| Message: | The cavity and core of this mold are made with hard alloy. Low-speed WEDM is used for internal processing of the cavity to sub-mirror effect, and then abrasive flowing machine for polishing to the mirror effect; similarly, low-speed WEDM is used for processing of the mold core and mirror pulse lath for processing of irregular points to sub-mirror effect before polishing to the mirror effect; both upper and low punches are made with HITACHI high-speed steel with HRC up to 61-63 degrees; electrode is made with the processing center, processed with mirror pulse lathe to sub-mirror effect, then polished to mirror effect, and finally protected with wear-resistant coating to add 100% service life. url:http://www.yxhgmould.com |
