Project stories
Here are the few examples of how we have managed to solve customer's requests.
Solutions can be categorized as the following three elements:
Cost reduction
Delivery time reduced by switching away from cutting work!
Customer’s request
Is there some way to solve this?
Our solution
Switch from out-sourced cutting ⇒ in-house threading!
Product features
The retaining work necessary for insert resin molding can be achieved by threading.
Matching the best elements from copper and iron!
Customer’s request
Our solution
We achieved 50% cost reduction by switching to our cost-reducing material "FCS-500" while maintaining performance level as a bearing.
Product features
FCS-500, which is copper-coated iron powder, can achieve the same noise levels as copper materials.
Performance improvement
Oil leakage was eliminated, and long life was achieved!
Customer’s request
Our solution
Poreless finishing prevents oil leakage from the bearing! Long life was also achieved.
Product features
By sealing the outer circumference of the bushing, oil leakage was reduced, inner pressure was increased, and oil film strength was increased.
Improved slidability and durability with low-speed specs!
Customer’s request
Our solution
We used No1-HG, containing solid lubricant (carbon), and grease/oil to solve the problem.
Product features
Low-speed high-load spec requirements can be met using material containing solid lubricant (carbon) and super viscosity oil.
Graphite-rich material
Customer’s request
Our solution
By increasing the graphite (a solid lubricant) content, slidability can be improved even in conditions where oil film formation is difficult.
Product features
Sliding is possible in a state close to dry metal.
Noise reduction
This is a new lubrication method that does not use oil, and it can also be used in very low temperatures!
Customer’s request
Our solution
Through lubrication using carbon fibers, we obtained lubricating ability even in low temperatures.
Product features
In a low-temperature environment, the viscosity of oil increases and its fluidity is also poor, making contact between the shaft and bearing easy to occur. By using carbon fiber in the role of cushioning/solid lubricant on the shaft and bearing surface, metal contact between the shaft and bearing when the motor starts can be prevented and noise can be reduced.
A major reduction of noise in a low-temperature environment!
Customer’s request
Is there some way to solve this?
Our solution
By using LF metal with a film coating on the surface, we achieved noise reduction.
Product features
The LF metal creates an effective resin by combining fluorine and metal and reduces the friction coefficient. It not only reduces noise but also helps improve abrasion resistance.
Oil-rich material
Customer’s request
Our solution
By increasing oil film strength and making the boundary lubrication (the sliding between metals) more similar to fluid lubrication, we succeeded in reducing noise.
Product features
Besides noise reduction, this is effective for low-voltage spec fan motors in the areas of sliding loss reduction in low friction, prolonging life span, and so on.
Products' Application
Heiwa Sangyo’s technology is used in offices, at home, and in various other places.
