OEM Fenders recycled HDPE in 6 mm for Battery Energy Storage

These recycled HDPE fenders are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from recycled HDPE 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
• recycled HDPE keeps the weight down while stiffness is held through the formed shape
• Two coat polyurethane paint 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
• material certificates with every batch

Typical applications

• battery pack covers
• cell trays
• vent shrouds
• cabinet liners
• fenders 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. The part cools on a jig so the shape is held while the material stabilises.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: recycled HDPE

Recycled HDPE sheet lowers material cost and supports sustainability targets, with mechanical properties close to virgin sheet for non critical parts.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• use corner radii of at least three times the sheet thickness to avoid thinning
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• two coat polyurethane paint
• silk screened markings
• 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

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.

• ISO 9001 quality system
• material certificates with every batch
• UL94 V-0 grades available

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. 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

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.

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.
