The six basic steps in making sand castings are, (i) Pattern making, (ii) Core making, (iii) Moulding, (iv) Melting and pouring, (v) Cleaning Pattern making - Pattern: Replica of the part to be cast and is used to prepare the mould cavity. It is the physical model of the casting used to make the mould. Made of either wood or metal.
Metal casting processes
tions like shell making or post-production processes like the grinding or polishing of the cast parts. The robot-based automation of wax tree mounting is the next step for progressive foundries looking for new ways to optimize the output and flexibility in investment casting. The IRB 7600’s long-arm version features a
The Right Choice for Higher Productivity
Shell Molding Process • Shell-mold casting yields better surface quality and tolerances • The 2-piece pattern is made of metal (e.g. aluminium or steel), it is heated to between 175°C- 370°C, and coated with a lubricant, e.g. silicone spray • Each heated half-pattern is covered with a mixture of sand and a thermoset resin/epoxy binder.
