some tips in operating EDM
This creates craters in both electrodes, the size of which are related to the energy of the spark. Thus, a distinction is drawn between roughing with high impulse energy and planning. […]
gun drilling and ordinary drilling
So far deep hole drilling( gun drilling) has been used more and more widely in injection molds. This method requires a special machine or a deep hole drilling adaptor to another machine, […]
modern mold making
modern tooling machines for mold making generally feature multiaxial CNC controls and highly accurate positioning systems. the result is higher accuracy and greater efficiency against rejects. […]
the surface quality of a plastic part
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 [...]
high-speed cutting and simultaneous five-axis milling
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 [...]
a combination of milling and eroding in a mold manufacturing
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
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, […]
what is the BOM in a mold enterprise ?
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, […]
introduction to mold material flow
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 and mold steel
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), […]
