14、流動等原因，GMT制品中玻纖的分布不均勻，尤其在薄壁處或邊角處玻纖含量低，導(dǎo)致局部強(qiáng)度不夠。而通常邊角處需要打孔裝配，需要做后處理。 采用LFT-G顆粒料進(jìn)行注塑成型加工，由于注塑模具比模壓模具具有更高的精確度和設(shè)計(jì)自由度，可以加工前端組件、儀表板骨架等結(jié)構(gòu)復(fù)雜有多個(gè)嵌件或孔位的部件。生產(chǎn)效率高，材料浪費(fèi)少。 采用LFT-D在線直接模壓成型，成型周期一般不超過60秒，而且省去儲存、運(yùn)輸費(fèi)用，原材料成本低，生產(chǎn)效率高。 由于綜合成本降低，歐洲北美市場出現(xiàn)GMT下降而LFT上升的趨勢。,,LFT與GMT的對比,,廣州金發(fā)科技股份有限公司,Long Fibre Reinforced Thermopl
