Cost Analysis: Single Vs Multi-Cavity Molds"

Torn between single and multi-cavity molds? Discover how choosing the right cavitation level can lead to significant cost savings and increased efficiency.

When choosing between single and multi-cavity molds, keep in mind that multi-cavity molds can offer lower machine costs per part. Two-cavity molds can save $64,170 over 5 years with a 2.2-month ROI, while eight-cavity molds may provide $12,500 in savings over the same period. Multi-cavity molds excel in efficiency at high production volumes, impacting cost-effectiveness. Their reduction in cost per cavity is significant, especially with higher cavitation levels. The complexity of your parts and the press size you use are key factors to take into account when deciding on the most suitable cavitation level. Explore how production volume, tooling costs, and efficiency play crucial roles in this analysis.

Cost Comparison Overview

When comparing the costs between single-cavity and multi-cavity molds, the significant reduction in machine cost per part with multi-cavity molds is a compelling factor worth examining. Multi-cavity molds can achieve a machine cost per part as low as $0.018, which is particularly lower than what single-cavity molds offer.

This cost advantage becomes even more pronounced with higher cavitation levels. For instance, a two-cavity mold can lead to savings amounting to $64,170 over a span of 5 years, with a rapid return on investment of 2.2 months compared to a single-cavity mold.

In addition, an eight-cavity mold presents an opportunity for $12,500 in savings over the same period. The injection mold ROI is intricately linked to the annual production volume, as evidenced by the substantial $1,386,390 savings over 5 years that a two-cavity mold can provide at a production rate of 2,500,000 parts per year.
