高光无夹线无痕注塑技术的详细介绍 高光过热水无熔痕注塑系统/高光无夹线无痕注塑技术/高光蒸汽(无熔痕)注塑系统 RHCM高光过热水模温控制机 RHCM superheated water high-gloss traceless injection mould 急速升降模温技术 Technology of quick rising and drop of mold temperature 传统注塑模具温度控制的不足之处如下 Disadvantages of the traditional temperature control technology for injection molds: 无法满足高光注塑中快速升温及快速降温的需要。 The need of high-gloss injection molding for quick temperature rising and drop cannot be met. 升温幅度较小，制品表面的溶接痕只能得到减轻而无法消除。 The margin of temperature rising is very small. As a result, the welding traces on product surfaces can be alleviated rather than removed thoroughly. 由于塑料硬度越高，流动性越差。因此采用此种工艺，制品表面的硬度只能达到HB级，无法满足实际使用需要。 Due to the great hardness and poor fluidity of plastics, this technology can only make the surface hardness of a product grade HB, failing to meet the actual requirements of application. 模具升温时受热膨胀，降温时又会收缩，使锁模力很不稳定。 Due to the mold’s expansion when in temperature rising and its shrinkage when in temperature drop, the clamping force is quite unstable. 容易造成制品打不满，烧焦、内应力大等各种缺陷。 Thus, the products are easy to suffer from short molding, scorching, excessive internal stress and other defects.
