Key Technologies and Configurations

Hydraulic press (with Pre-Compression Cylinder): This is the core feature that distinguishes this machine from other machines.

Benefits: Before the main cylinder's high-pressure pressing, the pre-compression cylinder squeezes out most of the cutting fluid/oil from the chips. This significantly increases cake density (by removing air), reduces grease dripping, and ensures purer recovered cutting fluid. If your chips contain a lot of oil/fluid, a machine with this feature is highly recommended.

Control Methods:

Manual/Semi-Automatic: Lower cost, requiring manual control of each step.

Fully Automatic (PLC Control): After program setup, a single button starts the process, automatically completing all steps—feeding, pressing, holding pressure, and demolding. High efficiency and low labor intensity make this the preferred choice for modern workshops.

Feeding Box Capacity and Feeding Method:

Feeding Box Size: Determines the amount of chips that can be processed at a time.

Feeding Methods: Top loading and automatic conveyor feeding are available. For high-volume applications, an automatic feeder can significantly improve efficiency.

Hydraulic System Quality:

Component Brand: Ask about the brands of key hydraulic pumps, valves, and cylinders. Using equipment from reputable brands (such as Rexroth) ensures greater stability and longevity.

Structure and Materials:

Frame: What thickness of steel plates are used for welding? Is it sufficiently rigid to prevent deformation during long-term use?

Molds (die and punch): Are they made of high-strength alloy steel and heat-treated? This directly affects wear resistance and service life.
