Characteristics and advantages of the STAVAX Sweden wins Bystronic mirror plastic mold steel 
 ⒈ STAVAX ESR advanced stainless steel mold steel, have the following characteristics: 
 Excellent corrosion resistance; excellent polishing; excellent wear resistance; good machining properties; heat dimensional stability. 
 ⒉ the above advantages, making the steel has excellent production characteristics. Because of its excellent corrosion resistance, plastic mold, the following advantages: 
 ⑴ low maintenance costs 
 Mold after long-term service, the cavity surface is still maintaining its original state. Mold in the humid environment, store or use, no special protection. 
 ⒉ low production costs 
 Mold cooling water of Road and less susceptible to corrosion (unlike the ordinary mold steel), heat conduction properties, the cooling efficiency remains stable in the mold of the entire service cycle, ensuring consistent mold cycle time. 
 The above advantages combine STAVAX ESR, high wear resistance, low maintenance costs and the high life of the mold, to achieve best value for money.
