12 mm HDPE Access Panels Manufacturer for Aerospace Interiors

These HDPE access panels are thick gauge vacuum formed parts supplied to drawing for aerospace interiors. They are formed from HDPE sheet at 12 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
• HDPE keeps the weight down while stiffness is held through the formed shape
• Silk screened markings 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
• dimension reports with every release

Typical applications

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

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: HDPE

HDPE is chosen for chemical resistance and impact strength at low temperature. It needs more heat and a longer cooling cycle than ABS, and it is painted only after flame or plasma treatment.

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• plan the trim line on a flat face so the router can hold tolerance
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• silk screened markings
• two coat polyurethane paint
• hot stamped accents
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• REACH compliant sheet available
• food contact declarations available
• material certificates with every batch

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 7–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

What quantity can I order?

Sample quantities start at one piece off printed tooling. The process pays back from about 25 pieces a year and runs well into several thousand.

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.
