Zibo Sunder Machinery Equipment Co., Ltd. was established in 2007, is a dedicated High-tech design, development, manufacture and marketing of High-tech enterprise. The company's business address is located in Zibo High-tech Business Estate, Zibo City, Shandong Province. There are 60 existing staff in the company, more than 90% are university qualifications. Our factory is located in Zi Chuan District, Zibo City, which is the home town of PU Songling, the king of short stories in the world. The factory site area is 2000 square meters, there are more than 30 production facilities. High-quality production and technical personnel, to ensure the company to provide, high-quality and stable products to our customers.
With " Science and Technology create future and Sincere serve customers" concept, based on market requirements, the company made deep research on the market, co-operated with domestic scientific research institutes, has developed SD10 and SD20 series Electric Program-controlled Screw Press. The Press is in the succession of domestic and foreign advanced technology, absorbed China's High-power Switched Reluctance Motor Drive System results, combined the requirements of Screw Press and advantages of Switched Reluctance Motor, made the reality of program and digital control of Screw Press, promoted the technological development of China's Press. Especially for the refractory industry, it is a technological revolution, which truly made a highly efficient energy saving and environment protecting, easily operation control, and good quality of products forming consistency.
Comparing to the old fashioned Friction Press, SD series Program-controlled Electric Screw Press has the following features and advantages:
1. The good quality of product forming and consistency with qualified rate. It can be
Digitally and programmable set the impacting power, make analog manual operation, first soft and then hard;
2. Accurately control the energy and hitting power, the Switched Reluctance Motor adjust speed in high precision, small error, and input energy of Press is accurate;
3. Short transmission chain, simple structure, small consumption parts and convenient maintenance in low cost. With no two friction discs, the motor drive flywheel directly in positive and inversed which make the slide move up and down to impact;
4. High degree automation which can reduce the manpower. Program-control the forming process, push-button operation, reduce the labor intensity;
5. Efficient and energy saving. The motor works when impacting, but when feeding, brick out and cleaning mold, the motor doesn't work. Compare to old style friction press, it can save energy about 30%--50%;
6. High safety. With three brake methods: Mechanical brake, Compressed air brake and Electric brake, and it also equipped with Emergency-stop button, which ensure the slide can be stopped at any position;
7. Reliable, safe and durable. The Switched Reluctance Motor has a soft-start feature, small current and large torque which can reduce the impact to the grid. The strong structure of motor rotor, it can withstand the impact load, the block up and lack of phase will not burn the motor and controller.
