ABS Light Housings Vacuum Formed in 4 mm for Truck And Bus

These ABS light housings are thick gauge vacuum formed parts supplied to drawing for truck and bus. They are formed from ABS sheet at 4 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 keeps the weight down while stiffness is held through the formed shape
• Anti graffiti coating 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
• RoHS compliant grades available

Typical applications

• stepwell panels
• engine tunnel covers
• bunk liners
• interior trim panels
• light housings used across general truck and bus builds

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
3. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

Material: ABS

ABS is the default choice where the part needs stiffness, a paint finish and clean trimmed edges. It forms evenly, takes texture well and bonds with standard solvents.

Design notes

• use corner radii of at least three times the sheet thickness to avoid thinning
• 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
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• anti graffiti coating
• clear protective film
• silk screened markings
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• REACH compliant sheet available
• UL94 V-0 grades available
• RoHS compliant grades available

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. 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.
