What isα-system

α-system is self-curing mold production system under normal temperature.
This system is established with our developed safety organic curing agent.
We can provide our several phenolic resins for stronger,
low odor and high quality cast.

Waterborne alkali phenolic resin is much safety product,
and various organic esters can cure it, with various curing time.
To use the feature, we develop α-system to control curing time of mold.
It is possible to use some organic esters as curing agent in one mold,
to adjust curing time each parts of mold.

We provide all necessity explanation of features of
our phenolic resins and curing agents fully,
in order to be used our products and system safety and exactly.
And we will support you totally,
including temperature auto-control equipment to control curing speed.

  • Workable with various types of sand like Silica sand ,special sand, ceramic sand, etc.
  • Better working circumstance, due to extremely lower odor,
    smoke and harmful gas, while molding, pounding and crushing.
  • Flexibility of mold brings decreasing problem of veining and hot tearing.
  • Higher heat strength is effective to prevent burning on and provides good casting surface compared with other self curing process.
  • Low viscosity then easy handling

Strength comparison with new sand

Strength comparison high ADV reclaimed sand

Mold strength is effected by the properties of sands and reclaimed condition.
AR-170 corresponds greatly with the properties of both new and reclaimed sand.
AR-170 can offer high quality mold with excellent casting products.
