Large castings, resin sand, vanished die forging real, single reach more than 40 tons. They are made of high-quality fine gray cast iron HT200-HT300, precise ratio, the higher flexural tensile strength, so you worry-free purchase. International popular heat treatment process, the casting stress and deformation reduced to the minimum degree. Persistent use tends to be more constant. Large long machining, milling can be boring. For example, a 2 x 8 meters gantry milling, planer bed (bed reach 16 m overall length), two forging dividends to cast, can be divided into roughing twice, but when finished, you can join them Forging about to fade away with the production of the machine bed and other large mold have great advantages compared to traditional sand, it not only eliminates the need for expensive wood-based costs, and ease of operation, shortening the production cycle, improve the production efficiency, dimensional accuracy high, allowance, good surface quality and other advantages. Large castings Botou class manufacturer, excellent service and good quality first industry Tools Co., Ltd. Hebei have more flagship product: cast iron platform, cast iron plate, inspection plate, crossed plate, welding flat, boring and milling machine table, wharve workbench, assembly site with a plate, large gantry milling machine table, sheet metal platform, cast iron square box, machine plate, engine dynamometer test stand, all kinds of power machinery test station (also known as the trough of iron or Leong, and track); a combination of assembled T-slot plate, coordinate instrument plate, mold plate, boring and milling machine table, laboratory base plate, flat-foot, bridge type flat feet, feet, square box, machine horn V-iron, V-frame, granite slab (Flat Rock) and other rock measuring tool. While a resin sand casting, solid casting, high grade cast, to undertake large-scale castings, non-standard products according to customer requirements!
