Electric Discharge Die Head Screen Changer – Labor-Saving and Durable Core Component for Granulation Discharge Filtration
The Electric Discharge Die Head Screen Changer is a dedicated supporting device for plastic granulation discharge, designed for impurity filtration and wire-drawing processes of granulation machines and auxiliary equipment. It ensures stable adaptation to discharge requirements and can be used in small and medium-sized batch production or large continuous production lines. By maintaining high discharge purity and consistent molding quality, it is a core, preferred accessory for granulation equipment.

Precision Engineering with Dual Stations
Constructed from 45# steel and treated with 120 kW high-frequency quenching, this screen changer is precision-machined and assembled for durability and long-term stability. The screen plate is highly precise, with a hardness of 50–55 HRC. For example, the 200×200 specification has 6×506 holes, providing a large filtration area. The dual-station design extends service life, increases the screen change interval, reduces downtime, and saves labor costs.
High Cost-Effectiveness and Easy Maintenance
Featuring standardized components, easy maintenance, and excellent craftsmanship, the Electric Discharge Die Head Screen Changer ensures stable operation and meets international trade requirements. Its precise discharge adaptation, labor-saving design, and high cost-effectiveness make it a popular export product, helping businesses expand in the global plastic machinery market.
