Mold Positioning Magnets

Mold positioning magnet is a type of magnet used in molds or machine equipment, mainly for precise positioning, fixing or adjusting mold components. It can be installed on the mold frame or cavity to firmly fix the mold in place during the manufacturing process. Especially in the manufacturing processes of plastic injection molding, stamping, casting, etc., high-precision positioning and fixation are often required.

The main features of mold positioning magnets:

1. Strong magnetic force: mold positioning magnets usually use powerful rare earth magnetic materials (such as neodymium iron boron or samarium cobalt), which can provide stable and strong magnetic force to ensure the stable positioning of the mold.

2. Convenient installation and disassembly: Due to the characteristics of the magnet itself, mold positioning magnets are very easy to install and disassemble, saving labor and time, and improving work efficiency.

3. High temperature resistance: many mold positioning magnets are designed with high temperature environment in mind, using high temperature resistant materials, able to work stably under high temperature conditions such as injection molding or casting.

4. Wear-resistant: In order to adapt to long time and high intensity use, mold positioning magnets usually adopt wear-resistant surface coating to prolong the service life.

Commonly Used Shapes of Mold Positioning Magnets - Circular

Common magnet shapes for mold locating magnets are round and block. Round shapes are commonly used for round or curved mold parts. Square shapes are used to locate square or rectangular molds, providing a larger contact area.

Mold positioning magnet selection considerations;

It is necessary to select the appropriate magnetic force according to the weight and size of the mold to ensure solid positioning.

If the application needs to be in a high-temperature environment, select magnets with good high-temperature resistance, e.g., >120°C.

In terms of mounting, some mold locating magnets are designed to be held in direct contact with the surface of the mold and are suitable for applications where a quick mold change is required. Some mold locating magnets need to be embedded in special locations in the mold. This requires that the mounting method of the magnet be considered at the time of design to ensure adaptability and stability.

Benefits of Mold Positioning Magnets:

1. Improved accuracy: Ensures precise alignment of mold components.

2. Time saving: facilitates fast and efficient mold changes.

3. Cost-effective: reduces downtime and maintenance costs.

4. Increased productivity: improves overall productivity.

5. Versatile: suitable for all types of molds and industrial applications.
