Medical one way valve is also called M2000 silicone valve, made of medical grade liquid silicone material. There are two commonly used grades: ISO 10993 and biocompatibility report, which can be used for ELISA KIT.
The influence of different slit cut of medical one way valve on pressure and flow rate is: the larger the opening, the faster the flow rate and the lower the pressure; the smaller the opening, the slower the flow rate and the greater the pressure.
1) Leak-proof and slit dispensing angle test: For a qualified cross slit silicone valve, there will be no drip after the 24H*7 Days Inverted Leak-proof Test, and the slit dispensing angle must be controlled within ±15 degrees.
2) Air leakage test: After vacuuming for 24H*7 Days, there is no air leakage.
The inspection method of medical one way valve is our company's precise high-end technology. First, the front-end process "automatic punching" has screened out defective products, such as missed punching and continuous wire, and then use AOI automatic testing equipment to test the quality, appearance, size, opening of medical one way valve. Machine automatic inspection with fast efficiency, high precision, and the possibility of greatly reducing product pollution by machine operation.
1. The size of medical one way valve is too large, and the concentration of the flowing medium is small.
2. The overall hardness of medical one way valve is low.
3. The slit cut of medical one way valve has gaps.
4. The wall thickness of the medical one way valve is uneven.
Step 1: Compression Molding
Step 2: Automatic Punching Of Medical Check Valves
Step 3: AOI Quality Inspection
Step 4: Manual Inspection
Step 5: Dust Free
Step 6: Packing And Delivery
