In die casting, liquid metal is injected into a steel mold under high pressure to create a pin. Once the mold cavities fill, the metal cools and solidifies into the intended shape before being removed. For intricate details and sharp lines, die striking is ideal. For 3D shapes and hollow features, choose die casting. 3D die casting is generally more cost-effective for large quantities, while die striking offers premium quality for a higher price point.Die-struck pins are more durable, especially for long-term wear.
