Accurate on-ratio mixing for Vovlo Construction Equipment in Korea

Volvo Korea, a manufacturer of excavators and dump trucks, is headquartered in Asia Pacific and supports regional factories in China and India.

Volvo Korea had used a one-component airless pump with AA gun to apply the primer and topcoat to excavator frames. Six pumps were installed. Every day, operators had to flush all pumps after spraying, which wasted a lot of mixed material and solvent. Operators frequently mixed material manually during work as well – up to four or five times per day. The working environment needed to be improved. The challenge: how to increase working efficiency while saving solvent and material.

Intorudcing new technology

Local Graco distributor suggested a Graco XM™ Plural-Component Sprayer. XM’s dosing technology assures accurate, on-ratio mixing for better yield and less waste. Besides, each XM50 has a maximum flow rate at 3 gpm which can support multiple guns. Advanced, intuitive user controls provide real-time display of the spraying ratio, and the USB port lets users easily access and download historical spraying data. In general, the XM can ease the operator’s work and increase working efficiency.

Field test

Graco held a field test at the Volvo Korea's job site which impressed the operators. The next step was to present the technology to Volvo Korea's management team. The assumed annual material and solvent savings impressed the customer. It means the payback period is less than eighteen months which convinced the management team to purchase the XM.
 

Precise ratio control

With the Graco XM50, Volvo Korea not only improved its manufacturing process but also increased productivity by eliminating material hand-mixing and daily equipment flushing. Moreover, the equipment provides precise ratio control which meets Volvo Korea's requirement. The good results convinced them to invest in two more XM50 sprayers after the first order.
