Thick Gauge TPO Tank Liners in 3 mm – Food Processing Range

These TPO tank liners are thick gauge vacuum formed parts supplied to drawing for food processing. They are formed from TPO sheet at 3 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
• Emi shielding coating 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

• mixer covers
• product trays
• conveyor guards
• washdown panels
• tank liners used across general food processing builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
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: TPO

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

Design notes

• plan the trim line on a flat face so the router can hold tolerance
• 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
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• EMI shielding coating
• pad printed logos
• clear protective film
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• REACH compliant sheet available
• UL94 V-0 grades available
• dimension reports with every release

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 3–4 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.
