Product design process

Product design process is a set of planned activities that convert an idea into a product and make it commercially available to the end user

Mechanical Transmission

Mechanical power transmission is the transfer of energy from where it’s generated to a place where it is used to perform work

Casting processes

Process in which molten metal is poured into a mould that contains a cavity of a desired shape and allowed to cool down to form a solidified part

Additive manufacturing

Additive manufacturing is commonly given to the technologies that use successive layers of material to create a three dimensional object

Product Design Guides

Engineering Product Design Guides are intended to guide and inform engineering product designers of both theoretical and practical knowledge on various product designs

Metal forming

Metal is plastically deformed to create shapes by a force that exceeds the material yield strength where strain hardening occurs.

Manufacturing Processes

Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product

Mechanical Elements

Mechanical or machine element are basic mechanical parts used as building blocks in mechanical product design such as mechanical transmission components, springs, seals and fasteners.

Design for Manufacture and Assembly

Design for Manufacture and assembly is the combination of two methodologies; Design for Manufacture and Design for Assembly
