| Electro-Permanent Magnetic Chuck For Plastic Injection Machine |
 |
Magnetic platens were processing on CNC with a Block plate, more compact , more rigid , more firmly. |
| |
 |
Through Holes
The mounting holes for installation and the through holes for ejectors clearance on the moving platens and injection nose hole |
Proximity Sensors
An inductive proximity sensor located in the “neutral” area detects the presence of the mold to enable the activation of the magnetization cycle. The 0.2 mm threshold value prevents any “open field magnetization” to grant the operator safety and it immediately halts the machine functions in case of mold detachment. |
Lower Resin Level
Special epoxy resin with high thermal and dynamic resistance is used to seal the magnetic circuit. The under surface level positioning helps to stabilize the temperature and to avoid any possible “air-gap” in case of micro expansions. |
Fcs Sensor
To check the value of the magnetic flux saturation reached by some poles and to enable the machine work. |
Locating Ring
For a quick and precise mold set up |

Mold set up ready to work in a very short time.
EPPLC made with square poles of alternating polarization North/South in a chessboard conf igurat ion guarantees the flat and horizontal circuiting of the magnetic flux concentrated exclusively in the polar area.
A short electric pulse lasting some fractions of second activatesthe system securing the clamping of the mold for unlimited time without consuming electrical energy or generating any heat. Only by a subsequent electric pulse is it possible to demagnetize the system and disengagethe mold
that has been held exclusively by the strengthof permanent magnets during the working session. |

Magnetization
During the Magphase, the magnetic flux is short -circuited outside the magnetic surface, safely clamping the mold with a very limited magnetic depth, so as not to affect any internal part of the engaged mold.
Demagnetization
During the Demag phase, the magnetic flux is short circuited inside the magnetic module frame, perfectly releasing the mold for its changeover. |
 |
| A mold - when magnetically clamped - does not receive any stress or deformation as its holding strength is equally distributed across the contact area, instead of the peripheral points when the traditional systems are in use which unavoidably also tends to bend with heavy molds. |
Each square pole of the EPPLC system is an independent magnetic island made by a steel core and surrounded on its 5 faces byhigh energy permanent magnets (AlNiCo + neodymium) able to generate a high value of magnetic force concentrated and constant at indefinite period of time.
The total holding force available is directly proportional to the number of magnetic poles engaged with the surface of the mold thus always predictable.
Even if the size of the mould is smaller because the pole is highly concentrated in a region is also acceptable. |
