The gravity casting is one type of permanent mold casting. The gravity
casting main advantages are the reusable mold, good surface finish, good
dimensional accuracy, and high production rates.

The die casting is suitable for applications that require good surface
finish and dimensional consistency. The main die casting alloys are:
zinc, aluminium, copper, magnesium, lead, and tin etc.

Sand casting also called sand mold casting, it's used to produce a wide
variety of metal components with complex geometries. These metal parts
can vary greatly in size and weight, ranging from a couple ounces to
several tons. The small sand cast parts include as gears, pulleys,
crankshafts etc.

For the past 10 years, we have successfully exported many metal
casting parts to worlds. We provide a variety of metal casting
processes, including: sand casting, die casting, low pressure casting,
gravity casting (permanent mold casting), investment casting, and
precision casting.

Machining
Machining is manufacturing process that involves removing materials
using cutting tools for getting rid of the unwanted materials from some
workpiece and converting it into the shape you desire. A large piece of
stock is used for cutting the workpiece.
