Seat Shells PVC in 1.5 mm for Elevator And Escalator Interiors – Formed to Drawing

These PVC seat shells are thick gauge vacuum formed parts supplied to drawing for elevator and escalator interiors. They are formed from PVC sheet at 1.5 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
• PVC keeps the weight down while stiffness is held through the formed shape
• Satin finish 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
• REACH compliant sheet available

Typical applications

• ceiling panels
• handrail deck covers
• landing sill covers
• car linings
• seat shells used across general elevator and escalator interiors builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
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.

Material: PVC

PVC sheet brings flame retardancy and chemical resistance at a low price, common in equipment covers and clean room panels.

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• use corner radii of at least three times the sheet thickness to avoid thinning
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• satin finish
• hot stamped accents
• EMI shielding coating
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• dimension reports with every release
• food contact declarations available
• PPAP or ISIR on request

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 10–15 working days, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
