Ventilation Shrouds Kydex acrylic PVC in 4 mm for Elevator And Escalator Interiors – Formed to Drawing

These Kydex acrylic PVC ventilation shrouds are thick gauge vacuum formed parts supplied to drawing for elevator and escalator interiors. They are formed from Kydex acrylic PVC sheet at 4 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
• Kydex acrylic PVC keeps the weight down while stiffness is held through the formed shape
• Uv stabilised as formed 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
• material certificates with every batch

Typical applications

• ceiling panels
• car linings
• handrail deck covers
• landing sill covers
• ventilation shrouds used across general elevator and escalator interiors 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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

Material: Kydex acrylic PVC

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

Design notes

• 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
• plan the trim line on a flat face so the router can hold tolerance
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

• UV stabilised as formed
• matte finish
• two coat polyurethane paint
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• UL94 V-0 grades available
• food contact declarations available
• dimension reports with every release

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.

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.

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.
