Battery Boxes 12 mm TPO Supplier for Agricultural Machinery Equipment

These TPO battery boxes are thick gauge vacuum formed parts supplied to drawing for agricultural machinery. They are formed from TPO 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
• TPO keeps the weight down while stiffness is held through the formed shape
• Clear protective film 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
• UL94 V-0 grades available

Typical applications

• cab interior trim
• tractor hood panels
• fertiliser tank covers
• hopper liners
• battery boxes used across general agricultural machinery builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• plan the trim line on a flat face so the router can hold tolerance
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• clear protective film
• pad printed logos
• hot stamped accents
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• RoHS compliant grades available
• UL94 V-0 grades available
• ISO 9001 quality system

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 7–15 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.

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.
