1. Design and drawing: First, according to the size and shape of the refrigerator, design the structure and shape of the mold, and draw detailed drawings. This process needs to use computer-aided design software to optimize the mold design according to the actual situation.
2. Cutting materials: cutting the required raw materials into corresponding sizes and shapes, such as mold body, mold frame, mold core, etc. At the same time, it is necessary to cut out the parts that need to be inserted into the mold from these materials.
3. Welding forming: welding and assembling the cut materials into a mold body and a core. This is the most critical step in the mold making process, and professional welding tools and skills are needed to ensure the stability and accuracy of the mold.
4. Machining surface: polish, trim and coat the mold surface to make it smooth, beautiful and corrosion-resistant. This process requires the use of a variety of processing tools and technologies, including polishing, spraying, electroplating and so on.
5. Debugging and testing: After the mold is made, it needs to be tested and adjusted to ensure that it can be used perfectly with the refrigerator backboard and other components. This process requires the use of a series of measuring and testing tools, including three-coordinate measuring instruments, oscilloscopes and so on.
To sum up, Zhejiang refrigerator mold making is a process that requires high professional skills and experience, and every step and detail need to be carefully considered to ensure that the final mold quality and accuracy are high and can meet the needs of refrigerator production.
