Battery Boxes PC/ASA in 3 mm for Truck And Bus – Formed to Drawing

These PC/ASA battery boxes are thick gauge vacuum formed parts supplied to drawing for truck and bus. They are formed from PC/ASA sheet at 3 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
• PC/ASA 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
• REACH compliant sheet available

Typical applications

• engine tunnel covers
• stepwell panels
• interior trim panels
• bunk liners
• battery boxes 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. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: PC/ASA

PC/ASA blends impact strength with weatherability, used for outdoor equipment covers that also need to survive knocks.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• as formed gloss
• soft touch coating
• two coat polyurethane paint
• 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.

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

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

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.

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.
