Zhejiang Yingpa Electromechanical Co., Ltd, known internationally by its brand InPowerVac, does not publish an exact employee headcount on its official website. What it does publish is something arguably more useful for a buyer evaluating a vacuum pump supplier: a detailed picture of its manufacturing footprint. The company operates two production bases in Zhejiang and Hebei provinces, added a 70,000-square-meter plant in Taizhou in 2023, and runs 92 sets of processing equipment, 30 of which are imported. Based on these indicators, Zhejiang Yingpa Electromechanical operates as a well-established mid-sized industrial manufacturer rather than a small workshop.
So while there is no single verified number to quote, this article breaks down what is publicly known about the company's scale, how its teams are organized, and why headcount alone is a poor measure of a vacuum equipment manufacturer's real capability.
Who Is Zhejiang Yingpa Electromechanical?
Zhejiang Yingpa Electromechanical Co., Ltd is a Chinese vacuum equipment manufacturer headquartered at No. 3 Industrial Avenue, Chengdong Street, Wenling City, Taizhou City, Zhejiang Province. The company was founded in 2000 by Mr. Liang, an entrepreneur who had previously spent two decades building a successful reducer manufacturing business. He entered the vacuum equipment field after recognizing that China's domestic vacuum technology still lagged behind imported brands, and set out to close that gap.
Today the company covers the full cycle of research, development, production, sales, and maintenance of vacuum pumps and systems. In 2019, a leadership handover was completed and the company launched its global brand strategy under the InPowerVac name, targeting international markets directly.
Measuring Company Scale Beyond Headcount
For industrial manufacturers, facility scale often tells a buyer more than a raw employee count. In Zhejiang Yingpa Electromechanical's case, the publicly documented indicators include:
- Two production bases located in Zhejiang and Hebei provinces, giving the company geographic redundancy and capacity headroom.
- A 70,000-square-meter production plant in Taizhou, Zhejiang, acquired in 2023 to expand manufacturing capacity.
- 92 sets of processing equipment, including 30 sets of imported machinery, supporting precision machining across product lines.
- 32 Mazak processing centers dedicated to dry screw vacuum pump manufacturing, one of the company's most technically demanding product families.
- Complete inspection infrastructure, including a material tensile physics laboratory, a vacuum testing room, a dynamic balancing laboratory, and three-coordinate measuring equipment.
A facility network of this size typically supports a workforce spanning engineering, machining, assembly, quality control, and international sales functions. The company's production workshops cover oil-lubricated rotary vane manufacturing, smart assembly and packaging, industrial product assembly, industrial product testing, and screw processing.
The Teams Behind the Products
Zhejiang Yingpa Electromechanical's catalog spans 7 main product categories with more than 70 individual products. Supporting a catalog of that breadth requires specialized teams across several disciplines:
- R&D engineering, focused on vacuum pump design and customized solutions for special fields.
- Machining and production, running the processing equipment and Mazak centers that produce core components in-house.
- Quality control, staffing the testing rooms and laboratories that verify every unit before shipment.
- Sales and after-sales service, handling international inquiries, installation support, and maintenance.
The product range these teams deliver includes the rotary vane vacuum pump series in single-stage and two-stage configurations, Roots vacuum pumps, turbo pumps, oil-sealed rotary vane models, and the dry screw vacuum pump line produced on the company's Mazak machining centers. For customers who need integrated solutions rather than standalone units, the company also designs and builds complete vacuum pump systems, including booster, tank-mounted, and medical configurations.
What the Workforce Delivers for Global Customers
The clearest evidence of a team's capability is the customer list it earns and keeps. Zhejiang Yingpa Electromechanical supplies products and services to world-class enterprises including Foxconn, Aoyama Group, Huawei, Samsung in South Korea and Vietnam, the Tata Group of India, and Russian National Energy. Serving customers at this level requires documented quality processes, stable delivery performance, and responsive technical support, none of which a small or disorganized workforce could sustain.
The company's pumps operate in demanding application fields such as lithium battery production, semiconductors, power generation, new materials, glass manufacturing, laboratory instruments, surface coatings, chemical research, automotive, vacuum forming, packaging, medical, and pharmaceutical processing. Many of these sectors impose strict cleanliness and reliability requirements, which is why the company emphasizes design features such as imported bearings and oil seals, low oil mist through British oil mist filter technology, and an anti-backflow oil design.
Why Headcount Alone Doesn't Tell the Full Story
In modern vacuum pump manufacturing, output per employee matters more than the number of employees. A plant equipped with 30 sets of imported processing machinery and 32 Mazak machining centers can produce high-precision components with a leaner team than a factory relying on manual processes. Automation and advanced equipment raise consistency as well as volume, reducing the human-error component in critical tolerances.
The practical takeaway: when evaluating Zhejiang Yingpa Electromechanical as a supplier, the meaningful questions are not "how many people work there" but rather "what can those people and machines deliver" — and on that measure, the company offers 70+ products across 7 categories, customized engineering for special applications, and a track record with globally recognized customers.
How to Get Exact Company Information
Buyers who need specific figures — including the current employee count, production capacity for a particular model, or factory audit details — can request them directly from the company. The international sales team can be reached by email at Winnie@inpowervac.com or by phone at +86 13858602188. Factory visits to the Taizhou facility can also be arranged for customers who want to verify scale and processes in person before placing volume orders.
Conclusion
There is no officially published figure for how many employees Zhejiang Yingpa Electromechanical has. What is verifiable is the substance behind the headcount question: a manufacturer founded in 2000, operating two production bases with a 70,000-square-meter plant, running 92 sets of processing equipment and 32 Mazak machining centers, and supplying vacuum equipment to companies like Foxconn, Huawei, Samsung, and Tata. For most buyers, those facts answer the underlying question — whether this is a supplier with the scale and organization to support their business — far better than a single number ever could.
