HDPE Skid Plates Vacuum Formed in 6 mm for Marine And Boat Building

These HDPE skid plates are thick gauge vacuum formed parts supplied to drawing for marine and boat building. They are formed from HDPE sheet at 6 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
• Anti static coating 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
• ISO 9001 quality system

Typical applications

• battery box liners
• seat bases
• hatch covers
• console shells
• skid plates 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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. The part cools on a jig so the shape is held while the material stabilises.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

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

• plan the trim line on a flat face so the router can hold tolerance
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• 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

• anti static coating
• matte finish
• anti graffiti coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• REACH compliant sheet available
• UL94 V-0 grades available
• ISO 9001 quality system

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. 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

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.

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.
