OEM Hoppers food grade polypropylene in 8 mm for Ev Charging

These food grade polypropylene hoppers are thick gauge vacuum formed parts supplied to drawing for EV charging. They are formed from food grade polypropylene sheet at 8 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
• Silk screened markings 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
• RoHS compliant grades available

Typical applications

• charger housings
• wallbox covers
• payment terminal bezels
• cable management panels
• hoppers used across general EV charging builds

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

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
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• 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

Finishing and assembly options

• silk screened markings
• matte finish
• powder coat finish
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• RoHS compliant grades available
• 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 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.

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.

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.
