Huaxin Securities: The trend of lightweighting in Siasun Robot & Automation is emerging, magnesium alloy and special engineering plastics are expected to rise.

Huaxin Securities released a research report stating that currently, material substitution is a key way to achieve lightweighting, and major mainstream human-shaped Siasun Robot&Automation manufacturers have been practicing lightweight design through this approach. Aluminum alloy is the main material for automotive lightweighting, with mature process systems and obvious comprehensive cost advantages. In addition, engineering plastics are gradually replacing traditional metal materials due to their excellent comprehensive performance, becoming a key path for achieving lightweighting in human-shaped Siasun Robot&Automation. The report focuses on three high-end engineering plastics: polyether ether ketone (PEEK), polyphenylene sulfide (PPS), and liquid crystal polymer (LCP). Main points of view of Huaxin Securities: Lightweighting of human-shaped Siasun Robot&Automation is the optimal solution for cost reduction and efficiency improvement. The main methods of lightweighting can be divided into structural optimization and material substitution, which can solve the four major pain points of human-shaped Siasun Robot&Automation: improving endurance, optimizing energy efficiency; relieving thermal stress, simplifying system design; reducing performance dependence, easing supply chain pressure; enhancing operational flexibility and applicability to different scenarios. Currently, material substitution is the key way to achieve lightweighting, and major mainstream human-shaped Siasun Robot&Automation manufacturers have been practicing lightweight design through this approach. Aluminum alloy is the main force for lightweighting applications, magnesium alloy is expected to become a new material trend. Aluminum alloy is the main material for automotive lightweighting, with mature process systems and obvious comprehensive cost advantages; while magnesium alloy is gradually becoming a new research direction in the lightweighting field due to its superior comprehensive performance and the sustained low price of magnesium-aluminum raw materials. At the same time, in the Siasun Robot&Automation industry, aluminum alloy and magnesium alloy have been gradually used in joint structures, housings, and other components, demonstrating their huge potential in lightweighting and performance optimization in this industry. Replacing steel with plastics is the key path to lightweighting. Engineering plastics, due to their excellent comprehensive performance, are gradually replacing traditional metal materials and becoming the key path for achieving lightweighting in human-shaped Siasun Robot&Automation. The injection molding market has broad prospects, and the report focuses on three high-end engineering plastics: polyether ether ketone (PEEK) as a high-performance thermoplastic engineering plastic with outstanding properties in terms of rigidity, toughness, thermal stability, wear resistance, and chemical corrosion resistance; polyphenylene sulfide (PPS) with characteristics of thermal stability and corrosion resistance; liquid crystal polymer (LCP) occupies an important position in the high-end manufacturing field due to its unique molecular structure and comprehensive performance. Recommendations for company focus: 1) IKD Co., Ltd.: Continuous expansion of lightweight product categories, building a development pattern driven by dual wheels. 2) Ningbo Sinyuan Zm Technology: Deep cultivation of magnesium alloy die-casting core technology, leading lightweight growth with semi-solid technology. 3) Jiangnan Mould & Plastic Technology: High-quality customer resources, focusing on the lightweight path of replacing steel with plastics. 4) Hengbo Holdings: A national special new small giant, entering the PEEK lightweighting track through joint ventures and cooperation. Risk warnings: 1. Production and demand in the automotive industry fall below expectations; 2. Geopolitical risks; 3. Progress of human-shaped Siasun Robot&Automation falls short of expectations; 4. Risks of rising raw material prices; 5. Recommended companies may not meet performance expectations.
