Powder metallurgy methods of economic evaluation of mechanical parts

Mechinery parts powder metallurgy product designers, during the design, you must make an assessment of production costs in order to report a delivery price. Designed with a longer period of time engaged in the production or marketing staff, based on their experience, even if not the entire production process of all the factors necessary comprehensive, but also in general can be made ahead of economic feasibility assessment.
Main cost of powder metallurgy parts powder metallurgy parts with the actual operation of the production process and production of content, batch size, and costs related to mold. In particular, and mold production costs are closely related with the batch size. A complex shape parts, tooling and production costs reflected in the grade requirements of press repression despite the higher costs, but large quantities, when allocated to a single piece, the cost can be significantly reduced.
Direct cost of production of powder metallurgy parts is divided into five areas: materials; mold; repression; sintering; follow-up treatment.
The cost is generally higher than the metal powder form of the corresponding metal casting cost, it is because the metal ingots made ​​of powder to consume energy and other factors. Of course, the powder metallurgy process, the material utilization is high, therefore, made the total cost of product material may not be higher than the manufacturing process of casting and forging parts. Powder metallurgy of the final product material utilization is generally 95% to 98%, metal parts for the approximate calculation of the cost of raw materials:
The cost of materials should also include lubricants, additives and other alloying elements, including the actual cost of raw materials.
