Thick Gauge Vacuum Forming of Equipment Covers in Commercial Laundry at 6 mm

Vacuum formed equipment covers are used across commercial laundry because they can be produced without the tooling spend of injection moulding and without the weight of sheet metal. This page covers how 6 mm Kydex acrylic PVC sheet is formed for commercial laundry, 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 equipment covers 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 equipment covers the sheet gauge is selected from the load case rather than from habit, and Kydex acrylic PVC is the material most often specified for this combination.

Typical specification

Where these parts are used

• drum covers for commercial laundry
• control bezels for commercial laundry
• machine front panels for commercial laundry
• detergent tray liners for commercial laundry
• equipment covers in general commercial laundry 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: Kydex acrylic PVC

Kydex acrylic PVC sheet is specified for interior trim that must resist scuffing and meet fire, smoke and toxicity rules.

Design tips for this part

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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
• 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

Quality and inspection

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.

Cost and lead time

Tooling is the main cost driver at low volume, so a 6 mm equipment covers for commercial laundry 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 lighter weight 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

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 quantities make sense?

Vacuum forming pays off from roughly 25 pieces up to several thousand a year. Below that, printed or composite tooling keeps the setup cost low.

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.

Getting started

Send the drawing or a photo of the current equipment covers 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.
