In manufacturing, it’s always a good idea to understand the best practices for the process you intend to use to create a part — whether it’s plastic molding, 3D printing, CNC machining or beyond. Best practices exist for every process, and they have been developed for a reason: they can help ensure the quality of your product; they can make your production process more efficient; and, overall, they can save you significant time and money throughout your development and ongoing production processes.
Comparing the benefits and drawbacks of two different manufacturing processes can be one of the best ways to illustrate the importance of proper process selection for a project. Urethane casting vs. plastic injection molding, for instance — two processes that are, on the surface, relatively similar — can yield vastly different results depending on your requirements and expectations. To start, let’s look at the difference between casting and molding.
