Rapidity and uniformity of clamping


Intrinsic safety

In the early 70s, Tecnomagnetewas the first company to invent andoffer a permanent-electro magneticsystem able to perform with highpower and in total safety forclamping and lifting ferrous parts ofany shape and size.

The early 80s Tecnomagnetefurther developed this system bypatenting the square pole circuit

with a neutral yoke calledQuadsystem.This enabled them to manufacturepermanent-electro systems moreefficient and able to satisfy thevarious requirements ofworkholding for heavy duty cuttingon machine tools.

During the 90s Tecnomagnete wasagain the first to apply suchtechnology for quick mold clampingon plastic injection machines.

The permanent electro circuitQuadsystem made with squarepoles of alternating polarizationNorth/South in a chessboardconfiguration guarantees the flat

and horizontal circuiting of themagnetic flux concentratedexclusively in the polar area.

A short electric pulse lasting some

fractions of second activatesthe system securing the clampingof the mold for unlimited timewithout consuming electricalenergy or generating any heat.Only by a subsequent electricpulse is it possible to demagnetizethe system and disengagethe mold that has been heldexclusively by the strengthof permanent magnets duringthe working session.

A mold - when magneticallyclamped - does not receive any stressor deformation as itsholding strength is equallydistributed across

the contact area insteadof the peripheral pointswhen the traditionalsystems are in use whichunavoidably also tendsto bend with heavymolds.

The combination of mold/magneticmodule/machine platen becomesa perfect match andguarantees superior

operating conditions.The absence of deflectionsin the mold and machineplatens translates to betterquality and repeatability ofthe molded parts.

Each square pole of the Quad-Presssystem is an independent magneticisland made by a steel core andsurrounded on its 5 faces byhigh energy permanent magnets

(AlNiCo + neodymium) able to generatea high value of magneto motive force(m.m.f.) concentrated and constant atindefinite period of time.The total holding force availableis directly proportional to the number ofmagnetic poles engaged with the surfaceof the mold thus always predictable.

The innovative polar geometryof QuadPress can reach the maximumoperating efficiency even on molds ofsmaller size being the polar area

concentrated in the inner surface of themagnetic module corresponding almostto the size of the smallest moldacceptable by the machine.

Ergonomical andpractical

Perfect adaptabilityQuad-Press can be easily andquickly installed on any pressby bolting the magnetic modulesto the slots or hole patternpresent on the machine platenswithout any modification.

Molds of any shape and sizeare easily clamped without anymodification of the mold baseplates, even in the presence ofprevious QMC standardization.

Quad-Press allows entire machineplatens utilization without theconstraints of the traditional moldclamps and, in some cases,the mold can even overhangincreasing the press capacity.

Smaller presses can operatelarger and more complexmolds at higher speeds.This translates intoa lower initial investment

and less operating costs.

Total Flexibility

Quick pay-back

The competitive pricecombined withthe high R.O.I.of the system allowto justify theinvestment within afew monthsof use.

A State of Art manufacturing concept accordingto the international standards (Euromap, SPI, JIS ..)

Proximity sensorsAn inductive proximity sensor located

in the neutral area detects thepresence of the mold to enable the

activationof the magnetization cycle.

The 0,2 mm (0.0078 in) threshold

value prevents any open field magnetization togrant the operator safety and it immediately

halts the machine functions in caseof mold detachment. The full safety

for the operator is also granted.

Side filling blocksRectangular steel blocksto be bolted overthe area surroundingthe magnetic module togrant the full contact withthe mold base.

As an alternative, modular round POTblocks can be provided with magneticfixturing for free positioningon the machine platens.

Lower resin levelSpecial epoxy resinwith high thermal anddynamic resistanceis used to seal themagnetic circuit.The under surface level

positioning helps to stabilizethe temperature and to avoidany possible air-gapin case of micro expansions.

Locating ringFor a quickand precisemold set up.Through holes

The monoblock frameis drilled with allthe mounting holesfor installation andthe through holesfor ejectors

Solid block

construction

The two magnetic modulesfor the stationary and moving side arebuilt with a specific milling machiningout of a solid steel plate. This gives thesystem structural stabilityand durability over time.

Specialsolutions

fordifferentapplications

DemagnetizationDuring the Demag phase

the magnetic flux is short circuitedinside the magnetic module frame,perfectly releasing the moldfor its changeover.

MagnetizationDuring the Mag phase the magneticflux is short-circuited outsidethe magnetic surface safely clampingthe mold with a very limited magneticdepth so as not to affect any internalpart of the engaged mold.

Operating phases

Neutral Yoke

The Quadsystem circuit works

with the neutral yoke principleinvented by Tecnomagnete wherethe whole magnetic fluxis concentrated exclusivelyin the polar area. The absenceof any stray flux guarantees constant

performances of the system andno trouble for the machine

and mold components.
