UV stabilised HDPE Ventilation Shrouds Vacuum Formed in 5 mm for Retail Display

These UV stabilised HDPE ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for retail display. They are formed from UV stabilised HDPE sheet at 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
• UV stabilised HDPE 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
• food contact declarations available

Typical applications

• display shells
• header panels
• shelf trays
• counter risers
• ventilation shrouds used across general retail display builds

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: UV stabilised HDPE

UV stabilised HDPE is the standard answer for outdoor tanks, agricultural hoppers and marine hardware that see direct sun.

Design notes

• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• 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

• as formed gloss
• matte finish
• soft touch 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. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• RoHS compliant grades available
• REACH compliant sheet 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 2–3 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
