核心特点 / Key Features

中文：

• 单螺杆挤出结构：结构简洁、操作方便、维护成本低，适合中小规模薄膜生产
• 合金钢螺杆料筒：38CRMOALA合金钢经氮化处理与精密加工，硬度高、耐腐蚀性强
• 螺旋芯轴式模头：镀硬铬处理，熔融料挤出均匀，薄膜光洁度好
• 迷宫型风冷装置：出风量均匀，薄膜冷却效果稳定
• 水平往复摆动牵引：取代模头旋转，避免漏料与密封问题，消除膜卷大小头、松紧边缺陷
• EPS光电纠偏系统：自动纠偏导向，确保收卷整齐
• 灵活收卷方式：压力摩擦收卷或中心收卷，力矩电机调节，收卷平整、换卷方便
• 温控范围明确：LLDPE/LDPE加工温度160–180℃，HDPE加工温度210–230℃

English:

• Single-screw extrusion structure: Simple structure, easy operation, low maintenance cost, suitable for small-to-medium scale film production
• Alloy steel screw and barrel: 38CRMOALA alloy steel with nitriding treatment and precision machining for high hardness and strong corrosion resistance
• Spiral mandrel die head: Hard chrome plated for uniform melt extrusion and smooth film surface
• Labyrinth-type air cooling: Even air distribution for stable film cooling
• Horizontal reciprocating oscillating haul-off: Replaces rotating die head, eliminating leakage and sealing issues, and overcoming uneven roll ends and loose/tight edge defects
• EPS photoelectric deviation correction: Automatic deviation correction and guiding for neat winding
• Flexible winding options: Pressure friction winding or center winding with torque motor adjustment for flat rolls and easy changeover
• Clear temperature ranges: LLDPE/LDPE processing at 160–180℃, HDPE at 210–230℃
