When it comes to designing plastic components it is a complex task entailing numerous factors that tackle application needs. How will the component be utilized? How does it suit other assembly parts? What loads will it go through in use? Besides the structural and functional issues, processing problems play a vital role in the injection molding prototyping design. How the plastic enters, loads, and cools inside the cavity to take shape of the part largely dictates what shape the features in the part should take. Sticking to some essential injection molded part design rules will give rise to a part that can be much robust in service, besides being easier to produce and assemble.
Considerations to make
Prior to trying to make a part through injection molding, you need to consider certain things:
To prepare a product for molded manufacturing you need to make a huge investment. Ensure that you comprehend this essential pointer upfront.
You need to decide the number of elements manufactured at which the molding process turns out to be the cost-effective procedure of manufacturing. You need to ascertain the number of elements manufactured at which you anticipate breaking even on the investment. Take into account the costs of testing, design, production, marketing, assembly, and distribution and the anticipated sale price points].
You need to design the element right day one keeping injection molding prototyping in mind. Making geometry simpler and reducing the number of elements near the beginning will pay great dividends in the later stage.
Ensure to design the tool to avoid defects during manufacturing. Take into account gate locations and operate simulations utilizing the software.
The major benefit of injection molding prototyping is the power to scale production altogether. After paying the initial costs, the price per unit is low during the injection molding production process. It might drop drastically when you produce more parts.
