KSY small extrusion blow molding machines produce medicine bottles, eye-drop vials and reagent containers from 5 ml to 2 L in HDPE, PP and LDPE, with stable neck dimensions and repeatable bottle weight.
Small-volume pharmaceutical packaging depends on consistent dimensions, because closures, droppers and induction seals leave little tolerance.
Most pharmaceutical bottles are small, so output is raised with multi-cavity tooling.

See processing notes in the blow molding materials guide.
Neck trimming gives the flat sealing surface that induction seals need. Leak testing is used for bottles large enough to run stably on a conveyor.
Removes neck flash and the dome left by blow-pin calibration on round bottles, leaving a flat, clean sealing surface.
Neck trimmers →Pressure-decay testing catches pinholes and weak pinch-off welds before bottles are packed. Best suited to bottles that travel stably on a conveyor.
Leak testers →Custom molds in tool steel with optimized cooling channels, matched to your bottle drawing and the machine platen.
Blow molds →HDPE and PP medicine bottles are made on small extrusion blow molding machines. KSY45 and KSY50 produce containers from 5 ml to 2 L and can run multi-cavity molds for small bottles.
HDPE is used for most tablet and capsule bottles, PP for hot-fill or sterilizable bottles, and LDPE for squeezable dropper vials. Barrier bottles add an EVOH or PA layer by co-extrusion.
The neck is calibrated by the blow pin during molding, then a neck trimming machine removes the remaining flash to leave a flat sealing surface for caps and induction seals.
Send KSY your bottle drawing, resin grade and annual volume. We will recommend the machine model and cavity count.
