UV stabilised HDPE Sign Faces Vacuum Formed in 5 mm for Semiconductor Equipment

These UV stabilised HDPE sign faces are thick gauge vacuum formed parts supplied to drawing for semiconductor equipment. 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
• 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
• PPAP or ISIR on request

Typical applications

• equipment covers
• fan shrouds
• carrier trays
• chemical tank liners
• sign faces used across general semiconductor equipment builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

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

• 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
• soft touch coating
• clear protective film
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• UL94 V-0 grades available
• dimension reports with every release
• ISO 9001 quality system

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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

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.

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.
