polycarbonate Splash Guards Vacuum Formed in 10 mm for Hvac Equipment

These polycarbonate splash guards are thick gauge vacuum formed parts supplied to drawing for HVAC equipment. They are formed from polycarbonate 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
• polycarbonate keeps the weight down while stiffness is held through the formed shape
• Clear protective film 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

• duct end caps
• fan shrouds
• condensate trays
• unit covers
• splash guards used across general HVAC equipment builds

How it is made

1. Sheet is dried when the material needs it, then heated to forming temperature on the machine.
2. The part cools on a jig so the shape is held while the material stabilises.
3. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
4. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
5. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.

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

• avoid sharp steps in the mould, which show as chill marks on the finished surface
• 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
• use corner radii of at least three times the sheet thickness to avoid thinning

Finishing and assembly options

• clear protective film
• anti graffiti coating
• hot stamped accents
• 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.

• ISO 9001 quality system
• dimension reports with every release
• PPAP or ISIR on request

Packing and delivery

Parts are nested to save freight, with returnable dunnage available on repeat routes. Standard lead time to first article is 3–4 weeks, 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.

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.
