Seat Shells recycled HDPE in 3 mm for Garden And Outdoor Power Equipment – Formed to Drawing

These recycled HDPE seat shells are thick gauge vacuum formed parts supplied to drawing for garden and outdoor power equipment. They are formed from recycled HDPE sheet at 3 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
• Anti graffiti coating 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

• engine covers
• mower decks
• grass catcher shells
• tool trays
• seat shells used across general garden and outdoor power equipment builds

How it is made

1. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
2. The part cools on a jig so the shape is held while the material stabilises.
3. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• anti graffiti coating
• matte finish
• mould texture
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• UL94 V-0 grades available
• dimension reports with every release
• material certificates with every batch

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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

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.

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.
