近年来人们对各种设备和用品轻量化、美观和手感的要求越来越高,为塑料模具设备提供了更为广阔的市场,塑料模具行业发展进入应景期.路沿石模具成型的制件表现出高精度、高复杂性、高一致性、高生产率和低消耗,塑料模具的加工制造方法有其独特的创造价值.塑料模具在很大程度上决定着产品的质量、效益和开发能力. In recent years, people of all kinds of equipment and supplies lightweight, beautiful and feel the demand is higher and higher, provides a wider market for plastic mould, plastic mould industry into the relevant period. Lu yanshi molding parts show the high accuracy, high complexity, high consistency, high productivity and low consumption, the plastic mold processing and manufacturing method has its unique value. Plastic mold to a large extent determines the product quality, efficiency and development ability. 　　新型多功能路沿石模具除了冲压成型零件外,还担负叠压、攻丝、铆接和锁紧等组装任务,对钢材的性能要求也越来越高.四是热流道模具在塑料模具中的比重逐渐提高.由于采用热流道技术的模具可提高制件的生产率和质量,并能大幅度节约制作的原材料,因此热流道技术的应用在外国发展很快,许多路沿石模具厂生产的塑料模具一半以上采用了热流道技术,有的厂家使用率达到80%以上,效果十分明显.热流道模具在我国也已生产,有些企业使用率上升到20%——30%. New-type multifunctional luyandan mould in addition to stamping molding parts, also take the overlying, tapping, riveting, and lock assembly tasks, such as performance requirements for steel is becoming more and more high. The proportion of four is hot runner mold in plastic mould gradually improve. Due to the mold hot runner technology can improve the productivity and quality of parts, and can greatly save the production of raw materials, so the application of hot runner technology developing rapidly in foreign countries, many luyandan mold factory production of plastic mold half used hot runner technology, some manufacturer utilization rate above 80%, the effect is very obvious. Hot runner mold have production in our country, some companies use up to 20% - 20%.
