Is designed to improve the quality of mold slope and most important step herringbone slope mold, choose the best possible solutions hexagonal brick structure slope mold design should be reasonable, taking fully into account the part of the technical requirements of trench cover mold slope of the material choices necessary to meet the customer's quality requirements, the need to take into account the cost of materials and their strength within a set period, and the type of mold, the use of work, processing speed, the main failure mode and other factors. Since the high-strength steel in yield ratio, strain hardening behavior, strain distribution capacity and the crash, and so has excellent characteristics, a wide application of high strength steel. The amount of the car increased from time to time. Currently, high-strength steel used in the automotive stampings mainly paint hardened steel (BH Steel) dual-phase steel (DP steel) transformation induced plasticity steel (PIP steel) and so on. Need to overcome the high-strength steel stamping technology, now widely adopted to IF steels mainly mild steel series will be low-high strength steel series of alternatives, will be replaced by a high-strength alloy steel and ultra high strength dual-phase steel. At present, the application of the domestic auto parts high-strength steel structure is still mostly limited to the beam type parts, the tensile strength of the material used in 500MPa much less. Therefore, an important issue quickly master high-strength steel stamping technology, country slope mold industry to be solved. Herringbone slope mold _ Li Chen mold (certified) _ slope mold provided by the city is the county Li Chen plastic mold factory. Mancheng County Lai Chen plastic mold factory (www.baodingchangda.com) Hebei Baoding, plastic building materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Korea the morning mold leadership with the staff warmly welcome all inquiries negotiations to create Lai Chen mold a better future.
