OEM Component Trays food grade polypropylene in 1.5 mm for Telecom And Network Cabinets

These food grade polypropylene component trays are thick gauge vacuum formed parts supplied to drawing for telecom and network cabinets. They are formed from food grade polypropylene 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
• food grade polypropylene keeps the weight down while stiffness is held through the formed shape
• Pad printed logos 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

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

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

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

• 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
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly

Finishing and assembly options

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

• material certificates with every batch
• RoHS compliant grades available
• 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 2–3 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

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.

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.
