Battery Manufacturing EquipmentDouble-layer wide-web extrusion coater
HAONENG's double-layer wide-web extrusion coater applies two material layers to the same face of the substrate. HAONENG lists coat-weight and CCD feedback, areal-density and defect inspection, slurry and drying monitoring, Siemens bus control and MES linkage.
By HAONENG
Two layers on the same face
HAONENG's page says the machine can lay two different materials, one over the other, on a single face of the substrate. That is what defines it, and it differs from coating both faces. Ask for a drawing of the layer order and web path that shows the feeds, coating heads and drying arrangement.
Listed features include coat-weight gauge feedback to the head, CCD dimensional feedback, Siemens bus control and MES linkage. The monitoring list covers X/β-ray areal density, dimensional and defect inspection, NG marking, infrared electrode temperature, slurry flow, viscosity and temperature, and cathode NMP concentration or anode oven humidity.
The page gives no width or speed figures for acceptance. Ask which instruments and control loops are fitted to the quoted version, how each layer is assessed and what an out-of-limit reading changes in the process.
| Parameter | Published value | Record status |
|---|---|---|
| Layer arrangement | Two material layers can be coated on the same substrate face | known |
| Quality feedback | Coating-weight and CCD dimension closed-loop controls | known |
| Drying monitoring | Cathode NMP concentration; anode oven humidity | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Trace a defect to its place on the roll
Ask for one worked example that links a detected defect to its roll position, the NG mark and the downstream record. Agree calibration, sampling resolution and alarm handling for each instrument. The control-bus brand tells you nothing about which data fields reach your plant, so ask for the field list.
Send both slurry formulations, the layer loadings, the substrate and your drying needs. Agree the usable coating width and the trial conditions before comparing this machine with a single-layer or two-sided process.

Check how the coater responds to a layer adjustment
Write separate targets for each layer and for the combined dry coating. Name the measurement points and sampling method so that each profile can be tied to its own layer, since a total thickness reading hides how the two layers split. Ask which readings drive the feedback function and which stay as offline laboratory tests.
With HAONENG's agreement, make a deliberate adjustment and watch how the coating profile responds. Log the starting state, the change, the settling time and the usable web that follows, and agree any response-time figure in writing. Count start-up and shutdown material in the loss record. Ask for calibration and maintenance instructions for the sensors and actuators supplied. Use the results as part of acceptance for the closed-loop function on your two same-face layers.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the layer arrangement match the electrode? | The page describes two layers on one face of the substrate. | Confirm the head diagram and each layer's wet and dry targets. |
| How is thickness feedback accepted? | The page lists coat-weight feedback but no measurement points or correction limits. | Check recorded profiles and the correction response on your recipe. |
Equipment questions
Are both faces coated by this reference?
HAONENG describes two layers on the same face. If you also need both faces coated, ask HAONENG to show the process arrangement for that in the offer.
Source s2Does standard drafting prove MES compatibility?
No. Ask for the machine's interface specification and supported records, and plan an integration test with your plant system.
