特點(diǎn)： 1、模頭能360左右旋轉(zhuǎn)，可增強(qiáng)塑料薄膜的強(qiáng)度和均勻度。 2、螺桿、料筒均采用38CRMOALA合金鋼，經(jīng)氮化處理和緊密加工而成，硬度高，耐腐蝕性強(qiáng)，經(jīng)久耐用。 3、模頭鍍硬鉻，其結(jié)構(gòu)為螺旋芯軸式，擠出的熔料均勻，吹制的薄膜光潔度好；風(fēng)冷裝置結(jié)構(gòu)為迷宮型，出風(fēng)量均勻，采用循環(huán)水冷卻，從而使吹制的薄膜達(dá)到最佳的透明度。 4、卷取裝置采用壓力摩擦收卷或中心收卷，采用力矩電機(jī)調(diào)節(jié)，收卷平整，換卷方便。 Use: The machine is suitable for producing PP. it is widely be used for packing food, garment, textile, daily necessaries and industrial product etc. Characteristics:

• 1.       Die head can be turned 360°, it can strengthen the tension and evenness degree of film.
• 2.       Screw stem and cylinder are all made of 38CRMOALA alloy, and treated by nitrogen. It has an advantage of great thickness, corrosion resistance and endurance etc.
• 3.       Die head has been chromized, it’s advantage of screw core structure, melting material extruding evenly, and blowing film smoothly etc. cooling equipment is a labyrinth blow pump which has good effect. Especially, it adopts the recycling cooling water system to ensure the best transparent effect.
• 4.       Discharging equipment adopts pressing braking winding equipment& central winding equipment, and it adopts torque motor to adjust, has the merits of smooth film, convenience operation.
