While Shanghai Shengpu's dispensing systems are preva- lent in the solar industry, its systems are also prominent in the gas and electronics industries. Shanghai Shengpu dispens- ing systems account for 80 percent of all solar panel bonding systems in China, helping to contribute to the $43 billion solar market, and several of its module manufacturing clients will be opening up facilities in the United States in the coming years. Pump upgrade Before Shanghai Shengpu took its dispensing systems to the solar panel market, it conducted an assessment of its existing equipment to conf irm that it was still working with the best products to develop its dispensing systems. Every solar panel plant conducts a process called "framing," where they attach an aluminum frame onto the solar panel. During framing, the dispensing system is used to lay down the sealant that adheres the aluminum frame to the glass panel. Shanghai Shengpu evaluated the fram- ing process and found that there was an opportunity to improve the existing sys- tem by incorporating a piston pump pack- Diagram provided by Shanghai Shengpu.
