Klosco Solutions manufactures and installs the best cooling solutions for your metal finishing needs.

Finishing for forged metal parts is vital to manufacturing high-quality products that can withstand the rigors of industrial and commercial use. The processes of anodizing (electrochemical metallic oxide deposition), plating, and welding all generate significant amounts of heat and therefore require cooling systems.

Industrial chiller manufacturers like Klosco Solutions provide efficient metal finishing chillers for different metal finishing applications.

Applications of Metal Finishing Chillers

Metal finishing processes typically produce significant quantities of thermal energy which can adversely affect the quality of finished products if not properly dissipated. Several industrial cooling options exist which to cater to the heat created during these metal finishing procedures.

Outlined below are some applications where the use of metal finishing chillers are vital.

• Laser cooling
• Anodizing
• Paint and powder coating
• Quench cooling
• Furnace cooling
• Induction furnace coil cooling
• Die casting cooling
• Spot welding

Anodizing Cooling System

Anodizing of a metal part refers to processes that coat its exterior with a metallic film. The metal component to be treated is designated the anode of an electrolytic cell which also contains a cathode made of another element and these components are submerged in a chemical bath.

When an electrical current is passed through the setup, it dislodges metallic ions from the cathode and deposits it as a film on the anode. The thickness of the deposited layer depends on the duration of exposure of the anode within the electrically charged bath.

As earlier stated, the anodizing process will generate a significant amount of heat which needs to be eliminated from the process to ensure effective and even metallic oxide deposition.

Cold Shot’s metal finishing chillers can be effectively employed to maintain anodizing temperatures at optimal levels. The use of air-cooled chillers or water-cooled chillers alongside the electrochemical vats to achieve this result.

How Does an Anodizing Cooling System Work?

For metal cooling systems that utilize air or water-cooled chillers, alterations in the temperature within the anodizing vessel are detected by a thermal sensor fitted within.

When the amount of heat being generated by the anodizing process begins to rise above predetermined levels, controlling valves in the chiller system are opened, allowing coolant to flow through the heat exchanger causing the internal temperature to drop. These valves will also automatically shut off when optimal temperature ranges have been attained, therefore preventing the overcooling of the electrolytic process.

Spot Welder Cooling System

When resistance electrodes are used to weld a joint, the heated electrodes are subjected to very high temperatures within a very short period. The use of water-cooling systems will prevent the electrodes from undergoing premature burnout.

Typically, a water tube located within each electrode is used to maintain the welding temperatures at a stable state inhibiting electrode breakdown and poor weld strength.

Quench Tank Cooling

This technique of metal cooling involves the complete immersion of the material into a container surrounded by a heat exchanger. Heat transferred from the metallic part to the cooling tank is dissipated by the thermal exchanger through which a coolant (usually a mixture of glycol and water) from a chiller unit is circulating.

Die Cast Cooling System

Metal forging in various shapes and designs is a process that requires close thermal regulation to ensure optimal results. The typical set up for die casting cooling systems includes a cooling basin/mold into which the molten metal can be poured. Attached to this vessel is a heat exchanger that circulates chilled fluid that pulls heat away from the process.

Induction Furnace Cooling System

Various methods are currently being employed to achieve induction cooling. Most industrial induction cooling equipment uses a closed-loop setup that conveys air or water within a heat exchanger surrounding the manufacturing process.

Like other cooling systems that function with heat exchangers, induction furnace cooling systems typically utilize a glycol-water mixture as coolant. This water-cooled induction heater will help to attain the desired thermoregulation.

Chiller Sizing

To determine the size of chiller you’ll need for your metal finishing operation, follow this formula:

1. Obtain output of rectifier (Amp & Volts)
2. Obtain total BTU's Total BTU's = Amps x Volts x 3.414
3. Calculate tons of cooling capacity Tons = BTU ÷ 12,000
4. Size chiller by rounding up to the closest standard unit size

For example:

1. Rectifier output Is 1,000 Amps & 24 Volts
2. Total BTU's = 1,000 x 24 Volts x 3.414 = 81,936
3. Tons= 81,936 ÷ 12,000 = 6.83 tons
4. This application will require a 7.5-Ton unit

Plug in the following two inputs into the calculator below to get the estimated chiller size you need for your application.

• Rectifier Amperage Output
• Rectifier Voltage Output
