Traditional Sand Cores and Molds
With over 50 years of experience in the foundry industry, Humtown Products is equipped in the manufacturing, packaging and delivery of sand cores and molds.
Humtown initially was established as a pattern shop in 1959. Pattern making – once the domain of uniquely skilled artisans working exclusively in wood – is an invaluable part of Humtown’s heritage. Today, our craftsmen produce patterns using conventional methods and the latest technology.
The UNItube System solves many problems commonly encountered in production core making. Misalignment of the core machine at the squeeze-blow position can often cause severe damage to an unyielding metal tube or the core box. Metal blow tubes, with their rigid construction and inflexibility, can cause damage to the core box if misaligned. The UNItube System absorbs greater misalignment stress due to its unique high-impact plastic design.
The UNIplug has a thicker wall that allows for the installation of a core vent for gassing or tamping tube.
