We pursue the basic technology cultivated over many years in the field of adhesive coating. Begin with automobile interior parts, we provide a wide range of products to various industries such as mobile phones and digital cameras' electronic parts and housing-related parts. Hereafter, we will continue to grasp the world movements, environmental changes, and technological trends quickly. Further, we will promote and strengthen our development and proposal capabilities to provide products that match new needs.
"We are in the period where silence is required progressively in both automobiles and housing. Demand for sound absorbing and insulating materials is increasing. Many materials need to be considered for this development.
However, according to JIS standard, the measurement of sound absorption coefficient and transmission loss by the general reverberation room method requires large test sample of around 10m2.
We have installed sound absorption coefficient and transmission loss measurement equipment with 500mm x 500mm sound absorption coefficient and 600mm x 600mm transmission loss,
which is about 1/40 for an equipment that conforms to the JIS standard.
It enables a small amount of test sample measurement, so it is possible to perform comparative tests of more materials.
We can cooperate in the development of new sound absorbing and insulating materials."
"We have installed an automatic coating equipment by robot using hot melt-based water blocking and adhesive coating, mainly for automobile parts.
With this equipment, it is possible to apply hot melt-based water blocking materials and adhesives in stable even for complicated shapes."
"Thick urethane and other foam materials are soft and difficult to cut.
By using our vertical cutter equipment, it is possible to cut cleanly.
Processable size
・ Thickness: 2mm to 100mm
・ Width: 20mm to 1200mm
・ Length: 20mm to 2000mm"
"These are product examples of foam PE or PP made by punching into a washer shape. Available in various specifications such as hardness, color, adhesive processing on the back side or with tape.
Mass production will be done by press type, however if you need to consider in advance, we can also handle by cutting plotter. "
"Weight reduction is required to improve the fuel efficiency of automobiles.
We have installed foam hot melt coating equipment.
By filling with nitrogen gas, it is possible to apply coating while foaming hot melt.
Compared to conventional butyl-based sealing materials, the weight can be reduced approximately 40% and workability can be improved.
[Hot butyl (current product)]
Material: butyl rubber base
Sealing: possible
Required crimping power: high
Assembly workability: Re-peel (re-work) is not possible
Weight (specific gravity): 1.1
↓ Weight reduction to improve fuel efficiency ↓
[Foam hot melt]
Material: hot melt + nitrogen gas
Sealing: possible
Required crimping power: low
Assembling workability: Re-peelable (reworkable)
Weight (specific gravity): 0.62 ->Succeeded in weight reduction approximately 40%

"Acrylic foam tape is excellent by its high adhesive strength, heat resistance, weather resistance, and flexibility. It is used for automobiles and various parts fixing. However, it is also a fact that processing is difficult due to its characteristic.
We have a track record of processing various acrylic foam tapes such as VHB (3M) and HYPERJOINT(Nitto).
Please leave acrylic foam tape processing to us."
"By transfer method using a roll coater, it is possible to apply coating on acrylic adhesive. Focusing on sound absorbing materials, damping materials, and cushioning materials for automobile interior parts, adhesive processing of various materials is possible.
Both long products and flat plates can be used. In the case of long products, it is possible to winding after coating and cut to a fixed size.
Work size
Thickness: up to 70 mm
Width: up to 1250 mm
For long products
Maximum diameter: 1300 mm
Winding diameter after coating: 950 mm
Cutting size: 550 mm to 2100 mm"
"Product name: Spacer
