5 mm polypropylene Plastic Enclosures Manufacturer for Garden And Outdoor Power Equipment

These polypropylene plastic enclosures are thick gauge vacuum formed parts supplied to drawing for garden and outdoor power 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
• Powder coat 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
• RoHS compliant grades available

Typical applications

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

How it is made

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

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

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

• powder coat finish
• soft touch coating
• silk screened markings
• 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.

• food contact declarations available
• dimension reports with every release
• material certificates with every batch

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. 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

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.

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.
