12 mm PETG Cowls Manufacturer for Refrigeration

These PETG cowls are thick gauge vacuum formed parts supplied to drawing for refrigeration. They are formed from PETG sheet at 12 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
• Powder coat finish 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
• material certificates with every batch

Typical applications

• door panels
• inner liners
• shelf trays
• condensate trays
• cowls used across general refrigeration builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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
• 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

Finishing and assembly options

• powder coat finish
• hot stamped accents
• clear protective film
• 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.

• food contact declarations available
• REACH compliant sheet available
• PPAP or ISIR on request

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. 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.
