polycarbonate Dashboards Vacuum Formed in 3 mm for Rail Transit Interiors

These polycarbonate dashboards are thick gauge vacuum formed parts supplied to drawing for rail transit interiors. They are formed from polycarbonate sheet at 3 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
• Emi shielding 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
• REACH compliant sheet available

Typical applications

• luggage rack trays
• seat shells
• ceiling end caps
• wall panels
• dashboards used across general rail transit interiors 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. The part cools on a jig so the shape is held while the material stabilises.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

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
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• plan the trim line on a flat face so the router can hold tolerance
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• EMI shielding coating
• 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

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

• RoHS compliant grades available
• REACH compliant sheet available
• 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 10–15 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.

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.
