Key takeaway
Shuanglin Shares is progressing from developing robot screws and joint modules to securing customer nominations and producing in small batches, while expanding its upstream machine-tool capabilities. Further earnings growth depends on supplying products at scale.
How far have the robot products progressed?
Some miniature ball screw products for dexterous hands have secured customer nominations. The company has established machining capabilities and production lines, and has sent samples of products in various specifications to customers.
Products for humanoid robot linear-drive joint modules and inverted planetary roller screws have secured a nomination from a leading domestic new-energy vehicle maker and are currently in small-batch production. The first phase of the Ninghai Meiqiao plant has a production line with capacity for 100 thousand sets and is ready for mass production.
The nominations and production line lay the foundation for future supply, but a transition from current small-batch production to supply at scale is needed to potentially provide further support for the company's earnings growth.
What joint products can the company provide?
The company has developed linear and rotary joint modules, as well as dexterous hand and finger pushrod modules. It has end-to-end development capabilities for linear joint modules, from design and simulation to manufacturing, testing and validation.
Core components such as inverted planetary roller screws, frameless torque motors and motor drivers are developed in-house. The company is currently producing customized dexterous hand pushrod modules for a leading domestic new-energy vehicle maker and has also delivered multiple batches of prototypes to several robotics companies.
What has the machine-tool company acquisition changed?
In 2025, the company acquired all equity in Kezhixin, extending its business into grinding equipment upstream in the planetary roller screw supply chain. The materials state that this reduced equipment procurement costs and procurement lead times.
Kezhixin had limited production capacity in 2025, primarily serving internal needs. After its new plant enters production in June 2026, planned capacity for second-generation machine tools will exceed 40 units per month. The products and latest grinding technology will be sold externally, and several automotive, robotics and machine-tool screw customers have already booked sample production.
How is the low-altitude economy business progressing?
The company has planned a range of aircraft electric-drive products from 30 to 250 kilowatts. It has delivered an integrated 230-kilowatt electric propulsion system to a partner customer, while a 100-kilowatt product is scheduled for delivery in 2026.
