radiator cap

processing technology

Processing and assembly

overview

NIPPA is the leading company of
radiator caps for its wide range of
size,material, and pressure options.
Superior technology of caps is
fostered with our decades of
experience and knowledge.
Our caps are jointly developed and consistently
fabricated from its components to
sub-assembling. We have more than
70% share of the domestic and 20%
share of the international radiator
cap market.

terminal Sub-Assembly

processing technology

Ikki Tsuukan as directly press and
molding

overview

Our originally developed in-line
system, "ikki tsuukan," achieves
high efficient fabrication of terminal
sub-assembly. The connected
facilities automatically stamp,
transfer, and insert mold the
components. NIPPA's terminal
sub-assemblies ensure high
performance and durability.

 

Frame Assy

processing technology

Variable thickness precision forging press and welding

overview

The frame used to be fabricated with
cold forging and cut process.
However, with our patent method,
stamping is adopted to the entire
process, and it allows remarkable
cost reduction. Stamping enables to
flexibly thinned down and thicken the
material from 25% to 192%.
The entire processes from stamping
to welding are consistently handled
by our company.

Bobbin

processing technology

Insert molding

overview

From stamping to insert molding,
NIPPA entirely deals with the
processes. Refined striations of the
wiring area enables to coil efficiently
for higher performance.

Core Stationary

processing technology

Variable thickness precision forging
press

overview

With our leading technology,
core stationary is fabricated with
material flexibly thinned down and
thicken from t2.9 to t3.34 by
stamping process. The tolerance is
approximately 115%. This patent
obtained method allows high yield
rate.
