Cast Iron & Steel Sand Casting Foundry Sand casting uses green sand (moist sand) or dry sand to form the molding systems. The green sand casting is the oldest casting process used in history, while the dry sand casting could be divided into lost foam casting and vacuum casting. When making the mold,

Finding a reliable supplier for cast metal components is not only a matter of price, but a long-term decision that affects product performance, delivery stability, and overall project risk. In today’s global manufacturing environment, buyers must evaluate suppliers beyond simple quotations and focus

As manufacturing enters a more rational growth cycle, the global casting industry in 2026 is undergoing a clear transformation. Instead of expanding capacity blindly, foundries are redefining competitiveness through stability, material control, and application-oriented production. This shift is resh

Selecting a casting material is no longer a matter of simply picking a metal—it defines the performance, durability, and efficiency of every component. At Densen, we approach material selection as a design decision, matching properties to specific operational needs.Iron-Based MaterialsIron castings

Machining is no longer defined simply by removing material; it has evolved into a precision-driven discipline built around process stability and predictability. In modern manufacturing, precision machining services focus on how cutting behavior, tool interaction, and material response work together

In our foundry, we focus on gravity casting, a method that leverages gravity to fill molds with molten metal, providing reliable dimensional stability and consistent material properties. Unlike high-pressure methods, this process emphasizes simplicity, structural integrity, and adaptability for a wi

Sodium silicate casting is recognized as a practical metal forming method for applications where structural reliability and cost efficiency must remain balanced. Instead of pursuing ultra-fine surface finishes, this process prioritizes mold strength, dimensional stability, and adaptability across a

In modern precision manufacturing, silica sol casting has become a preferred solution for metal parts that demand fine detail, dimensional stability, and surface consistency. We view this process not as a variation of traditional investment casting, but as a refinement driven by tighter technical ex

When we work with metal stamping, our attention stays on how the material behaves at each forming step. Instead of chasing speed, we study how sheets react to pressure, direction changes, and tool contact during stamping cycles. This mindset helps us keep part behavior predictable across repeated ru

Recently, we took a fresh look at how we handle lost foam casting, not by adding new equipment, but by adjusting the steps that actually influence the final part. In our daily production, we noticed that small variations in foam pattern density, drying conditions, and sand compaction could create bi
