Infusing lubricants to nozzle of lead screw of coil soldering machine regularly , it can lubricate the lead screw , reduce friction ,prevent it from rusting. In furnace of coil soldering is better to divided into several heating zone , ,there is an pairs of cartridge heater in every zone ,several cartridge heater work at the same time ,make sure it is evenly heating and speed up heating. Tin is easy to be oxidized , it will cause oxide inclusion ,it will impact the soldering looking, the machine have to scrape the oxide every time before soldering . when coil soldering machine works , after dipping the flux , the pin of bobbin should be wet , if directly have it dipped into tin furnace .It will cause smoke, it will impact the thermostatic status of the internal machine .for some high demand product , it have to blow-dry the pin of bobbin before dipping into hot tin furnace. Changing the tin of whole tin furnace of coil soldering machine once per month is sugges...
Ductile iron, also known as nodular cast iron ， spheroidal graphite cast iron, and SG iron. It is obtained by adding a certain amount of nodularizer and graphitizer in the molten iron before casting to help with the crystallization of spherical graphite, which has high strength, good toughness and plasticity, and is a good material with advantages of both steel and cast irons. Steel square tube refers to a square steel pipe, made of carbon steel, cast steel or other materials, is what traditional winding machine manufacturers use to make machine base. So what's the difference between the two materials? 1. Ductile iron's yield strength is higher than steel square. Ductile iron's yield strength ratio is 0.6 ～ 0.65 and steel's is only 0.5 ～ 0.55. The yield strength means that the external force above this limit will cause permanent deformation of parts.Therefore, steel square's ability to resist pressure is weaker, prone to plastic deformation, ...
