Sign Faces polycarbonate in 6 mm for Battery Energy Storage – Formed to Drawing

These polycarbonate sign faces are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from polycarbonate sheet at 6 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
• polycarbonate keeps the weight down while stiffness is held through the formed shape
• Anti static 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
• food contact declarations available

Typical applications

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

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: polycarbonate

Polycarbonate is used when the housing must survive impact or carry a glazing function. It must be dried before forming or the sheet will bubble.

Design notes

• 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
• plan the trim line on a flat face so the router can hold tolerance
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

• anti static coating
• mould texture
• UV stabilised as formed
• 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. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• material certificates with every batch
• food contact declarations available
• UL94 V-0 grades available

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

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.

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.
