When designing a part that will be produced by machining, careful consideration needs to be given to the application to ensure that all the performance requirements will be addressed in the part design. While machining is a forgiving process in that part designs can be easily changed, since the tooling costs required to produce a design are eliminated (as they are not with injection molding, for example), it still makes sense to get the part design right before production commences. In this blog we offer a checklist of considerations that should be taken into account as a part is designed.

Machined plastic parts: checklist of design considerations

The following checklist consists of categories of factors relating to application that should be reviewed when designing a plastic part that will be produced by machining. These factors are critical for ensuring that the part design and material selection are appropriate for the application conditions that will be encountered.

Category 1: Service conditions

Category 2: Tolerancing

Category 3: Other considerations

Using this checklist together with material data sheets, it is possible to create a short-list of candidate materials that qualify as being suitable to meet the design considerations. Reputable suppliers of machined plastic parts will also be able to offer expert guidance that can help ensure that the optimal material is chosen to support the design considerations.
