High-volume refurbishment factories, used-phone wholesalers processing large lots, and operations that include larger tablet screens need more than a desktop polisher. A 16-station or 24-station screen polishing line turns cosmetic screen restoration from a bench task into batch production. This page explains how to choose between CITEE’s CPM-016 16-Station Polishing Machine and CPM-024 24-Station Polishing Machine and how a multi-station line integrates into a refurbishment workflow.
16 stations vs 24 stations
- CPM-016 16-Station Polishing Machine (16 stations): the standard factory configuration for batch processing phones and Apple Watch-scale devices across a defined monthly volume, with a manageable footprint and staffing profile.
- CPM-024 24-Station Polishing Machine (24 stations): the high-capacity line for the largest monthly lots, peak-season throughput, and when larger tablet/iPad-sized work is included in the same operation.
The right choice depends on your monthly qualified volume, shift pattern, device mix and floor space — not maximum capacity alone. A correctly sized line keeps every station fed; an oversized one wastes capital. Send your monthly volume and model mix for a sizing recommendation.
Where polishing fits the factory line
- Intake & triage: grade units; send functional-but-scratched displays to polishing, cracked/faulty units to replacement.
- Waterproofing: seal with UV Waterproof Sealing Glue and model-specific Phone Holding / Waterproof Molds (manual or dispenser).
- Batch polishing: load 16 or 24 devices per cycle with cerium-oxide slurry and water circulation.
- Cleaning & inspection: remove seals, inspect first-pass finish.
- Re-coat: apply Oleophobic Anti-Fingerprint Coating to restore the oil-resistant surface.
- Re-grade & pack: units move to the higher cosmetic grade.
Running a multi-station line economically
- Consumables as a supply contract: plan blankets, rollers and powder by monthly volume with safety stock for the fastest-turning items. See the consumables guide.
- Mold library: hold molds for every supported model; new iPhone/Android generations usually require additions.
- Standard work: fixed powder ratio, sealing SOP and replacement schedule protect first-pass yield — the main driver of margin. ROI logic is on the refurbishment ROI page.
- Installation: confirm power/voltage, water supply/drainage and floor layout before delivery; we advise overseas buyers on setup.
OEM/ODM and supply for volume buyers
CITEE supplies refurbishment operations directly and supports OEM/ODM branding, custom mold sets, machine-and-consumables bundles, and container-scale orders. For branded alternatives such as REFOX APM-class units, see the machine comparison page.
