Flat workpieces are mostly processed by roller coating or curtain coating. Single-component water-based paint and UV paint are mainly applied via roller coating. For irregular / profiled workpieces, spraying is the preferred method, compatible with all types of coatings.

Common spraying processes include hanging spraying, robotic spraying and reciprocating spraying. Among them, reciprocating automatic spraying stands out as a high-efficiency coating solution and is widely adopted by manufacturers worldwide.

What Makes Reciprocating Automatic Spraying Rise Rapidly?

As the name suggests, reciprocating spraying relies on spray guns moving back and forth horizontally in a periodic cycle to apply paint onto workpieces. Its fast-growing popularity comes from three core advantages:

1. Higher Coating Efficiency

It features short conversion time, fast operation speed, accurate positioning and excellent reliability. The machine can store programs for more than 100 different products. Fitted with a rotatable material turntable, it enables convenient and safe loading and unloading, which saves production time and greatly improves working efficiency. Output: 120–180 trays per hour.

2. Stable & Superior Coating Quality

Controlled by a dedicated computer controller, the machine follows preset spraying paths precisely. It triggers spray guns accurately without offset, maintaining consistent coating thickness with tiny deviation. You can flexibly adjust air pressure, paint viscosity, gun flow rate and conveyor speed to meet different coating specifications. Stable coating performance pushes the product pass rate up to 99%. It is equipped with imported servo motors, Japanese PLC and human-machine interface, supporting programmable control for reliable and repeatable spraying results.

3. Lower Overall Operation Cost

Total coating cost covers equipment depreciation, maintenance, paint consumption, VOCs treatment and labor cost. Reciprocating spraying greatly cuts paint overspray waste and extends filter service life.

Manual spraying only reaches around 55% paint utilization rate, while reciprocating spraying hits 85%–95%, cutting paint consumption by roughly 30% compared with manual spraying. One reciprocating spraying line can replace around 12 spray painters, slashing labor cost by about 50% at the same production capacity. Thanks to high paint recovery rate, VOCs emission is reduced, fully complying with environmental regulations.

Smart & Modular Coating Solution

Modern reciprocating spraying systems adopt modular structure, unitized process design and intelligent data monitoring. It replaces unstable, high-pollution manual spraying workstations. You get boosted productivity, consistent coating quality, and real-time visibility of production data. It helps you build a fully automated, smart coating workshop.

Application Area

It is widely used in automotive interior parts, notebook computers, keyboards, television housings, DVD, MP4 and other similar products.
