PETG Ventilation Shrouds Vacuum Formed in 2 mm for Refrigeration

These PETG ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for refrigeration. They are formed from PETG sheet at 2 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
• Uv stabilised as formed 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

• door panels
• condensate trays
• shelf trays
• inner liners
• ventilation shrouds 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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. The part cools on a jig so the shape is held while the material stabilises.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

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

• 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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• UV stabilised as formed
• matte finish
• mould texture
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• food contact declarations available
• material certificates with every batch
• UL94 V-0 grades available

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.

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.

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.
