Shell Core Making Molding Line Of Resin Sand Foundry

Product description of shell core molding line

The shell moulding line is developed for continuous prodction of shell moulding process with layout of continuous line or open line.The whole line is equipped with bottom sand filling and vibrating table,core setting station,top sand filling & vibrating station,pouring station,cooling,and flask turnover device;as well the sand preparation system,resin coated sand reclaimation system.

The steel shot filling process is a process in which the core is placed in the flask and the steel shot is filled to reinforce the core.After pouring,the castings are cooled by steel shots.The cooling speed is faster and the process has better venting.The steel shot can be recycled and reused. Compareing to normal sand casting process,the shell moulding process has advantages of lower investment,compact area occupation,easy operation,high efficiency,low sand consumption,less dust pollution,and use noise.And the castings have better surface,better dimension accuracy,and good material properties.

Shell core foundry process is to use hot core box process equipment for shell core of precoated sand.Its working process of sand filling and compaction is done at the same time, and immediately on the hot core box of hardening, reduce labor intensity, flexible operation of portable, easy to grasp, use electric heating, temperature automatic control, work easy to keep clean, create conditions for core making process of mechanization and automation.A cycle only ten seconds to a few seconds, can be produced for casting cores.With shoot core machine manufacturing core size precision, smooth surface.Widely used in foundry machinery.
The advantages of shell core machine:
1, high production efficiency, the working process of the shell core machine is note sand and tight at the same time, and immediately preheating hardening in the core box, a cycle only ten seconds, can be produced for casting cores.
2, the die set automatically turn 180 ° fell free form shell core sand, this technology can save 40% of precoated sand.
3, good quality of sand core, can shoot any complex degree of sand core, and the precise size, smooth surface, and thus can reduce casting processing capacity.
4, can save a lot of core with auxiliary equipment and tools, such as bone core drying furnace, drying device, core, wax line, etc.
5, reduce labor intensity, flexible operation is simple, easy to use, and USES electric heating, temperature automatic control, easy to clean the work site, create conditions for core making process of mechanization and automation.
