Thick Gauge LDPE Tank Liners in 4 mm – Dental Equipment Range

These LDPE tank liners are thick gauge vacuum formed parts supplied to drawing for dental equipment. They are formed from LDPE sheet at 4 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
• LDPE 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

• suction unit housings
• chair shrouds
• instrument tray covers
• cabinet panels
• tank liners used across general dental equipment builds

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
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. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

Material: LDPE

LDPE is flexible and tough in thin section, used for liners and protective covers that have to bend during fitting.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• 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
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• as formed gloss
• anti graffiti coating
• EMI shielding coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• ISO 9001 quality system
• food contact declarations available
• UL94 V-0 grades available

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

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.

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.

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.
