O-RING
O-RING, our leader product, is used for various purpose, like parts for machines, industrial uses, sealing agent in construction site. It is ofcource our leading product.
O-RING needs high-degree of precision so that prevent liquids and/or gases into machines or any other usages.
Our products quality have been highly evaluated not only in Japan but also overseas.
We can also create in other colors, materials, sizes, hardness according to your purpose.
LARGE-DIAMETER JOINTED O-RING
JOINTED O-RING is the way how to create arbitrary-sized O-ring immediately.
Previously, non-standard O-ring was made by rubber string with adhesive. But in this way, such O-ring didn't have enough strength, oil proofness, chemical proofness, and some needed durability.
Our JOINTED O-RING is made by vulcanizing-pressed rubber as same as standard rubber products. Therefore, no adhesive used and it has enough strength.
This JOINTED O-RING technology enable us to create non-JIS standard o-ring without dedicated metal mold. In this way, it is possible to make large-size O-ring in shorter period and lower prices than previous.
Further more, such JOINTED O-RING is made in dedicated facilities for joint-mold so that it has high-precision in size and shape.
MATERIALS
| NAME | DESCRIPTION | USAGE |
|---|---|---|
| Natural rubber | It is most rubber-ness elasticity rubber. Has good mechanical property like abrasion-resistant. | Tires for automobile, especially for large vehicle and industrial tractors. Footwears, Hoses, Belts, Air spring and so on. |
| Synthetic rubber | Mostly same as natural rubber. Has good stability. | Tires for automobile, airplane. And almost usage as same as natural rubber. |
| Styrene rubber | Has higher abrasion-resistant and aging-resistant than natural rubber. Insulated from swings in price. | Tires for automobile, Footwears, Rubber fabric, Sports uses, Floor tiles, Parts for battery, cases, belts, and any other general/industrial rubber products. |
| Butadiene rubber | Has better elasticity and abrasion-resistant than natural rubber. | Tires for automobile and airplane, Footwear, Antivibration rubber, Huller, Belts, Hoses, and any other industrial rubber. Sometimes used as plastic modifier. |
| Chloroprene rubber | Has weather-resistant, ozone-resistant, heat-resistant, chemical-resistant. Almost averaged specification. | Wire covering, Conveyor belt, Antivibration rubber, Sash packing, Adhesive, Rubber fabric, and any other industrial items. Also used for paint. |
| Butyl rubber | Has weather-resistant, ozone-resistant, and resist permeability to gas. Moreover, can resist polar-solvent. | Inner-tube of automobile tire, Roofing, Curing bag, Wire covering, Sash packing, Steam hose, Heat-resistant conveyor belt. |
| Nytril rubber | Has good oil proofness, abrasion-resistant, aging-resistant. | Oil sealing, Gasket, Oil proof hose, Conveyor belt, Printing roller, Spinning roll, and any other oil proof rubber product. |
| Ethylene-propylene rubber | Has aging-resistant, ozone-resistant, polar-solvent proofness, good electrical property, and chemically stability. | Insulation cover, Weather strip for automobile, Sash packing, Steam hose, Conveyor belt. |
| Acrylic rubber | Has good oil-proofness in high temperature. | Packing and sealing for automobile transmission, crankshaft, valve, oil deflector etc. |
| Urethan rubber | Has especially good mechanical strength. | Industrial roll, Solid tire, Belt, High-pressure packing, Coupling, Die pad, and anything exposed to high-pressure. |
| Silicon rubber | Has highly heat or cold resistant, good oil-proofness. | Packing, Gasket, Oil sealing, Industrial roll, Heat/cold shield for antivibration rubber, Insulator, and medical uses. Also used for sealant and potting. |
| Fluoro rubber | Has the best heat-resistant and chemical proofness in rubber materials. | Packing for misiles and rockets, Packing, gasket, diaphragm, Tank lining, hose, pump for chemical factory, and any other rubber product with especially good heat-resistant, oil-proofness, chemical-proofness. |
| Perfluoro rubber | Has the best inactiveness in fluoro rubber. Has, better oil-proofness, chemical-proofness, polar-solvent proofness than ordinary fluoro rubber. | Physics and chemistry pump, Packing and oil sealing for paint/print machine. Also used in chemical factory, semiconductor factory. |
PACKING, GASKET, OTHER INDUSTRIAL PARTS
We select items as per your planning drawing, designated sample, and any using environments. We also can propose selection of material and shape of product. Experience our every-step proposal service.
Please ask anything about rubber product to experienced staff.
INSERT PARTS
We can build rubber parts into metal product like stainless steel, alminium, cupper, blass. Also plastic, fabric, and any other materials.
EXTRUSION MOLDED SILICONE
Our extrusion molded silicone product is made from Polymeric silicone. It has very low-toxicity, good heat/cold resistant, aging-resistant, weather-resistant. Good for electronic device and lightings.
