The process followed by a more advanced system, consists of a mix of Bentonite, Coal Dust, with 2-3 % water content. That’s why it is also called Green Sand Moulding. The machine Moulding process is to be done by Pneumatic Operated Machines using a match plate system for producing a mass quantity of casting. It’s a most advanced process comprising of following benefits:
- Consistent Dimensional Accuracy of the Component.
- Due to high-pressure moulding, weight uniformity for each job.
- Mass Production in a short time.
- Once a pattern match plate system is approved by checking the samples of castings, uniform quality is secured as the gating system is fixed.
- Patterns are customer property and the same may have longer life because it is mounted on the match plate.
- Lower rejection rate as zero dependence on the moulder.
- As dimensional consistency is maintained, one can minimize machining allowance, hence benefit by optimum weight of casting as well as lower machining time and machining charge at a machine shop. In short, minimum wastage.
- Most economical system for the company using the mass tonnage of casting.
