ASA Battery Boxes Vacuum Formed in 5 mm for Elevator And Escalator Interiors

These ASA battery boxes are thick gauge vacuum formed parts supplied to drawing for elevator and escalator interiors. They are formed from ASA sheet at 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
• ASA 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
• REACH compliant sheet available

Typical applications

• landing sill covers
• car linings
• ceiling panels
• handrail deck covers
• battery boxes 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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: ASA

ASA keeps its colour and surface under UV better than ABS, which suits outdoor covers that are not painted.

Design notes

• use corner radii of at least three times the sheet thickness to avoid thinning
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• 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

Finishing and assembly options

• anti static coating
• clear protective film
• pad printed logos
• 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.

• RoHS compliant grades available
• dimension reports with every release
• PPAP or ISIR on request

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 3–4 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
