Professional Manufacturer of Quartz Crystal Sensors

Piezo Parts Co., Ltd

Piezo Parts Co.,Ltd. is a professional manufacturer of quartz crystal sensor.

The quartz crystal sensor measures frequency to high precision realized
by the inverse piezoelectric effect.
Crystal oscillators are used in quartz watches,
wireless communications, computers and many other uses.
And quartz crystal sensors will be used as one principal part of the oscillators.

Our main business is as the professional manufacturer
to produce the quartz crystal sensors which are the very important parts
in the optical and electronics industry nowadays.

The quartz crystal sensor’s usage has been expanding in more methods
due to the related products’ process has become complicated in these days.
Thus, the quartz crystal sensors need to be customized but still keep the stability.

In fact, we will make our best efforts to meet our customers’ expectations
We also have a business for undertaking to re-fabricate our used
quartz crystal sensors as good as new; therefore, we may contribute
to the cost reduction, the energy saving and the environmental protection.

Our products have been used not only domestically, to internationally!

QCM Sensor

When material adheres to the electrode surface on QCM sensor,
the resonant frequency reduces against to the material mass.

In other words, QCM sensor is eligible
for sensing nano-gram of mass
and consequently become a great function
of mass measurement in nano-unit range.

QCM sensor has their possibility as bio-sensor, odor-sensor
or hazardous gas detecting sensor
and can be useful tool in medical or bio-technological industries
for their wide usage.

We are specialized in this business since 1990 in Japan;
hence, we keep our products high in quality, accuracy and stability
with our technique which have been cultivated throughout history.

Our Goal and Effort

Besides the film thickness monitor crystal,
we have been putting effort on our QCM products.
We are also focusing on new development for QCM application expansion.

We have been working on to improve our products
with our own fabricating method,
and also putting more effort on quality control and inspection.
Thus, we can offer our products in high and stable quality.

Fortunately, we receive satisfaction voice from our customers such as
“Your products have higher yield rate!”
And they keep purchasing our products.

Our customer’s pleasure lead to our greatest pleasure.
We continuously devote ourselves
to offer reliability and pleasure to our customers.

Not only improving our current products by controlling
under strict management and inspection. As our new business activity,
we have been also working on new development on QCM application
to be used in technological and medical filed.

Furthermore, we have been expanding our business overseas
to receive cooperation globally.
Our goal is to contribute to further development for better future.
