These high quality Regular Round Rubber Bumpers are constructed in a closed mold through transfer molding, a process that combines the values of compression and injection molding. Bumpers created through transfer molding enable customers to develop their specialized parts with product consistency, reduced cycle times, superior control over part flashing and reduced finishing times.
