8 mm UV stabilised HDPE Tank Covers Manufacturer for Semiconductor Equipment

These UV stabilised HDPE tank covers are thick gauge vacuum formed parts supplied to drawing for semiconductor equipment. They are formed from UV stabilised 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
• UV stabilised HDPE keeps the weight down while stiffness is held through the formed shape
• Two coat polyurethane paint 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
• material certificates with every batch

Typical applications

• carrier trays
• fan shrouds
• chemical tank liners
• equipment covers
• tank covers used across general semiconductor equipment 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. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

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

• plan the trim line on a flat face so the router can hold tolerance
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• 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

• two coat polyurethane paint
• anti static coating
• satin finish
• 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. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• material certificates with every batch
• PPAP or ISIR on request
• REACH compliant sheet 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

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.

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.
