Home › Spray Coating Machines
Spray coating machines differ mainly in how the gun moves. This page compares the Lynvex axis, reciprocating and mini machines so you can match the motion to your part shape, batch size and line layout before asking for a quote.
A single-axis machine moves the gun back and forth over flat parts. A three-axis machine adds vertical and depth movement for simple three-dimensional parts. Five-axis and six-axis machines add gun angling and rotation, which keeps the gun at the right distance and angle on complex housings, doors and moulded parts. Reciprocating machines carry the same back-and-forth motion onto a conveyor line, and mini rotary machines turn small parts under a fixed gun for short runs and trials.
| Machine type | Gun motion | Best-fit parts |
|---|---|---|
| Single-axis | Reciprocating stroke over the part | Flat panels, glass, boards, simple flat parts |
| Three-axis | X / Y / Z movement | Phone and hardware parts, simple 3D shapes |
| Five-axis | X / Y / Z plus gun tilt and rotation | Plastic and metal housings, laptop shells, helmets |
| Six-axis | Full articulated gun movement | Wood doors, complex moulded parts |
| Reciprocating (online) | Stroke motion over a moving conveyor | Flat parts in continuous line production |
| Mini rotary | Part rotates under a fixed gun | Small parts, samples, trial production |
Part size sets the working envelope; coating type sets the booth and curing pairing; batch rhythm decides between a stand-alone machine and a conveyor-fed one. Epoxy, PU and water-based paints all run on the same machine families, but the booth extraction and curing sections differ, so name your coating in the inquiry. If your parts change shape often, favour more axes; if they never change, a simpler machine is cheaper to run and maintain.
Axis spray machines serve production where the same part repeats thousands of times: consumer electronics housings, helmets and protective gear, sanitary ware, toys and moulded plastic or metal components. The economic logic is repeatability — once the gun path, distance and speed are set for a part, every cycle repeats them, so film thickness stays even and paint consumption per part can be measured and tuned.
Two operating habits decide results more than the machine class does. First, fixture design: a part that sits 2 mm differently each cycle sprays differently each cycle. Second, gun maintenance: a worn nozzle changes the fan pattern long before it fails outright, so nozzle checks belong in the weekly routine. Both points are covered when a configuration is commissioned.
An axis machine is one station in a process. Upstream, parts usually need cleaning or electrostatic dust removal, especially moulded plastics that carry static. Downstream, the coating decides the next step: air-dry paints need flash-off space, baked enamels need an oven, UV coatings need a curing section. When you request a quote, name the equipment you already own for these stages; the machine will be specified to feed it, including conveyor height and part hand-off.
A five-axis machine is the usual compromise: it handles flat parts easily and still follows moderate 3D shapes. Send drawings of your most complex part and we will confirm.
