Mandrel is an important element to ensure the smooth operation
of the extruder, so we will make several tests each combination
of bits in order to ensure to achieve tolerances. Years of
experience in processing so that we can supply to 6 m long
mandrel. 40CrNiMo mandrel made of material at high speed, high
torque, high load, in particular good toughness and mechanical
properties, in the process strictly controlled precision to
ensure the mandrel groove depth, groove from standard
surface smooth, tough and durable. Also based on customer
requirements, providing customers with high wear resistance,
high corrosion resistance of powder high-speed steel and other
specialty steel products. In terms of product categories, the
company in addition to supply domestic manufacturers extruder
accessories, as well as German Werner £ Pfleiderer WP,
Leistritz Germany Rice, Berstorff Germany Berstorff, Toshiba
Toshiba, JSW Steel said in Japan, Kobe, Kobe, Japan, etc. the
company's machines offer standard accessories.
