The crushing treatment is a process that involves the fine grinding of materials using high-pressure (3-4 MPa) and high-temperature (over 220°C) steam within a pressure vessel. The heat and pressure of the steam soften the material inside the pressure vessel. The impact of the high-speed ejection during atmospheric release, along with the volume expansion of the steam that has permeated the material, crushes the material.

This is a special high-efficiency compact insert heater manufactured based on unique technology and experience. It offers high finishing precision in terms of dimensions, with a diameter tolerance of +0, -0.1mm, a length tolerance of +/-2%, and warpage of 0.3/300mmL. We have a track record of custom products with a maximum of 30KW/cm2 for high-watt cartridges. Additionally, it provides high temperature, long lifespan, and fast startup speed. We specialize in custom products such as those with built-in temperature fuses and thermocouples. For more details, please contact us or download the catalog.

• Other heaters

We introduced the technology of the original sheath heater from the U.S. company GE after World War II. Since then, our sheath heaters have built a solid track record across various industries and fields. We focus on custom products, which are in particularly high demand in the industrial sector, and have established a production system that allows us to consistently design and manufacture everything from large unit heaters to equipment. We have a strong track record in power, petrochemical, and nuclear applications, and in addition to high-quality, long-lasting products, we also possess bending processing technology that can accommodate complex shapes. *The term "sheath heater," which is now common, was named by our company.
