The die casting process of cookware involves forming metal (usually aluminum alloy) into a specific shape through a mold. This process ensures that the cookware has excellent thermal conductivity, durability and beautiful appearance. The following is the detailed process of cookware die casting: 1. Material preparation Metal raw materials: Aluminum alloy is usually selected because of its light weight and good thermal conductivity. Alloy smelting: The aluminum alloy is melted in a furnace and appropriate alloying elements are added to improve the mechanical properties and corrosion resistance of the material. 2. Mold design and production Mold design: The mold is designed according to the shape and size of the cookware. The mold needs to have high precision and high temperature resistance. Mold production: The mold is made of high-strength steel and finely processed to ensure that the mold surface is smooth and meets the design requirements. 3. Mold preheating Before die casting, the mold is preheated. Preheating helps the metal to be more evenly distributed when injected into the mold, reducing pores and cold shut defects. 4. Die casting Metal injection: The molten aluminum alloy is injected into the preheated mold through the die casting machine. High pressure causes the metal to quickly fill the mold and form the basic shape of the pot. Cooling and solidification: Maintain high pressure and wait for the aluminum alloy to cool and solidify, usually a few seconds to a few minutes. 5. Demolding Once the metal cools and solidifies, open the mold and carefully remove the formed pot blank. 6. Post-processing Trimming and deburring: Remove excess material and burrs generated during the die-casting process to make the edges smooth. Machining: Further processing such as drilling, turning and milling is performed as needed to ensure dimensional accuracy and surface finish. 7. Surface treatment Polishing and grinding: Polish and grind the surface of the pot to enhance its gloss and beauty. Spraying or electroplating: Spraying or electroplating treatment is performed according to product requirements to increase the appearance effect and improve corrosion resistance. Non-stick coating: Many pots need to be coated with non-stick coating to ensure that food does not stick to the pot during cooking. 8. Quality inspection Strict quality inspection of the finished product to ensure that it meets the design specifications and quality standards. Inspection items include appearance inspection, dimensional measurement, coating adhesion test, etc. 9. Packaging and Shipping Qualified cookware is packaged to prevent damage during transportation and is ready to be shipped to customers or retailers. Through the above steps, manufacturers can produce high-quality cookware to meet market demand and ensure that consumers have a good experience during use.

There are some differences in the principle of refrigeration and working methods of air-cooled screw-type cold water machines and air-cooled cold water machines. It is mainly reflected in the type of compressor and refrigeration method: 1. Compressor type: Wind-cold screw-type cold water machine: Use screw compressor as the core component of the refrigeration system. The screw -type compressor compress the refrigerant through the rotation of the screw, which has efficient and stable refrigeration performance and is suitable for a large refrigeration system. Cold-cold cold water machine: Usually a reciprocating compressor or screw compressor. Compared with the screw -type cold water machine, the type of compressor of the air-cooled cold water machine may be more diverse, but in some cases, the reciprocating compressor may be lower than the screw compressor, but the efficiency is usually lower. 2. Refrigeration method: Wind-cold screw-type cold water machine: Use a fan to flow the air over the condenser, so as to cool the refrigerant and distribute the heat into the environment. This method can save water resources and suitable for the scene of water -free cooling system. Cold-cold cold water machine: It also uses a fan to flow the air over the condenser, but its compressor type may not be limited to screw type, which can be duplex. This method can also distribute heat into the environment, but in some cases, more water resources may be needed to maintain the cooling effect. In summary, the air -cooled screw -type cold water machine has some differences in the type and cooling method of the compressor and the cooling method. Screw -type cold water machines usually have higher energy efficiency and stability, suitable for the requirements of large refrigeration systems, while air-cooled cold water machines may have some advantages in the cooling method and cost, suitable for the needs of small and medium-sized refrigeration systems.

Spot coolers and mold temperature controllers are two common devices used to control mold temperature. They have some differences in working principles and application scenarios: 1. Cooling machine: Working principle: The spot cooler controls the temperature of the mold by directly injecting refrigerant into the cooling channel in the mold. The refrigeration process is usually accomplished using components such as compressors, condensers, evaporators, and control systems. Application scenario: The spot cooler is suitable for scenarios where precise control of mold temperature is required, especially for large and complex molds and production processes that require high product quality. Spot coolers generally provide greater temperature control accuracy and stability. 2. Mold temperature controller: Working principle: The mold temperature controller circulates the heat transfer medium (usually water or oil) through the cooling channels of the mold to absorb or release heat to control the temperature of the mold. The mold temperature controller includes heating elements, circulation pumps, control systems and other components. Application scenario: Mold temperature controller is suitable for situations where the mold temperature requirements are not too strict, such as in plastic injection molding, die-casting and other production processes. Mold temperature controllers generally provide relatively low cost and simpler operation, but the temperature control accuracy may not be as high as that of spot coolers. In general, spot coolers are suitable for production scenarios with higher mold temperature control requirements, while mold temperature controllers are more suitable for general mold temperature control needs. The choice of which equipment to use should be determined based on specific production needs, mold design and product quality requirements.
