• Mold size: The mold size of the injection machine can be measured in length and width. It will determine the shape and size of the preform produced.
• Power: The driving motors of the injection machines operate using different power requirements. It is measured in kilowatts (kW) and ranges from 5.5 to 50 kW. The power will determine the energy it uses for injection and heating.
• Machine Dimensions: The overall length breadth and height of the injection machine will determine the space needed for installation and the weight capacity in the industrial floor.
• Material compatibility: The automatic injection machine is compatible with different materials such as PET, PP, and PVC.

Maintenance

Users have to take care of the proper maintenance to keep their injection molding machines in top working conditions. Regular maintenance will ensure better preform quality, reduce downtime, and improve production efficiency.

Operators can follow the manual provided by the manufacturer to schedule preventive maintenance. The instructions in the manual will include lubrication schedules, replacement parts, and specific maintenance routines. Or, they can consult with the maintenance professionals or technicians who are familiar with the machine.

Here are a few general maintenance tips applicable to most automatic preform injection machines:

• Regular Lubrication:Lubricate the moving parts and components of the maintenance machine as per the manufacturer's instructions. Regular lubrication is important to reduce friction and prevent premature wear and tear of components.
• Routine Cleaning:It is crucial to regularly clean the injection machine and remove any dirt or debris buildup. Routine cleaning prevents material clogs and ensures optimal performance.
• Cooling System Maintenance:Operators should routinely check and clean cooling channels in molds. They can flush out any obstructions using water or air to maintain optimal cooling efficiency. Users should also monitor the temperature of the molds and adjust the settings accordingly.
• Operator Training:It is important to train operators on the proper use and maintenance of the injection molding machine. Ideally, the operator should be well-versed with the machine's features and functions. It will prevent unnecessary damage caused by improper handling.

How to choose automatic pet preform injection machines

When purchasing an automatic PET preform injection machine, buyers must thoroughly understand their requirements before finalizing a choice. From the production capacity to the level of automation and other specifications, they need to study various features related to the injection machine.

The first step is to comprehend the production capacity or the number of preforms produced per hour. Once the required capacity is determined, it is easy for buyers to shortlist machines with specific capabilities. The next crucial aspect is to evaluate the level of automation in a machine, such as the control system and other automated features, for instance, whether it has a fully automated PLC control or requires manual intervention.

Another feature to consider is the compatibility and flexibility of the machine with different types and sizes of PET preform molds. Additionally, to avoid operational costs, buyers must also check the energy efficiency of the injection machine and its overall consumption requirements. Evaluate the space requirement to ensure that the dimensions perfectly fit into the intended industrial space. The noise level of the machine is another aspect to consider since high noise levels may require additional soundproofing or noise control.

Since preform injection machines work with high temperature and pressure, the build quality must be sturdy enough to ensure long-lasting performance. If buyers want to invest in a single machine for multiple tasks, they should get a multi-functional automatic injection machine preform. Finally, once the model is shortlisted, checking after-sales services and spare parts availability is crucial before concluding the purchase.
