after heat treatment, the machined inserts are finished, ground and polished to obtain a good surface quality,because the surface conditions of a cavity are, in the end, responsible for the surface quality of a plastic part and its ease of release. Defects in the surface of the cavity are reproduced to different extends depending on [...]
competition has recently developed between high-speed cutting(HSC) and simultaneous five-axis milling. HSC is characterized by high cutting speeds and high spindle rotation speeds. Steel materials with hardness values of up to 62HRC can also be machined with contemporary standard HSC millers. Sometimes, HSC machining can be carried out as a complete machining so that the [...]
for the production of injection and die-casting molds, a combination of milling and eroding may also be performed. The amount of milling should be maximized since the machining times are shorter on account of higher removal capability. However, very complex contours, filigree geometries and deep cavities can be produced by subsequent spark-erosive machining. The electrode [...]
the mold industry lays great emphasis on efficiency. Sometime, considering the credit therein, even when business negotiation between the manufacturing and the customers is still under way, […]
the BOM table takes mold products as the unit, namely, mold products recorded in the same BOM table are of the same serial No, and are distinguished by material No, […]
Generally, when the number of staff of a mold manufacturing enterprise reaches 100, a network collaborative mold manufacturing system shall be required, wherein the management of mold materials is one of the most essential parts. […]
mold parts without special requirements can be manufactured from carbon structure steel( such as Japan’s S45C, S50C, and S55C) or carbon tool steel(such as Japan’s SK series), […]
the service hardness of pre-hardened steel is usually within the range of 30—42HRC, wherein the cutting property is not good under high hardness, […]
Some plastic mold steels after being processed and molded will deform dramatically during heat treatment, whereby the precision of molds cannot be ensured. […]
when molding plastics of particularly large abrasion force, the abrasion may still be rather serious even if high carbon or high chrome is used. […]
