An OEM Truck Door Manufacturer contacted Hi Tech Extrusions in an effort to optimize a complex manufacturing process.   The revolutionary process created by Hi Tech Extrusions replaces a two-part side seal door assembly that consisted of aluminum and EPDM. The EPDM material had a high coefficient of friction that wore out the seals prematurely and marred the door. Hi-Tech Extrusions developed a Co-extrusion side seal that simply clips into place speeding up installation time and reducing the coefficient of friction, both of which improves our customer’s profitability.
