Our North American customers have been buying hydraulic crimpers that accept the U type dies. We have been selling the U type dies with hexagonal shape, but our customers are now requesting the other shape dies similar to the Burndy, Huskie, T&?B, and other brands. The CYO400 type is about the right size, but we need a bigger selection of dies than the 50-400 mm2 hexagonal shape.Initial order would be for samples to be evaluated by our Tianjin office. We do not ask for and we do not accept free samples, so we would pay for the goods plus the shipping to Tianjin. A Taizhou supplier with a local Rep Office in Tianjin would be advantageous. We can buy the complete set of crimpers with dies if the price and quality is competitive, or we can buy just the dies alone.At this time, we are looking for suppliers that already make these dies. We are really reluctant to help a supplier with the development work because it has taken too long in the past and the results were usually disappointing.
