OEM Seat Shells HIPS in 5 mm for Agricultural Machinery

These HIPS seat shells are thick gauge vacuum formed parts supplied to drawing for agricultural machinery. They are formed from HIPS 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
• HIPS keeps the weight down while stiffness is held through the formed shape
• Mould texture 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

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

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
3. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: HIPS

HIPS is the low cost route for indoor liners and disposable trays where impact strength is not critical.

Design notes

• 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
• plan the trim line on a flat face so the router can hold tolerance
• call out the finish on the drawing: mould texture, paint, or as-formed gloss

Finishing and assembly options

• mould texture
• soft touch coating
• as formed gloss
• 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. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• PPAP or ISIR on request
• material certificates with every batch
• UL94 V-0 grades 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

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.
