Hot Box Core Machines
Hot Box Core Machines for Foundry Core Making
ATD Engineering & Machine manufactures hot box core machines for foundries producing resin-bonded sand cores. Our hot box core making machines use a core shooter to blow sand into a heated core box, where the binder is thermally cured to form a rigid core. They can be configured with automated core handling, tooling, and temperature control options to suit different core designs, production rates, and plant layouts.
As an experienced hot box core machine manufacturer, ATD offers vertical-parted and horizontal-parted configurations and equipment designed for a wide range of production needs and conditions, including high-production automotive applications. ATD’s HS Series (Hot Shell) machines are dual-purpose, producing either hot box or shell cores on the same machine.

pRODUCT oVERVIEW
ATD Engineering & Machine manufactures hot box core equipment for foundries seeking controlled core production, consistent binder curing, and flexible equipment configurations. By shooting resin-bonded sand into a heated core box and applying controlled heat to cure the binder, the process forms rigid sand cores while accommodating different core designs, production requirements, and automation needs.
Key Features
- Proportional Electric Heat: Electric heaters built into the core box, with precision temperature control through electrical SSRs (solid state relays). Heating the core box electrically reduces natural gas and compressed air use, helping lower utility costs.
- Proportional Gas Control: Regulates the gas supply to help maintain precise core box temperature during operation and can help reduce gas and utility costs.
- Automated Core Unloader: Removes finished cores from the core box as part of the automated production cycle.
- Automated Core Box Scraper: Helps clean the core box during the production cycle.
- Automated Tilt and Eject with Conveyor: Tilts the core box and ejects the core onto a conveyor, with various core removal options available.
- Quick-Change Tooling Puck System: Facilitates quicker core box changeovers.
- Automated Core Wash: Automates the application of core wash as part of the production cycle.

Which Hot Box Core Machine Is Right for You?
For Vertically Parted Core Tooling
ATD's HS Series, including the HS-16, HS-22, and HS-26, may be worth evaluating when the core box requires a vertical parting arrangement. The appropriate model depends on the tooling dimensions and application requirements.
For Production Requiring Automated Core Handling
An ATD hot box machine configured with an automated unloader or tilt-and-eject system with conveyor may suit operations that need a defined method of removing and transferring finished cores. The appropriate arrangement depends on the machine configuration and core removal requirements.
For Horizontally Parted Core Tooling
The HC-16, HC-22, and HC-26 models are options to evaluate for applications requiring horizontally parted core boxes. Core box dimensions and the intended production cycle help determine the suitable configuration.

FREQUENTLY ASKED QUESTIONS
-
A hot box core machine is a foundry machine that blows resin-bonded sand into a heated core box, where heat cures the binder and forms a solid sand core used to create internal cavities in castings.
-
Hot box machines cure cores with heat from a heated core box. Cold box machines cure cores at or near room temperature by passing a catalyst gas through the sand. Hot box suits applications where heat-cured cores and proportional temperature control are preferred. See our Cold Box Core Machines page for comparison.
-
Yes. ATD’s HS Series (Hot Shell) machines are dual-purpose and can produce either hot box or shell cores. In shell core production, resin-coated sand is blown into a heated core box, and the heat melts the resin coating and bonds the sand grains to form solid or hollow shell cores.
-
A hot box core shooter is the sand-blowing system of a hot box machine. It uses compressed air to fill the heated core box with sand.
-
Proportional Electric Heat uses electric heaters built into the core box, with precise temperature control through electrical solid state relays (SSRs). This system reduces natural gas and compressed air use.
-
Proportional gas control regulates the gas supply to the core box heating system to hold a precise box temperature, and it can help reduce gas and utility costs.
-
ATD offers an automated core unloader, core box scraper, tilt and eject with conveyor and core removal options, a quick-change tooling puck system and automated core wash.
