Plastic Injection Molding 101 - Determining the Cost of a Mold

One of the most common questions for those looking to source a plastic injection molder is “How much will a plastic injection mold cost?” It's one of the most important questions, since the actual mold represents the most significant expense in upfront production costs. That being said, many factors go into determining the full cost.  With any custom injection molding project, your injection molder should be able to give you the final price tag. In this article, we will review the variables that can impact the cost so that you can be better informed when making a mold purchasing decision. 

The Merits of Building a Mold in the U.S. 

The Rodon Group has been in this business long enough to have worked with, or attempted to work with, molds that were created in Asia (most often, China). Many of these molds are not built to meet strict tolerances, since they don’t have to be. As labor costs rise in China, this no longer becomes an affordable manufacturing process. In addition, molds made in other countries are made from lesser quality steel or aluminum. Again, this causes quality issues and shortens the life of the mold.  Most high-production molders in this country use only the best stainless steel available for the mold base and cavities.  They utilize the latest technology in CNC machining and have seasoned tool makers who know how to create molds that meet the highest performance standards.  When sourcing companies, be sure to look for U.S. based manufacturers.

Injection Molds 101: Cold Runner vs. Hot Runner Molds

Ever since its introduction in the late 19th century, plastic injection molding has revolutionized the way we create plastic products. Although the technology has evolved significantly over the years, many injection molds today still fall into two main categories: hot runner and cold runner systems. Each of these systems has their own benefits and limitations which make them better suited for specific applications.

Understanding the differences between these technologies can help you have a more productive and informed discussion with your plastic injection specialist to determine the most feasible option for your unique application.
