Our PU Insole Pouring Production Line represents a complete
fullyautomatic continuous manufacturing solution specially
engineered for massvolume production of polyurethane shoe insoles.
With over 20 years of shoemachinery research, manufacturing and
export experience since 2007, KingKung devotes itself to developing
reliable highefficiency equipment for global footwear
manufacturers. This integrated production line combines PU pouring
station, longsection heating curing oven, rotary moldplate
conveying system and central electric control cabinet into one
unified workflow. It drastically cuts manual intervention,
stabilizes product consistency and helps shoe factories raise
output while controlling overall production costs. The whole unit
is widely applied for producing sport shoe insoles, comfort casual
insoles, antifatigue workshoe insoles and various functional PU
foam insoles.
The overall dimension of the complete assembly line is 25m * 2.3m *
1.6m. It is equipped with a 22meter long heating oven, and each
oven section measures 20001100900mm. The oven maximum power reaches
70KW, and the builtin oven fan motor runs at 0.37KW. Advanced
hotair circulating design distributes heat evenly inside the entire
oven chamber. Uniform temperature environment is critical for PU
foaming and curing process; it effectively prevents common defects
such as partial foaming, surface air bubbles, uneven hardness and
product deformation. Even under nonstop longshift factory
operation, the oven maintains steady thermal performance and avoids
temperature fluctuation which may cause large batches of defective
insoles.
For power and motion control, this production line adopts wellknown
Delta servo drive system, and the drive motor power is 5.5KW.
Cooperating with highprecision PLC and intuitive touchscreen
humanmachine interface, operators can conveniently adjust conveyor
running speed, oven zone temperature, timing parameters and
production logic on screen. Complex professional background is not
required for daily operation. The conveying system is fitted with
48 sets of doublelayer mold plates. Each mold plate dimension is
1000mm500mm6mm. Doublelayer structural design greatly improves
space utilization and daily production capacity. By simply
replacing different mould inserts, manufacturers are able to
produce PU insoles in diverse sizes, thicknesses, patterns and
functional styles to satisfy different market demands.
Mechanical durability and antiwear performance are fully considered
for heavyduty continuous factory operation. The chain and chain
groove adopt standard 4mmthick chain and 4mmthick chain track. The
travelling wheels are solid iron wheels embedded with 304 stainless
steel bearings, and the wheel track thickness is 5mm. These
heavyduty configurations reduce friction loss, lower noise and
extend service life under repeated cyclic movement. The whole
supporting framework is built with nationalstandard 4080 channel
steel with material thickness ranging from 3.5mm to 4.0mm. The
connecting rod uses nationalstandard 4060 square tube with 2.0mm
wall thickness. Robust steelwelded structure resists bending and
deformation under longterm fullload working conditions, which helps
customers reduce spareparts replacement frequency and lower
laterstage maintenance expenditure.
The standard rated working condition is 380V / 50HZ. Customized
voltage and frequency options are available to match powersupply
standards from different countries and regions. The machine
supports CE certification to satisfy export compliance requirements
for overseas shoemaking plants.
The whole manufacturing workflow covers PU rawmaterial feeding,
automatic metering & pouring, hightemperature foaming, thermal
curing, and finishedinsole discharging. All core procedures are
completed on this onestop production line. Compared with semimanual
equipment, this continuoustype line greatly lifts daily production
volume, decreases labor input and keeps reject rate at a low level.
It is an ideal upgrade choice for mediumsized and largescale shoe
insole manufacturing factories.
KingKung provides comprehensive presales and aftersales technical
support for this production line. Our engineering team can supply
layout drawing suggestion, installation guidance, onsite or remote
operation training, and longterm technical consultation.
Nonstandard customization is acceptable: we can adjust oven length,
moldplate quantity, line total length and layout according to your
factory workshop space and output target. You are welcome to
contact us for detailed quotation, machine running test video,
technical parameter sheet and further business communication.
