Cement brick highway slope protection brick laying cement tile 1: Sidewalks original soil compaction, formation, density is higher, but also add weight lane gravel layer, busy sidewalks 100-150mm thick plastic mold steel, light lane 150- 200mm thick, truck lanes 200-300 thicker than the thickness depends on the load. 2: The sand bed to play Pinto square tiles, the decomposition pressure, drainage role in the sand as well plastic mold design and manufacturing, 25-40mm thick, and be compacted plastic mold and smooth. 3: the tiles flat on the sand bed, according to the design pattern laying and retention sand sand to full fill the gaps in general can be. With the continuous improvement of the rapid development of plastic molds and general engineering plastics in terms of strength, range of applications of plastic products is also expanding, the amount of plastic products is on the rise. Statistics show that China's output of plastic products in 2012 close to 60 million tons of plastic mold, and the process continues to grow, we can see that domestic demand for China's plastic mold industry has a huge impetus. Driven by the high-tech plastic mold drive application requirements and pillar industries, forming a huge industrial chain, from upstream material industry and processing, testing equipment to machinery, auto, home appliances, electronic communications, building materials and other downstream several major application industry, plastic mold development in the ascendant. In recent years, China's plastic mold manufacturing level has been greatly improved: the weight of a single set of large plastic mold production has reached more than 50t; accuracy of precision plastic mold has reached 0.03mm; multi-cavity plastic molds capable of producing a mold 7800 plastic mold cavity; molds capable of producing high-speed extrusion speed of 4m / min over a high-speed plastic profile extrusion die and the main profile double-lumen extrusion mold.
