Thick Gauge flame retardant ABS Hoppers in 6 mm – Aerospace Interiors Range

These flame retardant ABS hoppers are thick gauge vacuum formed parts supplied to drawing for aerospace interiors. They are formed from flame retardant ABS sheet at 6 mm, trimmed on 5-axis routers and inspected against the drawing before packing. Buyers choose this route where a metal fabrication is too heavy, or where injection moulding tooling cannot be justified for the volume.

Product specification

Key features

• One piece shell replaces a fabrication, so assembly hours drop
• flame retardant ABS keeps the weight down while stiffness is held through the formed shape
• As formed gloss finish as standard, further finishes on request
• Trimmed on 5-axis routers, so mounting holes and cut outs match the drawing
• Tooling stored against the part number for repeat and spare orders
• food contact declarations available

Typical applications

• galley liners
• stowage bin trays
• lavatory panels
• seat back shells
• hoppers used across general aerospace interiors builds

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. The part cools on a jig so the shape is held while the material stabilises.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

Material: flame retardant ABS

Flame retardant ABS is specified where the enclosure must meet UL94 V-0 or a comparable rail or appliance standard.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• plan the trim line on a flat face so the router can hold tolerance
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• as formed gloss
• matte finish
• satin finish
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• RoHS compliant grades available
• UL94 V-0 grades available
• PPAP or ISIR on request

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 10–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

Can you make it in another material?

Any grade in this family can be swapped in. Send the requirement and the material will be quoted with the price difference shown.

How fast is the first article?

Seven to fifteen working days from drawing release for sample tooling, with production tooling in three to four weeks.

Are spare parts available later?

Tooling is stored against the part number for the life of the programme, so replacements or spare panels can be released at any time.
