Casting capabilities include:Investment casting,Die casting,Sand casting,Gravity casting,Low-pressure casting,Prototype casting. Most common usage of the casting is the die casting and sand casting, but the sand casthing whose best advantages is the cheaper tooling cost.
Die casting is the most widely used method, suitable for the manufacturing needs of high-precision products. It is widely used in complex structural products and housings with internal cavities, such as engines and gearboxes.
What is the Die casting?
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

Gravity casting pours molten aluminum or copper alloys into permanent steel or cast iron molds without external pressure. Slower than pressure die casting, but preferred for thick-walled parts, heat-treatable aluminum, and castings where porosity control matters. Ideal for low to medium volumes.
Hot chamber machines keep zinc and magnesium alloys molten inside the machine, pushing metal into the die through a gooseneck at cycle times near 20 seconds. Best for zinc Zamak parts and small magnesium components up to 2 kg. We run hot chamber presses from 80 to 400 tons.
Cold chamber presses handle aluminum, brass, and higher-temperature alloys that would corrode a hot chamber gooseneck. Metal is ladled into a cold shot sleeve, then forced into the die at injection pressures of 70 to 175 MPa. Standard tonnage range 250 to 3,000 tons. Required for all aluminum die casting.
In-house mold shop designs and builds dies from H13 and SKD61 tool steel. Tooling prices from $8,000 for simple single-cavity zinc dies to $80,000+ for complex multi-slide aluminum tools. Expected tool life: 100,000 shots for aluminum and up to 1,000,000 shots for zinc
CNC milling and turning add threads, bore holes, and tight-tolerance features that cannot be cast directly. Tolerances to ±0.02 mm on machined surfaces. Integrated machining keeps the part on the same quality system from casting through final inspection.
Powder coating, anodizing (Type II and Type III), chromate conversion, wet paint, and electroplating applied in-house. Shot blasting and vibratory deburring are standard. Salt spray, adhesion, and thickness testing included with plated orders.
