OEM Display Shells TPO in 6 mm for Hvac Equipment

These TPO display shells are thick gauge vacuum formed parts supplied to drawing for HVAC equipment. They are formed from TPO sheet at 6 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
• TPO keeps the weight down while stiffness is held through the formed shape
• Matte 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
• RoHS compliant grades available

Typical applications

• fan shrouds
• duct end caps
• unit covers
• condensate trays
• display shells used across general HVAC equipment 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. 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: TPO

TPO sheet is used where the part lives outdoors: it stays flexible in the cold and resists UV without a coating.

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• plan the trim line on a flat face so the router can hold tolerance
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• matte finish
• pad printed logos
• as formed gloss
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• ISO 9001 quality system
• REACH compliant sheet available
• dimension reports with every release

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

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.

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.
