We have many standard materials to choose from, including silicone and hard rubber .We are capable of making custom compounds to meet demanding applications including high temperatures, biocompatible, and chemical resistance. If you don´t find the size you need, we can help design and make a custom rubber stopper especially for you.

Molded products often need additional processing before they are ready for use. For example, require cryogenic deflashing as a finishing process. To support our various molding services, we offer a range of value-added capabilities.

Rubber stopper are used to block the filling port during the automatic filling process of battery cells. Prevent the electrolyte from leaking during the high-temperature curing process and causing the battery core to be scrapped. Each battery uses about 3-4pcs of different types of rubber nails. Rubber nail products not only need to have good sealing performance, but also need excellent electrolyte resistance to prevent reactions with the electrolyte, thereby affecting the electrolyte performance.
