Our Manufacturing Capabilities
Why Choose PUNEDA？
Global Manufacturing Capability PUNEDA is a trusted OEM car refrigerator manufacturer serving global automotive brands. With a workforce of over 300 employees, we operate a complete in-house manufacturing system that covers product development, tooling, injection molding, foaming, assembly, quality control, and supply chain coordination. Supported by an annual sales volume of approximately RMB 100 million, our structure is designed to ensure stable production capacity, consistent execution, and reliable long-term delivery for automotive OEM partners.
PUNEDA operates an independent injection molding workshop equipped with more than 10 injection molding machines across multiple tonnage ranges. All major plastic structural components of our car refrigerators are produced in-house, allowing strict control over material selection, dimensional accuracy, and long-term structural durability. This capability ensures consistent product appearance and mechanical strength throughout mass production.
The production facility is equipped with 4 automatic foaming lines, dedicated to refrigerator cabinet insulation. Automated foaming ensures uniform insulation density and thickness for each unit, significantly improving thermal efficiency consistency compared to manual processes. This capability is critical for maintaining stable cooling performance in both compressor and thermoelectric refrigerators, especially under vehicle vibration and temperature fluctuation conditions.
PUNEDA operates 3 dedicated assembly lines for thermoelectric and compressor car refrigerators, designed to meet high performance and reliability requirements. Each assembly line follows standardized automotive-oriented procedures, covering compressor installation, refrigerant piping, electrical system integration, and functional testing. The production lines support cooling ranges from -22°C to +10°C and are optimized for 12V and 24V vehicle power systems, serving OEM programs and international markets.
Assembly Line for Mini Fridges For thermoelectric and compact refrigerator products, PUNEDA operates 2 high-efficiency mini fridge assembly lines. These lines are designed for flexible production, allowing fast model switching and support for multiple configurations, private labeling, and customized requirements. They are widely used for retail channels, promotional projects, and light OEM cooperation.
Aging Test Room All PUNEDA refrigerators undergo aging and functional testing in a dedicated aging test room before shipment. Products are powered on for 24 to 48 hours to verify cooling performance, electrical stability, and overall operational reliability. This process helps identify early-stage risks and significantly reduces failure rates after market release. Aging testing is a mandatory internal quality control step and a key part of PUNEDA’s quality assurance system.
With over 20 years of experience in industrial product design and visual engineering, Ethan Cole ensures that every PUNEDA fridge is built with the highest standards of structure, usability, and manufacturing detail. From injection molding to automatic foaming, assembly lines and aging tests, his team works closely with the factory to turn concepts into reliable consumer-ready products
