Jan 18, 2020 The most common type of core is a dry sand core. The basic process for making a dry sand core is by packing sand into a core box essentially a mold and then hardening it. The core is then supported in a mold by means of core prints or chaplets and the molten metal is poured into the mold, creating the desired iron casting.

Powdered natural rosin was traditionally used as a binder in core sands. Core-making methods. Cores are made by many of the same methods employed for sand molds.In addition, core blowers and screw feed machines are used. Core blowers force sand into the core box by compressed air at about 100 lbin 2.They can be used for making all types of small- and medium-sized cores.
