Thick Gauge polypropylene Access Panels in 6 mm – Garden And Outdoor Power Equipment Range

These polypropylene access panels are thick gauge vacuum formed parts supplied to drawing for garden and outdoor power equipment. They are formed from polypropylene sheet at 6 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
• PPAP or ISIR on request

Typical applications

• mower decks
• tool trays
• grass catcher shells
• engine covers
• access panels used across general garden and outdoor power equipment builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
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

• 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
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• as formed gloss
• two coat polyurethane paint
• satin 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• REACH compliant sheet available
• material certificates with every batch
• RoHS compliant grades available

Packing and delivery

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

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.

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.
