Inline Washers for CNC Aluminum Shell

Inline Parts Cleaning Machines are also called conveyor belt parts cleaning machines, conveyorized parts washers/cleaners, conveyor through parts washers, tunnel parts cleaners, inline parts cleaners, pass-through conveyor parts washers, and conveyor parts washers. 

This Conveyor Cleaning Machine for CNC Aluminum Shell is an automated cleaning system designed and manufactured by GTK engineers for suppliers of aluminum shell components for new energy vehicles. This specialized cleaning system is engineered for die-cast aluminum alloy workpieces, including automotive, telecom, and home appliance components.

As a high-efficiency industrial parts cleaning equipment, this system uses a conveyor belt system (e.g., mesh belts, roller conveyors) to continuously and automatically transport die-cast aluminum parts through cleaning, rinsing, and drying processes, removing various contaminants generated during production.

Contaminants To Be Removed From Aluminum Shell Components

To eliminate the Die casting release agent: Release agent usually water or oil miscible, sprayed onto the wall of the die casting mold during pressure die casting which prevents soldering of the metal to the mold and facilitates demolding of the casting.

To remove processing oil stains: Cutting fluid and lubricating oil adhered during CNC machining.

To eliminate powders and debris: Aluminum chips and burrs produced by drilling and tapping.

To remove surface oxides/fingerprints: Naturally formed oxide films, as well as fingerprints and dust from the production process.

Pre-assembly cleaning before subsequent stages: Ensures workpieces meet strict cleanliness requirements prior to assembly, laying a solid foundation for optimal product performance.

Key Features of Equipment Design and Manufacturing:

• Arrange nozzles on the top, bottom, and sides of the cleaning chamber to form a three-dimensional cross water spraying, ensuring no-dead-angle cleaning coverage for complex-structured die-cast parts.
• The sprayed fluid undergoes multi-stage filtration, which effectively filters aluminum chips and particles in the fluid, thus enabling the cleaning fluid to circulate effectively and reducing production costs for customers.
• Select specialized cleaning detergents for aluminum alloys; avoid strong acids and alkalis to prevent the workpiece surface from being corroded and forming spots
• Rinse components with DI water to eliminate watermarks and spots caused by residual cleaning detergents on the product surface after drying.
• Die-cast parts have complex structures and are prone to water trapped. Adopt the combination of “high-pressure air knife + hot air drying”: The air knife first blows off most residual water droplets, and then the workpieces enter the drying oven. Circulating hot air (temperature usually controlled at 80-130℃) ensures complete drying of the workpieces, preventing water stains and subsequent oxidation.
• Products after high-pressure drying have a high temperature, so a cooling zone is designed. The waste heat from the cooling zone is recovered to the pre-drying area through a specially configured heat energy system, realizing heat recycling and reducing energy consumption.
