OEM Seat Shells ESD safe ABS in 4 mm for Food Processing

These ESD safe ABS seat shells are thick gauge vacuum formed parts supplied to drawing for food processing. They are formed from ESD safe 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
• ESD safe ABS keeps the weight down while stiffness is held through the formed shape
• Clear protective film 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
• washdown panels
• conveyor guards
• product trays
• seat shells used across general food processing builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
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: ESD safe ABS

ESD safe ABS keeps surface resistivity in the dissipative range, used for electronics carriers, tray systems and equipment covers in assembly areas.

Design notes

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• 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
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• clear protective film
• anti graffiti coating
• UV stabilised as formed
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• PPAP or ISIR on request
• REACH compliant sheet available
• ISO 9001 quality system

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

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.

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.
