Custom shells, covers and panels. Developed around the assembly, the service conditions and the requirements your project has to meet.
A removable UAV cover, a cabin trim panel and a ground-equipment housing should not share a generic specification. The installation determines what needs to be reviewed.
Review the shell with its frame, batteries, wiring and service openings. The outside shape is only part of the brief: a cover also needs to come off without disturbing the equipment beneath it.
Review togetherFixing locations, removal direction, ventilation openings and clearance around moving components.
Discuss the installed position, visible seams, finish and cleaning routine before choosing a sheet. For regulated applications, establish the required qualification route before committing to tooling.
Review togetherFinished material configuration, attachment details and the evidence required by the responsible approval team.
Equipment used on the ground has its own demands: handling knocks, outdoor exposure and repeated maintenance. Review the enclosure around the actual equipment and the way operators use it.
Review togetherAccess, panel support, drainage, cleaning chemicals and the required impact performance.
These are application areas for manufacturing review, not blanket approval for aircraft use. Supplier eligibility and part acceptance must be confirmed for the specific program.
A shell can look right on the bench and still be difficult to fit or service. These are the questions worth answering with the frame and the sample in front of you.
Show us the mating assembly—not only the outside of the cover.
Before tightening the fasteners, place the cover on its intended supports. Does it sit naturally? If a seam only closes when a screw is tightened, compare the frame, trim edge and fixing position before changing the whole shell. The joint needs a clear locating arrangement, not just a smaller tolerance on every dimension.
A useful sample check: record the gap before and after fastening, using the same assembly and sequence.
A thinner starting sheet is not the only decision. Drawing the sheet over the tool redistributes its thickness; corners and deeper features need attention. Identify the areas that need stiffness or fixing support, then inspect those locations on the formed sample. Do not accept a part on its total weight alone.
Mark the measurement locations on the drawing so the next sample is checked in the same places.
Loosening a screw is only the start. Can the screw withdraw? Can the cover lift clear without pulling a cable or catching the next panel? After servicing, can it return to the same locating features? A useful review includes removal and refitting with representative connectors and wiring in place.
For a frequently opened UAV hatch, show the normal service action—not only a photograph with the hatch already removed.
An opening for ventilation, a sensor or a connector is not just a trim outline. Ask what sits behind it, what the edge can obstruct and where water can travel when the equipment is used outdoors. Any sealing, cooling or sensor-performance requirement needs its own assembly-level check; the shell drawing alone cannot establish it.
A familiar material name is not a complete specification. Agree the exact grade, thickness, finish and applicable requirements before making a production commitment.
Compare candidate sheets against the actual use: temperature, sunlight, handling impact and chemical exposure. Availability, forming behaviour and the finished part’s stiffness also matter.
Have the responsible design or approval team define the applicable requirements and test configuration. A sheet supplier’s report is supporting evidence—not automatic approval of the finished component.
Scope matters: this page does not offer airworthiness approval, flight-critical structural design or an AS9100 certification claim. If your purchasing specification requires a particular approval or certification, confirm supplier eligibility with us before proceeding.
“The fit is not right” starts a conversation. A marked location, the assembly condition and a clear photograph make it possible to discuss what should change—and what should stay unchanged.
If a hole is difficult to align, first establish the drawing revision, locating surfaces and assembly condition. Moving the hole may help one sample while leaving the underlying mismatch unresolved. A proposed change should say which interface it addresses and whether neighbouring parts are affected.
Identify the sample revision and mark the locations under discussion. When a sample is revised, repeat the same fit or access check rather than relying on memory. Before repeat supply, agree which drawing, finish reference and inspection criteria define the accepted configuration.
Not by itself. Check whether the report covers the required grade, thickness and configuration, then confirm the remaining evidence with your program’s responsible approval team. Do this before a material substitution or finish change.
It is a useful starting point, but not a direct manufacturing conversion. Solid bosses, undercuts, return edges and a uniform CAD wall may need different solutions in sheet thermoforming. Share the assembly as well as the printed part model.
A dimensioned sketch, application photographs and an approximate quantity can start the discussion. Tooling cost, tolerances and timing need a clearer specification before they can be confirmed.
State that requirement at the start and request current certification evidence before supplier selection. Do not treat a general quality certificate or this application page as proof of aerospace qualification.
Start with the part and the decisions that are still open. We can discuss the manufacturing questions before a tooling proposal is prepared.
