Here we are sharing details explanation of Disc brake Manufacrturing using CORE BOX and Casting Pattern.
Pattern casting and core boxes are critical tools in automotive manufacturing, allowing for precise, efficient, and cost-effective production of metal parts. Advances in 3D printing and digital modeling are also improving these processes, leading to better designs and reduced production time.
Triethylamine cold core process is a rapid core-making process using triethylamine gas to harden phenolic resin sand.It will widely used like brake disc core making, motor housing casting, pump housing casting.
CORE: A core is a pre-formed structure used in casting to create internal cavities, passages, or intricate shapes in metal components. It is placed inside the mold before metal is poured, and after solidification, it is removed by breaking or dissolving. cold box core shooter machine is horizontal parting,Sand solidify by Amine gas.
Patterns are horizontal parting, Top Shooting sand and Blowing gas, Amine gas generator can let Triethylamine is fully vaporized.
A core is a pre-formed structure used in casting to create internal cavities, passages, or intricate shapes in metal components. It is placed inside the mold before metal is poured, and after solidification, it is removed by breaking or dissolving.
Why Are Cores Used?
- To create hollow sections in Disk Brake and Drum Brake parts.
- To form cooling and lubrication channels inside cast components.
- To reduce the weight of automotive parts while maintaining strength.
- To enable complex geometries that would be impossible with traditional molds.

- Sand is mixed with a thermosetting binder and heated to form the core.
- Used in mass production of automotive castings for Disk Brake.


A casting pattern is a replica of the final brake disc but slightly larger to account for metal shrinkage.
The pattern includes details like:
- Mounting holes for the hub
- Ventilation slots (if using a split mold)
- Outer braking surface dimensions
Mold Preparation (Creating the Sand Mold)
- The mold cavity is created by packing sand around the casting pattern inside a molding box.
- Once the sand is compacted, the pattern is removed, leaving behind a negative impression of the disc brake.
- The sand cores (if needed) are placed inside the mold to form internal cooling passages.
- The mold halves are closed and securely clamped to prepare for casting.
