Thick Gauge PMMA acrylic Ventilation Shrouds in 2 mm – Material Handling Range

These PMMA acrylic ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for material handling. They are formed from PMMA acrylic sheet at 2 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
• 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
• dimension reports with every release

Typical applications

• pallet tops
• tote liners
• picker truck panels
• conveyor covers
• ventilation shrouds used across general material handling builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. The part cools on a jig so the shape is held while the material stabilises.

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

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• two coat polyurethane paint
• hot stamped accents
• silk screened markings
• 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. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• RoHS compliant grades available
• PPAP or ISIR on request
• 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 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.

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.
