Semco has been making custom chill vents and chill blocks for many years.
Our Chill products are designed to maximize product strength and density while providing consistent air relief. Porosity is a major issue for die casters and a quality chill vent specifically assists in controlling porosity and enabling more complex parts to be made.
Semco will provide any customer with either our own design, sized to fit your machines or make according to your individual specifications.
In any case, our foundry manufactures the absolute highest quality chill vents and blocks in the industry.
