Let's talk about the punch material selection of die casting machine: punch material

The most commonly used punches on the market are mostly gray iron, ductile iron, H13, SKD61, and beryllium bronze.

Punch heat treatment process

The surface hardness of the punch is recommended to be HRC45±2 degrees. If the hardness is too high, it is easy to wear the feeding barrel, leading to the early scrapping of the feeding barrel. If the hardness is too low, the punch is easy to wear and reduces the service life of the punch.

Punch lubrication effect

The good lubrication of the punch is an important link to prolong the life of the punch, so how to choose the correct lubricant and use the punch lubricant is very important. Currently commonly used lubricants include mineral oil-based graphite and graphite-free punch lubricants, synthetic-based water-soluble lubricants, and waxy granular lubricants.
Details during use

Pay attention to keep the punch cooling water pipe unblocked, pay attention to checking the cooling effect, to prevent the hammer handle from overheating and deforming, and the punch from overheating and jamming. The hardness of the punch used should be less than the hardness of the feeding barrel to avoid damage to the feeding barrel. Using special punch lubricating oil or punch lubricating particles, set the appropriate lubrication time and interval times. The hammer handle and punch should be concentric with the feed barrel. The handle of the hammer should adopt appropriate thread tolerances and be fastened to the punch.
