PC/ASA Ventilation Shrouds Vacuum Formed in 5 mm for Water Treatment

These PC/ASA ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for water treatment. They are formed from PC/ASA sheet at 5 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
• PC/ASA keeps the weight down while stiffness is held through the formed shape
• Matte finish 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

• dosing tank liners
• filter housings
• channel covers
• control panel shells
• ventilation shrouds used across general water treatment builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

Material: PC/ASA

PC/ASA blends impact strength with weatherability, used for outdoor equipment covers that also need to survive knocks.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• plan the trim line on a flat face so the router can hold tolerance
• use corner radii of at least three times the sheet thickness to avoid thinning
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• matte finish
• anti static coating
• two coat polyurethane paint
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• REACH compliant sheet available
• UL94 V-0 grades available
• RoHS compliant grades available

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

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.

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.
