| 500 ## - GENERAL NOTE | |
| General note | Sand Casting is very old technique for casting metal parts. In this process a pattern is<br/>made which is a replica of the desired part. The pattern is placed in a box and curing sand is<br/>poured around it. After curing of sand, pattern is detached so that replica is imprinted in the<br/>sand. Then metal in molten form is added into the hollow portion and desired part is obtained<br/>after cooling. The process is cheap and incorporates all kinds of metals, however, the<br/>correctness of the final part is primarily dependent on the correctness of the pattern itself.<br/>Rapid Prototyping (RP) is a collection of contemporary manufacturing methods which<br/>create the part straight from Computer Aided Design (CAD) model using layer-by-layer<br/>deposition technique. The CAD model is first sliced and each cross section of the CAD<br/>model is used as a guide to deposit material at the desired location. The RP process varies<br/>with the technology being used. Additive Manufacturing (AM) has been of significance<br/>importance because of its precision and overall time reduction in product development<br/>process. Moreover, a prototype can be developed to know the functioning of the actual part<br/>which gives flexibility to designers to vary the design to eliminate the inaccuracies.<br/>A case study was undertaken in this research work in collaboration with KSB Pumps<br/>Hassan Abdal, Pakistan. KSB pumps are a well renowned manufacturers of pumps for variety<br/>of applications. The company was facing problem in one of their pumps named ‘Sewatec<br/>250-401’ whose performance (efficiency) was not up to the desired standards. The impeller<br/>of the pump was being manufactured through manual pattern making and sand casting<br/>techniques. After detailed study of the manufacturing process of the said pump, it was<br/>observed that the vane of said impeller was manufactured in a crude way leading to doubts in<br/>its accuracy. Therefore, it was decided that the vane of this pump will be manufactured<br/>replacing existing manual pattern making with RP patterns and performance of the new and<br/>old pumps will be compared.<br/>The pump manufactured using RP technique showed higher efficiency (83.6%<br/>efficiency) as compared to the one manufactured using manual patterns (74% efficiency) and<br/>met all performance standards (82% efficiency). The manufacturing through RP reduced the<br/>overall cost of the manufacturing by 1/8th and considerably reduced the time to manufacture<br/>(by 11 weeks). |
