Calculating Costs for Plastic Injection Molds: Domestic vs. Outsourced

In case you’re a procurement manager, you bear the duty to compare estimates from different mold creators with each project. And the task of working out the efficiency of the provided options becomes a breeze when you utilize a plastic injection cost calculator. Normally, quotes by different mold creators may be differ appreciably depending on variables such as designs, prototypes, and model components. Below are parameters based on which estimations for plastic injection mold cost may be made:

Core Material

It makes sense to take the core metal into account. It’s common for certain mold makers to use molds made of aluminum for shorter production cycles. When not acquiring the mold for lasting application, aluminum would do just fine. But when your project needs a mold that will remain useful and efficient for a number of years, aluminum may prove more costly over the long term.


When you consider it, it’s almost obvious that the fewer the cavities on a mold, the less the necessary tool work and time, and the lower the cost. Any skilled mold maker makes optimal application of cavitations to maintain maximum production rates. The general consensus among many molders is that creating one mold for every part is better than making a family mold. With family molds, several cavities are needed for the creation of assorted parts. Family molds are associated with more cases of low quality output, and following their maintenance demands, they have more downtime.

The Mold Base

The mold base is casing, sort of, that holds together each input, cavity, and component in a mold. To approximate the cost of the base, take into account the mold size, type of steel used, and extent of needed customization. A mold base may initially have a standard size, but you may machine it further to achieve custom requirements for your project.

Custom Needs for Core/Cavity

You need your mold customized to your specific project requirements. Your customization options for the system are numerous, for example ejectors and cores placements. Also, the type of steel used in the apparatus will affect costs. An example is a mold that utilizes hardened steel, which costs more to machine, although it lasts longest.

Consider Component Complexity

Complexity of the part has a bearing on the costs of the mold, same way as the number of cavities. Therefore, the surface finish on the final output as well as the needed undercuts shall affect total costs too. Mold complexity, and ultimately costs, are also affected by the requirement for tight tolerances in products.

So, if you’re trying to assess custom plastic molding costs, the above factors should be included in your overall considerations.
