polycarbonate Instrument Bezels Vacuum Formed in 10 mm for Construction Machinery

These polycarbonate instrument bezels are thick gauge vacuum formed parts supplied to drawing for construction machinery. They are formed from polycarbonate sheet at 10 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
• 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
• ISO 9001 quality system

Typical applications

• engine covers
• toolbox liners
• cab panels
• guard shells
• instrument bezels used across general construction machinery builds

How it is made

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

• 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
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• two coat polyurethane paint
• as formed gloss
• UV stabilised as formed
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• RoHS compliant grades available
• REACH compliant sheet available
• 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 10–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.

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.
