Precast concrete bread magnets are special bread-shaped template magnets specifically designed for use with rail molds or plywood templates. With the addition of a multi-functional adapter, the bread magnets can be effectively secured, ensuring a tight fit with the side mold. Equipped with a special release tool, the magnets can be easily placed in the correct position. Its working principle is based on a unique pressure point effect, where pressure points on the inside of the template grip the beveled surface of the tapered magnet. This gives all U-shaped templates shock and vibration protection. Various chamfering treatments are available. Draft angles can be adjusted as needed. Hopper recesses and slots can be set for all common robotic systems.
