Corner boards
when designing Efficiency:
+ The product is cooled evenly
+ Reduced product capabilities warping
+ Reduce the drag line
+ Simplified stress concentration
+ Plastic easy filling liquid cavity
Some things to note the
radius of boron should be in the range from 25% to 60% the thickness of the product, but the best is 50%. Outer radius radius should equal the thickness of the card slots:
R = r + T
Once this is unsatisfactory, the product will be warped by the plastic cools unevenly between the inside and outside of the product makes the uneven shrinkage. Add to that the stress concentration and
