Thick Gauge LDPE Plastic Enclosures in 10 mm – Solar And Wind Energy Range

These LDPE plastic enclosures are thick gauge vacuum formed parts supplied to drawing for solar and wind energy. They are formed from LDPE sheet at 10 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
• 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

• cable covers
• inverter covers
• combiner box housings
• nacelle access panels
• plastic enclosures used across general solar and wind energy builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
4. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
5. The part cools on a jig so the shape is held while the material stabilises.

Material: LDPE

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

Design notes

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• use corner radii of at least three times the sheet thickness to avoid thinning
• plan the trim line on a flat face so the router can hold tolerance
• add ribs or returns instead of increasing sheet thickness to save weight and cycle time

Finishing and assembly options

• silk screened markings
• mould texture
• UV stabilised as formed
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch. First article inspection covers critical dimensions, wall thickness, colour and texture against the approved sample.

• material certificates with every batch
• food contact declarations available
• dimension reports with every release

Packing and delivery

Large panels are crated in made to measure wooden cases with corner protection. 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.
