Japan Quality
Proprietary technology for producing high-quality rubber molded products.
Harigai Industry Co., Ltd.
About Us
Our company specializes in manufacturing functional rubber products, utilizing various rubber materials, primarily silicone rubber.
Using the latest vacuum molding press machines, we produce high-quality sealing rubber and a variety of molded products. We not only process standalone rubber products but also produce vulcanized bonded products with metals.
Since we design rubber material formulations and can create prototype molds in-house, we are actively accepting orders for not only mass production but also product development and prototype production.
Do you have any troubles like these?
✓Rubber in current use presents numerous quality issues.
✓A company able to stably supply desired rubber products is sought.
✓A contractor available for consultation from material selection onward is sought.
Let us handle it!
Our Strength
Proprietary technology has created a new type of rubber sheet with unprecedented materials
CFR（Carbon Fiber Rubber）
Patent acquisition: Patent No. 6531245
CFR（Carbon Fiber Rubber）
One of our flagship products is the "CFR" — a product that combines rubber and carbon fiber. Carbon fiber has traditionally been a difficult material to bond, but with our proprietary technology, we have succeeded in creating a strong bond.
The "CFR Sheet" is an innovative reinforced rubber sheet that leverages the high strength and lightweight properties of carbon fiber along with the elasticity and flexibility of rubber, offering features such as light weight, high strength, impact absorption, and flexibility.
This material is already being used in the sports industry and has been tested in disaster prevention products, automotive sectors such as tires, and in the energy field like wind power generation. It is also expected to be utilized as reinforcement material for hydrogen fuel tanks, which are anticipated to become more widespread in the future.

Message
The "CFR" is a completely new material like no other.
It combines the elasticity of rubber and the high strength of carbon fiber,
making it particularly excellent in shock resistance and energy absorption.
It can also be used in combination with CFRP and other materials.
