I. PLC: Xinjie and Huichuan
For PLC cost-effectiveness, consider Xinjie and Huichuan. According to industry reviews, Xinjie Electric is known as the “Wuling Hongguang” of the industrial control industry, offering the cheapest, easiest-to-use, and most widely used PLCs in small equipment.
Its price is about half that of Mitsubishi, and it holds the second-largest domestic market share in small PLCs. Huichuan Technology is a leading domestic industrial control company, holding the number one domestic market share in general-purpose servo systems, covering all sizes of PLCs, and boasting a complete software and hardware ecosystem.

Servo Systems: Huichuan and Leisai
For servo and motion control, consider Huichuan, Leisai, and Weichuang.
According to industry data, Huichuan servo motors can directly replace Yaskawa, Panasonic, and Mitsubishi servo motors, with similar parameters and logic; switching is only required with minor wiring modifications. Leisai Intelligent is a leader in the precision motion control segment, achieving nanometer-level precision in both stepper and servo motors. Weichuang Electric’s high-performance, cost-effective medium-to-high-power servo solutions are significantly cheaper than overseas brands while maintaining comparable performance, and have a good reputation in the crane, fan, and lithium battery sectors.
**III. Low Voltage: Chint and Delixi**
For low-voltage electrical appliances, Chint and Delixi are recommended.
According to control cabinet manufacturers’ experience, imported low-voltage components use Schneider Electric, which is expensive; for domestic components, Chint and Delixi are preferred due to their lower prices, ease of procurement, and wide retail channels. They offer a full range of products including circuit breakers, contactors, and relays, suitable for general equipment and complete enclosures.
For intermediate relays, Omron or Izumi can be considered.
**IV. Sensors: Hikvision**
For sensors, Hikvision and other domestic brands are recommended.
According to industry analysis, Japan has Keyence, and China has Hikvision—domestic products are now comparable in the machine vision and sensor fields. For pressure sensors, domestic companies like Shanghai Zhaohui and Anhui Qidian cover the petrochemical, new energy, and pharmaceutical industries, with prices significantly lower than imports.
For workstations requiring accuracy of ±0.05mm, domestic sensors are perfectly adequate.
V. FA Standard Parts: Yiheda
For FA standard parts, consider Yiheda, Shanglong, and Sanyi.
According to industry data, Yiheda has over 2.8 million SKUs, a complete range, and ample stock. Shanglong is cheaper and a more cost-effective domestic alternative. Sanyi Precision has over 3 million SKUs, with prices 30%-50% lower than international prices. Based on purchasing experience, using domestically produced, economical models can reduce costs by approximately 25%. Shaft supports, linear bearings, springs, and locating pins are interchangeable with MISUMI models.
Conclusion
The core principle for recommending cost-effective brands of automation equipment components is “domestic brands + workstation tiers”: Choose Xinje for PLCs, Huichuan for servo drives, Leadsai for motion control, Chint and Delixi for low-voltage systems, Hikvision for sensors, and Yiheda and Shanglong for standard FA parts—replacing imported components with imported ones for ordinary workstations can save 30%-50% in costs; however, it is not recommended to arbitrarily replace them for high-speed, heavy-duty, and high-precision critical workstations.
For detection scenarios with an accuracy of ±0.01mm, imported components should still be chosen.
Cost-effectiveness is not about the cheapest being the best, but about spending money on critical workstations.
