ASA Tank Covers Vacuum Formed in 5 mm for Pool And Spa

These ASA tank covers are thick gauge vacuum formed parts supplied to drawing for pool and spa. They are formed from 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
• ASA keeps the weight down while stiffness is held through the formed shape
• Satin 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

• chemical feeder guards
• filter housings
• pump covers
• spa side panels
• tank covers used across general pool and spa builds

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

Material: ASA

ASA keeps its colour and surface under UV better than ABS, which suits outdoor covers that are not painted.

Design notes

• 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
• plan the trim line on a flat face so the router can hold tolerance
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• satin finish
• two coat polyurethane paint
• pad printed logos
• 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• material certificates with every batch
• REACH compliant sheet available
• ISO 9001 quality system

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 3–4 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.

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.
