First, imported high-quality silicone raw materials are selected and processed with mature scientific formulas and skilled processes. It has moderate viscosity, good fluidity, easy operation, and convenient various treatments during the production process.
Secondly, the shrinkage rate is small, only 0.1-0.3%, which can ensure the stability and accuracy of the mold size.
Furthermore, the hardness is moderate, making the mold easy to demold and not deform, which is very important for improving production efficiency and ensuring tire quality.
In terms of raw materials, it is mainly high-quality steel or alloy steel, because of its excellent hardness, heat resistance and durability, it can withstand high temperature and high pressure in tire molding, ensure the shape and integrity of the mold in multiple production cycles, and provide accurate and consistent tread patterns and sidewall designs. Some molds may have additional coatings or surface treatments to enhance wear resistance and demolding.
From the manufacturing process point of view, traditional processing methods face challenges, and additive manufacturing technology brings breakthroughs. For example, it can print 3D steel sheets to achieve various complex shapes and textures. The same batch can print steel sheets of various sizes and shapes, personalized batch production, improve the utilization rate of the printing plate, reduce the cost of each piece, and directly print the entire pattern mold, integrated production, and simplify the process.
In use, tire molds are divided into various types, and vulcanization is suitable for patterns according to structural characteristics. When connected to the vulcanizer for production, it is necessary to check the gaps between each part, such as the gaps between the pattern blocks, side plates, and live blocks, check the vents to ensure the exhaust volume, pay attention to the lubrication and periodic maintenance between the parts, use high-temperature resistant lubricants, and regularly apply oil to the bow seat, wear-reducing plate and other positions.
