8 mm flame retardant ABS Fenders Manufacturer for Solar And Wind Energy

These flame retardant ABS fenders are thick gauge vacuum formed parts supplied to drawing for solar and wind energy. They are formed from flame retardant ABS sheet at 8 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
• UL94 V-0 grades available

Typical applications

• cable covers
• nacelle access panels
• combiner box housings
• inverter covers
• fenders used across general solar and wind energy builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. The part cools on a jig so the shape is held while the material stabilises.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

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

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• 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

• two coat polyurethane paint
• soft touch coating
• EMI shielding 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.

• dimension reports with every release
• PPAP or ISIR on request
• UL94 V-0 grades 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

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.

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.
