Corporate ProfileAlways aiming for the bestWe aim to leverage our unique technologies
to be your best partner in the ﬁne ceramics industry.
We provide products to support your developmentfrom a global perspective.
Tokai Konetsu Kogyo has continued to operate through the changing times with a focus on heating elements,
industrial furnaces and heating equipment while also developing new products to open new doors. The ﬁelds that
we serve have also changed signiﬁcantly according to the changes in our lifestyles. At present, businesses musttake action to protect the global environment. This has made it diﬃcult to contribute to the future society without
breaking away from the conventional corporate management and taking a new perspective.
As a pioneer in the ﬁeld of high-temperature applications, we have built a track record in a wide range ofindustries though many years of operation. We are expanding the technologies we have cultivated to the ﬁelds ofenergy, environmental conservation and next-generation communications. We will celebrate our 100th
anniversary in 2036. Instead of resting on our laurels, we will work to lay new foundations with the belief that weshould pass down the technologies that we have cultivated, the trust we have earned from our customers and thesingle-minded commitment of our people to people over the next 100 years.
While initiatives to build a sustainable society are becoming important criteria in the evaluation of companies,
Tokai Konetsu Kogyo Group, a member of the Tokai Carbon Group, will take on challenges bravely and promptly
to respond to major changes in society and cater society's needs to continue to contribute to society. We lookforward to your continued support of Tokai Konetsu Kogyo, which continues to work to achieve major goals.

Philosophy
Supported by the trust of our customers, employees and society, and acting incompliance with our guiding principles of fair activities, harmony with theenvironment, and internationality, we will fully leverage our management
resources to offer optimal products and contribute to the development of society.

Posture & Vision
Challenge
We continue to leverage the technologies that we have cultivated to enter new ﬁelds. We also takeon challenges to develop advanced products instead of only manufacturing the same products all thetime. These challenges include the development of environmentally friendly products, including
products with high energy efﬁciency and recyclable products.

Diversity
We aim to develop an open corporate culture where employees are free to express their opinions. By
applying various perspectives and ways of thinking, we will develop the diversity of the company asa leading manufacturer of industrial furnaces, heating equipment and heating elements.

Reliability
We believe that we have earned a great deal of trust thanks to the experience and knowledge wehave acquired over many years of devotion to the ﬁeld of high-temperature applications. We are also
striving to be a company that gains reliability by advancing technologies.

EREMA heating elements
Composed of high-purity silicon carbide (SiC), EREMA heating elements are the ﬁrst siliconcarbide heating elements marketed in Japan. Since we made them commercially available in
1927, we have been committed to research based on our wealth of experience, striving toimprove their quality using our unique development technologies and other internal andexternal technologies. Now, we have been highly regarded for our production scale, which is
the largest in the industry and our products, which are of the highest quality in the ﬁeld.

Industrial furnaces and heating equipment
Industrial furnaces and heating equipment, which are also referred as electric furnaces or combustion
furnaces, are used for heating, sintering, dissolving and thermally treating ceramics, electroniccomponents, metals, glass, powders and other materials at speciﬁc temperatures. We have anextensive track record in the design and manufacturing of industrial furnaces and heating equipment,
etc. for heat treatment. We also have advanced composite technologies as a comprehensive
manufacturer of heating elements and refractories, which are necessary for industrial furnaces andheating equipment. With our track record and these technologies, we supply products ranging fromsmall testing furnaces to large industrial furnaces for customers in every ﬁeld.

5

EREMA ceramic resistors
Since 1961, we have been involved in the manufacturing and sale of ceramic resistors, contributing
to the improvement of technologies and performance in a wide range of ﬁelds including electric
power, communications and healthcare. EREMA resistors are ceramic resistors sintered at a hightemperature. They are therefore optimal for circuits which must be highly reliable under extreme
conditions.

RECRYTERECRYTE is the trade name of our SiC ceramic
high-temperature materials. Our lineup includes
recrystallized, reaction-sintered and pressureless-sintered materials designed to be usedsafely in high temperature environments.

6Shipping inspection process
̶ T o ma inta in the high q u a l ity of ou r pr od u cts ̶All EREMA heating elements are inspected before shipping.
In addition, we dispatch our engineers to customersʼ sites where our industrial furnaces
or heating equipment is installed. They work on-site until it is conﬁrmed that the installedfurnace or equipment is operational. We are continuing to work steadily to earn the trustof our customers.
