公司名称：南京国塑挤出装备有限公司

特点：螺杆采用渐变型单螺杆设计，专门针对聚乳酸，玉米淀粉熔融设计，同时针对材料的特殊性可开排气，立三辊压延成型，辊筒温度通过模温机可调出来的产品保证不糊料，产品成型表面色泽度好，韧性好，厚度采用千分表定位，收卷采用自动张力卷取。
Features: The screw adopts the gradient type single screw design, which is specially designed for the polylactic acid and corn starch melting. At the same time, it can be opened and vented according to the speciality of the material. The three-roll calendering is formed, and the temperature of the roller can be adjusted by the mold temperature machine. No paste, the product molding surface has good color, good toughness, the thickness is measured by the dial gauge, and the winding is automatically tensioned.

工艺原理：PLA料玉米淀粉料→单螺杆挤出机：原料融熔塑化→ 快换过滤网→挤出模头成型挤出 → 立三辊压光机 → 冷却定型装置→ 切边机构→牵引传送→ 自动张力收卷
Process principle: PLA corn starch material → single screw extruder: raw material melt plasticization → quick change filter → extrusion die forming extrusion → vertical three roll calender → cooling setting device → trimming mechanism → traction Transfer → automatic tension windin
