Under various environmental conditions where multiple deterioration factors such as severe wear, corrosion from chemicals and seawater, thermal effects, and cracking due to impact are compounded, polyurea exhibits its properties and continues to protect the substrate for an extended period. High-grade polyurea has long-term resistance to 50% sulfuric acid, protecting the substrate from corrosive factors (such as acids and alkalis). Additionally, in JIS standard paint wear tests, it shows a remarkable wear resistance with a coating loss of only 3 mg compared to other lining materials. Its high weather resistance also allows it to maintain stable strength outdoors for a long time. By applying polyurea coating to particularly deteriorated components such as bulldozer buckets, power shovel scoops, tractor tilling blades, and combine harvester cutting blades, a significant extension of their service life can be expected. In the case of snowplow shovels, polyurea coatings have demonstrated significant effectiveness in wear resistance and resistance to calcium chloride.

Four Strengths - Functionality equivalent to petroleum-based plastics - A first step towards reducing plastic usage - CO2 emission reduction effect - Low cost [Functionality equivalent to petroleum-based plastics] It has moldability, convenience, strength, and quality comparable to petroleum-derived plastics, offering similar functionality. [A first step towards reducing plastic usage] With a biomass content of 25%, it reduces the use of finite petroleum-derived plastics by 25%, serving as a first step towards environmental measures and reducing plastic usage. [CO2 emission reduction effect] In Japan, waste disposal is primarily through incineration, including plastics. Incineration results in CO2 emissions, which are a significant environmental issue. This cushioning material reduces CO2 emissions during combustion by approximately 25% compared to plastic (PP), as verified by CERI (Chemical Evaluation and Research Institute). The reduction effect is recognized, rather than just theoretical carbon neutrality. [Low cost] In terms of cost, it is about 1.5 times that of plastic (PP), making it cheaper than bioplastics.

If you are performing post-processing on aluminum die casting, it may be possible to achieve post-processing-free results with zinc die casting. Yashima Denso proposes "zinc" die casting. Zinc has a higher specific gravity compared to aluminum, but it has good fluidity and flowability within the mold during casting, allowing for the production of high-precision products at a level of 3/100. As a result, by utilizing the precision casting, we can contribute to significant cost reductions by eliminating post-processing for products that were previously processed after aluminum die casting! Using zinc materials with lubricating properties in gears and sliding parts also enables cost reductions through VAVE. 【Features】 ■ Good fluidity during casting, allowing for precision casting ■ Proven results in camera and lens parts, semiconductor mounting machines, and automotive applications (such as seats) ■ Post-processing-free products utilizing precision of about 3/100, roughly the size of a palm *For more details, please download the PDF or feel free to contact us.

Press processing involves placing a workpiece on a die and pressing it with a punch. In conventional press processing, a significant clearance (the gap between the die and the punch) is required, which can lead to the workpiece having many "dents" and "burrs." "Fine Blanking (FB) processing" is a method that applies pressure from both directions with minimal clearance. This results in a finish with fewer dents and burrs, eliminating the need for post-processing. Additionally, it allows for processing while maintaining the thickness of the material, greatly contributing to the reduction of raw material costs. 【Main Achievements】 ■ Automotive disc brakes ■ Automotive muffler flange components ■ Gear components for automobiles and motorcycles etc. *For more details, please download the PDF or feel free to contact us.

By converting brass-colored materials to iron, we have achieved a cost reduction of 50-60% while also enhancing the pull-out strength and break (twisting) torque to levels comparable to brass products. Brass inserts and outserts are expensive due to the high copper content in the brass material itself. However, brass has become the mainstream choice due to its good workability, which ensures heat resistance (thermal conductivity), break torque (twisting torque), and pull-out strength during press-fitting into resin (induction heating). By switching to iron, which is a cheaper material compared to brass, we have reduced the cost of the collar itself while still meeting the mechanical requirements of the insert collar and achieving ironization. There is also a proven track record of this in vehicle engine rooms!
