A practical guide to tooling type, ZP capacity by station count, compression force, weight uniformity, GMP and data integrity, and matching ZP-19/35/45 models to output.
Confirm tablet diameter (6-25 mm) and tooling standard before specifying a press. YohoAI ZP machines use Type B/BB/D punches for single and double-layer tablets, with turret configurations matched to tablet size and output.

Across the full ZP range (ZP-5 to ZP-55) output spans 50,000-400,000 tablets/hr, so you can scale from R&D to commercial on one platform.
ZP presses deliver 100-150 kN maximum force with up to 50 kN pre-compression and deep fill to 22 mm. Tablet hardness reaches 15-150 N, handling hard-to-compress and high-density APIs plus multi-layer tablets.
A dual-layer servo feeder achieves +/-1-2% weight variation per USP (down to +/-0.5% with an optional weighbridge). Optional in-line metal detectors and checkweighers automatically reject non-conforming tablets.
Tool-free punch removal with pre-stored compression recipes (200+ on the HMI) keeps product changeover under 30 minutes. This makes mixed-product scheduling practical without long line downtime.
Product-contact surfaces are 316L stainless steel with a mirror-polished die table (Ra <=0.4 um), CIP/WIP compatible. Optional FDA 21 CFR Part 11 provides audit trails, electronic signatures, and user access control for regulated facilities.
Every machine ships with IQ/OQ/PQ protocols, FAT, and EN 10204 3.1/3.2 material certificates. The range scales from ZP-5 (50k/hr) for R&D to ZP-55 (400k/hr) for multi-press commercial lines.
Choose by output and force: ZP-19 for pilot, ZP-35 for high-volume commercial, ZP-45 for maximum throughput and hard-to-compress formulations.
| Model | Stations | Capacity | Tablet size | Best for |
|---|---|---|---|---|
| ZP-19 | 19 | 150k tablets/hr | 6-16 mm | Pilot, niche |
| ZP-35 | 35 | 280k tablets/hr | 6-20 mm | Commercial |
| ZP-45 | 45 | 360k tablets/hr | 6-22 mm | Max throughput |
| ZP GMP | 5-55 | 50k-400k/hr | 6-25 mm | Scalable range |
ZP rotary presses handle tablets 6-25 mm in diameter using Type B/BB/D punches, including single and double-layer tablets. Tablet hardness reaches 15-150 N, covering standard, chewable, and high-density pharmaceutical tablets. The turret configuration is matched to tablet size and output, from R&D lots to full commercial runs.
ZP-19 delivers 150k tablets/hr, ZP-35 reaches 280k/hr, and ZP-45 hits 360k/hr. Across the full ZP range (ZP-5 to ZP-55) output spans 50,000-400,000 tablets/hr, so you can scale from R&D to commercial on one platform. A shift at 280k/hr yields about 6.7 million tablets, so size for peak demand.
Maximum compression force is 100-150 kN with up to 50 kN pre-compression and deep fill to 22 mm. This handles high-density APIs, hard-to-compress formulations, and multi-layer tablet production. Closed-loop servo feedback maintains +/-1% compression force accuracy on both pre-compression and main stations.
A dual-layer servo feeder achieves +/-1-2% weight variation per USP, improving to +/-0.5% with an optional weighbridge. In-line checkweighers and metal detectors automatically reject non-conforming tablets before packaging. This protects both regulatory compliance and the cost of wasted active ingredient.
Yes. Product-contact surfaces are 316L stainless steel with a mirror-polished die table (Ra <=0.4 um), CIP/WIP compatible. Optional FDA 21 CFR Part 11 provides audit trails, electronic signatures, and access control. ZP presses are CE marked, cGMP, and ISO 9001:2015 certified for pharma use.
Tool-free punch removal with 200+ pre-stored compression recipes on the HMI keeps product changeover under 30 minutes, making mixed-product weeks practical without major downtime. Turret and punch change is guided by stored parameters, reducing setup error and operator training time.
Every machine ships with IQ/OQ/PQ protocols, FAT reports, and EN 10204 3.1/3.2 material certificates. P&ID and risk-assessment packages support pharma commissioning, and YohoAI engineers assist with on-site execution so your tablet press passes GMP inspection from the first validated batch.
Yes. The range spans ZP-5 at 50k/hr for R&D, ZP-19/35 for pilot and commercial, up to ZP-55 at 400k/hr for multi-press lines, all on one scalable platform. Shared tooling standards and recipe management let you transfer a formulation to high volume without re-qualifying the process.
