Battery Boxes TPO in 8 mm for Motorcycle And Scooter – Formed to Drawing

These TPO battery boxes are thick gauge vacuum formed parts supplied to drawing for motorcycle and scooter. They are formed from TPO sheet at 8 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
• TPO keeps the weight down while stiffness is held through the formed shape
• Soft touch 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

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

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. The part cools on a jig so the shape is held while the material stabilises.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: TPO

TPO sheet is used where the part lives outdoors: it stays flexible in the cold and resists UV without a coating.

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• 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

Finishing and assembly options

• soft touch coating
• mould texture
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• RoHS compliant grades available
• dimension reports with every release
• REACH compliant sheet available

Packing and delivery

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

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.

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.
