3 mm PMMA acrylic Fenders Manufacturer for Solar And Wind Energy

These PMMA acrylic fenders are thick gauge vacuum formed parts supplied to drawing for solar and wind energy. They are formed from PMMA acrylic sheet at 3 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
• PMMA acrylic keeps the weight down while stiffness is held through the formed shape
• Emi shielding coating 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
• REACH compliant sheet available

Typical applications

• nacelle access panels
• inverter covers
• combiner box housings
• cable covers
• fenders used across general solar and wind energy 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. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

Material: PMMA acrylic

PMMA gives the glossiest surface and the best UV stability, which is why it is used for light housings and outdoor sign faces.

Design notes

• use corner radii of at least three times the sheet thickness to avoid thinning
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• EMI shielding coating
• UV stabilised as formed
• as formed gloss
• 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. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• dimension reports with every release
• RoHS compliant grades available
• UL94 V-0 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

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.

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.
