Battery Boxes HDPE in 3 mm for Motorcycle And Scooter – Formed to Drawing

These HDPE battery boxes are thick gauge vacuum formed parts supplied to drawing for motorcycle and scooter. They are formed from HDPE 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
• HDPE 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

• windscreen mounts
• side covers
• top box shells
• fairing panels
• battery boxes used across general motorcycle and scooter builds

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

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
• use corner radii of at least three times the sheet thickness to avoid thinning
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• as formed gloss
• powder coat finish
• 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.

• ISO 9001 quality system
• dimension reports with every release
• 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

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.
