Powder coating lines and spraying equipment

Complete electrostatic powder coating lines and the equipment around them — pre-treatment, spray booths, recovery, powder supply, automatic spraying and explosion protection. Supplied from our partner factory in Changzhou, built to your workpiece size and output.

Complete line

One line, from shot blasting to curing

You do not have to assemble a coating line from five different suppliers. We quote the whole sequence as one package, and you keep one contact for the spares afterwards.

  • Shot blasting & pre-treatment
  • Powder spray booth
  • Cyclone recovery & filtration
  • Powder supply centre
  • Reciprocators or robot spraying
  • Curing oven
  • Overhead conveyor / power & free
  • Explosion protection & control
Throughput, conveyor speed, line length and power depend on your workpiece and target output per shift — we size the line from your drawing, so nothing is over- or under-specified.

Spray booths

Powder spray booths

Booths are where most line problems start, so this is the part we spend the most time on. Arc panels on four sides and the roof cut the cleaning time between colour changes; a dual extraction base keeps airflow even, lifts powder transfer efficiency and stops powder drifting out of the opening.

Sandwich arc powder spray booth with cyclone

Sandwich arc booths

Open-type or dual-station, for flat panels and medium parts. Quick colour change is the point of this design.

Custom width & length
Walk-in spray booth with cyclone and filter unit

Walk-in & large-part booths

For very large or heavy workpieces that are conveyed through on a hanger, with operator access inside the booth.

Up to very large parts
Stainless steel cyclone filter with explosion venting

Explosion-proof versions

Flame-retardant PPS panel construction, stainless steel cyclone and explosion venting as one package.

ATEX-style safety layout
Recovery & separation

Cyclone recovery and explosion-proof filtration

Powder that is recovered cleanly is powder you do not buy twice. The cyclone takes the bulk of the reclaim, the precision filter catches the fine fraction, and the safety devices keep the whole system within its explosion limits.

Large cyclone separators

High-efficiency single or multi-cyclone, carbon steel or stainless steel, sized to your extraction volume.

Precision explosion-proof filters

Second-generation arc-shaped filter modules, designed for quick cartridge change and easy cleaning.

Vacuum closed-loop pump

For closed-loop powder systems where the reclaim is fed straight back to the hopper.

Powder supply

Powder supply centres and colour change

Where a line runs one colour, a standard hopper is enough. Where it runs several, the supply centre is what decides how long the changeover takes.

Powder supply and spray station at the test bay

Quick colour change centre

Multiple hoppers with fast switching, so a colour change does not stop the line for the whole shift.

Multi-colour lines

Closed supply centre

Sealed powder path for better hygiene and less dust in the working area — useful where operators are close to the booth.

Sieving & fluidising units

Sieves, hoppers and pumps sized to the guns and the recovery rate of your line.

Automation

Automatic spraying and control

Start with manual guns and add automation later — the line is built so that reciprocators, recognition and robots can be introduced without rebuilding the booth.

Automatic spraying reciprocator

Reciprocators & robots

Top and bottom spraying with inversion, four-dimensional reciprocating machines, short-stroke units and robot booths.

Manual → fully automatic

Recognition systems

Workpiece recognition, gap detection, measuring light curtains and laser scanning — the gun only sprays where there is a part.

Intelligent control cabinet

Line control, recipes and diagnostics in one panel, with the safety chain wired into the same cabinet.

Safety

Explosion protection

Powder is a combustible dust, so this is the part of the line that gets checked at acceptance — and the part that most suppliers quote loosely. Ours is a package: detection, isolation, venting and suppression.

Questions buyers ask

Powder coating line FAQ

How long does a colour change take?

It depends on the booth type and how many colours you run. The sandwich arc booth with a quick-change supply centre is designed for frequent changes; we quote a realistic changeover time for your line rather than a marketing number.

What do you need from us to quote?

Workpieces (drawing or photos), maximum size and weight, target output per shift, powder type and number of colours, available floor space and power supply. With those we can size the line.

Is the line explosion-proof?

Yes — detection, isolation, venting and suppression are quoted together with the booth and the recovery unit. The control panel and detector specification is listed in the table above.

Can we start manual and automate later?

Yes. The booth and recovery unit are sized so that reciprocators, recognition systems or robots can be added without replacing them.

What is the delivery time?

Typically 45–90 days depending on line size, plus shipping. We give you a written schedule with the quotation.

Who installs and commissions it?

We supply drawings, remote guidance and, if needed, arrangement of a commissioning engineer. Tell us your site conditions when you enquire and we will quote the options.
