Our company has developed a new type of high-speed fully automatic plastic bidirectional stretching geogrid production line (model: TJ-TGGS4000). This high-speed geogrid production line integrates the production essence of renowned geogrid enterprises over many years and the advanced plastic extrusion layering patented technology. It has been meticulously optimized by renowned extrusion machine experts and based on Tongji's years of experience in producing plastic net materials equipment. It is a high-speed fully automatic geogrid production line developed and manufactured by our company! The production line speed reaches 16 meters per minute, which is more than twice the production speed of traditional models and leads the market in terms of geogrid production speed at present.
