Self‑sealing Magnetic Filter Screen for Haitian Injection Molding Machine
Product Overview
This self‑sealing magnetic filter screen is an essential protective component of the hydraulic system for Haitian injection molding Machine. It is installed inside the hydraulic oil tank or oil circuit to adsorb and intercept iron‑impurity particles mixed in hydraulic oil. The self‑sealing structure enables quick installation and replacement without completely draining hydraulic oil, greatly simplifying maintenance work. Equipped with strong‑magnetic material and high‑precision filter mesh, it can effectively remove metal wear debris produced by long‑time operation of hydraulic pumps, valves and cylinders, reduce component abrasion, and keep the whole hydraulic system clean. Regular replacement of this filter screen can prevent hydraulic valve blockage, oil pollution‑related failures and extend the service life of core hydraulic parts of the injection molding Machine.

Working Principle
While the hydraulic oil circulates inside the hydraulic system, iron‑based metal particles generated by friction of pump, motor and valve flow through this filter screen. The built‑in magnet firmly adsorbs ferromagnetic impurities, and the fine mesh blocks non‑magnetic solid contaminants. Its unique self‑sealing design automatically closes the oil passage when the filter element is pulled out, preventing hydraulic oil leakage. If the filter screen is blocked or magnetism weakens, oil pollution will accelerate wear of hydraulic components, resulting in unstable pressure, slow action or abnormal noise of the injection molding Machine. Timely replacement ensures clean oil circulation and stable operation of the hydraulic system.
Core Advantages
1. Self‑sealing quick‑change structure, no need to drain hydraulic oil during replacement, saves maintenance time of the injection molding Machine.
2. Dual‑filtering effect of magnet and stainless‑steel mesh, efficiently removes metal wear debris and solid particles, protecting the whole hydraulic system.
3. High‑quality permanent magnet with long‑lasting magnetic force, not easy to demagnetize under high‑temperature hydraulic‑oil environment.
4. Standard dimensions, good interchangeability, directly replace the original filter screen for Haitian injection molding equipment.
5. Reduce failures caused by oil contamination, lower maintenance costs and improve the stability of injection‑molding production.
Application Range
This self‑sealing magnetic filter screen is specially used for the hydraulic system of Haitian series injection molding Machine. Widely used for daily maintenance, overhaul and spare‑parts replacement in plastic‑injection factories, equipment repair workshops and hydraulic‑system service stations.
