The retreader based in North Carolina in the USA has been able to improve its productivity, reduce costs and crucially, prevent tire envelope damage by switching from metal to composite staples. The metal staples were puncturing the tire envelopes, which each cost over US$110, causing damage to the tire and ultimately, tire failures. Completely non-metal, the Black Magic staples melt during the cure cycle and have a low melting formula for low temperature cure chambers.
