Product Description 1.Slot die: This is the core component of the coating system, with an adjustable narrow outlet gap. The coating liquid is evenly distributed and coated onto the moving substrate through this gap under a certain pressure. According to the process requirements, the slit die can be divided into fixed and adjustable types2.Liquid supply system: including storage tank, agitator, filter, and high-precision metering pump, used to provide stable coating liquid without bubbles and impurities3.Unwinding/rewinding system: using tension control mechanism to ensure that the substrate maintains constant tension during operation, avoiding wrinkles or stretching deformation4.Drive system: Servo motor drives the drum to achieve high-speed and smooth operation of the substrate5.Drying system: multi-stage hot air circulation oven with temperature zoning control function, ensuring fast and uniform curing of the coating6.Control system: adopts PLC+touch screen human-machine interface, supporting functions such as parameter setting, fault alarm, data recording, etcMachine Parameters Maximum gluing width3450 mmMold width range400mm-3500mmGlue viscosity rangebelow 30000cps(containing 30000 cps)Solid content of the coating solution1%-100%Coating wet coating amount10μm-225μm(single-layer slit mold head)Working speedMax.150m/minDetailed PhotosPhotes of Slot-die Extrusion Coating UnitPhotos of packaging and shipmentOur Machine Advantages 1.Closed-loop precision glue application system ensures uniform coating distribution with a consistency of 1%-2%. 2.Slot-die extrusion head manufactured under constant-temperature conditions using specialized processing techniques, with quality verified via 3D coordinate measurement. 3.Slot-die head constructed from imported 17-4PH stainless steel, subjected to multi-stage heat treatment for long-term dimensional stability. Includes precision stainless steel shims tailored to customer product requirements. 4.The slot-die head and backing roller incorporate an integrated vacuum chamber system,PTFE anti-adhesion treatment on all interior surfaces,PTFE edge sealing for airtight operation,High-performance vacuum blower,Hybrid piping system combining stainless steel hardlines with flexible hoses,Streamlined aesthetic design. 5.Precision micro-adjustment mechanism:Mechanical fine-tuning system with 0.001mm resolution; 6.Rapid head positioning system:Linear guide sliding + pneumatic actuation for quick approach/retraction,Positioning repeatability ≤0.005mm 7.The coating backing roller meets ≤0.002mm specifications for circular runout, straightness, and concentricity. 8.Slot-die unit frame construction:Heavy-gauge solid steel plates,Precision machined with stress-relief heat treatment,Nickel-electroplated corrosion-resistant surface.Company Profile
