Cart Panels ASA in 1.5 mm for Semiconductor Equipment – Formed to Drawing

These ASA cart panels are thick gauge vacuum formed parts supplied to drawing for semiconductor equipment. They are formed from ASA sheet at 1.5 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
• Silk screened markings 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
• UL94 V-0 grades available

Typical applications

• chemical tank liners
• equipment covers
• fan shrouds
• carrier trays
• cart panels used across general semiconductor equipment builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. The part cools on a jig so the shape is held while the material stabilises.

Material: ASA

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

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

Finishing and assembly options

• silk screened markings
• clear protective film
• anti static coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• ISO 9001 quality system
• UL94 V-0 grades available
• REACH compliant sheet available

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 10–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
