Automatic billet casting machine

This machine is made by my company's independent research and development of products, which has conventional digital machines type and CNC machine type, mainly used for leaded and lead-free solder and tin alloy billet material production.


The machine is constructed by the rack, incubator, shaping device, traction devices, cutting device, cooling system, hydraulic system and electrical control system.

After melting furnace, the tin water is pumped into the incubator, and then the incubator will adjust the tin water temperature to optimum pouring temperature. Then valve opens, the tin water fills shaping device, after sufficient cooling , the billet is pulled out by the traction device, when it reaches pre-set length, the cutting device will start cutting and make it roll to designated position after cutting off. The whole process is automatically controlled.

This machine has the advantages of advanced control system, according to different solder material composition, it can set the corresponding traction time, to ensure the reliability of traction. When short of material or full of material , it can automatically alarm to ensure the safety of equipment and personnel.

According to the length of the bar material for different extrusion machine, the corresponding cutting length can be set to meet the requirement of the next working procedure.
 

The solder billet casting machine can combine with the conventional melting furnace by tin pumping device, to automatically fill molten tin water into the incubator. The machine can also co-work with high melting furnace , the tin water can be filled into incubator directly  by opening a tin discharging valve.

Features:
1, High production efficiency: capable of continuous automatic casting to achieve a mechatronics.
2, bar good quality: smooth surface, no oxidation, no holes, end formation, the same length.
3, easy to operate, can greatly reduce the labor intensity, safe and reliable.
4, the machine is compact and easy maintenance.
