10 mm recycled HDPE Hoppers Manufacturer for Agricultural Machinery

These recycled HDPE hoppers are thick gauge vacuum formed parts supplied to drawing for agricultural machinery. They are formed from recycled HDPE sheet at 10 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
• recycled HDPE 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
• ISO 9001 quality system

Typical applications

• tractor hood panels
• cab interior trim
• hopper liners
• fertiliser tank covers
• hoppers used across general agricultural machinery builds

How it is made

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

Material: recycled HDPE

Recycled HDPE sheet lowers material cost and supports sustainability targets, with mechanical properties close to virgin sheet for non critical parts.

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• plan the trim line on a flat face so the router can hold tolerance
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• silk screened markings
• as formed gloss
• powder coat finish
• 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. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• PPAP or ISIR on request
• material certificates with every batch
• dimension reports with every release

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. Standard lead time to first article is 10–15 working days, 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.

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.
