2 DESCRIPTION OF THE MAYKU MULTIPLIER
2.1 Intended use and reasonably foreseeable misuse
The Multiplier is intended to be used as a desktop pressure forming machine, for making high
detail molds from suitable templates for a range of applications.
The Multiplier is intended for indoor use in a well ventilated area only.
Unintended uses:
●The machinery shall only be used for applications as described by the manufacturer. All
other applications are unprofessional and considered dangerous. The manufacturer
cannot be held liable for damage resulting from errors, unintended or unprofessional use
of the machinery.
●This machinery is not intended for use by persons (including unsupervised children) with
restricted physical, sensory or intellectual capability or lack of experience and/or
knowledge.
●Only use the machinery within the specified performance limits as described in these
instructions.
●An external compressor shall not be connected to this machine under any
circumstances. This may result in injury or death.
The Multiplier shall only be used in accordance with the instructions described in this
installation and user manual. Any use other than those described in these documents is
considered as unintended use. Unintended use will invalidate the warranty.
2.2 System overview
The Multiplier is loaded with sheets of thermoplastic which are locked into the machine and
heated past their glass transition temperature using an infrared heating element. Once at the
required temperature the lid is locked, and up to 60 PSI of pressure is applied into the dome and
to the sheet. This pressure is generated by a compressor which stores air inside internal tanks.
The pressure is then vented through a silencer and the sheet is left to cool before removal.
