Seat Shells polycarbonate in 5 mm for Ev Charging – Formed to Drawing

These polycarbonate seat shells are thick gauge vacuum formed parts supplied to drawing for EV charging. They are formed from polycarbonate 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
• polycarbonate keeps the weight down while stiffness is held through the formed shape
• Soft touch coating 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
• UL94 V-0 grades available

Typical applications

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

How it is made

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

Material: polycarbonate

Polycarbonate is used when the housing must survive impact or carry a glazing function. It must be dried before forming or the sheet will bubble.

Design notes

• 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
• 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

Finishing and assembly options

• soft touch coating
• hot stamped accents
• 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.

• ISO 9001 quality system
• REACH compliant sheet available
• dimension reports with every release

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 10–15 working days, 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.

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.
