RHCM高光過熱水模溫控制機

RHCM superheated water high-gloss traceless injection mould

急速升降模溫技術(shù)

Technology of quick rising and drop of mold temperature

傳統(tǒng)注塑模具溫度控制的不足之處如下

Disadvantages of the traditional temperature control technology for injection molds:

無法滿足高光注塑中快速升溫及快速降溫的需要。

The need of high-gloss injection molding for quick temperature rising and drop cannot be met.

升溫幅度較小，制品表面的溶接痕只能得到減輕而無法消除。

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，流動性越差。因此采用此種工藝，制品表面的硬度只能達到HB級，無法滿足實際使用需要。

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.

模具升溫時受熱膨脹，降溫時又會收縮，使鎖模力很不穩(wěn)定。

Due to the mold’s expansion when in temperature rising and its shrinkage when in temperature drop, the clamping force is quite unstable.

容易造成制品打不滿，燒焦、內(nèi)應(yīng)力大等各種缺陷。

Thus, the products are easy to suffer from short molding, scorching, excessive internal stress and other defects.
