Wheel Covers polypropylene in 10 mm for Fitness Equipment – Formed to Drawing

These polypropylene wheel covers are thick gauge vacuum formed parts supplied to drawing for fitness equipment. They are formed from polypropylene sheet at 10 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
• As formed gloss 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

• weight stack shrouds
• seat shells
• console housings
• treadmill motor covers
• wheel covers used across general fitness equipment builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
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. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

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

• use corner radii of at least three times the sheet thickness to avoid thinning
• 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
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• as formed gloss
• satin finish
• powder coat finish
• 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.

• UL94 V-0 grades available
• RoHS compliant grades available
• material certificates with every batch

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. Standard lead time to first article is 7–15 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.

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.
