Engineer’s Notes – KSY75-6L

6L container selection: Use HDPE with a wall thickness of 2.8–3.2mm for most lubricant / industrial bottles. If the fluid is sensitive to oxygen, choose a 3-layer PE/EVOH/PE structure.

Liquid level line: This is normally formed directly by the mould. If you want this feature, send us a sample or drawing so we can design the steel mould accordingly.

Multi-layer output: The exact 2- or 3-layer output depends on the extruder configuration. Contact KSY technical sales for a production proposal based on your bottle weight and target hourly output.

Industrial Features & Advantages

KSY75-6L is designed for continuous, reliable production of large household and industrial containers.

New Multi-layer production

2-3 layer co-extrusion creates chemical-resistant inner layers, EVOH barrier layers and strong outer layers for shelf-life extension.

Thick wall capacity

65 kN clamping force and precise parison control are matched to containers from 1.5mm up to 4.0mm wall thickness.

5.2s dry cycle time

A stable dry cycle of 5.2 seconds with 80-95 kg/h plasticizing output supports high output on large single-cavity or multi-cavity tools.

Accurate temperature control

Closed-loop multi-zone temperature control keeps parison temperature stable, especially for higher-melt materials and long vertical parisons.

Energy-optimized drive

Servo-driven hydraulic system reduces heat generation and power consumption during the idle portion of each cycle.

Safety and stability

Siemens S7-1200 PLC, safety door interlocks and alarm notifications provide reliable protection for operators.

6L Container Applications

Typical use for KSY75-6L in industrial packaging.

6L engine oil bottle production with KSY75-6L

Lubricant & Oil Bottles

Engine oil, gear oil, hydraulic oil and agriculture fluid containers with liquid level line options.

Industrial Chemical Containers

Thick-wall HDPE containers for detergents, industrial cleaners, solvent and chemical concentrate packaging.

Household & Cleaning

Large liquid soap, fabric softener, laundry detergent and household chemical containers from 4L to 6L.

Compatible Materials

The machine is compatible with standard blow molding grades and can be configured for special multi-layer structures.

LDPELow-density PE

PPPolypropylene

EVOHBarrier layer

PAPolyamide / Nylon

PETGPET glycol

TPEThermoplastic elastomer

TPUThermoplastic polyurethane

Material recommendation: HDPE is the primary material for 6L oil and chemical containers because of its chemical resistance, stiffness and impact strength. For better ESCR, choose a suitable HDPE blow molding grade based on your filling temperature.

Multi-layer option: If you require EVOH barrier performance, KSY can add the second or third extruder needed for a PE/EVOH/PE structure. Tell us the oxygen / solvent sensitivity of your product and KSY will advise the correct layer combination.

Frequently Asked Questions

Can this machine produce containers with liquid level lines?

Yes. Liquid level lines can be formed directly on the container by the mould design. This avoids a secondary printing or hot-stamping operation and gives clear volume indication for oil and chemical containers.

What is the maximum wall thickness for 6L containers?

The machine is capable of producing containers with wall thickness between 1.5mm and 4.0mm, depending on material, parison programming and mould design. For most 6L HDPE industrial containers, KSY recommends 2.8-3.2mm.

Can this machine produce multi-layer containers?

Yes. KSY75-6L can be configured for 2-3 layer co-extrusion, for example PE/EVOH/PE. Multi-layer construction is often requested for lubricant bottles, agrochemical packaging and food containers where barrier performance is important.

What is a typical production rate for 6L bottles?

In normal single-cavity operation, a 6L bottle of 180–220g can reach roughly 140–180 pieces/hour depending on cooling time, material and wall thickness. Multi-cavity moulds or smaller containers can increase the output.

What after-sales support do you provide?

KSY provides installation supervision, operator training, documentation and remote video support. Spare parts are available from the Dongguan factory. We also offer mold design assistance for liquid level line and multi-layer work.
