Invention Patent | A High-Pressure Clamping Device for Vertical Injection Molding Machines, Supporting Innovation and Upgrading of Fuen Injection Molding Systems

As an important indicator of a company’s innovation capacity and a driving force behind its sustainable development, Funeng Precision has consistently upheld a craftsman’s spirit in research and innovation, relentlessly honing its expertise. The company now holds more than 30 patents, and on August 25, 2023, it was once again awarded an invention patent certificate by the National Intellectual Property Administration for its “High-Pressure Mold‑Clamping Device for Direct‑Press Machines,” thereby ensuring the sustainable application of Funeng’s injection‑molding systems and helping customers achieve cost reduction and efficiency gains.

As the injection molding machine market continues to evolve, direct‑pressure injection molding machines have gained widespread favor. Their distinctive linear guide‑rail clamping structure enhances operational efficiency, reduces wear on structural components, and extends equipment lifespan. However, in existing direct‑pressure injection molding machines, when subjected to frequent high‑intensity operation, relying solely on wear‑resistant rings to support the high‑pressure clamping mechanism can easily lead to oil leakage or component wear, resulting in substantial maintenance costs. Moreover, such issues often necessitate shutting down the machine for complete disassembly and repair of the clamping system, which in turn causes economic losses and may delay product delivery.

Founeng Precision’s patented “High-Pressure Clamping Device for Vertical Presses” optimizes the clamping guide‑positioning support structure and incorporates a combined technology featuring guide rods and seals, thereby addressing numerous issues commonly encountered in vertical presses and delivering long-term benefits to customers.

► Addresses issues such as oil leakage and wear of structural components during equipment operation, ensuring smooth performance under high-frequency, high-pressure conditions and enhancing production efficiency.

► Equipment maintenance and repair are more convenient, supporting partial disassembly for servicing without requiring full‑machine dismantling. This approach enables frequent maintenance in a streamlined and efficient manner, extending the service life of critical clamping units and allowing for long‑term continuous operation.

► Directly enhances the cost-effectiveness of direct‑pressure injection molding machines. While the critical structural components of conventional direct‑pressure machines typically require maintenance and replacement every three years, the patented technology extends this interval to six years. Moreover, the replacement cost for these patented components is only one-third that of standard machines, significantly reducing customers’ long-term maintenance expenses.

Funneng Precision Engineering Group has consistently upheld the principles that technology is the primary productive force, talent is the primary resource, and innovation is the primary driving force. Guided by a product development strategy of “producing one generation, developing one generation, researching and developing one generation, and reserving one generation,” the Group is advancing its injection molding systems to be more stable, more efficient, more energy‑saving, and smarter.
