Dongguan Jinjiu Automation Technology Co., Ltd.

Dongguan Jinjiu Automation Technology Co., Ltd. (hereinafter referred to as "Jinjiu Technology") is based in Dongguan, the core hinterland of the Guangdong Hong Kong Macao Greater Bay Area. As a national high-tech enterprise, the company focuses on the entire industry chain of research and development, production, sales, and services, and is committed to becoming a leading enterprise in the field of global plastic film intelligent equipment.
After fifteen years of continuous cultivation, Jinjiu Technology has built a technology matrix with online thickness measurement automatic wind ring system as the core, forming a three in one solution system of "hardware equipment software algorithm intelligent control". The AI intelligent closed-loop control technology independently developed by the company breaks through the limitations of traditional blown film processes that rely on manual experience. Through multi-sensor data fusion and machine learning algorithm optimization, it achieves a precision of film thickness deviation control of ≤± 1.5%, which is more than 40% higher than the industry average level.
As of 2025, the company has established a 3000 square meter R&D center and a 20000 square meter intelligent production base, and has obtained a total of 32 national patents (including 7 invention patents). It has also passed ISO9001 quality management system, CE safety certification, and intellectual property management system certification. Relying on a global service network, Jinjiu Technology has provided customized solutions to over 300 customers in more than 20 countries and regions including China, Southeast Asia, Europe, and the Americas, helping customers achieve significant benefits such as a 25% increase in production efficiency and an 18% reduction in material loss.

Online thickness measurement automatic wind ring system - the "smart brain" of blown film technology

Jinjiu Automation has built an industry-leading one-stop closed-loop control system based on its independently developed three core modules: automatic air ring control system, high-precision thickness gauge, and intelligent software control system, providing comprehensive guarantees for film thickness uniformity, production stability, and raw material utilization.

1. Originating from the German WH dual lip high-yield automatic wind ring design concept - intelligent automatic wind ring
Adopting multi zone independent closed-loop control technology, real-time dynamic adjustment of air volume, and rapid response to membrane bubble fluctuations
Patent air duct design ensures uniform airflow and effectively solves the pain points of traditional air ring adjustment lag and dependence on manual experience.

2. German leading blown film machine manufacturers such as WH and Alpina use the same thickness gauge - high-precision online thickness gauge
Based on non-contact scanning measurement technology, with a resolution of 0.1 μ m, the film thickness can be monitored in real-time across the entire range
Compatible with multi-layer co extrusion process, suitable for various materials such as PE, PP, PVC, etc., with precise and stable data.

3. Intelligent control system
Equipped with autonomous algorithms, it achieves millisecond level linkage between thickness data and wind ring adjustment, dynamically optimizing production processes
Support historical data traceability, self-learning of process parameters, and remote operation and maintenance, empowering the construction of digital factories.

✅ Leading the way: Our R&D team has over 10 years of industry experience and our core technology has obtained multiple national patent certifications.
✅ Quality commitment: The core components are made of imported electronic components and have passed ISO9001 quality management system certification

✅ Cost reduction and efficiency improvement: Improve thickness uniformity by over 50%, reduce raw material waste by 15% -25%, and help customers enhance competitiveness.
✅ Worry free service: providing customized solution design, installation and debugging, and 24-hour response services to fully escort customer production.

With the concept of "intelligent manufacturing precision, defining the future", Jinjiu Automation will continue to innovate, promote the intelligent upgrading of the blown film industry, create more efficient and environmentally friendly production value for customers, and become a trusted partner in the global film manufacturing field!
