Pumps, Motors, Valves & Cylinders


We specialize in the service of hydraulic components for plastic injection molding machines. Because many of these machines are manufactured overseas lead times for components can be months. By stocking and repairing components in North America we cut lead time in half and have customers back in production faster.

Many older model machines utilize components no longer available from the original equipment manufacturer. To tackle this problem we keep a stock of re-manufactured parts and repair these aging components to extend the life span of your assets. We have the knowledge to restore your components to OEM specification.

All types of hydraulic cylinders are rebuilt in house. Older cylinders with OEN seal kits are not a problem. Our custom sealing solutions make unusual seals and sizing a non-issue.
