In the matter due to mold plastic fill and flow are exposed to greater stress and friction, requiring precision molds link shape and dimensional accuracy of the stability of the cover mold box, guarantee adequate use of mold life. Die wear resistance depends on steel and chemical factors heat punishment hardness, thereby increasing the hardness of the mold will help improve the wear resistance. What conditions and Die die die differences cable trench cover mold box, in addition to being definitely pressure, but also suffer temperature. To do this requires the selection of the steel material fewer impurities, uniform fine structure, no fiber bias, there should not be pitting or orange peel-like defect during polishing. Many people think that the more severe the mold, the better, of course, the desire to buy a good mold for each buyer. Not so? And how to distinguish the relationship between weight and mass? Of course, the quality of cover mold is indeed linked to weight but conversely, the weight is not necessarily a good big cover mold, why? The answer in the recycling rainwater cover mold boxes, crushed recycled material back process, after crushing always remains with the grout powder Order cover mold box, the same steel injection molding, the products will only be made out of heavy, not light present, this complicated economic situation for the development of our country slope protection brick mold provides a development platform for the cover mold boxes, rain cover mold boxes, Li Chen mold (certified merchants) provided by the city is the county Li Chen plastic mold factory.
