OEM Cart Panels PMMA acrylic in 8 mm for Defence And Security Equipment

These PMMA acrylic cart panels are thick gauge vacuum formed parts supplied to drawing for defence and security equipment. They are formed from PMMA acrylic 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
• PMMA acrylic keeps the weight down while stiffness is held through the formed shape
• Anti static 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
• RoHS compliant grades available

Typical applications

• transport trays
• antenna covers
• case shells
• console covers
• cart panels used across general defence and security equipment builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. The part cools on a jig so the shape is held while the material stabilises.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

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

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• use corner radii of at least three times the sheet thickness to avoid thinning
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• anti static coating
• silk screened markings
• anti graffiti 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• PPAP or ISIR on request
• UL94 V-0 grades available
• ISO 9001 quality system

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. 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

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.

Can you make it in another material?

Any grade in this family can be swapped in. Send the requirement and the material will be quoted with the price difference shown.

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.
