When custom injection molding is done without a prototype parts stage, this generally leads to a series of production tool adjustments that are both disruptive and costly. Some production managers misperceive a saving to be made for skipping prototype tooling, but those quickly evaporate with the higher risk of a defective part causes legal expenses and other related costs.
Depending on the complexity of the application, prototype parts generally account for about 20-40% of overall production tooling costs. It’s not a small investment, but it’s well worth it when you consider these top three advantages.
Testing Different Plastic Materials
Any plastics made can be more efficiently performance-tested and comparisons assessed without a large financial investment. Having the benefit of physically evaluating prototype parts is a major advantage in making a final selection.
Confirming Part Geometry Feasibility
This is the best opportunity to see if the prototype parts perform properly without defects. If there are problems, it is somewhat simple to revise the prototype tool with cuts or welds.
Reducing Production Time
Overall, it is faster and less costly to make changes to prototype parts compared to the production parts. The ability to design, create, and revise prototype tools is a competitive advantage in the industry. It can lead to a final design that needs fewer revisions to the production tool, saving time and money on the project’s production end.
