About ChengPak
ChengPak is dedicated to providing precision small-dose automatic filling solutions for CDMOs, biopharmaceutical companies, and specialty pharmaceutical manufacturers. We focus on designing and manufacturing filling equipment for liquids, powders, and capsules—especially for 0.1–10 mL (or equivalent small formats), multiple formats, and frequent change-over production scenarios.
From the very beginning, our mission has been to solve a core industry challenge: how to transition from R&D/trial production to commercial-scale manufacturing without sacrificing precision or over-investing in equipment. Our machines are engineered for high accuracy (±0.5-1 %), fast change-over, small batch flexibility, and full compliance with GMP and clean-room requirements.
We serve process engineers, packaging managers, and production leads across:
CDMOs: supporting efficient, small-batch, multi-client production lines;
Biopharmaceuticals / Vaccine manufacturers: handling liquids, suspensions, lyophilized powders in small doses;
Specialty Pharma / Nutraceutical / Aesthetics: automatic capsule, powder and liquid （vials, syringe, cartridge, eye drop）filling for small batch, high-spec production.
We provide:
Small-dose liquid and powder filling systems (0.1–10 mL or equivalent)
Automatic capsule filling machines with quick format change capability
End-to-end services: from solution design, machine selection, layout, to validation (IQ/OQ/PQ), installation, commissioning, training, and global after-sales support
At ChengPak, we believe that when production volumes are small but the requirements are high, choosing the right filling equipment is key. Let us help you transition smoothly from R&D to commercialization with confidence in small-dose production.
