Syringe Filling Machine

Why is automated syringe filling so important to the process?

Elimination or minimization of air voids is critical to the manufacturing process. When an air pocket passes through the dispense tip it tends to “spit” or result in an incomplete dispense. Either occurrence will lead to a rejected part.  Air pockets will cause a spring-like compression in the fluid forcing an extended stroke length of the linear drive system increasing cycle time.  AirFree® filling reduces cycle time.

When using multiple SmartDispensers® in an automation system it is very important to fill each syringe to the same height. Because of the linear drive systems high repeatability, all four syringes will empty at the same time minimizing changeover time.

The SmartDispenser® will not dispense less than a full deposit on the last dispense of a syringe reservoir assuring the last dispense will not result in a rejected part.  When filling the syringe the fill height can be calculated so each syringe will dispense a full deposit leaving the reservoir completely empty on the last dispense. Contact your Fishman® Sales Representative for calculation information.

No fluid should permeate the front seal of the AirFree® piston. Pouring fluid in the large end of the piston is not only messy but often coats the sides of the syringe with fluid. Inserting the piston with coated walls often results in  a breached front seal. This allows fluid to leak by the piston creating system pressure loss. Pushing on the piston post-filling with a rod or screw driver can cock the piston causing a front seal breach. Always insert the piston to the bottom of the empty syringe and fill the fluid through the nose (small end). Fishman® offers several automated syringe filling systems making the filling process easy, clean and fast.
