Description

How do I choose between Firstcut and Protomold services? When should I use machining versus injection molding? Before making the investment to have injection-mold tooling made or high-volume machining processes, you likely will want to test a part that is as close to the production part as possible. Firstcut CNC Machining is the best option for this situation. Additionally, engineers often need just one or maybe a few parts for test fixtures, assembly jigs or assembly fixtures. Machining is the best option here as well, but traditional machine shops often charge a significant non-recurring engineering (NRE) charge for programming and fixturing. This NRE charge often makes getting very small quantities not affordable. The automated Firstcut prototype process eliminates the upfront NRE costs and is able to offer quantities as low as one part at an affordable price and get parts in your hands in one to three days. Protomold Injection Molding is better suited to support prototyping that needs larger amounts of samples for functional or market testing, bridge tooling or low-volume production.
