Tank Covers 6 mm polycarbonate Supplier for Water Treatment Equipment

These polycarbonate tank covers are thick gauge vacuum formed parts supplied to drawing for water treatment. They are formed from polycarbonate sheet at 6 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
• polycarbonate keeps the weight down while stiffness is held through the formed shape
• Silk screened markings 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
• material certificates with every batch

Typical applications

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

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
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. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.

Material: polycarbonate

Polycarbonate is used when the housing must survive impact or carry a glazing function. It must be dried before forming or the sheet will bubble.

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
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• plan the trim line on a flat face so the router can hold tolerance

Finishing and assembly options

• silk screened markings
• soft touch coating
• clear protective film
• 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. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• PPAP or ISIR on request
• REACH compliant sheet available
• food contact declarations available

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 10–15 working days, 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.

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.

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.
