Industry Engagement & Strategic Partnerships
At Longchao, we believe that progress is born from collaboration. We don’t just supply filters; we immerse ourselves in the global foundry ecosystem to stay at the forefront of metallurgical technology.
Global Foundry Collaboration: We actively participate in international trade fairs and technical symposiums (such as MetalChina and GIFA), engaging with leading engineers to exchange insights on the future of molten metal filtration.
Joint R&D Initiatives: We partner with metallurgical research institutes and high-end foundries to develop customized Silicon Carbide (SiC) solutions that address specific casting challenges, such as extreme temperature fluctuations and complex alloy compositions.
The Feedback Loop: Customer-Centric Innovation
Your performance data is our most valuable asset. We have built a robust “Feedback-to-Innovation” loop that ensures our products evolve alongside your manufacturing needs.
Real-Time Performance Monitoring: We encourage our partners to provide detailed performance reports on filter efficiency, flow rates, and inclusion-trapping results. This data is directly integrated into our quality control system.
On-Site Technical Audits: Our expert engineers are available for on-site visits to observe the casting process firsthand, allowing us to troubleshoot issues and fine-tune our material formulations based on real-world feedback.
Rapid Response System: We maintain a dedicated 24/7 technical support channel. Whether it’s a suggestion for a new pore size or a report on thermal shock resistance, every piece of feedback is reviewed by our R&D team within 48 hours.
