KSY Plastic Machinery’s KSY45 / KSY50 / KSY55 / KSY65 small extrusion blow molding machines cover 5ml–3L cosmetic, pharmaceutical, food and daily chemical container production. Built in Dongguan, China — stable, easy to operate and fully customizable.
Four compact blow molding machine models optimized for small container production below 3 litres. Each machine combines a PLC-controlled head, robust clamping unit and adjustable process parameters — providing clean neck finishes and consistent wall thickness for packaging manufacturers.
Each machine uses the same operating philosophy, but has different screw capacity, clamping force and mould space. Use the detailed parameters below to pre-select the model for your bottle design.

Compatible with global factory standards — fast installation, simple operation, low rejection rate.
Programmed timing, temperature and pressure control with password-protected parameters. Suitable for multiple operators.
Servo oil pump systems save 30–40% power; especially recommended for high-cycle cosmetic packaging production.
Separate closed-loop temperature zones on barrel and die head. Stable melt for thin-wall and high-clarity products.
3.8s to 4.8s dry cycle with multi-head option. Increase bottle output without adding floor space.
Four model sizes, one compact machine platform — switch between product types by changing mould set and process recipe.
Ideal for 5ml–500ml bottles: lotion pump, serum dropper, spray bottle, lip gloss and airless container. Works well with PE, PP and PETG grades.
Produces medicine bottles, eye-drop vials, reagent bottles and small disinfectant containers. Stable neck dimension for induction sealing.
Makes jam jars, sauce bottles, edible oil bottles and small drink bottles. Optional FDA-grade material contact components.
KSY can supply dedicated screw designs for the material your containers are made from. More than twelve resin families are commonly processed on this series.
Send KSY your bottle volume, target material and required output — our engineers will confirm the right model and customize the production solution.
