Engineer’s note – KSY45
KSY45 vs KSY50 Comparison
Choose the best machine based on bottle size, cavity count and plasticizing capacity.
| Parameter | KSY45 | KSY50 |
|---|---|---|
| Maximum capacity | 1.8 L | 2 L |
| Min. bottle volume | 5 ml | 5 ml |
| Plasticizing capacity (Φ45) | 25 kg/h | 30 kg/h |
| Plasticizing capacity (Φ50) | 32 kg/h | 38 kg/h |
| Clamping force | 30 kN | 30 kN |
| Dry cycle time | 3.8 s | 3.8 s |
| Machine dimensions | 3.5 × 1.8 × 2.2 m | 3.5 × 1.8 × 2.2 m |
| Machine weight | 4.5 t | 4.5 t |
| Best suited for | Small cosmetics, pharma, food bottle under 1.8 L | Daily chemical, pharma bottle up to 2 L |
For bottles below 500 ml, KSY45 is usually the most efficient. For 500 ml–2 L daily chemical or pharma bottles, choose KSY50 to obtain more production headroom. Every KSY45 / KSY50 unit pairs with a matched custom blow mold designed for your bottle.
Common Features & Advantages
Both machines share the same platform, so spare parts, layout and operation remain consistent.
Siemens PLC control
Touch screen HMI with recipe storage and clear parameter setting for each mould.
3.8 s dry cycle
Fast and stable dry cycle time creates a reliable base for calculating bottle output.
Compact footprint
Very small floor area. Suitable for clean cosmetic or pharmaceutical packaging workshops.
Closed-loop temperature
Multiple temperature zones keep the parison at a consistent temperature for stable production.
Energy-efficient drive
Hydraulic or servo drive available depending on customer requirement and local energy policy.
Simple maintenance
Modular layout makes cleaning, screw changes and basic maintenance faster.
Main Applications
Ideal for bottles from 5 ml to 2 L in cosmetic, pharma and daily chemical packaging. These bottles are typically finished with a neck trimming machine and bundled on a bottle packing machine before shipping.
Cosmetic & Personal Care
Lotion bottles, serum containers, spray bottles and small cosmetic pourables.
Pharmaceutical Packaging
Medicine bottles, eye drop containers, nasal spray bottles and reagent packaging.
Food & Household
Small seasoning bottles, honey jars, shampoo and hand wash bottles up to 2 L.
