Thick Gauge flame retardant ABS Door Panels in 5 mm – Rail Transit Interiors Range

These flame retardant ABS door panels are thick gauge vacuum formed parts supplied to drawing for rail transit interiors. They are formed from flame retardant ABS sheet at 5 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
• Clear protective film 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
• material certificates with every batch

Typical applications

• ceiling end caps
• seat shells
• wall panels
• luggage rack trays
• door panels used across general rail transit interiors builds

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. The part cools on a jig so the shape is held while the material stabilises.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

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

• 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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• clear protective film
• silk screened markings
• anti graffiti coating
• 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.

• dimension reports with every release
• material certificates with every batch
• RoHS compliant grades available

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. 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.

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.
