Urethane Stop Blocks – Custom Molded Blocks!

Urethane stop blocks are designed to absorb an impact and stop a cable or chain in the desired location. Urethane is an ideal choice of material as it will return to its original size even after years of abuse in any working environment. Molded urethane stop blocks and parts are designed by our engineers from our in-house machine shop from an AutoCAD. We apply different molding design operations utilizing compression molding and rotational force for the manufacture of our molded polyurethane parts.

Opencast molds are the most common and are typically made from aluminum that consists of many pieces and parts; this ensures the finished product, are high performance and tight tolerance molded polyurethane parts. Urethane stop blocks do not need to have a set “block” profile as well. Any custom profile to fit the application can be molded at a rapid fast for high volume at Plan Tech. We stock a large variety of special additives which we add to improve the physical properties of our molded urethane stop blocks and custom parts. All of our molded urethane stop blocks and custom polyurethane parts possess the ability to return to their original shape after absorbing high impact, and they retain this ability even after they have repeatedly been abused for years.
