Fenders flame retardant ABS in 5 mm for Semiconductor Equipment – Formed to Drawing

These flame retardant ABS fenders are thick gauge vacuum formed parts supplied to drawing for semiconductor equipment. They are formed from flame retardant ABS 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
• 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
• PPAP or ISIR on request

Typical applications

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

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

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

Finishing and assembly options

• two coat polyurethane paint
• satin finish
• clear protective film
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• REACH compliant sheet available
• material certificates with every batch
• RoHS compliant grades available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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

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.

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.
