A design is considered to be the best if it contains fewer parts, use commonly available components, easy to manufacture and is easy to assemble. Also, a smaller bill of material(BOM) simplifies data management for organizations. For designers, design for assembly should be the key driver for any product development. The following blog talks about various tips to create a DoA be its injection molding, machining or 3D printing etc.

Identical parts

Generally, assemblies are created by using identical or symmetrical parts for the ease of manufacturing and assembly. Traditionally, two halves of an electronic housing, one-half bosses with self-tapping holes and the other half with thru-holes for screw mounting. This design will require a separate core cavity for injection molding or two different machined components. If the design is created in such a way that one half could be mounted on top of the duplicate copy, this way you’ll need to design only one-half saving money and time to market. Also, greatly simplifies the assembly process.
