OEM Equipment Covers LDPE in 5 mm for Hydroponics And Greenhouse

These LDPE equipment covers are thick gauge vacuum formed parts supplied to drawing for hydroponics and greenhouse. They are formed from LDPE sheet at 5 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
• LDPE 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
• dimension reports with every release

Typical applications

• seedling trays
• grow trays
• channel covers
• reservoir liners
• equipment covers used across general hydroponics and greenhouse 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. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
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. Sheet is dried when the material needs it, then heated to forming temperature on the machine.

Material: LDPE

LDPE is flexible and tough in thin section, used for liners and protective covers that have to bend during fitting.

Design notes

• hold the draw ratio near 1:1 for deep parts, or specify plug assist
• avoid sharp steps in the mould, which show as chill marks on the finished surface
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• use corner radii of at least three times the sheet thickness to avoid thinning

Finishing and assembly options

• anti static coating
• anti graffiti 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. Batch releases carry a dimensional report, material certificate and, where agreed, PPAP or ISIR documentation.

• UL94 V-0 grades available
• RoHS compliant grades available
• dimension reports with every release

Packing and delivery

Parts are stacked with interleaved film and packed in export cartons on pallets. 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

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.

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.
