This product is a key component of the proportional valve airflow control for ventilators. It is a high-performance micro shaped projectile independently developed by our company based on customer performance requirements. The experiment proved that after millions of reciprocating switch movements, the plastic deformation of the spring itself does not exceed 0.02mm.

R&D background
As an important medical device, the ventilator plays an important role in medical treatment. The proportional valve is a key component of a ventilator. And this fragment is a key component in the proportional valve, like the heart of the proportional valve. The performance and accuracy of the shrapnel directly affect the performance of the proportional valve. Prior to this, all proportional valves for ventilators were imported from abroad. In order to break the barrier of complete dependence on imports, we collaborated with our customers to develop this product and received market recognition.

Application of patented technology
In order to achieve the dimensional accuracy of the product and the effect of releasing processing stress. The product manufacturing process adopts a patented technology for composite hardware molds (patent number: ZL2022250153.5) and an intelligent stamping and milling machine and system (patent number: ZL201810774806.4).
