4 mm HIPS Wheel Covers Manufacturer for Playground Equipment

These HIPS wheel covers are thick gauge vacuum formed parts supplied to drawing for playground equipment. They are formed from HIPS sheet at 4 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
• Soft touch 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
• ISO 9001 quality system

Typical applications

• climbing tower caps
• slide shells
• panel covers
• seat buckets
• wheel covers used across general playground equipment builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.

Material: HIPS

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

Design notes

• 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
• 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

• soft touch coating
• mould texture
• matte 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.

• ISO 9001 quality system
• food contact declarations available
• dimension reports with every release

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

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.

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.
