Production of rubber hole bungs begins by sourcing high quality NBR, FKM, and EPDM raw materials. Our mixing R&D team has then further optimized the mixes for performance and durability. Furthermore, prototyping and testing ensures that each optimized mix meets quality standards. Following the mixes, the mold R&D team utilizes one of their 10,000 mold designs to develop the proper mold shape and size. Compression and injection molding, among others, showcase reliability and quality in production. Care and concern for our customers’ needs leads to our sales team customizing collaborations. Our rubber hole bungs serve the agricultural, automotive, and mining industries, and offer better performance, durability and sealing.
