Protective Guards 12 mm recycled HDPE Supplier for Water Treatment Equipment

These recycled HDPE protective guards are thick gauge vacuum formed parts supplied to drawing for water treatment. They are formed from recycled HDPE sheet at 12 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 static 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

• dosing tank liners
• control panel shells
• channel covers
• filter housings
• protective guards used across general water treatment builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
3. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
4. The part cools on a jig so the shape is held while the material stabilises.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

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

• use corner radii of at least three times the sheet thickness to avoid thinning
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• anti static coating
• two coat polyurethane paint
• as formed gloss
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample. Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report.

• material certificates with every batch
• REACH compliant sheet available
• RoHS compliant grades available

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

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.

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.
