OEM Wheel Covers polycarbonate in 1.5 mm for Hvac Equipment

These polycarbonate wheel covers are thick gauge vacuum formed parts supplied to drawing for HVAC equipment. They are formed from polycarbonate sheet at 1.5 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
• Silk screened markings 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
• REACH compliant sheet available

Typical applications

• unit covers
• fan shrouds
• condensate trays
• duct end caps
• wheel covers 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. 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: 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

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• silk screened markings
• pad printed logos
• 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

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• dimension reports with every release
• UL94 V-0 grades 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

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.

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.
