1、Core Technology

After extensive testing on 5,000 molded products with installed electric meters, our Kaiyuan press demonstrates an average energy consumption of only 0.06 kWh per product — delivering more than 30% energy savings compared to competitor presses. This translates into annual electricity cost savings of around 3,500 USD.

Equipped with advanced oil-cooled electromagnets, the press achieves superior cooling performance and greater energy efficiency. For example, a 375-ton press requires 238,000 Ampere-Turns, enabling a powerful magnetic field at low current. With standard water cooling, each magnetic pole is fitted with a temperature sensor, eliminating the need for an additional chiller.

Beyond efficiency, our fully automatic press offers unmatched flexibility. It is fully compatible with both semi-automatic and fully automatic molds, while magnetic powder cleaning is quick and effortless. Mold changeover takes less than 30 minutes, ensuring minimal downtime and consistently high productivity.

2、Feature Highlights

Our latest patented direct servo-control demolding technology ensures that molding yield rates reach nearly 100%, while significantly boosting press productivity. Currently, with single-mold operation, cycle times are just 20–30 seconds per product (single-operator mode). With a one-to-two fully automatic model, a single operator can produce up to four products per minute.

The innovative servo demolding system also allows the press to automatically adjust demolding force when changing molds. This not only reduces reliance on operator skill but also lowers the technical requirements for mold technicians — ensuring stable, efficient, and user-friendly production.

The PLC system automatically calculates demolding parameters based on magnet block specifications, while the servo proportional-control demolding system intelligently adjusts the demolding force. This smart automation delivers superior one-shot molding results compared to conventional electric servo presses.

3、Comparative advantages of competitors

Nitrogen savings: Our fully automatic press comes standard with a nitrogen flow meter, enabling real-time monitoring of both intake and exhaust flow. Exhaust is managed through a proprietary one-way valve and a vacuum packaging system. Field tests show that, compared with competitor presses, our latest model reduces nitrogen consumption by 60–70%, while lowering oxygen content to below 500 PPM within just 20 minutes.
