Edible oil

PLT268PET injection molding machine — representative series view

Representative machine and component views. Configuration varies by model.

Machine range: 5 PET models
Clamping force: 2,180–5,000 kN
PET screw design: 25:1 L/D ratio

PET preform applications

It starts with
the right preform.

From drinking water to edible oil, the preform design defines the mould, injection capacity and machine configuration.

Clear and coloured PET preforms in a range of neck finishes and lengths — PET preform examples · final dimensions follow your bottle design

01
Water bottles
Transparent PET preforms for drinking-water bottles.
02
Carbonated beverages
PET preforms selected around the bottle and neck-finish design.
03
Edible oil & larger formats
Longer preforms supported by the extended ejector stroke; mould and machine selection depend on the preform geometry.

Inside the system

Designed around
the PET cycle.

Dedicated plasticizing, controlled injection and dependable mould handling work together through each production cycle.

01 / ENGINEERING

Clamping built around the mould

A rigid clamping structure with generous opening stroke and mould space accommodates different preform mould sizes. Extended ejector travel and dedicated ejector force support the release of longer preforms.

02 / ENGINEERING

A screw designed for PET

Dedicated PET screw and barrel design with a 25:1 L/D ratio. Special materials and heat treatment support plasticizing, colour mixing and preform transparency.

03 / ENGINEERING

Balanced twin-cylinder injection

A twin-cylinder arrangement balances the injection drive. The oil circuit is designed to reduce return resistance and support stable high-pressure injection.

04 / ENGINEERING

Guided, aligned movement

An integrated injection-unit carriage and linear guides keep movement aligned, reduce friction and support responsive injection control.

05 / ENGINEERING

Hydraulics & lubrication

Fixed-point, metered lubrication supports reliable operation. A fast-closing hydraulic circuit and a reinforced hydraulic motor support clamping and plasticizing.

06 / ENGINEERING

Control of the preform cycle

Adjustable mould needle-valve timing, screw speed and proportional back pressure. Mechanical, electrical and hydraulic protection work together, with interfaces for robotic handling and conveyors.

PET preform moulds

Match the mould
to the preform.

Choose cavity count and neck finish around preform weight, geometry and target output. Compatibility is checked against the selected machine.

16-cavity PET preform mould — 16Cavity preform mould

32-cavity PET preform mould — 32Cavity preform mould

48-cavity PET preform mould — 48Cavity preform mould

72-cavity PET preform mould — 72Cavity preform mould

Additional mould format

Wide-mouth preforms.

A dedicated mould option for wide-mouth PET preforms. Share the neck finish, preform drawing and weight so the mould and injection unit can be matched together.

Optional configurations

Configure for
your production.

Options are selected to suit the preform, mould and operating conditions. They are not included in every standard configuration.

Discuss the options

01
Enclosure & dehumidification
A fully enclosed clamping area and mould dehumidifier help manage condensation during chilled-water cooling.
02
Integrated cooling connections
A central cooling-water interface keeps mould connections organised.
03
Preform ejection detection
Photoelectric detection checks that preforms have been released before the next closing cycle.
04
Colour dosing
An optional colour-mixing feeder connects to the reserved installation point.
05
Infrared heating
Infrared barrel heating bands are available as an optional configuration.
06
Higher-power servo drive
An increased servo-motor specification can be selected for the production requirement.
07
Overlapping cycle movements
Electric plasticizing or a dual-hydraulic synchronisation system allows plasticizing to overlap with mould opening and ejection.
