Pharmaceutical Filling and Capping Machines
Cap Coder designs and manufactures pharmaceutical filling machines, bottle filling machines and capping
machines for UK and international pharmaceutical, nutraceutical and life sciences manufacturers. Every
line is specified against your product, your container, your cleanroom classification and your GMP documentation requirements before a single component is selected.
What a Pharmaceutical Company Needs to Specify Before Buying a Filling or Capping Machine
Specifying a pharmaceutical filling machine, bottle filling machine or capping machine is not the same exercise as specifying general industrial packaging equipment. The machine has to be justified inside a quality management system, validated against a User Requirement Specification (URS), and supported by documentation an MHRA inspector can review. The requirements below are the ones a UK pharmaceutical buyer should have answers to, or should expect their machine supplier to ask about, before a quotation can be considered complete.
Product and container characteristics
- Product viscosity, foaming tendency, shear sensitivity and presence of particulates or suspended actives
- Fill volume range and required accuracy tolerance, typically expressed as a percentage or fixed volume deviation
- Container type and material: glass or HDPE/PET bottles, vials, or unit-dose containers, including neck finish and tolerance
- Cap type: screw cap, snap cap, tamper-evident closure, or child-resistant closure tested to ISO 8317
- Whether the product is light-sensitive, oxygen-sensitive, or requires nitrogen or inert gas dosing at fill
Regulatory and data integrity requirements
- Compliance with the UK Supply of Machinery (Safety) Regulations 2008 and UKCA marking of the finished machine
- Electronic records and audit trail functionality aligned with EU GMP Annex 11 expectations, where the machine holds recipe or batch data
- DSEAR/UKEX assessment and ATEX-rated components where the product or cleaning solvents present a flammable atmosphere risk
- Serialisation and aggregation capability to support Falsified Medicines Directive obligations, including 2D data matrix printing and verification at the line
- Change control documentation for any modification made to a validated machine after qualification
Throughput and line integration
- Required output in units per minute or per shift, and whether this needs to be sustained or is a peak figure
- Format changeover requirements if more than one container or cap size runs on the same line, and acceptable changeover time
- Upstream and downstream integration: bottle unscrambling, labelling, induction sealing, cartoning, serialisation and palletising
- Available floor space, ceiling height and services (compressed air quality, electrical supply, extraction) within the cleanroom envelope
- Whether the line needs to run semi-automatically now with a defined path to full automation as volumes grow
Cleanroom and GMP classification
- Required cleanroom grade for the filling zone, typically ISO 14644-1 Class 7 or 8 (broadly equivalent to EU GMP Grade C or D) for non-sterile oral and topical liquids
- Whether the product requires aseptic or terminally sterilised processing, which raises the cleanroom and machine specification to Grade A/B standards
- Product contact parts specified in 316L stainless steel or validated pharmaceutical-grade polymers
- CIP (clean-in-place) and SIP (sterilise-in-place) capability, or a defined manual strip-clean and revalidation procedure between batches
- Airflow, differential pressure and particle count requirements at the machine interface with the cleanroom
Validation and documentation
- A written User Requirement Specification (URS) agreed between quality, production engineering and the supplier before design work begins
- Design Qualification (DQ) confirming the proposed machine meets the URS
- Factory Acceptance Testing (FAT) at the supplier’s site, followed by Site Acceptance Testing (SAT) after installation
- Installation and Operational Qualification (IQ/OQ) protocols, and Performance Qualification (PQ) using the actual product and containers
- Calibration certificates for all metrology-relevant components, traceable to UKAS or an equivalent national standard
Commercial and lifecycle support
- Lead time from purchase order to FAT, and realistic installation and validation timelines
- Availability of spare parts, wear part schedules and UK-based service and calibration support
- Operator training provision and the technical documentation pack supplied with the machine, including the Declaration of Conformity
- Warranty terms and the supplier’s track record with pharmaceutical and regulated manufacturers specifically
- Whether the supplier can support future requalification if the product, container or cap changes
The Cap Coder Range
Cap Coder has manufactured filling and capping machinery in the UK since 1976. The current range, from the Sigma Fill through to the Mini Mono, is built and specified to serve pharmaceutical, nutraceutical and cosmetics manufacturers who need documented, GMP-compatible equipment rather than repurposed industrial packaging lines.
Pharmaceutical liquid filling machines
Volumetric and net-weight filling heads specified against the viscosity, foaming behaviour and fill accuracy tolerance of the product, with product contact parts available in 316L stainless steel for cleanability and chemical compatibility with liquid pharmaceutical and nutraceutical formulations.
Pharmaceutical bottle filling machines
Bottle filling machines configured for glass and HDPE/PET containers across the volume ranges typical of oral liquid, topical and nutraceutical products, with changeover parts engineered for defined format-to-format switchover times.
Pharmaceutical capping machines
Chuck cappers and snap cappers set up to deliver consistent, repeatable torque, reducing the cross-threading and seal failures that create rejected batches, with tamper-evident and child-resistant closure handling available where the product requires it.
Cleanroom-ready builds
Machines built for integration into ISO 14644-1 classified cleanroom environments, with construction and surface finishes chosen to support the cleaning and environmental monitoring regime of the cleanroom grade the product requires.
GMP documentation and validation support
Support through the URS, FAT and SAT process, with documentation packs structured to feed directly into customer IQ/OQ/PQ protocols, so the machine arrives with the paper trail a quality department and an MHRA inspector expect to see. Read our whitepaper.
Semi-automatic to fully automatic pathways
Lines specified so that a pharmaceutical manufacturer can start on a semi-automatic filling and capping setup and move to full automation as volumes grow, without discarding the qualification work already completed on core components.
Pharmaceutical FAQs
GENERAL ANSWER
Most non-sterile oral and topical liquid products are filled in an environment broadly equivalent to EU GMP Grade C or D, classified under ISO 14644-1 as Class 7 or 8. Sterile products require Grade A/B conditions and a validated aseptic process.
CAP CODER’S APPROACH
The required cleanroom grade is established with the buyer’s quality team before the machine is specified, so the construction, surface finish and cleaning regime of the filler and capper match the classification the room is validated to.
GENERAL ANSWER
Most bottle filling machines can be built with interchangeable format parts to run more than one container or cap size, though changeover time and revalidation requirements after a format change need to be agreed at the specification stage.
CAP CODER’S APPROACH
Format changeover requirements, including target changeover time, are captured in the URS so the machine is built with the correct changeover parts and tooling from the outset.
GENERAL ANSWER
Timelines vary with machine complexity and cleanroom readiness, but manufacturers should plan for build and FAT, installation and SAT, and then IQ/OQ/PQ, as three distinct phases rather than a single handover date.
CAP CODER’S APPROACH
Lead time and a realistic FAT date are agreed at order stage, with SAT and validation support scheduled around the customer’s own cleanroom and production availability.
GENERAL ANSWER
At minimum, a Declaration of Conformity, technical file, calibration certificates and a documentation pack sufficient to support the buyer’s own IQ/OQ/PQ protocols. Machines handling electronic batch data should support audit trail functionality consistent with EU GMP Annex 11.
CAP CODER’S APPROACH
Documentation is structured during the FAT and SAT process specifically so it can be dropped into a customer’s IQ/OQ/PQ protocols without being reformatted or chased up after delivery.
GENERAL ANSWER
Where filling and capping are combined on a single line, validation typically covers the line as a whole, but capping torque and seal integrity are usually qualified as a distinct performance parameter within the PQ protocol.
CAP CODER’S APPROACH
Capping torque consistency is set and demonstrated at FAT using the actual cap and container combination, so seal integrity data is available before the machine leaves the factory.
