introduction：Electric forklift market Manual stacker is used more in China、Diesel forklift truck、Electric forklift truck（Divided into full electric forklift and semi-electric forklift），They all have a stacking function。Compared with manual stackers and internal combustion forklifts，They occupy a larger market than electric forklifts，Electric forklifts should be accepted by the market，It will take some time。However, there is no doubt that electric forklifts are a major trend in the development of future stackers，This is determined by the concept of environmental protection and energy saving，Nowadays, the concept of environmental protection and energy saving is advocated all over the world。When Japans Honda invaded the American car market，As well

introduction：It can be filled in almost all thermoplastics20％～30％（Mass fraction）Or more glass fibers to prepare glass fiber reinforced plastics（FRTPorGFTP），A wide range of applications。FRTPThe injection molding with its substrate（unreinforced）Compare with，It has the following characteristics： （1）FRTP The fluidity of the resin is worse than that of the unreinforced resin，So the barrel temperature at the time of processing、Mold temperature、The injection pressure is generally higher than that of unreinforced resin。 （2）For the same reason，Its mold mainstream way、Diversion channel、The size of the inner gate should be larger than that of the unreinforced resin。 （3）FRTPProduct surface
