What is the difference between KSY55 and KSY65?

KSY55 is designed for containers up to 2.5L and has a plasticizing capacity of 40-48 kg/h. KSY65 is designed for containers up to 3L, with a plasticizing capacity of 50-60 kg/h and a higher clamping force of 45kN.

Which machine is better for HDPE bottle blowing?

Both models can process HDPE reliably. For HDPE bottles up to 2.5L, KSY55 is usually the most cost-efficient. For 3L bottles or products requiring thicker walls, KSY65 provides higher plasticizing capacity and clamping force.

What is the dry cycle time of these machines?

KSY55 has a dry cycle time of 4.2 seconds and KSY65 has a dry cycle time of 4.5 seconds. Actual bottle output depends on mould cooling, cavity count and container wall thickness.

Engineer’s Notes – KSY55

Practical recommendation: KSY55 is the first choice for 2.5L HDPE food bottles and chemical containers with moderate wall thickness. The Φ60 mm screw option provides about 20% more plasticizing power while keeping the same compact footprint.

Dry cycle time: 4.2s means stable cycle time for single-cavity or multi-cavity moulds. Final output depends on bottle weight and mould cooling efficiency.

Selection guideline for medium size bottle production line:
For 3L bottles with a required wall thickness over 2 mm, or when using a multi-cavity mould with higher combined shot weight, choose KSY65. For usual 1L–2.5L HDPE containers, KSY55 delivers the best overall efficiency.

Common Features & Advantages

Both machines use the same KSY platform, making maintenance and configuration planning easier.

Servo oil pump

Automatic servo pump adjusts oil flow by real demand, reducing power consumption compared with fixed pumps.

Siemens S7-1200 PLC

Reliable control for time, temperature and pressure. Touch-screen HMI makes parameter setting simple.

Dry cycle time

KSY55: 4.2s / KSY65: 4.5s. A stable dry cycle is the foundation for predictable output.

Multi-cavity capable

Both machines can be configured with single or multi-head tooling for higher production flexibility.

Energy saving design

22–28 kW/h average power consumption keeps production costs low for continuous bottle lines.

Container quality

Rigid clamping plate and synchronous mould movement improve neck finish and dimensional consistency.

Main Applications

These machines are widely used in the food, chemical and household industry for medium-size bottles.

Frequently Asked Questions

What is the price range for a 3L blow molding machine?

KSY65-J3L machine pricing depends on screw size, number of die heads, control options and other customized features. Please contact KSY with your bottle drawing and production target to receive an exact quotation.

Which model is better for HDPE bottle blowing?

Both KSY55 and KSY65 can process HDPE reliably. For HDPE bottles up to 2.5L, the KSY55 is usually more efficient. For 3L bottles with thicker walls or higher output, choose KSY65 with its higher plasticizing capacity and clamping force.

What production output can I expect for 2.5L containers?

With KSY55, production output for a standard 2.5L HDPE container is approximately 180–220 pieces per hour in continuous operation. Multi-cavity moulds can increase this output. Actual results depend on material, wall thickness and cooling.

Is this suitable for a medium size bottle production line?

Yes. Both models are designed for medium-size bottle production. They can be integrated with leak testers, labeling machines and conveyors to form a complete 2.5L–3L bottle production line.

What is the dry cycle time of KSY55 and KSY65?

KSY55 has a dry cycle time of 4.2 seconds. KSY65 has a dry cycle time of 4.5 seconds. The actual production cycle depends on mould cooling, container weight and cavity number.
