|
| ▶ Product Development Design |
|
Design drawings according to the product or
drawing requested by the customer. | |
|
| ▶ Mold making |
|
A mold for injection of the wax pattern is
manufactured in
consideration of the expected order quantity and
the like in accordance with the prepared drawings. | |
|
| ▶ Wax pattern production |
|
injecting a semi-solid wax into the mold to
mold the solid wax circle. | |
|
| ▶ Wax assembly |
|
A wax pattern projected by a mold is a step of
making a tree (mold) by assembling in the form
of a twig into a runner bath produced in advance. | |
|
| ▶ Coating(Molding) |
|
It is a very important process to repeatedly
apply the assembled mold with special ceramics
material several times and it is a molding operation
that takes a long time. This process is one of the
important processes that determine the quality of
precision castings. | |
|
| ▶ De waxing |
|
It is the process of removing the wax circle
inside by dissolving the wax in the coated cell. | |
|
| ▶ Cell firing |
|
Before injecting the molten material into the cell,
the wax remaining in the cell is completely removed,
and the cell is placed in a firing furnace and
sintered / preheated to improve the strength
and air permeability of the cell. | |
|
| ▶ Casting |
|
It is a process of injecting dissolved molten
material into a cell (mold), and it can be said that
it is a process in which the shape of a product
requested by a customer is produced. | |
|
| ▶ Absorption(cell removal) |
|
When the mold is completely cooled, it is not
necessary to use a ceramic mold attached to the
mold surface of the tree-like mold, so that it is a
process of separating by using a physical impact
such as a hammer. | |
|
| ▶ Excision |
|
Cutting various cutting equipment at the gate part
of the product attached at regular intervals at
regular intervals and performing the separation
process. | |
|
| ▶ Grinding |
|
This is the process of grinding / mapping the
residual gate, which is the injection port of the
product, through the sandbelt. | |
|
| ▶ Short and post processing |
|
|
Air shot, etc. Removal of sand buried in the casting
process After the series of finishing operations
such as surface modification, deformation
orrection, surface treatment, etc. of the casting
urface improvement, the desired precision casting
with added value is completed. | |
|
| ▶ Heat treatment |
|
It is a heat treatment process to increase the
mechanical properties of the product. | |
|
| ▶ Calibration and Inspection |
|
It is a final inspection process that confirms
whether the finished finishing precision casting
conforms to the various quality levels required by
the drawing, and if it is necessary to calibrate it,
it completes the complementary work and confirms
whether it is good or not. | |
|
| ▶ Packing and delivery |
|
The completed castings shall be packed and
packed according to the domestic packing export
packing in accordance with the customer's
requirements. |
