Plastic handle: made of plastic, Plastic is a synthetic polymer compound {polymer, which can also be called polymer or macromolecule. It is also commonly known as plastic or resin. It can change the shape and style freely. Plastic handles are produced by injection molding machines. The molds are designed according to the shape requirements. They can be molded at one time. They can also be equipped with zinc alloy parts (produced by diecasting machines). The appearance composition can be: painting, electroplating, painting, etc. hardware handles: traditional hardware products, also known as “hardware” 。 It refers to various metal devices made of iron, steel, aluminum and other metals through forging, calendering, cutting, and other physical processing. For example, hardware tools, hardware parts, daily hardware, construction hardware and security supplies.
Wooden handle: wood is most of the hard fibrous material under the bark of the stems and branches of trees or shrubs. In plants, the cell wall components of different cells vary greatly, which is the result of the infiltration of other substances into the cell wall. Common substances include cutin, cork, wood, mineral, etc. Wood is hydrophilic and has great hardness. Therefore, the lignified wall not only increases the mechanical strength, but also can be permeable.
Alloy handle: it is common in zinc alloy handle. Alloy handle is a material with metal characteristics synthesized by two or more metals and nonmetals through certain methods. It is generally obtained by melting into uniform liquid and solidification. According to the number of constituent elements, it can be divided into binary alloy, ternary alloy and multicomponent alloy. China is one of the earliest countries in the world to study and produce alloys, and the bronze technology was very developed in the Shang Dynasty; Sharp swords were forged in the late spring and Autumn period around the 6th century BC.
