DECORING UNIT/ DECORING STATION
DC-70 De-coring Machine
The DC-70 decoring machine uses high-frequency decoring hammers to strike the casting sprue, breaking the internal sand core into pieces. The fragments then flow out through the sand outlet, achieving fast removal of the casting’s internal sand core.
The operation is efficient and labor-saving, while ensuring the casting remains intact and its surface quality is maintained. It is an ideal choice for modern casting sand removal.
Rotation and Hammering for Core Sand Removal
DC-70R Rotary De-coring Machine
This DC-70R Rotary Decoring Machine combines high-frequency pneumatic hammering with a rotating mechanism. The casting rotates while being hammered, promoting the breakup and discharge of the sand core. It is well-suited for aluminum alloy castings with relatively simple internal cavities.
Hammering and High-Frequency Vibration for Core Sand Removal
DC-70V Vibration De-coring Machine
This DC-70V vibration decoring machine is designed for removing sand cores from aluminum alloy castings such as cylinder heads, swing arms, sub-frames, housings, and air pipes. The decoring process combines hammering with high-frequency vibration for efficient and thorough sand removal.
Rotation, Hammering, and High-Frequency Vibration for Core Sand Removal
DC-70VR Rotary & Vibration De-coring Machine
The DC-70VR rotary vibration decoring machine combines hammering, rotation, and high-frequency vibration for efficient sand core removal.
During operation, the decoring hammer strikes the casting sprue at high frequency, loosening the internal sand core. The coordinated vibration and rotation then break the core into pieces and discharge it through the sand outlet, ensuring complete and thorough decoring.
