SJ-40*2*28FM450*2 film blowing machine

Performance and Characteristics: 1.The screw uses the most advanced alloy treatment technique and precision finishing, which hardness is higher. the corrosion ability is better,the life is 2 and 3 times longer than the screw by nitrided. 2. The screw ratio (L/D) is bigger, plastic ability is stronger, the temperature distribution is even, automatically controls tepmerature, automatically controls temperature, the blown plastic film is bright and even, the operational performance is good. 3. The draw gear is integrated which could adjust raise and fall automatically. 4. Adopt advanced frequency conversion, high energy efficiency. 5. There are several types of winder for choice. 6.Set the die rotary device according to the customer’s requirement. 7.Scientifically designed, the machine set has two extruders and heads with such advantagesas increasing production capacity,saving energy,worker and workshop area, etc.Main Technical data ModelSJ-40×2×28FM450×2SJ-45×2×28FM450×2Screw diameter40mm×245mm×2Screw ratio28:128:1Max output20---50kg/h20---50kg/hPower of main motor15kw18.5kwMax fold width of film400mm400m
