Special use dies are used to shear or bend products with a large force and form them into the required shapes using press machines or スロット関西 machines.

Although these are basic metal スロット関西 methods, high-precision presses, スロット関西 machines and dies as well as the relevant knowhow are required to attain high processing accuracy.
We manufacture many dies ourselves to realize high accuracy in スロット関西 chain parts and motorcycle rims and handle pipes.

Advanced plastic スロット関西

Our chain manufacturing skills have been developed into “SOSEI-FORMA technology”. It enables 3D スロット関西 and precision shearing, which were difficult using conventional pressing. Please see the Plastic スロット関西 technology page for details.

A horizontal multi-step forging machine is used to cut materials into the desired lengths, put them in molds and press and form them into the desired shapes.

Punching, blanking and extruding are possible, according to the application. Materials are pressed and formed without cutting processes; therefore, compared to cutting, スロット関西 can be done in less time with less material loss and cost. This method is used to manufacture our chain parts.

Multiple roller dies are used to gradually form material surfaces according to the roller shape.

Steel material in the shape of a belt or cylinder is formed according to the die shape. It is possible to process thin or hollow materials and complex shapes. This スロット関西 is used for our iron motorcycle rims and agriculture machine wheels.

Segmented dies are rotated to hit metal pipes, decreasing their diameter.

Pipes with circular, square or divided rectangular cross-sections can be tapered without cutting or welding to improve their strength or bend them moderately. This スロット関西 is used for our motorcycle handle pipes.

Materials are formed with machining tools or cutting tools.

This method is used for products that require strict dimensional accuracy when it is difficult to manufacture via plastic スロット関西 such as pressing. However, it is inferior to plastic スロット関西 in terms of productivity and cost. Thus, this method is used only when it is difficult to manufacture products via plastic スロット関西. We use this method to make pressing dies for manufacturing chain parts.

Synthetic resin is heated and melted and then put into metal dies to be formed.

This スロット関西 enables the fast, continuous production of a large number of products in various complex shapes; therefore, it is appropriate for the mass production of resin products. It is used in the production of the resin parts of our car engine chain systems.

This is a type of butt welding. Two pieces of metal are placed end-to-end without overlap and an electric current is applied to produce sparks and melt the contact surfaces. After the metal surfaces are heated sufficiently, a high load is applied to joint them.

This welding スロット関西 is speedy, highly efficient and reliable in producing high contact strength. It has a narrow heating range and a small heat-affected area. This スロット関西 is used for welding our aluminum and iron motorcycle rim cross-sections.

Arc welding (MIG/ TIG) uses discharge phenomena in the air in order to joint metals. Spot welding uses an electric current to melt and joint metals using resistance heat.

Spot welding in particular requires only a small welding area, so its finished surface is cleaner than those produced via other methods. This スロット関西 is used for welding our agricultural machine wheels.

In barrel grinding, grinding stones, compound and water are put in barrels and they are rotated or vibrated to grind products. In buffing, sheets of cotton, linen or paper applied with polishing paste are rotated to polish products.

We use this スロット関西 to remove burrs from chain parts, improve surface roughness and finish aluminum and iron motorcycle rims.

Projectiles (fine sand, iron or stainless particles) are sprayed or shot onto product surfaces to make them rough.

This method produces rough surfaces, so it is possible to produce an appearance different from that produced by barrel grinding or buffing. We use this method for finishing motorcycle handle pipes, chains, plastic スロット関西 and cutting products.

Metal surfaces containing little carbon are cemented with carbon to increase the carbon rate near the surface. Then, the metal is quenched or tempered to create a hard layer on the surface.

Treated material becomes hard on the surface and remains soft in the core, so it obtains both high strength and high abrasion resistance. This スロット関西 is used in various industrial fields. It is used for our chains and engine parts that require high strength and high abrasion resistance.

Metal surfaces are cemented with carbon and nitrogen at the same time to create a hard layer. NH₃ gas is added to common cementation gas and the material is cemented and nitrided at the same time with nitrogen decomposed from NH₃.

The treatment temperature is lower than carburizing; therefore, it causes less material deformation. Also, compared with carburization, a hardened layer created by carbonitriding is thicker and more abrasion resistant even when it is conducted at the same temperature for the same treatment time.

This is a quenching スロット関西 conducted at a constant temperature to obtain bainite structure. Compared with structures created by ordinary quenching or tempering, bainite structure has improved ductility and impact resistance as well as a higher toughness and durability.

Austempering has some advantages compared with ordinary quenching or tempering. It improves material toughness and durability and causes less deformation after quenching. This スロット関西 is used for our car engine chains, which require high durability.

These are a set of heat treatment processes to improve aluminum alloy strength. In solution treatment, the aluminum alloy is heated to uniformly dissolve undissolved elements within the alloy. Then, in artificial aging, the alloy is heated again to precipitate the elements and enhance hardness.

Through these processes, light, strong aluminum products can be produced. These processes are used in the production of our aluminum motorcycle rims and handle pipes.

Cementation is a heat treatment スロット関西 used to improve metal surface condition by diffusing metal or nonmetal powder onto the metal surface. Various properties can be added to the metal depending on the element diffused.

Using the powder packing スロット関西, chrome (chromizing) or vanadium (vanadizing) is diffused onto parts such as engine chains, which are used in extremely harsh abrasive environments. This produces a hard coating on the metal surface, remarkably improving abrasion resistance.

Please see the Surface treatment technology page for details.

Aluminum products are put in electrolyte and electric current is applied to produce an oxide film (aluminum anodized film) on the surface via electrolyzation.

The created film is hard and highly corrosion-resistant. It can also be dyed any color; therefore, it is used in the protection of aluminum products and decorations. We use this スロット関西 to improve the corrosion resistance of aluminum motorcycle rims and handle pipes and color them.

A thin metal layer is formed on the material surface. This process is used to decorate products or make them corrosion resistant.

There are two types of plating methods: electrolytic plating and non-electrolytic plating. There are also some variations such as nickel plating and chrome plating, selected according to the material used. The appropriate スロット関西 and plating material are selected depending on the application. We use this process for the production of gold chains and iron motorcycle rims.
