OEM Ventilation Shrouds food grade polypropylene in 5 mm for Fitness Equipment

These food grade polypropylene ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for fitness equipment. They are formed from food grade polypropylene sheet at 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
• food grade polypropylene keeps the weight down while stiffness is held through the formed shape
• Emi shielding coating 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
• UL94 V-0 grades available

Typical applications

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

How it is made

1. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. The part cools on a jig so the shape is held while the material stabilises.

Material: food grade polypropylene

Food grade polypropylene is used for trays, hoppers and liners that touch product, and it can be washed with caustic cleaners.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• plan the trim line on a flat face so the router can hold tolerance
• use corner radii of at least three times the sheet thickness to avoid thinning

Finishing and assembly options

• EMI shielding coating
• as formed gloss
• mould texture
• 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. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• RoHS compliant grades available
• material certificates with every batch
• dimension reports with every release

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. 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

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.
