Wax Injection and Mold Assemblies

Princeton Tool has supported the investment casting industry for more than 23 years. The wax patterns and mold assembly business unit services major foundries across the United States of America providing alternatives to injecting and preparing waxes in house. This allows you to keep valuable floorspace previously supporting the many steps of producing wax molds, and re-allocating that space to increase throughput by enhancing dip lines, mold storage, and furnaces.
