained in the raw silicone material selection.
Silicone products may adhere to the mold and be difficult to demold, or even crack, if the vulcanization process is incomplete, such as when the molding mold temperature is too low or the vulcanization time is too short. Therefore, it is necessary to increase the molding temperature or extend the vulcanization time during the vulcanization process.
3，Silicone ProductsHigh molding temperatures can make silicone products brittle during sealant molding, leading to easy cracking during demolding. Therefore, it is advisable to lower the molding temperature appropriately.
4. If the surface of the silicone products mold is too rough or积累dirt, it is not conducive to demolding and may cause cracking in rubber products. Simply polishing or electroplating the mold is sufficient.
Operational inconsistencies in demolding techniques can often lead to numerous issues. Therefore, operator training for demolding operations is essential. While it's inevitable that silicone rubber keycap products may crack, we can minimize the ratio of defective products caused by cracking through meticulous standardization. Generally, the majority of cracked silicone products are component parts. Hence, attention to these aspects during the production process is crucial.
