TPO Storage Bins Vacuum Formed in 12 mm for Cleaning And Sanitation Equipment

These TPO storage bins are thick gauge vacuum formed parts supplied to drawing for cleaning and sanitation equipment. They are formed from TPO sheet at 12 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
• TPO keeps the weight down while stiffness is held through the formed shape
• Uv stabilised as formed 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
• food contact declarations available

Typical applications

• machine covers
• solution tank liners
• tool trays
• scrubber tanks
• storage bins 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. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

Material: TPO

TPO sheet is used where the part lives outdoors: it stays flexible in the cold and resists UV without a coating.

Design notes

• 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
• 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

• UV stabilised as formed
• EMI shielding coating
• two coat polyurethane paint
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• food contact declarations available
• REACH compliant sheet available
• 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 2–3 weeks, 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.
