Our molds for seals by surfcasting, are made from CNC milling machine with precision thousandth, 0.001 mm, thanks to these values accurately fused leads are perfectly balanced and concentric. There are molds for many figures of weights are already on the market and new ones, to reach long distances and sealing the bottom, a wide variety of weights available. We also have a long tail, 304 stainless steel and wire steel AISI 315L, visit the hooks.

The specific gravity was considered 10,80 Kg / dm³, averaging, as in found objects you are going to melt, type tubes for pipelines, other sinkers Fishing etc ...., there are other metals such as tin, antimony, aluminum, barium, magnesium, etc .. This means that the weights may vary from the weights of 7-8% also etched using the pure lead (weight sp.11,34 Kg / dm³).
