Company Milestone
In 1987, Cixi Wanji Electric Appliance Co., Ltd was established focusing on manufacturing toroidal iron core and toroidal transformer.
In 1997, Wanji was upgraded to Ningbo Wanji Electronics Science & Technology Co., Ltd. After 10 years of development, our new factory was founded, “Jishisheng” brand was awarded as “Ningbo Famous Brand” and “High-Tech Product of Zhejiang Province”. Wanji has become one of the leading toroidal transformer suppliers in China since then.
In 1999, Wanji passed ISO9002:1994 Quality Management System. We set up the Imp. & Exp. Dept. And succeeded in entering American and European markets.
In 2001, we started to design and manufacture EI power transformer and formed complete power transformer line.
In 2004, Wanji developed High Efficient Toroidal Transformer for Wind Energy Industry and exported to America Markets to become one of the earliest enterprise entering new energy industry in China. This year we passed UL structure and UL Insulation System approvals. Insulation System approvals.
In 2006, Wanji developed Toroidal Transformers for Solar Power Industry successfully. Meantime we followed RoHS Directives and used lead-free materials for power components.
In 2007, Wanji built a subsidiary company--Ningbo Zuoao Electronics Science & Technology Co., Ltd to engage in PCBA for Home Appliances and Equipment.
In 2008, Wanji was authorized with ISO14001:2004 Environment Management System.
In 2010, Wanji had built global customer group for various industries, the R&D ability was raised further.
In 2013, Wanji developed transformer for smart door & window systems to catch up with innovation trends.
In 2016, Wanji designed and developed special toroidal transformer for security & surveillance system to achieve better protection and less interference.
In 2018, Wanji introduced new automatic production equipment to reduce labor cost and increase the efficiency.
R & D and Productivity
R & D
Our R & D Dept. as one of core departments owns 40 engineers and technicians (6 senior engineers, 12 middle-level and 22 junior-level technicians). Using PROTEL and CAD S.W. for the design with the assistance of PE and IE Dept., your customized items can be well-realized here.
Wanji is cooperating with Corporate Management colleges such as Taiwan Jianfeng “Vigor Management Technology Academy”, Meijob and TBC, We invest USD$100,000 yearly on the employees’ career development training.
Productivity
Wanji has 15 Toroidal Transformer Production Lines (monthly productivity of 500,000pcs), 12 EI Transformer production lines (monthly productivity of 600,000pcs), and Toroidal Core monthly productivity of 600 tons. Reliable suppliers around and self-provision not only reduce the purchasing cost, but also shorten the procurement cycles. Global sourcing guarantees high volumes of material supplement and ensures to meet customers’ specification.
Quality Control & Conformity
Quality Control
Wanji Technology insists on the philosophy of “Customer-oriented, Quality cherished as life”. We have an 40-staff QC team and control the quality strictly under the systems of ISO9001 and ISO14001.Through setting up annual quality goals and monthly supervision, according to the “Quality Control Plan”and “FMEA” of each product, adopting SPC method, we ensure 100% testing and 100% outgoing quality rate. Meantime the Purchasing Dept., Accounting Dept., and R&D Dept., are implementing the ERP management.
