Skid Plates HDPE in 8 mm for Truck And Bus – Formed to Drawing

These HDPE skid plates are thick gauge vacuum formed parts supplied to drawing for truck and bus. They are formed from HDPE 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
• HDPE keeps the weight down while stiffness is held through the formed shape
• Uv stabilised as formed 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
• food contact declarations available

Typical applications

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

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

Material: HDPE

HDPE is chosen for chemical resistance and impact strength at low temperature. It needs more heat and a longer cooling cycle than ABS, and it is painted only after flame or plasma treatment.

Design notes

• 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
• 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

• UV stabilised as formed
• as formed gloss
• anti static 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• food contact declarations available
• dimension reports with every release
• PPAP or ISIR on request

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

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.

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.
