Accessories

Press accessories decide whether your laminate comes out flat, contamination-free, and dimensionally on-target — or whether you spend the next week chasing wear debris and tension artifacts. This collection groups the consumables and add-on hardware that pair with rolling presses, isostatic presses, tape-casting and slot-die coaters, and pouch / coin cell fixtures. Most items are wear parts or format-specific tooling — picking the right material and geometry up front saves a calendar quarter of debugging.

Items here fall into four practical groups:

• Milling and crushing wear parts — jars, jaws, and liner plates for planetary, vibratory, and jaw-style mills. Material choice is the dominant variable: zirconia (ZrO2) for cathode and graphite R&D where Fe / Cr contamination is unacceptable, alumina (Al2O3) for SOFC / SOEC oxide work, hardened stainless for economical bulk milling where trace metal pickup is tolerable, and agate for soft, gentle grinding. Vacuum-sealed jar variants extend the same selection to oxygen- and moisture-sensitive feedstocks without putting the whole mill into a glovebox.
• Roll-to-roll and rolling-press add-ons — R2R unwind / rewind handling units that manage foil tension and edge alignment through the calender nip, with brushless drives selected for argon-glovebox compatibility.
• Coater consumables — slot-die heads (coat-hanger manifold geometry for uniform cross-web slurry distribution) and adjustable-gap film applicators / doctor blades for tape casting, where micrometer-resolution gate control matters once you start compensating for slurry shrinkage.
• Cell-format fixtures — pouch cell racks, quick-press pouch fixtures, PCB coin-cell clamps, and ultrasonic tab-welding heads. Fixtures use gold-plated, four-wire Kelvin contacts so contact resistance does not contaminate your EIS or rate data; welding heads ship in knurling patterns matched to copper vs aluminum tab stacks.

Choose the wear-part material before you choose the geometry — contamination from the wrong jar lining will not show up until you run XRD or ICP-MS on a finished electrode, and by then the batch is gone. If you are setting up a new pilot line, start with the press or coater itself in Presses or Coaters, then come back here for the matching tooling.
