The global manufacturing sector is undergoing a rapid shift toward micro-scale production. When smartphone camera modules demand 0.1mm sealing precision and minimally invasive medical instruments require nano-level density control of cushioning materials, traditional polyurethane foaming systems struggle with excessive output and insufficient precision. Feilong Polyurethane Equipment has launched a Precision Micro Foaming Test Machine that redefines production standards for small, high-precision components with groundbreaking micro-scale engineering capabilities.
Conventional polyurethane foaming systems offer flow control accuracy of only ±5%. While acceptable for large automotive parts such as bumpers, this level of error becomes catastrophic when dealing with micro seals requiring as little as 0.01g of raw material—where a slight deviation can cause product failure. Feilong’s system achieves microflow stability at ±0.5%, equivalent to controlling just 0.005 ml of deviation in a 1 ml injector. This capability has been certified by the National Quality Supervision and Inspection Center for Plastic Machinery.
The system also features advanced dynamic mixing technology with dual-screw asynchronous agitation and real-time pressure feedback 10 times per second. This enables precise molecular-level mixing of A/B components within 0.5 seconds—a performance previously considered unattainable in micro polyurethane applications.
1. Micro Seals for New Energy Batteries
This system is being used to enhance sealing performance in EV battery packs. Laboratory tests from a leading battery manufacturer show that O-rings produced with this system achieve a compression set of only 8% after thermal cycling between –40°C and 125°C, outperforming the industry average of 15%. This boosts battery sealing from IP67 to IP68, supporting the rise of 800V high-voltage platforms.
2. Electronic Component Encapsulation
In high-frequency 5G modules, precision is critical. The system integrates a CCD vision unit with a six-axis robotic arm, injecting polyurethane material with 0.1 mm positional accuracy into micro cavities as small as 0.5 mm × 0.3 mm. This enables stable high-frequency sealing in millimeter-wave filters and RF components.
3. Medical-Grade Micro Cushioning Components
Feilong’s Gradient Density Foaming Technology enables customizable hardness transition—from Shore A30 to A80—within a 2 mm cushioning layer. In animal trials conducted by a Shanghai-based medical device company, laparoscopic instruments equipped with these cushions demonstrated 40% improvement in operating precision and 62% reduction in tissue trauma.
Traditionally, developing a micro polyurethane formula required over 200 trial iterations and 3–6 months of validation. Thanks to Feilong’s 100-group parameter memory and cloud-based formula database, the development cycle is now reduced to just 45 days.
As manufacturing enters the era of millimeter-scale innovation, Feilong’s Precision Micro Foaming Test Machine is more than a piece of equipment—it is a strategic driver of micro-manufacturing evolution. From semiconductor packaging to microrobotics and wearable medical devices, Feilong is empowering new industries through micro-level precision.
