At DELTA TOOLING, we have a consistent
operation from layout to fabrication for a variety of stamping dies used for
many different processes.
We develop high-quality, highly efficient production dies, including
progressive dies which require an advanced process design and processing
techniques by determining the best process from product’s layouts.
In addition, we develop and manufacture fine blanking dies and we offer them
with a great confidence for its highest quality in this industry.

Fine blanking manufacturing
technology enables the stamping of very precise, complex three-dimensional
products in one shot, and DELTA TOOLING offers a superior product line in this
area.
|
|
 |
| Our dies have a cross-section
equivalent to dies processed by machine without secondary finishing processes
such as cutting and grinding, which are required to traditional press work.
Products manufactured by these precise dies combining complex processes such as
bending, collapsing, and squeezing realize high quality in areas such as
dimensional precision, contour, and stability. |

 We succeeded in our efforts to use
stamping processes to mass-produce a helical gear, using a FB process; this was
regarded as impossible due to the accuracy required by gear parts, and also due
to surface roughness. We achieved a material thickness of 4 mm and a 14-degree
angle of torsion. |

 With our winning technology, we have made it
possible to manufacture "internal gears", internal recliner parts for
automotive seats by FB compound manufacturing processes, which is the first in
the industry.

 Scaling
up the gear |
Precision parts are made possible with the three-step compound process with
only microscopic shear drop in the teeth area, 0.38 module and R=0.168 at the
tips of the gear teeth. |

We handle many types of dies from
large, PRG moldings for automotive parts to precision PRG molding for
electrical components.
Progressive dies, also known as multiple-stage dies: at DELTA TOOLING, we are
in full command of the know-how required in the process design of each
manufacturing stage, designing the required progression of processes into one
structure for optimum productivity. In each process, products progress through
the next stage of the process, and then are completed after several shots.

Transfer dies are also called
"compounding" type dies.
They are dies with a construction in which the outer shape is stamped out and
then other various manufacturing processes such as squeezing, bending, and
stamping out, are implemented and enables us to combine processes and create a
complex product in one shot.
At DELTA TOOLING, we are striving to utilize the advantages of molding
technology to gain optimum yield ratio of manufacturing materials, reducing the
number of processes required for manufacturing.

We are performing squeeze-molding processes with a stepped and corner squeeze
of 11-degrees for motor parts' cases.
