hydraulic parts.
This manual may include illustrations of the machine with protective covers, doors… are open or
removed in order to describe the components of the product in detail. Make sure that these parts
are looked during the machine use.
Always connect the 3 phase + ground to the machine and check the tension
before give the power (neutral where the power of the country required).
Do not remove front cover, terminal covers, cables…while the power
is being supplied. Doing so may result in electric shock.
Installation, operation, maintenance, or inspection must be performed by
authorized personnel. Not doing so may result in electric shock or injury.

Installation and Wiring Precautions
Do not step on fragile parts or place heavy object on. Doing so may
result in injury
Do not cover the inlet or outlet ports and prevent any foreign object
from entering on the machine. Doing so may result mechanical
damages, fire….
Be sure to install the product on the correct layout. Not doing so may
result in malfunction
Provide the specified clearances between all the device. Provide also
to the correctly lubrication like is indicated in the maintenance tables.
Not doing so may result in fire or malfunction
Do not apply any strong impact. Doing so may result in malfunction
Be sure to wire correctly and securely. Not doing so may result in
motor runaway, injury, or malfunction
Be sure that all mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified. Incorrect tightening torque
may result in malfunction
Always use the power supply voltage specified in electrical schema. An
incorrect voltage may result in malfunction or burning

MF 64
Author: Donato Gavino Murru [e-mail] Pag. 11 a 179
Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in
places where the power supply is unstable. An incorrect power supply
may result in malfunction
Install external breakers and take other safety measures against short
circuiting in external wiring. Insufficient safety measures short-circuiting
may result in burning
Take appropriate and sufficient countermeasures when installing the
machine in following locations
Locations subject to electricity noise
Locations subject to strong electromagnetic fields and magnetic fields
Locations subject to possible exposure to radioactivity
Locations close to power supplies
For any extra-ordinary maintenance ask to technical assistance of OMG

MF 64
Author: Donato Gavino Murru [e-mail] Pag. 12 a 179
Operation and Adjustment Precautions
Confirm that no adverse effects will occur in the system before
performing the setup or maintenance operation. Not doing so may
result in equipment damage
Check the newly set parameters for proper execution before actually
running them. Not doing so may result in equipment damage
Do not make any extreme adjustments or setting changes. Doing so
may result in unstable operation and injury
When for some maintenance you provide to demounting some parts from the
machine, must be sure to re connecting in same place and in same way that is
provided form OMG. Doing so may result in unstable operation and injury
When an alarm occurs, remove the cause, reset the alarm after
confirming safety, and then resume operation. Not doing so may
result injury
Do not come close to the machine immediately after resetting
momentary power interruption or after resetting an error to avoid an
unexpected restart. (Take appropriate measures to secure safety
against an unexpected restart.) Doing so may result in injury
Do not attempt to disassemble, repair, or modify any units before
talking with OMG. Any attempt to do so may result malfunction, fire,
or electrical shock.

Overview
Generalities about the machine –description –performances
This thermoforming line is designed to obtain products starting from a thermoplastic roll. This
material is in a film state, dragged through the process by a special high strength pin chain system.
The film advance is done by automatic cycle fully adjustable in length and time established by the
operator, according to its needs. The final product is obtaining through series of automatic steps
realize by different groups of components in the automatic process.
The first phase of the thermoforming process is called: “heating”. The plastic sheet
is heated by infrared resistors, at a temperature according to the sheet morphology
setup by the operator.
The second phase is called: “forming”. The material is transported inside the
molding tables. Tables are closing and the hot plastic is formed by the shape of the
mold.
Third phase consist of “punching” the formed sheet with a drilling station.
Fourth phase consist of “cutting” the formed sheet with a trim press.
Fifth phase is to “stack” the product that had been cut previously by the press. They
are stacked, at a preset setting choose by the operator, and extracted from the
machine, ready for being packed manually in boxes.

good working order, so they can guarantee a safety process without
any danger for the operator.
General advising
OMG forming machine was engineered to guaranty maximum security, as
indicated by laws. For that reason, if no guarding or protection are removed there
are no other dangerous areas outside the machine guarding zones.
We remind you that in compliance with the laws in effect, penetrating inside the secured
area of the machine is allowed only by skilled and authorized personnel from OMG
