3 mm TPO Instrument Bezels Manufacturer for Battery Energy Storage

These TPO instrument bezels are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from TPO 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
• TPO keeps the weight down while stiffness is held through the formed shape
• Silk screened markings 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
• ISO 9001 quality system

Typical applications

• battery pack covers
• vent shrouds
• cell trays
• cabinet liners
• instrument bezels used across general battery energy storage builds

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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

• silk screened markings
• 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

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• dimension reports with every release
• food contact declarations available
• UL94 V-0 grades available

Packing and delivery

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

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.
