Thick Gauge ESD safe ABS Ventilation Shrouds in 2 mm – Hvac Equipment Range

These ESD safe ABS ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for HVAC equipment. They are formed from ESD safe ABS sheet at 2 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
• 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
• material certificates with every batch

Typical applications

• condensate trays
• unit covers
• fan shrouds
• duct end caps
• ventilation shrouds used across general HVAC equipment 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. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

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
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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

• EMI shielding coating
• matte finish
• pad printed logos
• 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.

• UL94 V-0 grades available
• RoHS compliant grades available
• food contact declarations 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.

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.
