Breaking Technical Barriers: China Achieves Autonomous Control of Core Injection Molding Machine Components

China’s injection molding industry has long been constrained by reliance on imported core components—until now. In 2024, domestic manufacturers achieved a milestone: 85% localization rate for high-precision hydraulic systems, servo motors, and control systems, up from 32% in 2018 (CCID). This breakthrough, driven by $12 billion in R&D investment over five years, is reshaping global supply chains and positioning China as a leader in smart manufacturing. This article explores how homegrown innovation is overcoming technical bottlenecks and enabling "Made in China 2025" ambitions.

 

• Until 2020, 90% of high-end hydraulic systems in China’s top 100 molders came from Bosch Rexroth and Parker Hannifin.
• Cost Impact: Foreign components added 30–40% to machine prices.

2. Performance Deficits

 

• Domestic servo motors lagged foreign counterparts in precision (±0.01mm vs. ±0.005mm) and energy efficiency (IE3 vs. IE5).

3. Intellectual Property Constraints

 

• Key patents for injection control algorithms were held by German and Japanese firms, limiting customization.

II. Pathways to Autonomous Control

1. Hydraulic System Revolution

 

• New Technology: Zhejiang Haitai’s HT-Flex series reduces energy consumption by 28% through variable displacement pumps.
• Market Impact: Captured 45% of China’s 1,000+ tonnage machine market in 2024.

2. Servo Motor Breakthrough

 

• Ningbo Techmation’s NT-Servo: Achieves ±0.007mm positioning accuracy, matching Japanese competitors at 60% of the cost.
• Customer Case: Guangdong Zhenxiong uses NT-Servo in EV battery tray molding, cutting rejects by 22%.

3. AI-Powered Control Systems

 

• Guangdong Yizumi’s iPower 5.0: Integrates predictive analytics to optimize pressure and temperature in real time.
• Result: Shortens trial runs from 8 hours to 2.5 hours.
