Battery Manufacturing EquipmentTMAX-300-H400 Heated Electrode Roller Press
The TMAX-300-H400 is a heated roll-to-roll electrode calender with 300 mm diameter rollers on a 400 mm face. Usable pressing width is up to 300 mm. Oil-heated solid rollers, a servo roll gap and matched unwinding and rewinding make it a fit for pilot lines and electrode density trials.

TMAX-300-H400: 300 mm of usable width on a 400 mm roller face
The press uses 300 mm diameter rollers with a 400 mm roller face, and TMAX sets the effective use width at no more than 300 mm. Plan your electrode width and pressing setup from the 300 mm figure.
The solid rollers are heated by circulating oil from an external temperature-control unit. A servo drive sets the roll gap, and separate units handle unwinding and rewinding. TMAX gives one radial-runout figure measured on a grinder and another for the installed machine; these were taken under different conditions. Electrode thickness spread is best judged by measuring pressed electrode.
The specification also covers tension control, roll-changing access and installation conditions. Ask for a layout that shows incoming and outgoing rolls and maintenance clearance as well as the press frame. Check the roll-size limits and utilities against the handling equipment you already have.

Setting up a heated rolling trial
Send coated foil with its incoming thickness, loading and the target output thickness or density. Agree where thickness is measured across and along the web, and whether readings are taken hot or after a set cooling time. Ask for roll temperature logs and the time needed to reach a stable running condition.
The catalogue's gap-adjustment precision describes the mechanism. In the trial, link gap, pressure, tension and temperature to measured electrode results. Count start-up scrap separately from stable running when you judge usable output.

Documents to collect with the quote
A university laboratory paper mentions a TMAX hot roller, without naming this press model. The company page shows older certification labels, so ask which certificates are current and whether they cover the quoted configuration. Also collect current safety documents, the calibration scope and the electrode acceptance results from your trial.

Accepting the press on your own electrode
The University of Chicago supporting document reports that a TMAX vertical hot roller was used to prepare film. It gives no model number and no acceptance figures for this 300 mm usable-width press, so plan your own acceptance figures for this machine.
For this purchase, agree the incoming electrode condition, target density and thickness, sampling points across the usable width, and how start-up and roll-change material is counted. Ask TMAX to record the installed configuration and heating settings alongside the trial results. Accept the press by comparing the pressed web with those agreed targets.
The TMAX profile lists the coaters and mixers that usually feed this press in a laboratory line, and the electrode drying page explains why pressed rolls are vacuum-dried again before assembly.
Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the electrode fit the working width? | The roller face is 400 mm; the effective use width is at most 300 mm. | Send coated-web width, edge margins and target electrode thickness. |
| Is heated rolling part of the quote? | Heating uses circulating oil from an external temperature-control unit. | Ask for the heating package offered and trial density and thickness results. |
Equipment questions
Can a 400 mm electrode be pressed because the roll is 400 mm wide?
No. The effective width is at most 300 mm. For a wider electrode, ask TMAX for a separate configuration with its own drawing and specification.
Source s2Does a precise roll-gap setting guarantee the electrode thickness?
The gap setting tells you how finely the rolls adjust. Final thickness comes from a material trial with an agreed sampling method at your chosen temperature, pressure and web tension.
