Although these pouring temperatures are considered high for magnesium, the goal was to completely fill these patterns without cold lap or misruns.
The objective is to detect any pre-existing condition at the origin that may have led to crack formation (such as an inclusion, cold lap, micro hot tear, etc.
Since the TENBLOC alloy is mixed to precise grades and chemistry, it is virtually guaranteed to eliminate chemical segregation, slag, blow hole, cold lap and shrinkage defects common to other solid cast inserts.
Produced to a precise shape and size, block weight is closely controlled resulting in minimal slag while reducing oxidized blow holes, cold lap and shrinkage defects.
Other types of defects such as cold laps, cold shots and re-oxidation products, previously caused by metal flow, also were significantly reduced.
