Camozzi Automation and HAYLEY DEXIS designed, manufactured, and dispatched a bespoke pneumatic cylinder on the day a critical loader failed at a UK pharmaceutical manufacturing facility.
After the overnight failure stopped production equipment, the site found that no replacement cylinder was held locally and that the original equipment manufacturer required an 18-day lead time. Maintenance personnel completed a temporary repair, but the damaged component remained vulnerable to another stoppage.
Using an available cylinder drawing, HAYLEY DEXIS asked Camozzi’s UK engineering team to assess whether a replacement could be produced locally. Minor design changes were agreed before manufacture began through the supplier’s express cylinder service, allowing the completed unit to leave the factory later that day.
Installed by 7pm, the cylinder enabled the loader to return to operation by 9pm. The companies estimate that a full 18-day shutdown would have caused approximately £4.3 million in lost production, based on the value attributed to the interrupted manufacturing process.
Because the equipment operated within a regulated pharmaceutical facility, restoring movement was only one part of the recovery. Dimensions, materials, installation, engineering changes, and return to service needed to be recorded through the site’s maintenance, quality, and change control procedures.
Component criticality outweighs purchase value
Manufacturing plants commonly stock motors, bearings, valves, sensors, and other frequently replaced parts, while bespoke cylinders and machine specific assemblies are harder to justify as inventory. They may fail rarely, occupy storage space, or become obsolete before use, making their cost appear avoidable until production stops.
Pharmaceutical operations create additional exposure because a breakdown can affect more than machine availability. Depending on the process, an interruption may alter material condition, cleaning status, environmental control, batch records, or work already completed, requiring inspection or disposal before production resumes.
A useful criticality assessment must therefore examine the complete operational consequence of failure. A relatively inexpensive actuator may control a loader, isolator, transfer unit, or packaging stage connected to several upstream and downstream processes, allowing one mechanical fault to interrupt a much larger production system.
Local engineering capacity offers an alternative where holding every spare is impractical. A nearby manufacturer can review the original design, select suitable materials, and produce a replacement without waiting for an overseas production slot, although rapid manufacture depends on accurate drawings and operating information being available before the breakdown.
Equipment data consequently needs the same discipline as physical inventory. Plants often discover during an emergency that drawings are incomplete, stored in obsolete formats, or controlled by a supplier that no longer supports the machine. Recording component geometry, interfaces, loads, stroke, pressure, sensing, and environmental requirements during planned maintenance reduces dependence on hurried reverse engineering.
Some low demand spares can be retained as approved digital designs rather than finished stock, but the file alone does not constitute a replacement part. Material availability, seals, coatings, machining, assembly, testing, and regulatory approval still determine whether a component can be reproduced quickly and accepted for service.
Pneumatic cylinders that share similar external dimensions may behave differently under load. Rod diameter, bearings, seals, cushioning, mounting geometry, corrosion protection, and sensor positions influence reliability, while a substitution based only on envelope size may create excessive wear or unexpected movement.
Temporary repairs also require carefully defined limits. A component restored sufficiently to run for several hours may remain at risk of leakage, contamination, sudden failure, or damage to surrounding equipment. Continued production protects output, but only while the condition is monitored and a permanent repair progresses without delay.
The same-day response relied on a functioning relationship between the manufacturer, distributor, and pharmaceutical site. Drawings, design decisions, production capacity, technical approval, logistics, installation, and return to operation were completed within hours rather than being negotiated after several days of escalation.
Replicating that performance requires preparation outside the emergency. Manufacturers need to identify components capable of stopping high value processes, determine which should be stocked, and establish a credible local production route for parts whose cost or obsolescence makes physical inventory uneconomic.
The replacement cylinder removed an immediate 18-day lead time, but the longer term value lies in the failure information. Reviewing why the original component failed, whether its design or duty had changed, and whether another spare should now be held can prevent the next incident from depending on another exceptional recovery.
