HDPE Plastic Enclosures Vacuum Formed in 5 mm for Ev Charging

These HDPE plastic enclosures are thick gauge vacuum formed parts supplied to drawing for EV charging. They are formed from 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
• HDPE keeps the weight down while stiffness is held through the formed shape
• Clear protective film 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

• charger housings
• payment terminal bezels
• cable management panels
• wallbox covers
• plastic enclosures used across general EV charging builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• 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
• 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

Finishing and assembly options

• clear protective film
• anti graffiti coating
• soft touch coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• REACH compliant sheet available
• PPAP or ISIR on request
• food contact declarations available

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

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.
