Protecting High-Value, Low-Volume Components
Aerospace components such as turbine blades, actuators, and avionics carry unit values in the tens of thousands of euros, so a single failure is an expensive event for the program. Rulowin designs PP trays with CNC-cut ESD foam inserts that hold tolerance-critical parts at a static-dissipative surface resistance of 10 to the 6 to 9 ohms for safety.
The conductive shell prevents electrostatic discharge that can silently degrade sensitive electronics long before a functional test would reveal the damage to a flight-critical board. That protection is why aerospace buyers treat ESD control as non-negotiable in the spec and will reject a container that cannot demonstrate the correct surface resistance with a calibrated meter during incoming inspection at the receiving bay.
Traceability for AS9100 Compliance
MRO operations require documented chain of custody for every serialized part that moves through the shop, because an airworthy component must be traceable to its source. We integrate laser-etched part numbers and QR plates that survive the solvent cleaning used in aerospace wash lines without the marking fading or lifting off the wall of the case over time.
Each container maps to a maintenance record, supporting AS9100 traceability audits without paper travelers that tear, smudge, or get separated from the component they describe during a busy shift on the floor. The digital link also lets the planner see at a glance which jobs are waiting on which parts, which improves scheduling accuracy across the whole maintenance line and reduces aircraft-on-ground time for the operator.
Lightweighting for Air Freight Savings
When parts move by air, every kilogram costs money on the airway bill and adds to the fuel burned on the flight. A PP honeycomb case weighs 40 percent less than an aluminum equivalent with equal protection, trimming air freight on a Paris to Singapore lane by an observed 310 EUR per shipment of sensitive avionics that must travel quickly to keep a fleet flying.
The smooth surface also resists fuel and hydraulic fluid, simplifying decontamination before the case returns to the loop and is reused for the next high-value movement across the network. That chemical resistance means a spill during handling does not write off the container, which keeps the per-trip cost low enough to make air freight of spares economically sensible for the airline’s maintenance operation.
Durability in Harsh Hangar Conditions
Hangars swing from minus 30 to plus 50 Celsius, and equipment is dropped, dragged, and stacked under time pressure to turn an aircraft around. Polypropylene keeps its impact strength down to minus 20, and our copolymer grade extends that to minus 30, so cases do not crack during winter ramp handling in northern bases where the temperature drops sharply overnight.
A 5-year service life is typical with monthly inspection, which is far longer than the one-way foam and wood crates aerospace once relied upon for these sensitive shipments. The durability also reduces the administrative load of ordering and tracking disposable packaging, freeing the logistics clerk to focus on the parts themselves rather than the boxes that carry them from bay to bay.
