Thick Gauge PETG Seat Shells in 4 mm – Dental Equipment Range

These PETG seat shells are thick gauge vacuum formed parts supplied to drawing for dental equipment. They are formed from PETG sheet at 4 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
• PETG 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
• food contact declarations available

Typical applications

• chair shrouds
• cabinet panels
• suction unit housings
• instrument tray covers
• seat shells used across general dental equipment builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
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. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: PETG

PETG forms at a low temperature, holds detail well and is accepted for food contact, which suits trays, guards and machine covers in food plants.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• plan the trim line on a flat face so the router can hold tolerance
• 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

• clear protective film
• hot stamped accents
• as formed gloss
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

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

• REACH compliant sheet available
• PPAP or ISIR on request
• RoHS compliant grades available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 2–3 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
