Front Filling
Product enters from the nozzle end before the remaining package components are assembled.
KINGPACK engineers the filling route, syringe handling, plunger insertion and inspection around your formulation and package—not around one fixed machine.
Multi-head front filling line · machine referenceThe correct direction follows the syringe structure, component supply state and product behavior.

Product enters from the nozzle end before the remaining package components are assembled.

Product enters through the open barrel tail, followed by controlled venting and plunger insertion.
The KPZSQ-2 illustrates a rear-filling platform for high-viscosity paste. It is a machine reference—not the definition of the complete veterinary syringe range.

Only the modules required by the formulation, syringe and quality criteria are integrated.
Viscosity, temperature, settling, foam and stringing determine the contact path.
Tip, barrel, plunger and closure determine orientation and assembly.
Samples and acceptance criteria determine what is tested and recorded.
Sample test referenceProfessionalism is shown through documented trials with the actual product and package.
This determines the dosing principle, hopper, transfer method, nozzle and whether heating or agitation should be evaluated.
The route depends on how the barrel, tip closure, piston and plunger are supplied and assembled. We confirm it from samples.
Please provide the complete syringe set, drawings, tolerances, bulk packing and the supply state of each component.
Formulation behavior, target dose, package tolerances, feeding stability and the agreed quality criteria.
Share your formulation, syringe samples and production target. Our engineering team will recommend a practical filling route and sample-test plan.
Contact Our Engineering TeamWe start with how the material behaves, then configure the contact path, dosing and assembly modules.
