LDPE Equipment Covers Vacuum Formed in 4 mm for Rail Transit Interiors

These LDPE equipment covers are thick gauge vacuum formed parts supplied to drawing for rail transit interiors. They are formed from LDPE 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
• LDPE keeps the weight down while stiffness is held through the formed shape
• Powder coat finish 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

• luggage rack trays
• ceiling end caps
• seat shells
• wall panels
• equipment covers used across general rail transit interiors builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: LDPE

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

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• 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
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• powder coat finish
• silk screened markings
• anti graffiti coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• food contact declarations available
• dimension reports with every release
• material certificates with every batch

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

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.

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.
