The midyear edition of the 2010 Stock Springs and Custom Springs catalog includes several new products. For example, the LeeP plastic-composite springs have stronger spring rates for applications requiring noncorroding, nonmetallic, inert materials. And Bantam mini compression springs are for applications requiring micro springs in a corrosion-resistant, heat-resistant material. Other new designs include compression instrument springs, smaller-diameter Redux wave spring, and an expansion of standard stock compression springs.
