1. What is a vertical aluminum shavings pressing machine?

A vertical aluminum shavings pressing machine is a specialized piece of equipment used to press loose aluminum shavings (including aluminum alloy shavings) produced by lathes, milling machines, CNC machining centers, etc., into high-density, regularly shaped (such as cylindrical or square) blocks under high pressure. The "vertical" aspect refers to the fact that the machine's main hydraulic cylinder and working pressure direction are vertically up and down.

2. Main Structure and Working Principle

Main Structural Components:

Main Frame: A robust vertical welded steel plate structure ensuring equipment stability under high pressure.

Main Hydraulic System:The core power source, including a hydraulic pump, motor, cylinders, control valves, and oil tank. Provides stable high pressure (typically ranging from 100-500 tons or higher).

Mold System:Includes the mold cavity, punch (pressing head), and discharge device. The mold determines the final shape of the pressed cake (round, square, etc.).

Electrical Control System:A PLC (Programmable Logic Controller) and touchscreen interface for setting parameters such as pressure, holding time, and operating mode (manual/automatic).

Feeding System:Typically equipped with a hopper for storing and initially conveying aluminum shavings into the mold cavity. May include a pre-pressing or spreading mechanism.

Discharge System:Pushes the pressed aluminum shavings from the mold for easy collection.

Brief Description of Working Principle:

Feeding: The operator or automatic conveyor pours aluminum shavings into the hopper.

Feeding/Placing: The aluminum shavings in the hopper enter the mold cavity below via gravity or a feeding mechanism.

Pre-compression/Pressure: The main hydraulic cylinder drives the punch downwards, applying significant vertical pressure to the loose aluminum shavings in the mold cavity.

Pressure Holding and Forming: The pressure is held for several seconds at the set maximum pressure, causing the aluminum shaving particles to bind tightly, undergoing plastic deformation, and expelling internal air and some residual cutting fluid.

Demolding and Discharge: The main hydraulic cylinder returns, and the demolding device (such as an ejector cylinder) pushes the formed dense aluminum block out from the bottom or side of the mold, completing one work cycle.

3. Core Advantages and Features

High-Density Briquetting: Compresses loose aluminum shavings to 1/3 to 1/5 of their original volume. The high density of the briquettes facilitates transportation and storage, significantly reducing logistics costs.

Reduced Oxidation Loss: The compact briquettes reduce the surface area exposed to air, thus minimizing oxidation loss (burn-off) during storage and transportation.

Improved Smelting Efficiency and Recovery Rate:

Less slag after briquettes enter the furnace, resulting in faster smelting speeds.

Reduces splashing and adhesion of aluminum shavings during the smelting process, increasing metal recovery rate by 5%-10%.

High Automation: PLC control enables automatic circulation, simplifying operation and reducing labor intensity.

Environmental Protection and Safety: The briquetting process is pollution-free, reducing fire hazards and space occupation caused by loose aluminum shavings accumulation in the workshop, maintaining a clean environment.

Significant Economic Benefits: Although it is a one-time investment, the cost can usually be recovered in a short time through cost savings in logistics, increased recovery rates, and higher selling prices for aluminum shavings (briquettes are more popular with recyclers than loose shavings). 

4. Main Application Scenarios

Aluminum product processing enterprises: Machining workshops for automotive parts, motorcycle wheels, electronic product casings, aerospace components, etc.

Aluminum profile manufacturers.

Scrap metal recycling companies: Pre-processing acquired loose aluminum shavings to increase product added value.

Any manufacturing sector that generates large amounts of aluminum alloy cutting shavings.

5. Purchasing Considerations

Pressure and Capacity: Select the appropriate tonnage (e.g., 160 tons, 315 tons, 500 tons) and unit weight/size based on the material of the aluminum scraps (different hardnesses such as pure aluminum, 6061, 7075, etc.) and the expected daily processing capacity.

Die Type: Choose a briquette shape (round cake, square brick, etc.) suitable for your storage and transportation habits. Some models support quick die change.

Automation Level: Consider whether automatic feeding devices, automatic discharge conveyors, automatic strapping machines, etc., are needed to achieve production line operation.

Hydraulic and Electrical Configuration: Pay attention to the brand of core hydraulic components (pumps, valves, seals) and PLC, as this directly affects the stability, durability, and failure rate of the equipment.

Equipment Materials and Manufacturing Process: The thickness of the steel frame and the welding process determine the long-term fatigue resistance of the equipment.

After-Sales Service: Does the supplier provide installation and commissioning, operation training, technical support, and timely spare parts supply?

Safety Protection: The equipment should be equipped with comprehensive safety devices such as safety light curtains, protective doors, and emergency stop buttons.

6. Brief Comparison with Horizontal Briquetting Machines

* Vertical: Compact structure, relatively small footprint, various discharge methods (side push, bottom push), relatively convenient maintenance, and is the more mainstream choice in the market.

* Horizontal: Typically, the main hydraulic cylinder moves horizontally, and feeding and discharging can be on the same straight line, facilitating integration into automated production lines, but may require a larger footprint.
