OEM Sign Faces HDPE in 8 mm for Food Processing

These HDPE sign faces are thick gauge vacuum formed parts supplied to drawing for food processing. They are formed from HDPE sheet at 8 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
• 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
• dimension reports with every release

Typical applications

• washdown panels
• conveyor guards
• mixer covers
• product trays
• sign faces used across general food processing builds

How it is made

1. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
2. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
5. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.

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

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• 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

• silk screened markings
• matte finish
• 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.

• UL94 V-0 grades available
• dimension reports with every release
• ISO 9001 quality system

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. Standard lead time to first article is 7–15 working days, 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.
