2 mm ABS Door Panels Vacuum Forming for Office Furniture

Vacuum formed door panels are used across office furniture because they can be produced without the tooling spend of injection moulding and without the weight of sheet metal. This page covers how 2 mm ABS sheet is formed for office furniture, what tolerances are realistic, and what has to be on the drawing before tooling starts.

The route below is the one used for most of the door panels shipped from this plant: sheet is heated on the forming machine, drawn over an aluminium or composite mould, cooled on a jig, then trimmed on a 5-axis router. For door panels the sheet gauge is selected from the load case rather than from habit, and ABS is the material most often specified for this combination.

Typical specification

Where these parts are used

• chair shells for office furniture
• screen frames for office furniture
• cable trays for office furniture
• desk modesty panels for office furniture
• door panels in general office furniture builds

How the part is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. The part cools on a jig so the shape is held while the material stabilises.
6. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
7. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

Material notes: ABS

ABS is the default choice where the part needs stiffness, a paint finish and clean trimmed edges. It forms evenly, takes texture well and bonds with standard solvents.

Design tips for this part

• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• 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
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Quality and inspection

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.

Cost and lead time

Tooling is the main cost driver at low volume, so a 2 mm door panels for office furniture is usually quoted with a composite or printed mould first and the aluminium tool cut once the design is frozen. That keeps the first article cost low and gives a real part to test before the production tool exists. The result is shorter lead time compared with the alternatives, and a piece price that stays stable across repeat releases.

• Sample tooling: 7–15 working days
• Production tooling: 3–4 weeks
• Repeat orders run on stored tooling with no new proving run

Frequently asked questions

Do you supply certificates?

Material certificates, dimensional reports and flame retardancy or food contact declarations are issued with the shipment where the specification requires them.

How long does tooling take?

Sample and first article tooling is usually cut in 7 to 15 working days. Production aluminium tools take 3 to 4 weeks depending on size and cooling layout.

What do you need to quote?

A 3D file or drawing, the material if it is fixed, the annual quantity and the finish. Photos of the current part are enough for a first estimate.

Getting started

Send the drawing or a photo of the current door panels with the quantity and the finish. The first reply is a manufacturability review with the wall thickness, material and a quotation, so the decision is made on facts rather than on a price alone.
