Injection molding machines are the core equipents in the plastic manufacturing industury that directly affects production's efficiency and quality, enterprise's profitability.So, injection molding machines that have a long time to use is very important.There are many factors can affect the service life of injection molding machines.
1.Machines'type and quality
Different types of injection molding machines have distinct structural designs and component durability, leading to varying service lifes:
Hydraulic Injection Molding Machines: Rely on hydraulic systems for clamping and injection. Long-term high-pressure operation causes wear to hydraulic components, resulting in an average lifespan of 8 to 12 years. High-quality models from reputable brands can extend to 15 years with proper oil replacement and leak repairs.
Electric Injection Molding Machines: Driven by servo motors with fewer moving parts and lower mechanical wear, they have a longer average lifespan of 12 to 18 years.
Hybrid Injection Molding Machines: Combine hydraulic clamping and electric injection, with a lifespan between 10 to 15 years. Their service lifes depend on the hydraulic system's degree of wear and the stability of the electrical units.
Besides,the core compents' quality is very critical.Machines using high-temperature-resistant alloy steel for screws and barrels are 30% more durable than those with ordinary steel, as they resist wear from molten plastic.
ARBUEO is designed and manufatured according to 15 years service life standard.For seals,ARBUEO uses low-resistance steel rings,because they are made of metal,will not age.All joint screws use G-threads with O-rings without winding raw material belts.There will be no oil seepage.
2.Maintenance Practices
Routine Cleaning: Neglecting to clean plastic residues in heating barrels and screws leads to carbonization and surface scratches, shortening component life by 2 to 3 years. Weekly cleaning is recommended.
Lubrication Management: Moving parts require lubrication every 200 operating hours. Inadequate lubrication causes metal-to-metal friction-unlubricated guide rails may need replacement in 1-2 years, while properly lubricated ones last 5-8 years.
Timely Replacement Of The Easily Damaged Parts: Seals, O-rings, and filters must be replaced periodically. A leaking hydraulic seal, if not be solved in time that will causes contaminates oil and damages pumps, reducing machine life by 1-2 years.
3.Operating Conditions
Usage intensity and environment significantly impact lifespan:
Production Intensity: Continuous 24 hours operation increases load, shortening lifespan by 10%-20% compared to 8-12 hour use. A hydraulic machine running continuously may last 8-10 years, while intermittent use extends it to 12-15 years.
Process Parameters: Long-term use of excessive temperature (over 50°C above plastic melting point) or pressure (over 10% of rated clamping force) causes barrel overheating and locking mechanism deformation, reducing life by 2-4 years.
Environmental Factors: Dust, high humidity (over 80%), and temperature fluctuations damage electrical systems and mechanical parts. High humidity will cause the guide rails to rust and the control panel to short-circut, shortening lifespan.
All in all,Injection molding machines are vital to manufacturing, with their service life and performance directly impacting enterprise profitability. By understanding lifespan-influencing factors and adopting proactive maintenance, enterprises can extend machine life, reduce costs, and stay competitive in the global market.
