1. Excellent thermal conductivity and high molding efficiency
• Aluminum alloy has good thermal conductivity, which can transfer heat quickly and evenly, making the plastic sheet more uniformly heated and shortening the heating and cooling time.
• Compared with wood, resin, and other material molds, aluminum molds can significantly improve the speed of single molding, which is especially suitable for mass production and improves production efficiency.
2. High molding accuracy and stable product quality
• Aluminum molds can achieve accurate reproduction of complex structures and fine lines through precision machining (such as CNC milling, engraving, etc.). The size error is small, which can ensure the consistency of blister products.
• The surface is smooth and not easy to stick to the plastic. After molding, the surface of the molded product is flat, burr-free, and flawless, which reduces the later trimming, polishing, and other processes, and improves the product's appearance and use experience.
3. Strong wear resistance and long service life
• Aluminum alloy material has moderate hardness and good toughness. Its impact resistance and wear resistance are better than wood molds, gypsum molds, etc., and it is not easy to deform or damage due to repeated heating and pressure.
• Under normal maintenance, the service life can reach more than 100,000 times, which is much higher than that of wood molds (thousands of times) and resin molds (tens of thousands of times). The cost of long-term use is lower, which is suitable for large-scale production.
4. Strong adaptability, supporting complex structural processing
• Aluminum molds can be processed flexibly according to product design, and can adapt to the molding needs of various shaped structures (such as uneven and convex surfaces, grooves, holes, three-dimensional lines, etc.), especially suitable for precision packaging, medical device shells, automobile interiors, and other complex products.
• It can be combined with the design of cooling waterways to further optimize the cooling efficiency and avoid the deformation of the product caused by uneven cooling.
5. Easy to maintain and convenient for later adjustment
• The surface of the aluminum mold is easy to clean, and the residual plastic impurities or oil stains can be cleaned quickly to reduce the maintenance time of the mold.
• If the product design needs to be fine-tuned, the aluminum mold can be modified through secondary processing (such as local polishing, supplementary welding, and then milling), which is more flexible than one-time molds (such as plaster molds).
6. Environmentally friendly and durable, low comprehensive cost
• Aluminum alloy materials can be recycled, and the material still has a high residual value after the mold is scrapped, which is in line with the concept of environmental protection production.
• Although the initial processing cost is higher than that of wood molds, due to its long service life, less maintenance, and high production efficiency, the long-term cost sharing is lower, which is especially suitable for blister projects with medium and high output and high quality requirements.
