Display Shells polycarbonate in 10 mm for Battery Energy Storage – Formed to Drawing

These polycarbonate display shells are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from polycarbonate sheet at 10 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
• Powder coat finish 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
• display shells used across general battery energy storage builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
2. The part cools on a jig so the shape is held while the material stabilises.
3. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

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

• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• 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

Finishing and assembly options

• powder coat finish
• soft touch coating
• anti graffiti coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• dimension reports with every release
• RoHS compliant grades available
• PPAP or ISIR on request

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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

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.

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.
