Vital Variables Affecting Plastic Injection Mold Costs

If you intend to calculate the cost of plastic injection molding, it helps to recognize the fact that the price stated on the quote is not the only important consideration. Basically, look at the purchase price on top of the enduring costs that will begin to take effect once the mold is deployed and continue being felt during the mold’s remaining life. Several parameters have a bearing on these two elements of your mold’s general costs.

The purchase price of an injection mold will be dictated by the variables below:

Component Size and Design
The Beginners Guide To Products (Getting Started 101)

The creation of large components requires large molds, and ultimately higher material costs. In the same vein, an elaborate part design calls for an elaborate tool design, which basically keeps the costs higher. In contrast, components that require uncomplicated design do well with less complex mold designs, resulting in lower equipment costs.
5 Uses For Options

Plastic Type Selection

A more expensive tool may be necessary for handling particular types of plastics. For instance, higher tool costs are expected with material that’s unstable, corrosive, or has mineral, glass, carbon fiber, or other corrosive materials. The same is true for materials that need high mold temperatures. Additionally, maintenance costs for the mold may be affected by the parameters in the long run.

Component Tolerance Strategy

If tight tolerance is required for parts being produced, there’s the need for additional mold manufacturing steps. In the end, there will be higher costs for maintenance as well as manufacture.

Yearly Volumes

In case you’re acquiring it for high-throughput projects (in the sense of hours, rather than number of components), you’ll require an excellent quality mold to deliver consistent service, which results in higher costs, certainly. A mold with a higher number of cavities is also linked to higher manufacturing costs.

Cycle Time Needs

When fast tool cycles are preferred, there’s need for consistent cooling throughout the entire cavity impression, or in each cavity in the case of multi-cavity molds. To accomplish this, excellent tooling design and superior build are necessary, both which contribute to increased tool machining costs, and maintenance costs in certain scenarios.

Source Country

The cost and quality you can get in your plastic injection mold depends on where it’s manufactured. An example is cost of injection molding in China, which may be lower than other places. However, consider quality as you evaluate the cost of domestic against outsourced plastic injection molding. To be safe from the complications that lower-cost machines may have, it helps to reach a fair compromise as you carefully weigh cost, quality, and your exact needs.
