Toyo Metal &
Machinery offers Special Machine and Process
to meet your Demands
Toyo offers multi-component
machines using the standard "Si II"
series or "H" series injection molding
machine as the base machine, with the second
injection unit (electric) servo mounted horizontal
to parting line non-operator side of press.
Machines can be supplied with or without rotating
« MuCell® Microcellular
has licensing agreement to supply "Si
II" series electric injection molding
machines utilizing Trexel's propriety MuCell™ microcellular
foam processing technology. Using inexpensive,
environmentally friendly supercritical fluid
(SCFs) of atmospheric
gases CO2 or N2 as
blowing agents, the MuCell process produces
evenly distributed and uniformly sized microscopic
cells (5-50 microns in diameter). MuCell process
can reduce material usage (5 to 30%), clamp
tonnage (up to 40%), reduce or eliminate stress
and warping, as well as sink marks and will
as reduce or eliminate hold time resulting
in faster cycles and sizable cost savings.
LIM Liquid Injection Molding
Liquid injection molding
is a thermoset process using two-part silicone
rubber material that is injected into a heated
mold. The material is dispensed from a pressurized
pumping unit controlled by the injection molding
machine. The dispensing unit has a separate
control that manages ratios of material and
Toyo offers LIM injection molding on all machines
("Si II", "H" and "TT"
Metal Injection Molding
parts (using Powderflow ™) can be
produced faster, less expensively and without
having organic vapors given off with polymer
based materials. Most importantly, processing
is comparable to traditional materials (range
180°F). Pellet feedstock materials
are available in a wide range of stainless,
nickel, and ceramic based materials. After
molding parts will go to staged sintering
of several hours, ending at around 1300°C,
depending on the particular feedstock.
Injection Molding Machine
Electric disc Replicator; The ST-50discII
incorporates the finest optical disc replication
technology available anywhere in the world.
Vibration of the machine is one-sixth of our
conventional models. With injection speeds
of 500mm second and extremely fast clamp,
this machine is the chose of CD-DVD manufactures
around the world.
Die Casting Machine
die casting machines are available in a wide
range of sizes (125 to 850 Tons).
[Super Slow Shot System]:This
system allows you to handle a wide range
of products, from pressure-tight to thin
wall and precision components.
[Vacuum Casting System]:With
the VCS system, a runner pin isolates the
cavities and air is then removed to secure
a high vacuum. This prevents blow holes and
flashing and allows metal to flow into deep
recesses of complicated cavities.
[Hot Sleeve System]: this collier,
developed by TOYO, maintains the temperature
about 400°C. Since the melt is kept hot
it flows easily into deep and complicated
cavities, ideal for thin-wall precision products.
