Seat Shells UV stabilised HDPE in 12 mm for Telecom And Network Cabinets – Formed to Drawing

These UV stabilised HDPE seat shells are thick gauge vacuum formed parts supplied to drawing for telecom and network cabinets. They are formed from UV stabilised HDPE sheet at 12 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

• cabinet tops
• equipment shelves
• cable trays
• antenna radomes
• seat shells used across general telecom and network cabinets builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. The part cools on a jig so the shape is held while the material stabilises.
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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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

Finishing and assembly options

• two coat polyurethane paint
• soft touch coating
• silk screened markings
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• REACH compliant sheet available
• UL94 V-0 grades available
• dimension reports with every release

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. 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.

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.

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.
