Material selection and manufacturing process of waterproof enclosure
The choice of materials for waterproof shells ensures reliable waterproof performance. Usually, there are polycarbonate (PC), polyurethane (PU), silicone (Silicone), polyethylene (PE), and aluminum alloy.
The material selection and manufacturing process of a waterproof enclosure is an important factor in ensuring waterproof performance. Common waterproof enclosure material selection and manufacturing process is as follows:
Material selection:1, polycarbonate (PC): has good impact resistance and transparency, commonly used in the manufacture of cell phone waterproof enclosures.
2, polyurethane (PU): good abrasion resistance and flexibility, suitable for the manufacture of waterproof enclosures for outdoor use.
3, Silicone (Silicone): has good high-temperature resistance and flexibility, commonly used in the manufacture of waterproof earphone covers and waterproof bags for cell phones.
4, Polyethylene (PE): good corrosion resistance and low-temperature performance, suitable for manufacturing industrial use of waterproof enclosure.
Manufacturing process:
1, injection molding: the molten plastic material is injected into the mold, after cooling and curing to form the shape of the waterproof enclosure.
2, die-casting molding: the molten metal material into the mold, after cooling and curing to form the shape of the waterproof enclosure.
3、Vacuum forming: The plastic sheet is softened by heating and placed in the mold, the plastic sheet is adsorbed on the surface of the mold by vacuum, and the shape of the waterproof enclosure is formed after cooling and curing.
4, 3D printing: The use of 3D printing technology will be stacked layer by layer of plastic materials to form the shape of the waterproof enclosure.
5, bonding process: multiple parts using special glue or adhesive bonding together to form a complete waterproof enclosure structure.
For the aluminum waterproof enclosure of
PUMAY enclosure, the common material choices are as follows:
1, Aluminum alloy: Aluminum alloy is a lightweight, high-strength material, with good corrosion resistance and thermal conductivity. It is suitable for manufacturing the enclosure part of the Pumay enclosure, which can provide enough strength and stability.
2, Polyurethane (PU): Polyurethane has good abrasion resistance and flexibility, and can provide good sealing performance. Commonly used in the manufacture of PUMAY enclosureshell sealing part, to ensure waterproof performance.
3, polycarbonate (PC): polycarbonate has good impact resistance and transparency, is also a common material choice. It can be used to manufacture the visible window part of PUMAY enclosure, which is convenient to observe the internal situation.
The above are common material choices, the specific material choice should also be based on the requirements of the product and the use of the environment to decide. At the same time, attention needs to be paid to the coordination between the materials and process cooperation to ensure the waterproof performance and reliability of PUMAY enclosure.
The
manufacturing process of the aluminum profile waterproof enclosure of PUMAY enclosure is as follows:
1, aluminum extrusion: The aluminum alloy billet is heated to a certain temperature, and then the aluminum alloy is extruded through the extrusion die to form the enclosure structure of PUMAY enclosure.
2, CNC machining: the use of CNC machine tools on the aluminum profile for accurate cutting, drilling and other machining processes, the formation of PUMAY enclosure shape and holes.
3、Welding: Argon arc welding or laser welding of aluminum profiles to weld different parts together to form a complete PUMAY enclosure structure.
4、Surface treatment: anodic oxidation, spraying, and other surface treatment processes for aluminum profiles to improve the corrosion resistance and appearance of the PUMAY enclosure quality.
5、Sealing treatment: Use polyurethane sealant or sealing strip to seal the joints of aluminum profiles to ensure the waterproof performance of the PUMAY enclosure.
6、Assembling and testing: assembling the parts together, testing and debugging to ensure that the function and performance of PUMAY enclosure meet the requirements.
The above is the common manufacturing process of aluminum waterproof enclosure of PUMAY enclosure, the specific manufacturing process also needs to be based on the requirements of the product and design to decide. At the same time, it is also necessary to pay attention to the quality control of the manufacturing process to ensure the waterproof performance and reliability of Pumay enclosure.
