Comprehensive Importance of Filtration in Injection Molding Machines

Injection molding machines rely on precise hydraulic systems to achieve high-quality and consistent results. Effective filtration plays a critical role in maintaining optimal performance by removing contaminants from both the hydraulic fluid and the air that enters the hydraulic tank. In this article, we will explore the comprehensive importance of filtration in injection molding machines, encompassing the filtration of hydraulic fluid and air. We will discuss how filtration contributes to system reliability, component longevity, energy efficiency, product quality, and reduced maintenance costs.

1.???Contaminant Removal for Clean Hydraulic Fluid: Filtration systems designed for hydraulic fluid are essential for removing contaminants such as particles, water, and dissolved gases. These contaminants can cause abrasive wear, valve blockages, and component damage if left unfiltered. Clean hydraulic fluid ensures optimal lubrication, prevents system overheating, and protects seals and sensitive components. By maintaining clean hydraulic fluid, filtration contributes to extended component life, reduced maintenance costs, and enhanced machine reliability.

2.???Filtration of Air for the Hydraulic Tank: In addition to filtering hydraulic fluid, attention must be given to the air that enters the hydraulic tank. Airborne contaminants, including dust, dirt, and microorganisms, can contaminate the hydraulic fluid when drawn into the tank. Air filtration systems, such as intake filters and breathers, are crucial for removing these contaminants. By ensuring clean air supply, filtration reduces the risk of contamination and subsequent damage to the hydraulic system. It also helps maintain a controlled environment within the tank, preventing moisture condensation and fluid degradation.

3.???Improved Energy Efficiency: Clean hydraulic fluid and filtered air contribute to improved energy efficiency in injection molding machines. Contaminants in the hydraulic fluid increase viscosity, resulting in higher energy consumption and reduced system efficiency. Similarly, airborne contaminants in the hydraulic tank cause increased friction and resistance, leading to additional energy expenditure. Effective filtration minimizes these energy losses, optimizing machine performance, and reducing operating costs.

4.???Consistent Product Quality and Process Stability: Filtration of both hydraulic fluid and air is crucial for achieving consistent product quality. Contaminated hydraulic fluid or air can introduce inconsistencies in the molding process, leading to product defects, dimensional variations, and compromised surface finishes. By implementing robust filtration systems, injection molding companies ensure a clean and controlled environment within the hydraulic circuit. Consistent product quality is vital for customer satisfaction, meeting industry standards, and preserving brand reputation. Filtration also contributes to process stability, reducing scrap rates and enhancing manufacturing efficiency.

5.???Reduced Downtime and Maintenance Costs: Neglecting filtration can result in increased downtime and maintenance costs. Contaminants in the hydraulic fluid or air can cause clogged valves, malfunctioning components, and system failures. Regular maintenance, repairs, and unplanned downtime incur expenses and disrupt production schedules. Prioritizing filtration minimizes the risk of system failures, extends the lifespan of hydraulic components, and reduces maintenance and repair frequency.

Filtration is of paramount importance in injection molding machines, encompassing both hydraulic fluid and air filtration. By removing contaminants, filtration ensures clean hydraulic fluid, controlled tank environment, system reliability, extended component life, and reduced maintenance costs. It contributes to improved energy efficiency, consistent product quality, and process stability. By implementing effective filtration systems and adhering to regular maintenance practices, injection molding companies optimize machine performance, minimize downtime, and deliver high-quality products that meet customer expectations. Prioritizing comprehensive filtration ensures a clean, efficient, and reliable hydraulic system, paving the way for sustained success in the competitive injection molding industry.

On our machines we always use high end-filtration systems for both hydraulic oil and air intake. Oil goes through three seperate filters as fine as 10 microns to ensure the maximum stability and lifetime for Hürmak machines. We are proud to use top notch filtration systems produced by MtMesa Hydraulic in Turkey, just like our machines. Please feel free to get in touch for any questions or inquiries.
