1.5 mm polypropylene Protective Guards Manufacturer for Cleaning And Sanitation Equipment

These polypropylene protective guards are thick gauge vacuum formed parts supplied to drawing for cleaning and sanitation equipment. They are formed from polypropylene sheet at 1.5 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
• Pad printed logos 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
• REACH compliant sheet available

Typical applications

• tool trays
• scrubber tanks
• solution tank liners
• machine covers
• protective guards used across general cleaning and sanitation equipment builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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

Finishing and assembly options

• pad printed logos
• UV stabilised as formed
• soft touch coating
• 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
• dimension reports with every release

Packing and delivery

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

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.

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.
