PU Casting
NEXAMS Leading the Way in PU Casting for Precision Components and Low-Volume Plastic Manufacturing
PU casting, also known as polyurethane casting, is a highly versatile plastic manufacturing process used to create durable, flexible, and precision-engineered components. At NEXAMS, we work alongside trusted Vendors and reliable Suppliers to provide industries with Support that ensures every PU cast part meets tight tolerances and complex geometries. Our decision to collaborate with local and nearby Manufacturers allows us to deliver human-centered solutions through efficient, low- to medium-volume production runs guided by ethical practices.
The process begins with creating a master pattern, often via CNC machining or 3D printing, followed by silicone mold production. Liquid polyurethane resin is poured into the mold, cured, and post-processed. Our Support teams help Suppliers and Vendors optimize these workflows. By integrating CNC machining with PU casting, we give nearby Manufacturers a cost-effective path to achieve injection-molding-quality parts without the investment in metal tooling. This ethical approach to engineering empowers local businesses with agile manufacturing capabilities.
Whether you’re exploring vacuum casting for prototyping or transitioning to production with PU casting low pressure casting, NEXAMS and our extended network of Suppliers and Vendors provide consistency, quality, and thoughtful Support. We work closely with nearby fabrication teams to ensure timely delivery and ethical communication throughout the entire PU casting manufacturing process.
