FRP product surface finish depends on fiberglass mold finish Xinjiang works for Curb mold, so their quality fiberglass mold, depending on the surface treatment. Curb fiberglass mold is new products, market acceptance is very high on the fiberglass mold some more effort, you'll get better results the use of glass fiber reinforced cement products on. Highlights fiberglass mold surface treatment technology to master very much: 1, Water Mill. New mold or old mold renovation, first with water sandpaper mill Xinjiang works for Curb mold, when water mill sandpaper starting point must be high, generally starting from 600 # Xinjiang works for Curb mold, some users in order to improve efficiency, even from 400 # 400 # The following more water sandpaper rough start, faster at immediate, not knowing the future marks coarse sandpaper grit fine sandpaper, whether caused by sanding and then also can not afford to wear; they wanted 800 # 600 #, 1000 #, 1200 #, # 1500 (or even 2000 #) step by step, of which should not be spared, but also to Seiko secret agents, are willing to make great efforts to spend fine effort and does not allow opportunistic. Some die in the state of repeated heating and cooling during operation, so that the cavity surface tension, the pressure becomes stress, causing surface cracking and spalling, increasing friction, hinder plastic deformation Xinjiang works for Curb mold, reducing the dimensional accuracy, resulting in failure of the die. Therefore, the mold material to have resistance to thermal fatigue performance. When the mold into a higher operating temperature, hardness and strength will decline, leading to early galling or plastic deformation and failure. Thus, the mold material should have high resistance to tempering stability, to ensure the mold at the operating temperature, high hardness and strength. To prevent mold parts suddenly brittle fracture at work, the mold should have a high strength and toughness. Mold toughness depends mainly on the carbon content of the material, grain size and organization status. Shaanxi Curb mold, shaped Curb mold, mold provided by Cheng Cheng Cheng Cheng Qingyuan County wangzhuang plants die.
