It is proposed to replace the cast iron casing of a power tool with one with precisely the same dimension molded from nylon. Will the material cost of the nylon casing be greater or less than that made of cast iron? Use data from the CES EduPack or another source (specify source) to find out.

Solution

The cost of nylon casing will be less as compared to cast iron.Eevn automobile maniold are being replaced nowdays by fiberglass reinforced nylon to lower the weights and improve the efficiency.Portable electric tools and small kitchen appliances housings are no longer made of cast iron or stell or aluminium ,nut have been replaced with the nylon .These plastics improve the toughness ,electric insularion ,design ,flexibility and styling,nd even they are weigh less and provide ffcicient moulding at lower costs.

If we look at the present cst of cast iron it is :

Cast iron #1: prepared machinery cast with no steel $165.00

and Nylon casing price is nearly $ o.6

is a robust and durable artificial fiber traditionally used for strong tire casings. The artificial fiber can be very light but is not as supple as Corespun. Our Nylon casings set a new standard in their class. Vittoria offers casings in Nylon 180 TPI, 150 TPI, 120 TPI, Nylon 60 TPI, and Nylon 26 TPI, each equipping tires at its respective point on the price-performance scale, and all conferring the Vittoria characteristics of comfort, speed, and good handling.

so definitely nylon casing is efficient and cheap as compared to cast iron casing .
