— Special Processing of Precision Mold & Rapid tooling in E-Mold Rapid Manufacturing   1. EDM   Electrical discharge machining process is: between the tool and workpiece continually occur pulsed spark discharges producing local, transient high temperature, which keeps the metal melting, gasifying and removing. Sparks...read more

There is a noticeable trend towards the use of aluminium alloys for medium- to high- volume production in recently years.   The principal advantages of this material are: 1. It costs less than steel. 2. It has good machineabilty: it machines up to 5–10 times faster than steel. 3. Distortion from machining is minimal compared to...read more

Alloy steels are basically carbon steels with additional elements added to alter the characteris-tics and bring about a predictable change in the mechanical properties of the alloyed metal. Alloy steels are not normally used for most tools due to their increased cost, but some have been found favor for special applications. The alloying elements used most...read more
