What is a venous piston three-way valve?

The three joints of the three-way valve are respectively communicated with the needle seat of the blood transfusion device, the needle seat of the blood anticoagulation device and the venipuncture and cannula through the medical rubber hose.


At Yize Mould, we have medical plastic injection mold device equipment for our customers. This project highlights our breakthrough in medical plastic injection mold devices while guaranteeing close tolerance injection molding, which equates to cost savings over the entire product life cycle.

Thickness Analysis

The product wall thickness refers to the glue level of the part. How to use UG to analyze the product wall thickness? After getting a model, before preparing to medical plastic injection mold device design, it is necessary to analyze the wall thickness first to see if the wall thickness is uniform, find its uneven position, so as to make adjustments, so as to avoid the product being caused by the wall thickness in the life of the product. defective products

Medical plastic injection mold device Filling Analyses

Fill analysis predicts the flow of thermoplastic polymers within the mold during the filling phase. The analysis calculates the flow front incrementally past the part from the injection location. Flow continues until the speed pressure switch point

Welding line position 

This joint is not as strong as uninterrupted flow. Since the flow fronts can merge together and continue to flow through the cavity, there is a greater chance of compressing this area, thereby increasing its strength.
