Why do humanoid robots need PEEK?

  • Humanoid robots have greater requirements for lightweight construction and resistance to wear than traditional industrial robots. Reducing weight can improve payload capacity, battery life and flexibility, and may also drive demand for materials such as specialty engineering plastics.
  • PEEK combines rigidity, toughness, heat resistance and wear resistance. Pure resin has a density of about 1.3 grams per cubic centimeter and can be processed into parts of different shapes, making it suitable for specialized components or operating conditions. Zhao Naidi of Everbright Securities is therefore optimistic about the PEEK sector.
  • The demand opportunity depends on the pace of robot adoption: China's Ministry of Industry and Information Technology forecasts that domestic production of complete robots could exceed 100 thousand units in 2026; Omdia expects global sales to rise from more than 13 thousand units in 2025 to 605.7 thousand units in 2030. Applications of the material also face risks from alternative technologies and slower-than-expected adoption.

How fast are Ampron's new pressure sensor products growing?

  • In the first half of 2026, Ampron's MEMS pressure sensor revenue was 53.8981 million yuan, up 120.45% year over year. Its products have entered the supply chains of customers including Stellantis and SAIC Maxus.
  • However, overall pressure sensor revenue in the same period was 301 million yuan, up just 2.91% year over year. Xiao Qunxi of Guotai Haitong Securities expects cost reductions for ceramic capacitive products, together with the ramp-up of new MEMS and glass micro-melt products, to return the segment to faster growth.
  • Glass micro-melt pressure sensors entered mass production and delivery in April 2026, covering medium- and high-pressure applications such as automotive rail pressure, suspension and EHB braking. The products have also secured designated supplier status from a well-known European parts manufacturer and leading domestic new-energy vehicle makers, opening up new applications for the business.

How does investment in force sensors affect the earnings outlook?

  • Ampron completed a private placement in August 2026, raising net proceeds of 534 million yuan for force sensors and capacity construction. Its six-axis force, torque, and tension and compression sensors for robots have already been delivered in batches.
  • The company's two sensor technology approaches can be used in humanoid robots. Xiao Qunxi believes faster industrialization could generate additional orders, but the absorption of new capacity remains a key condition.
  • Xiao Qunxi forecasts net profit attributable to the parent of 23 million, 67 million and 136 million yuan, respectively, for 2026 through 2028, and sets a target price of 80.09 yuan based on the average of valuations using a 80 times price-to-earnings ratio and a 5.5 times price-to-sales ratio for 2028.
