food grade polypropylene Fenders Vacuum Formed in 5 mm for Dental Equipment

These food grade polypropylene fenders are thick gauge vacuum formed parts supplied to drawing for dental equipment. They are formed from food grade polypropylene 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
• food grade polypropylene keeps the weight down while stiffness is held through the formed shape
• Two coat polyurethane paint 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
• dimension reports with every release

Typical applications

• instrument tray covers
• suction unit housings
• cabinet panels
• chair shrouds
• fenders used across general dental equipment 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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
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

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

Finishing and assembly options

• two coat polyurethane paint
• satin finish
• 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• REACH compliant sheet available
• PPAP or ISIR on request
• material certificates with every batch

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. 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

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.

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.
