Thick Gauge ABS/PMMA Plastic Enclosures in 2 mm – Battery Energy Storage Range

These ABS/PMMA plastic enclosures are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from ABS/PMMA sheet at 2 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
• ABS/PMMA 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
• UL94 V-0 grades available

Typical applications

• vent shrouds
• battery pack covers
• cabinet liners
• cell trays
• plastic enclosures 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. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

Material: ABS/PMMA

ABS/PMMA combines an ABS core with a hard acrylic cap, so the part has the toughness of ABS and the UV and scratch resistance of acrylic.

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• anti static coating
• hot stamped accents
• 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

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.

• UL94 V-0 grades available
• PPAP or ISIR on request
• dimension reports with every release

Packing and delivery

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

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.

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.
