KS07.04 – PU INJECTION MACHINES
System for processing polyurethane by injection. The polyol and isocyanate are mixed by the injection screw before being pushed inside the mould. Can be adopted for the direct injection of soles on the upper.
1, Suitable for direct soling injection of single PU or colorful PU.
2, Each injection unit is equipped with two colors with accurate measurement of painting.
3, Automatic cleaning
4, Low noise and low energy consumption
5, Hold threaded rod with spring collect to gain precise positioning, reliable operation and convenient replacement.
6, Speedy running of threaded rod to optimize mixture of raw materials.
7, Advanced mechanical structure guarantees the strict synchronization of opening and closing valves so as to ensure the quality of soles.
8, High-accuracy of metering pump and advanced converter technique make sure the precision of metering.
9, Storage silo, equipped with advanced liquid level sensor is able to tell the how much raw material left in the tank at any time, to facilitate the production.
injection rate 50cm3/s
injection pressure 600bar
screw speed 30-250rpm
1, Sound mechanical formation and module design make installation more convenient and structure more reasonable.
2, Stable rotation and accurate positioning.
3, High mold clamping force.
4, Automatic location of shoe last
5, Independent PLC control for each station with multi-function.
6, Simple operation
7, A machine can produce soles from different raw material.
mold holders 24/30
last height 333/430/530mm
mold size 430*200mm
mold clamping force of lower part 75KN
Travel of lower part 40mm
1, Suitable for direct soling injection of single density rubber sole, PU midsole and RB outsole as well as double density rubber sole.
2, Sizing material is injected prior to vulcanization to shorten the time.
3, By adopting of rexroth hydraulic components and the closed loop control system for pressure and flow rate. Have 40%-80% energy saved compared to traditional models, low operating noise and low temperature rise of hydraulic oil.
4, Computer controlled temperature during plastics melting with its precision of up to ±1°C.
5, With oversea magneto-strictive displacement transducer, to ensure more accurate metering and displacement.
6, Sole injection with open-ended mold make the production more convenient and practical.
injection rate 28cm3/s
injection pressure 600bar
screw speed 30-250rpm
1, Applicable for direct soling injection of whole TPU sole or PU midsole and TPU outsole.
