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!

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.

Are you considering reducing costs associated with post-processing of metal cast parts by using zinc die casting to eliminate machining? Zinc die casting has a higher specific gravity compared to aluminum, resulting in a relatively increased weight. However, it has good fluidity during casting, allowing for excellent flow within the mold, enabling thin-walled designs and high-precision casting at a level of 3/100. This means that high-precision castings can be produced that do not require post-processing once removed from the mold. As a result, by leveraging the precision of casting, it becomes possible to significantly reduce costs by eliminating machining for products that previously required post-processing in aluminum die casting. Additionally, in some cases, such as sensor covers and other sheet metal products, eliminating welds has led to significant cost reductions depending on the size. Using zinc materials with lubricating properties for gears and sliding parts also allows for cost reductions through VAVE. 【Features】 ■ Good fluidity during casting, enabling precision casting ■ Proven applications in gear parts for camera and lens autofocus, movable parts in semiconductor mounting machines, and automotive components (such as seats) ■ Post-processing-free designs utilizing approximately 3/100 precision for palm-sized components ■ Safe alloys used in children's toy cars

By converting small sheet metal parts with welded joints to zinc die casting, it may be possible to eliminate welding! Zinc die casting has a higher specific gravity compared to aluminum, resulting in a relatively increased weight. However, it has good fluidity during casting, and the flowability within the mold during casting is also excellent, allowing for thin-walled designs and high-precision casting at a level of 3/100. This enables high-precision casting that does not require post-processing once removed from the mold. Even parts that are welded from sheet metal, such as sensor covers made of sheet metal, may become more cost-effective overall by switching to zinc die casting, despite the mold costs. Additionally, since it is die casting, it allows for integration of other parts, enabling innovative designs for component unification. **Features** - Excellent fluidity during casting, enabling precision casting - Proven applications in gear parts for camera and lens autofocus, movable parts for semiconductor mounting machines, and in automobiles (such as seats) - Post-processing free with a precision of about 3/100 for palm-sized parts - A safe alloy used in children's toy cars

The feature is that "we achieve a beautifully mirror-like shear surface with a standard press." Typically, when punching with a press, a fracture surface occurs, and especially when creating precision or mechanical parts from difficult-to-machine materials like SCM or S45C, additional processing to handle the fracture surface created during punching was necessary. However, it has become possible to manufacture thick press parts with shear surfaces comparable to fine blanking, and with a mirror-like finish and smoothness, using a standard servo press. In particular, for thick press parts where additional processing was required to achieve cutting surface precision, there is a possibility of eliminating finishing processes! By utilizing this precision pressing technology for thick press parts, we have achieved high cost competitiveness, including mold costs and processing costs.
