1.5 mm LDPE Fenders Manufacturer for Truck And Bus

These LDPE fenders are thick gauge vacuum formed parts supplied to drawing for truck and bus. 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
• As formed gloss 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

• stepwell panels
• interior trim panels
• bunk liners
• engine tunnel covers
• fenders used across general truck and bus builds

How it is made

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

Material: LDPE

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

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

• as formed gloss
• mould texture
• silk screened markings
• 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. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• dimension reports with every release
• food contact declarations available
• RoHS compliant 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.
