polypropylene Wheel Covers Vacuum Formed in 4 mm for Catering And Kitchen Equipment

These polypropylene wheel covers are thick gauge vacuum formed parts supplied to drawing for catering and kitchen equipment. They are formed from polypropylene 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
• polypropylene 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
• dimension reports with every release

Typical applications

• service trolley trays
• refrigerated well covers
• hood panels
• bain marie liners
• wheel covers used across general catering and kitchen equipment builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: polypropylene

Polypropylene survives repeated impact and most cleaning chemicals. Its low forming temperature keeps cycles short, but it shrinks more, so the mould is cut with the shrink factor built in.

Design notes

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

Finishing and assembly options

• matte finish
• anti graffiti coating
• as formed gloss
• 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.

• material certificates with every batch
• REACH compliant sheet available
• food contact declarations available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 3–4 weeks, 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.

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.

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.
