2200T Backward Extrusion Production Line
Backward extrusion, also known as indirect extrusion, offers reduced extrusion load, high extrusion speed, and allows for processing longer metal billet; The billet being extruded features a cross section that is uniform over the entire length of the metal extrusion.
RH Group is capable to offer aluminum profiles undergone various surface treatment services, including polishing, drawing, anodizing, electroplating, sand blasting, dusting, etc. Different treatment services are optional according to different circumstances with different industries, humidities and PH values.
RH Group has 130 precision cutting machines, wire-cut discharge machines and 270 CNC machine tools, allowing strong precision processing capacity for various customized precision parts, such as aerospace aluminum parts, automotive parts, laboratory apparatus parts, medical equipment parts, etc.
In our R&D center which was built in 2012, there are 5 expert researchers who have worked in the fields of casting, mold, extrusion, heat treatment and quality analysis for years.
