Use this calculator to work out the weight of a mould given the size and material density.

This tool is useful for working out crane lifting requirements as well as compatibility with a moulding machine. Consult your moulding machine technical data for maximum mould weights.

Density table is given below for some steels. For a more accurate answer source your own density data.

P20 Mold steel: 7.85 grams/cubic cm or 0.2836 lbs/cubic inch

H13  steel : 7.80 grams/cubic cm or 0.2818 lbs/cubic inch

Stainless steel: 8.03 grams/cubic cm or 0.2901 lbs/cubic inch
