We are among the few manufactures in India to manufacture Zinc Gravity die castings, usually in Zamak 12 grade, which is most suitable for Gravity die castings, along with Zamak – 27.
Chief use of these Zamak 12 alloys is in the manufacture of a wide variety of Zinc Centralizer castings, used in oil drilling applications.
The “12” in Zamak 12 refers to the approx Aluminium content in this alloy and same is the case for “Zamak 27”.
These new generations of Zamak alloys are useful for thin walled Zinc castings due to their excellent fluidity. They can easily be used in the same die used for producing Aluminium LM 6 castings due to their near identical fluidity.
Surface finish is excellent and improves even further after surface finishing processes like Shot blasting, which gives a superior finish compared to Aluminium.
Weight range for the Zamak 12 castings manufactured by us is from 2 kgs to 27 kgs.
