Hoppers ABS/PMMA in 3 mm for Battery Energy Storage – Formed to Drawing

These ABS/PMMA hoppers are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from ABS/PMMA 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
• ABS/PMMA keeps the weight down while stiffness is held through the formed shape
• Mould texture 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
• REACH compliant sheet available

Typical applications

• cell trays
• cabinet liners
• battery pack covers
• vent shrouds
• hoppers 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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. The part cools on a jig so the shape is held while the material stabilises.

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

• use corner radii of at least three times the sheet thickness to avoid thinning
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• mould texture
• two coat polyurethane paint
• anti static coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• food contact declarations available
• ISO 9001 quality system
• dimension reports with every release

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 2–3 weeks, 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.

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.
