5 mm LDPE Seat Shells Manufacturer for Industrial Robotics

These LDPE seat shells are thick gauge vacuum formed parts supplied to drawing for industrial robotics. 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
• Mould texture 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
• REACH compliant sheet available

Typical applications

• robot base covers
• controller housings
• cable trays
• teach pendant cases
• seat shells used across general industrial robotics builds

How it is made

1. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
2. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
3. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
4. Trimming is done on 5-axis routers or with a dedicated trim fixture to meet the drawing.
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
• call out the finish on the drawing: mould texture, paint, or as-formed gloss
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• hold the draw ratio near 1:1 for deep parts, or specify plug assist

Finishing and assembly options

• mould texture
• pad printed logos
• 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
• material certificates with every batch
• REACH compliant sheet 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

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.

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.
