How to choose a high-quality injection molding machine?

31 Jul.,2025

Choosing a high-quality used injection molding machine requires comprehensive consideration of multiple factors to ensure that the equipment can meet your production needs and has a long service life. Here are some key steps and suggestions to help you choose a high-quality used injection molding machine:

 

1. Clarify production requirements

 

① Product type and size: Determine the type, size and weight of the product you want to produce, which will determine the injection molding machine tonnage and mold size you need.

② Production volume: Estimate your monthly or annual output and choose equipment that can meet production needs.

③ Material type: Understand the type of plastic material you will use (such as PP, ABS, PC, etc.) and ensure that the injection molding machine can handle these materials.

④ Automation requirements: Consider whether automation functions are needed, such as manipulators, automatic feeding systems, etc.

 

2. Choose a reliable supplier

 

① Reputation and experience: Choose a second-hand injection molding machine supplier with good reputation and rich experience, and check customer reviews and cases.

② After-sales service: Ensure that the supplier provides complete after-sales service, such as equipment installation and commissioning, operation training, repair and maintenance, etc.

 

4. Equipment inspection and evaluation

 

① Appearance inspection: Check whether the equipment has obvious damage, rust, deformation, etc.

② Operation inspection: Start the equipment and check whether each component is operating normally, whether there is abnormal noise, vibration, etc.

③ Hydraulic system inspection: Check whether the hydraulic system has oil leakage and whether the pressure is normal.

④ Electrical system inspection: Check whether the electrical system is safe and reliable and whether the line is aging.

 

5. Performance test

 

① Trial run: Conduct a trial run before purchase to check whether the key parameters of the equipment, such as injection speed, pressure, and temperature control, are normal.

② Sample production: If possible, ask the supplier to use the equipment to produce samples to check whether the product quality meets the requirements.
