Things Manufacturers Should Consider Before Buying a PET Injection Moulding Machine


Buying a PET injection moulding machine is one of the major decisions for any manufacturing enterprise. A suitable machine will provide improved quality of the product, reduce waste, and save on production costs. With the demand for PET preforms continuing to grow in packaging and beverages, besides price, manufacturers need to evaluate long-term performance and reliability.


Understand Your Production Needs


Before choosing a injection moulding machine, it is important to be clear about your needs. Consider:

Type of PET products that you will produce, mainly preforms

A projection of your daily/monthly production output

Number of cavities in the mould

the required cycle time

A machine should fulfil current needs and allow for future expansion.


Machine Stability and Performance


PET processing requires consistent control over long production runs. An unstable machine will lead to quality problems and increased rejection rates. 


Look for:

Smooth and stable operation of machines

Constant injection and holding pressures

Robust and reliable clamping performance

Sound stability will assure uniform performance quality, with reduced downtime.


Energy Consumption and Operating Costs


Energy cost is a major component of PET preform manufacturing. An energy-efficient machine helps to control the operating expense over time. 


Some key factors to think about include:

Improved energy consumption

Efficient systems for heating and cooling

Lower power consumption per cycle

Improved energy efficiency enhances overall cost per preform.


Automation and Ease of Operation


Automation improves consistency and reduces dependency on manual processes. Companies should consider the following:

Compatibility with automation and robots

Easy integration of auxiliary equipment

Easy-to-use controls on machines

Automation-ready injection moulding machines allow for production scalability.


Mould Compatibility and Flexibility


The machine shall work smoothly for mould sizes and different configurations. Important factors include:

Support for high-cavity moulds

Flexibility for future mould changes

Precise mould alignment

This flexibility protects your investment in the long run.


Service Support and Reliability


Even the best PET injection moulding machine require regular service and support

Consider, before purchase: 

Availability of service engineers 

Spare parts support

Training and technical assistance 

Service response time 

Robust after-sales support contributes to continuity in production.
