food grade polypropylene Storage Bins Vacuum Formed in 2 mm for Telecom And Network Cabinets

These food grade polypropylene storage bins are thick gauge vacuum formed parts supplied to drawing for telecom and network cabinets. They are formed from food grade polypropylene sheet at 2 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
• food grade polypropylene keeps the weight down while stiffness is held through the formed shape
• Emi shielding 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
• PPAP or ISIR on request

Typical applications

• cable trays
• cabinet tops
• antenna radomes
• equipment shelves
• storage bins used across general telecom and network cabinets builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.

Material: food grade polypropylene

Food grade polypropylene is used for trays, hoppers and liners that touch product, and it can be washed with caustic cleaners.

Design notes

• 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
• 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

Finishing and assembly options

• EMI shielding coating
• anti static coating
• mould texture
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• ISO 9001 quality system
• dimension reports with every release
• food contact declarations available

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. Standard lead time to first article is 7–15 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.
