Cowls 12 mm ABS/PC Supplier for Rail Transit Interiors Equipment

These ABS/PC cowls are thick gauge vacuum formed parts supplied to drawing for rail transit interiors. They are formed from ABS/PC 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
• ABS/PC keeps the weight down while stiffness is held through the formed shape
• Hot stamped accents 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
• PPAP or ISIR on request

Typical applications

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

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
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: ABS/PC

ABS/PC carries higher heat resistance than ABS alone, which matters for housings around motors, drives and power electronics.

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• use corner radii of at least three times the sheet thickness to avoid thinning
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• hot stamped accents
• soft touch coating
• EMI shielding coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

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

• RoHS compliant grades available
• ISO 9001 quality system
• material certificates with every batch

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 3–4 weeks, 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.

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.

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.
