1985年，四位志同道合的好朋友在广东省汕头市成立了汕头市金砂化工厂有限公司，并以此注册“四合”为商标，也意喻本厂产品四时合用。 作为一个拥有20年专业生产食品添加剂和化学试剂的厂家，我厂产品获得越来越多的客户的青睐，为此我们衷心感谢。希望今后能够继续获得您的支持、信任，还有您提出的宝贵意见，以便我们更好地为您服务，使我们能走得更远。
ShanTou JinSha Chemical Plant was established by 4 good friends who have a common goal in ShanTou City GuangDong Province in 1985, meanwhile registered “四合” as trade-mark.
