Door Panels 12 mm HDPE Supplier for Water Treatment Equipment

These HDPE door panels are thick gauge vacuum formed parts supplied to drawing for water treatment. They are formed from 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
• 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
• ISO 9001 quality system

Typical applications

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

How it is made

1. The part cools on a jig so the shape is held while the material stabilises.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

Material: HDPE

HDPE is chosen for chemical resistance and impact strength at low temperature. It needs more heat and a longer cooling cycle than ABS, and it is painted only after flame or plasma treatment.

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
• 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

Finishing and assembly options

• anti graffiti coating
• pad printed logos
• 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.

• PPAP or ISIR on request
• 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

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.

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.
