Thick Gauge LDPE Battery Boxes in 1.5 mm – Marine And Boat Building Range

These LDPE battery boxes are thick gauge vacuum formed parts supplied to drawing for marine and boat building. They are formed from LDPE sheet at 1.5 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
• LDPE 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

• console shells
• hatch covers
• battery box liners
• seat bases
• battery boxes used across general marine and boat building builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

Material: LDPE

LDPE is flexible and tough in thin section, used for liners and protective covers that have to bend during fitting.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• 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
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

• silk screened markings
• matte finish
• mould texture
• 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.

• material certificates with every batch
• REACH compliant sheet available
• ISO 9001 quality system

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 3–4 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
