Low-cost iron insert and outsert colors as a substitute for brass.
By replacing the brass color used in insert molded products, the cost of the color can be reduced by 50-60%.
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!
basic information
Measures to achieve the material change from brass to iron - Surface treatment (plating) to ensure heat resistance (thermal conductivity) and compatibility with insert molding - Ensuring breakage and tensile strength through knurling on the outer circumference - Changing to iron (SWCH) and switching to forging
Price information
It varies depending on conditions such as type and quantity, but significant cost reductions can be achieved with brass-colored products.
