Having introduced the Italian advanced technology and had many years of experience, our company has developed the ZL-350 High speed Chain Weaving Machine which has the function of weaving perfect and elegant chain after processing the 12-24k gold, silver and K platinum, copper line of single-sprocket 0.30 to 0.50 and double-sprocket 0.21 to 0.40.Contrasted with the machine chain, it is obvious that the manual chain is not very impressive for it irregular shape. The difference is that the machine chain is of perfect shape and smooth clear surface, furthermore, the machine can work out many styles of necklace and hand chain with different shape and weight. It also can work with table chain or other chains (If working with hammer chain machine, it can produce much more styles of chain with better effect.) The machine has such high output that it can weave 250 to 400 circles per minute and produces 25 to 30 pieces of chain each hour counted by 0.30 double-sprocket chains. Prevailing in the jewelry trade, the product is certainly becoming the first choice for intelligent businessman, and we believe it would create much more profits for you.
