There is a complete production line of resin sand, machine tools and other machine tool castings are used resin sand, EPC casting. This process makes casting high dimensional accuracy, uniform, no buckets, cast no flash, burr ;Surface smoothness close to precision casting, the internal structure of stability, to exclude or reduce the trachoma, air and other casting defects, the entire production process three environmental protection, no pollution.

Drilling machine table casting EPC wear resistance and good shock absorption.As the graphite graphite in cast iron is conducive to lubrication and oil storage, so good wear resistance.Similarly, because the presence of graphite is better than the shock absorption of steel.

Drilling table process performance : Since the gray cast iron has a high carbon content and is close to the eutectic composition, the melting point is low, the fluidity is good, and the shrinkage rate is small, so that it is suitable for casting complicated structures or thin-walled castings. Further, since graphite is easy to form during cutting Broken chips, so the gray cast iron machinability is better than steel.

Using high-quality cast iron ht250-300, face hardness hb170-240.Casting after two artificial aging treatment, removal of internal stress. Casting the internal structure of stability, not easy to deformation.

Lost Foam Casting is to combine the foam model with the foam shape to form the model cluster, brush the refractory paint and dry it, embed it in the dry quartz sand and shake it, pour it under the negative pressure to vaporize the model, The metal occupies the position of the mold, and the casting is cooled by solidification to form a new casting method.

Yongjun measuring machinery factory specializing in the production of a variety of machine tool castings, cast iron platform V-shaped V-shaped frame, square box square tube, shaped castings, road pier, welcome to inquire!
