The injection parts stick to the mold, making it rather difficult for ejection.   Below are some reasons that caused the issue: 1. Too much injection materials. 2. Overhigh injection pressure, overlarge dwell pressure and overlong dwell time. 3. Overhigh melt temperature. 4. Overhigh mold temperature. 5. Incorrect design...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
