Monroe Mold specializes in extrusion blow molds with special expertise in polyethylene applications. Our customers represent key segments of the packaging industry as well as commercial and industrial markets. We offer unit and production mold development and in-house sampling. From product development and design to complete in-field mold startup, we are your one-stop manufacturer.

Monroe Mold’s engineering department uses a combination of the latest 2D and 3D software for all blow mold design work. From the initial product design to the final mold, we can provide detailed information in a format that is most compatible with your current software. We have experience in designing blow molds for various machine platforms and configurations and can incorporate any specific mold standards that you may have.
Our engineers use a strict set of standards developed and refined from our 30+ years of blow mold and tool design. This is the “Monroe Mold Way” and it guarantees that every project is built to the exact same level of quality.

Our plastic mold makers average over 15 years of experience. We have a stringent apprenticeship program that ensures the highest level of craftsmanship and quality in the mold making industry. The Monroe Mold staff takes a team- approach to every blow mold making job that goes through our shop. Each new job is assigned a job leader and a team; they are responsible for the job from the beginning all the way to the finished product. This results in smoother workflow and eliminates the “bottlenecks” associated with individual departments. This provides back-up and a diversified skills base, which helps reduce any chances for miscommunication that might be caused from passing the job from department to department.
