,位于成都市新都老工业园区,注册资金500万元,总投资1000余万元,占地面积近万平方米,现有职工100余名,其中高中级科研人员占员工总数的30%,年生产能力达5000余台(套)。 Chengdu Duolin Electric Co. , Ltd. is located in Xindu Old Industrial Park, Chengdu, with a registered capital of 5 million yuan, a total investment of more than 10 million yuan, an area of nearly 10,000 square meters, and more than 100 employees, including high- and intermediate-level scientific research personnel. 30% of the total, with an annual production capacity of more than 5,000 units (sets).  

The founder Zeng Xiaolin, graduated from Chongqing University, founded Chengdu Duolin Electric Appliance Factory in 1996, and established Chengdu Duolin Electric Co., Ltd. in 2002. For more than ten years, Dorin has been committed to the research and development and production of IGBT series induction heating equipment, independently developed and produced power from 2KW to 1500KW, frequency from 0.5KHz to 1.2MHz, and passed ISO9001: 2015 quality system certification. Doolin developed MFP-type intermediate frequency series induction heating equipment, HGP-type (ultra-high-frequency) series, HFP-type high-frequency series, SSF-type super audio low-power series, SSF-CH type super audio high-power series and intelligent high-frequency multi-frequency Multi-pot melting sample equipment and complete sets of equipment (such as hot perforation on-line equipment, on-line quenching and tempering heat treatment equipment, rivet heating furnace, etc.) are widely used in forging hot forming, pipe bending, welding, heat treatment, precision casting, melting, packaging and packaging Other heating areas. The main features of the IGBT induction heating equipment produced by our company are: small equipment size, fast heating speed, high efficiency; 20-50% power saving compared with high-frequency tube machine, 10-30% energy saving compared with old-style SCR equipment; Various protection functions such as over-current, over-voltage, over-heating, etc., are easy to operate and easy to install, and are suitable for various occasions where metal heating is required. The induction heating equipment produced by our company is called "all solid-state induction heating equipment" because the power devices are all semiconductor devices, which are commonly known as intermediate frequency furnaces, high frequency machines, high frequency welding machines, induction heating machines, etc.

In 2009, the company shifted its products to complete sets, users of large and medium-sized enterprises, and took the path of professional support. The product specifications are complete, the scope of application is wide, and the reliability is high. The products cover more than 20 provinces and cities.
