In this section, you will learn how to optimize your designs for injection molding. Use the following guidelines to save time and reduce failures and learn how to create features that maximize the functionality of your designs.
Even though quality control is typically performed after a full production run, performing rigorous testing on a small batch of initial samples can help to optimize the molding much faster. By thoroughly testing the sample output before expending the resources required for a full production run, it’s easier to fix problems while the stakes are still low.
In order to achieve a properly optimized injection molding process, the mold must work in concert with every material in the design. Key factors like the melting temperature of the materials, the temperature tolerance of the mold, and each material’s viscosity all play an equal part in producing the perfect finished product.
To adequately evaluate the mold’s viability, all of the following tests should be used:
After the tests above have generated an adequate amount of data, it’s much easier to make the subtle tweaks and adjustments that are needed to optimize the injection molding. If there were some issues with erratic fill times or inconsistent temperatures during the testing, for example, then now is the time to dial in the results.
Each part of the process has its own set of acceptable parameters, and it’s best to make sure that everything is in range before a major production run. If anything is even the slightest bit off, this can compromise the entire molding process.
Furthermore, it’s worth the effort to further optimize parameters that fall within their accepted range. Additional testing can pay dividends, especially if it’s possible to identify the small changes that have disproportionate rewards.
Even the most magnificent injection molding process in the world is all but worthless if it isn’t repeatable. Documenting everything in the process will help the team troubleshoot if things go sideways, and proper documentation makes sure that everybody can get on the same page without wasting time.
A suitable protocol will have a detailed list of:
With a properly documented protocol, team members can also identify the exact source of any problem much faster.
Optimizing the process of injection molding services requires a proactive approach and meticulous attention to detail. With carefully tested parameters, proper documentation, and a dedicated team, it’s possible to prevent the vast majority of unforced errors and extraneous expenses before they have a chance to occur.
