Once a part is molded, most plastic parts require additional processing for completion. Many plastics finishing processes are performed for appearances purposes or aesthetics, such as surface finishing. Surface finish can be used to give an injected molded part a certain look, feel, or texture. The surface finish can be a critical factor in either the appearance or performance of your product as it serves both a cosmetic and functional purpose.

Establishing a uniform wall is one of the most important decisions an engineer makes when designing a plastic part. The nominal wall influences the overall dimensions of the part, the part performance, and the manufacturing requirements. Proper wall thickness is just one of the key design elements that must be held to a high standard for the injection molding process to work properly. This article discusses the importance of maintaining uniform wall thickness as well as the drawbacks of not being able to maintain this design feature.
