Hoppers 4 mm PETG Supplier for Battery Energy Storage Equipment

These PETG hoppers are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from PETG sheet at 4 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
• PETG 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
• RoHS compliant grades available

Typical applications

• battery pack covers
• cell trays
• cabinet liners
• vent shrouds
• hoppers 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. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: PETG

PETG forms at a low temperature, holds detail well and is accepted for food contact, which suits trays, guards and machine covers in food plants.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• plan the trim line on a flat face so the router can hold tolerance
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• mould texture
• satin finish
• 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• PPAP or ISIR on request
• REACH compliant sheet available
• RoHS compliant grades available

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 10–15 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.

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.

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.
