Capsule filling machine

The choice depends on your production scale. Manual machines are suitable for R&D or small pharmacies (up to 2,000 caps/hour). Semi-automatic machines require an operator for capsule loading but automate the filling and closing, ideal for medium batches. Fully automatic machines (NJP series) are essential for industrial-scale production, offering speeds from 30,000 to 450,000 capsules per hour with minimal human intervention.

Prioritize machines with PLC control systems (like Siemens or Delta) and touch-screen interfaces for precision. Ensure the machine supports the specific capsule sizes (00#, 0#, 1#, 2#, 3#, 4#) you intend to use; many suppliers offer interchangeable mold sets. Check the filling accuracy error margin, which should be less than ±3% for powders and pellets to ensure dosage consistency.

The equipment must strictly adhere to GMP (Good Manufacturing Practice) standards. Look for 304 or 316L stainless steel construction for all contact parts to prevent contamination and ensure easy cleaning. For export to Europe or the US, verify CE Certification and UL-listed electrical components to meet safety and quality regulations.

Different materials require specific feeding mechanisms. Fine powders may need an auger feeder or a vacuum loader to prevent dusting, while granules or pellets require a gravity-fed system to avoid breakage. If filling oily or sticky substances, ensure the machine features a specialized dosing disk and scrapers to maintain high yield and prevent clogging.

Always send your material samples (powder/pellets) and empty capsules to the manufacturer for a FAT (Factory Acceptance Test) before final shipment. Request a video of the machine running your specific product at the rated speed to confirm filling success rates and sealing integrity.

Due to the precision of the internal cams and indexing units, ensure the machine is packed in a vacuum-sealed plastic wrap inside a fumigated solid wooden crate to prevent rust and mechanical shock. Negotiate for overseas installation services or detailed video installation guides, and confirm the availability of wear-and-tear spare parts (like springs and seals) for the first 2 years of operation.

Utilize secure payment methods and prioritize suppliers on Made-in-China.com who have undergone on-site audits by third-party agencies (like SGS or TÜV Rheinland). Look for 'Diamond' or 'Gold' member status to ensure you are dealing with an established manufacturer rather than a small trading company.
