What exactly is Sourwood? Sourwood, also referred to as "Sun Branch" or "Purple," primarily grows in tropical and subtropical climates. It’s commonly cultivated in countries like India, Thailand, Myanmar, Vietnam, Cambodia, Laos, Brazil, and Madagascar. In China, specific regions such as Xishuangbanna and parts of Yunnan produce a variation of this tree, which is often called "hornbeam." The sapwood of this tree varies from yellowish-white to yellow-brown, while the heartwood exhibits rich hues ranging from orange to light reddish-brown, reddish-brown, purple-red, and even dark brown. There's often an uneven distribution of colors with noticeable dark streaks. Growth rings are either faint or somewhat visible, and there may be loose or semi-annular pores. The tree contains single tube holes, though some may have larger diameters or groups of smaller tubes with dark resin, sediment, or invaders. The axial thin-walled tissues feature wing-like structures, ribbon-like forms, loop bundles, and wheel boundaries. The wood grain is incredibly fine, with an average tube hole chord diameter not exceeding 200 micrometers. The diameter markings are subtle, and string masks often display wavy patterns. The wood itself is glossy and emits a sour or slightly floral scent depending on the specimen. Its texture ranges from oblique to interlocked, providing excellent durability and resistance against decay. The material is dense and heavy, boasting high strength. At 12% moisture content, its air-dry density exceeds 0.85 g/cm³, meaning it typically sinks in water. Key Features of Rosewood Rosewood is renowned as the primary material used for crafting Qing Dynasty mahogany furniture. Furniture made from sourwood remains in excellent condition even after centuries, requiring minimal restoration. A simple application of enamel paint can rejuvenate its appearance, highlighting the exceptional quality of the wood. This material has long drawn global admiration due to its striking colors, which range from deep red to lighter shades. Trees with more "fat" or resin tend to be of higher quality, featuring a finer grain, greater hardness, and the ability to sink in water. One of the most captivating aspects of rosewood is the presence of dark red or black streaks against a deep red background, creating a pattern that is both distinct and varied. Polished rosewood furniture shines brilliantly and maintains its luster over time, offering a refined elegance that is timeless. Beyond its aesthetic appeal, the wood's robust nature ensures longevity. In contemporary terms, it represents the epitome of true mahogany furniture.
Cold extrusion is a manufacturing process in which a metal or alloy is forced through a die to create a desired shape or form. This process is typically performed at room temperature, hence the name "cold" extrusion.

A cold extrusion Hydraulic Tool is a specialized tool used to perform cold extrusion processes. It typically consists of a hydraulic press or machine that applies high pressure to force the metal or alloy through the die. The tool may also include additional components such as a die holder, die set, and ejector system.
The hydraulic system of the tool provides the necessary force to deform the metal or alloy and shape it according to the die's specifications. The pressure is applied gradually and evenly to ensure a uniform extrusion without causing any damage to the material.
Cold extrusion hydraulic tools are commonly used in various industries such as automotive, aerospace, and construction. They are used to produce complex shapes and components with high precision and strength. Some examples of products made using cold extrusion include shafts, tubes, rods, and various structural components.
Overall, cold extrusion hydraulic tools are essential in the manufacturing process of many metal and alloy products, providing a cost-effective and efficient method of producing high-quality components.
