Molten metal molded into consistent shapes at a friendlier price.
What it is
Die casting is a process where molten metal is forced under high pressure into a hardened steel mold, called a die. Once it cools, the part is released and usually finished. Zinc alloys and Aluminum are common choices. Because one die can produce many identical parts, die casting suits larger production runs and complex shapes. The alloy and finishing depend on the maker.
How it feels in your EDC
Die-cast pieces can feel solid and substantial, especially in zinc alloys, and the process makes approachable prices possible. Compared with CNC machining from solid stock, die-cast parts may show softer edges and less crisp detail, and some can contain tiny internal pores. Quality varies widely, and good finishing makes a big difference.
Care & aging
Many die-cast parts are plated or coated, so care mostly depends on that surface. Over time, edges and high spots may wear through the coating, revealing the base metal beneath. Wipe it with a soft cloth, keep it dry, and avoid abrasive polishes or harsh chemicals that can damage the finish.
是什么
压铸（Die casting）是在高压下把熔融金属注入淬硬的钢制模具（称为压铸模）。冷却后取出零件，通常再做表面处理。锌合金和铝（Aluminum）是常见选择。由于一套模具可以生产大量相同零件，压铸适合较大批量和复杂造型。合金和表面处理取决于品牌。
上手感受
压铸作品可能手感扎实有分量，锌合金尤其如此，这种工艺也让亲民的价格成为可能。与从实心原料 CNC 加工相比，压铸零件的边缘可能较圆钝、细节不够锐利，部分还可能含有细小的内部气孔。品质差异很大，好的表面处理影响很大。
保养与老化
很多压铸件有电镀或涂层，所以保养主要取决于这层表面。时间久了，边缘和凸起处可能磨穿涂层，露出底下的金属。用软布擦拭，保持干燥，避免会损伤表面的研磨抛光剂和强化学品。
