Our door sash assemblies are manufactured to the precision fit and finish requirements of our customers. The sash assemblies produce vehicle door frames that are lighter and stronger, as well as offering corner welding and metal finish that meets the stringent surface appearance requirements.
The door sash fabrication begins with the shaping of flat steel through our roll forming process. We form complex cross sections through this process and then apply spot weld patterns required for the structural integrity of the part. After roll forming, the product is sent to our assembly process, where the part contour is formed on a 3-dimensional numerical controlled bender. This process assures a precise fit to the vehicle body.
The parts then move through a series of robotic welding and metal finishing applications. This advanced assembly process ensures every part meets the strict requirements of our customers.
