Fenders 8 mm PETG Supplier for Battery Energy Storage Equipment

These PETG fenders are thick gauge vacuum formed parts supplied to drawing for battery energy storage. They are formed from PETG sheet at 8 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
• Silk screened markings 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
• dimension reports with every release

Typical applications

• cell trays
• battery pack covers
• 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 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. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• silk screened markings
• mould texture
• anti graffiti 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.

• REACH compliant sheet available
• UL94 V-0 grades 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 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.

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.
