BLK SERIES Water chiller

The ZHY series’ press machine, with integrated mold pressuring technology, is used for boric

acid, steel ring, aluminum cup, plastic ring and low-pressure polythene pressuring.

Our unique slow-pressurization and slow-decompression program is essential to produce high-

grade samples.

The automatic slow-pressurization: When there is excess space, the press head will move

upwards quickly and as the space between the press head and sample decreases, the press slows

down and begins slow pressurization until it achieves the set upper limit. This process causes

the air to be removed and the compression of the sample to be even thus enhancing the overall

quality of the sample.

The automatic slow-decompression: When the slow pressurization is completed, the press

begins slowly releasing pressure as the press head moves downward automatically. Without this

unique slow decompression procedure, a vacuum between the fast moving press head and the sample

would be created, pulling and dispersing the sample unevenly. After the press head is out of

contact with the sample, the head falls quickly, providing an efficient means of production.

ZHY- 401A/601A press machine uses PLC (programmable controller) to accuracy control and

demonstrated active status at times. ZHY- 401A/601A automatic pressuring according to

procedure.
