Process

Titanium metal itself has poor plastic deformation. Over the years, the application market for titanium standard parts has been slowly developing from small to large quantities, resulting in slower development and updating of manufacturing equipment and products. Therefore, when titanium fasteners first entered the market, It is manufactured by mechanical processing;

Machining products is the use of machining turning, milling, lathe picking and other processing methods to process the bar to the finished product. The raw material waste is large, the yield rate is low, the process is large, the error is large, and the yield rate is low, resulting in high costs. Affect the application and popularization of titanium fastener products.

Hot forging refer to the processing method in which the material is heated and subjected to pressure deformation, so that the shape of the material meets the requirements of the drawing standard. The specific operation is to heat the material to a certain temperature and put it into a mold of a certain shape for forging and forming. It is also called hot upsetting or Red beat processing, hot forging is mainly used to produce larger batches of bolts, nuts and some non-standard shaped parts, which improves processing efficiency, ensures product consistency, improves product yield, and reduces material and processing costs. ；

Cold heading is a method of using the plasticity of metal materials to apply pressure or cold drawing using a cold heading machine to achieve the solid deformation of the metal, and to forge the top of the wire and the rod into a shape at room temperature.

Cold heading is mainly used to manufacture bolts, nuts, screws, rivets and other parts. The raw materials can be titanium and titanium alloys or other non-ferrous and ferrous metal materials. Cold heading can make the utilization rate of raw materials reach more than 90% or even higher;

Cold heading is mostly carried out on a dedicated cold heading machine, which facilitates continuous, multi-station, and automated production. Cutting, heading, forming, chamfering, diameter reduction and trimming can be completed in sequence on the cold heading machine. The production efficiency is high. At present, only pure titanium materials can be used, and the working speed can reach 50~150 pieces per minute, every 8 hours It can produce 30,000 to 70,000 pieces per hour, with extremely high efficiency, reducing processing costs, lowering prices, and earlier delivery.

JHY Company started to develop cold heading machine products in 2019. After two years of hard work, the finished products will gradually be sold off the line in early 2021. The current production range is M1.6-M8 pure titanium standard parts.
