Tank Liners ABS in 4 mm for Laboratory Instruments – Formed to Drawing

These ABS tank liners are thick gauge vacuum formed parts supplied to drawing for laboratory instruments. They are formed from ABS 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
• ABS keeps the weight down while stiffness is held through the formed shape
• Silk screened markings 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

• instrument covers
• fume hood liners
• analyser housings
• sample tray systems
• tank liners used across general laboratory instruments builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. The part cools on a jig so the shape is held while the material stabilises.
5. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

Material: ABS

ABS is the default choice where the part needs stiffness, a paint finish and clean trimmed edges. It forms evenly, takes texture well and bonds with standard solvents.

Design notes

• 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
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• silk screened markings
• EMI shielding coating
• powder coat finish
• 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• material certificates with every batch
• food contact declarations available
• RoHS compliant grades available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 7–15 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.

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.
