Company Profile

Xiamen Xinghongjiye Machinery Manufacturing Co., Ltd. is a high-quality machinery manufacturing

enterprise with the ability to produce and develop cemented carbide series equipment. Founded in 2019,

it is located in the beautiful Xiamen Island. The main products are sintering equipment, coating equipment, precision grinding machine, testing equipment and so on.

XIAMEN HJ CARBIDE TECHNOLOGY CO.,LTD.is a high-quality enterprise that produces

cemented carbide rods, cutting tools, and equipment. Its main equipment includes sintering

furnaces, coating furnaces, precision grinders, and testing equipment.

Pressure sintering furnace

Safe and reliable:

Over-temperature alarm self-locking,

over-pressure alarm self-locking,

positive pressure leak detection,

negative pressure leak detection.

6Mpa/10Mpa/20Mpa (selectable)

2000°C

Rapid cooling

A more thorough degreasing

solution (customizable)

High degree of automation:

The entire technological process is automatically

controlled by a computer, with one-click start-up,

real-time dynamic monitoring, tracking,

self-diagnosis of faults, simulation display and

record saving (temperature, pressure, vacuum

degree, etc.). Sintering and dewaxing are carried

out in an integrated manner.

Application fields:

Sintering of ceramic materials such as silicon

nitride, alumina and aluminum nitride

Sintering of cemented carbide
