Founded in 2017, Xinyu has become a recognized specialist in the industry, specializing in large-scale integrated die casting body thermal management systems and achieving remarkable results in the R&D and manufacturing of temperature control equipment. The company’s independently developed temperature control products hold a strong position in the Chinese market with some of the most comprehensive product range. These include high-pressure spot cooling machines, mold-side cooling units, mold cooling machines, water-based mold temperature controllers, oil-based mold temperature controllers, contour spraying systems, pure water treatment systems, and integrated piping systems. Together, they meet diverse temperature control needs across different customers and application scenarios.
Since its establishment, Xinyu Intelligent has focused firmly on the die casting industry. With strong technical expertise and innovative capabilities, it has built a complete one-stop service system for large-scale mold temperature control solutions. This system integrates mold design, die casting processes, contour spraying, and vacuum assistance to provide customers with comprehensive solutions from design planning to on-site implementation.
Donglin is a professional company specializing in the design and manufacture of high-precision medium and large-scale thermal balance die casting molds, covering a range of 800T–12000T. The mold workshop covers 6,600㎡, with a total plant area of 25,000㎡. The company combines mold design with temperature control systems, dedicated to improving the qualification rate of automotive die castings, reducing production cycle times, lowering energy consumption, extending mold life, and increasing mold utilization rates.
Donglin Precision is a subsidiary controlled by Xinyu Technology. Its original purpose was to integrate years of temperature control experience and accumulated database resources into mold design from the early stages of development. After mold delivery, professional die casting process engineers and production staff accompany customers in actual production, creating a unique delivery method that brings added value to the industry.
In the field of mold temperature control technology research, the company has a professional team of engineers and R&D specialists who continue to explore and innovate, committed to overcoming technical challenges. After extensive testing and continuous improvements, the products have achieved remarkable results in large-scale practical applications.
For example, the company successfully developed the Autonomous ThermLoop System for intelligent closed-loop mold temperature control. This system uses the mold infrared sensing system (MISS) to monitor mold temperature in real time, while collecting pipeline data from various temperature control devices to generate comprehensive feedback. The data is transmitted to the “temperature control brain” — the ThermLoop algorithm. Based on heat transfer principles and intelligent technology, the algorithm compares actual temperatures with preset targets, calculates the required adjustment parameters, and verifies their accuracy. the centralized mold temperature control system (CTCU) then sends the parameters to each temperature control device, which adjusts the physical parameters of the heat transfer medium in the pipelines to precisely add or remove heat, thus achieving accurate mold temperature control.
This system marked the first successful realization of fully automated closed-loop autonomous mold temperature control in real die casting scenarios. Compared with manual control, it reduced die casting cycle time by 15%–30% while maintaining product qualification rates, significantly shortening spraying and air-blowing times and greatly improving production efficiency.
In addition, the company developed the CTM large high-temperature water circuit control system. A single CTM can replace more than ten traditional water temperature machines within a temperature control unit group, making ultra-large die casting island temperature control units more compact, cost-effective, energy-efficient, and precise. The CTM adopts a split-structure design, with the control box placed directly beside the mold, enabling intermittent water supply, fast response, centralized management, and fewer pipelines, which simplifies insulation and minimizes heat loss. With delivery pressure exceeding 10 kg, its transfer efficiency is higher, and heat transfer rate is nearly doubled compared to conventional systems.
On the market expansion side, the company has actively progressed and successively become a supplier for renowned automakers such as Great Wall Motors and Chery Automobile, supporting the production of integrated automotive body structures and building a strong reputation and brand image in the industry.
At the early stage of each project, our professional technicians conduct in-depth evaluations at the customer’s factory. They assess the die casting production process, mold structure, and existing equipment conditions. Based on the results, combined with customer requirements for precision, efficiency, and energy consumption, we tailor the most suitable temperature control equipment solution. From equipment selection and system configuration to installation layout, every step is carefully designed to ensure a system that meets real production needs.
To help customers maximize the effectiveness of their temperature control equipment, we provide comprehensive training and technical support services. Upon delivery, professional engineers conduct on-site training for customer operators, explaining equipment operation methods, daily maintenance essentials, and troubleshooting for common issues, ensuring operators can master the equipment proficiently.
To ensure long-term stable operation of temperature control equipment, we conduct regular follow-up visits and maintenance. Our after-sales team performs scheduled inspections, cleaning, line checks, calibration of temperature sensors, replacement of consumables, and other tasks. This proactive maintenance helps identify and resolve potential issues in time, extending equipment service life and keeping performance at its best. During follow-ups, we also communicate closely with customers to understand equipment usage and new requirements, providing optimization advice and upgrade solutions.
Looking ahead, Xinyu will continue to follow an innovation-driven development philosophy, increase investment in R&D, and continuously improve technical standards and product quality. We are committed to contributing more expertise and solutions to the die casting industry, working hand in hand with our customers toward a brighter future.
