5 mm polypropylene Ventilation Shrouds Manufacturer for Fitness Equipment

These polypropylene ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for fitness equipment. They are formed from 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
• 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

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

How it is made

1. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• use corner radii of at least three times the sheet thickness to avoid thinning
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• matte finish
• anti static coating
• 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

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• material certificates with every batch
• dimension reports with every release
• REACH compliant sheet available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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.

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.
