ASA Seat Shells Vacuum Formed in 5 mm for Ev Charging

These ASA seat shells are thick gauge vacuum formed parts supplied to drawing for EV charging. They are formed from ASA 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
• ASA keeps the weight down while stiffness is held through the formed shape
• Hot stamped accents 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
• RoHS compliant grades available

Typical applications

• charger housings
• cable management panels
• payment terminal bezels
• wallbox covers
• seat shells 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. 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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: ASA

ASA keeps its colour and surface under UV better than ABS, which suits outdoor covers that are not painted.

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• 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
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• hot stamped accents
• EMI shielding coating
• powder coat 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• RoHS compliant 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 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.

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.
