Battery Manufacturing EquipmentSingle-Layer Slot-Die Electrode Coater
HONBRO's Single-Layer Slot-Die Electrode Coater feeds, unwinds, coats, guides, dries and rewinds electrode foil. It runs at 1–50 m/min with continuous, intermittent or strip patterns, lists ±1% areal-density error and ±0.5 mm length and registration, and offers roll-change, gauge and heating options.

Process sequence, patterns and listed tolerances
HONBRO describes the sequence as feeding, unwinding, coating, guiding, drying and rewinding. It lists continuous, intermittent and strip patterns. Speed runs from 1–50 m/min. Areal-density error is within ±1%, and coating length and front-to-back registration each have their own ±0.5 mm entry.
Each tolerance measures a different result. Before comparing them with another coater's precision figures, agree the pattern, slurry, sampling position and operating window. Ask how a pattern change is set up and how startup coating is kept apart from accepted material.
The width entry reads 100–1000 with no unit. Ask for a dimensioned drawing and a confirmed usable coating width. Options include automatic roll change, solvent-concentration and thickness monitoring, and different heating arrangements; have each one listed in the quote.
| Parameter | Published value | Record status |
|---|---|---|
| Web speed | 1..50 m/min | known |
| Areal-density tolerance | ±1% | known |
| Coating patterns | Continuous, intermittent and strip | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Settle the dryer and the inspection package
State the electrode chemistry, solvent and loading, then pick the dryer arrangement to be quoted. Ask which heating supply and exhaust connections you must provide. If you buy online inspection, find out which reading adjusts the coating and what data is stored with the roll number.
For intermittent coating, ask for sample measurements across start and stop edges and for registration. Results on continuous coating may differ from those on another pattern, so test each pattern you plan to run.

What to ask Aohong for
The name-change notice explains the move from Hongbao to Aohong, and the product page describes the standard configuration. Ask for a coating trial on your material, the current quoted width, the scope of any certificates and acceptance terms for your electrode.

Turn the quotation into a defined delivery
Ask for a marked process drawing showing the unwinder, coating head, oven zones, web guides, tension-control zones and rewinder. Attach an inclusion list so every option and every service you supply has a named owner. A product-family page starts the conversation; the drawing and list fix which head, pumps and drying set-up you will receive.
In the sample trial, note the pattern and coated dimensions, measure the agreed coating-weight profile and keep rejected sections labelled with the reason. Separate set-up losses from steady production and record the settings needed to return to the recipe. At handover, the documents should name the current contracting entity and include manuals and the spare-parts arrangement. Check each named station against the delivered package.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Is the width entry usable? | The table gives 100–1000 with no unit. | Ask for a dimensioned drawing with units and the usable coating width. |
| Who supplies the complete package? | The brand is HONBRO and the company name has changed from Hongbao to Aohong. | Confirm the contracting party and who supplies the coating head, oven and commissioning. |
Equipment questions
Why is there no numerical coating width in the parameter panel?
The catalogue table gives 100–1000 with no unit. Ask HONBRO for the usable coating width in millimetres on a dimensioned drawing.
Source s2Can an old Hongbao document be accepted under the new name?
The public notice links the two names. Check each document's issuer, validity and the equipment it covers, and ask Aohong to confirm in writing that it applies today.
