flame retardant ABS Ventilation Shrouds Vacuum Formed in 8 mm for Cleaning And Sanitation Equipment

These flame retardant ABS ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for cleaning and sanitation equipment. They are formed from flame retardant ABS sheet at 8 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
• flame retardant ABS keeps the weight down while stiffness is held through the formed shape
• Two coat polyurethane paint 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

• solution tank liners
• tool trays
• scrubber tanks
• machine covers
• ventilation shrouds used across general cleaning and sanitation equipment builds

How it is made

1. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
2. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: flame retardant ABS

Flame retardant ABS is specified where the enclosure must meet UL94 V-0 or a comparable rail or appliance standard.

Design notes

• use corner radii of at least three times the sheet thickness to avoid thinning
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• two coat polyurethane paint
• 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

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.

• food contact declarations available
• ISO 9001 quality system
• 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 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.

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.

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.
