Handles are very common in life. Today, Zhejiang Laidi Technology Co., Ltd. will introduce the classification of handles.
Plastic handle:
made of plastic as raw material, plastic is a synthetic polymer compound {polymer), also known as macromolecule or macromolecule (macromolecules), also commonly known as plastic (plastics) or resin (resin) ), you can freely change the body style. The plastic handle is produced by an injection molding machine. The mold is designed according to the shape requirements. The injection molding can also be matched with a combination of zinc alloy parts (production by die-casting machine). The appearance composition can be: spray paint, electroplating, paint, etc., a typical representative of domestic professional development of plastic handles There is Cangnan County Maoquan Bag Fittings Factory. (Noun note: injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes. It is divided into vertical, horizontal, and all-electric Type. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity.)
Hardware handle:
traditional hardware products, also called "small hardware". Refers to various metal devices manufactured by forging, rolling, cutting, and other physical processing of metals such as iron, steel, and aluminum. For example, hardware tools, hardware parts, daily-use hardware, construction hardware, and security products. Most small hardware products are not final consumer goods. (Hardware note: [hardware;five metals of gold,silver,copper,iron and tin] five kinds of metals. Gold, silver, copper, iron, and tin are later referred to as hardware products, and also refer to various metals in general.)
Wooden handle:
Wood is the most of the hard fibrous material that makes up the stems and branches of trees or shrubs under the bark. In plants, the cell wall components of different cells vary greatly, which is the result of various other substances infiltrated into the cell wall. Common substances are keratin, cork, wood, mineral and so on. Wood is hydrophilic, it has a great hardness, therefore, the lignified wall not only increases the mechanical strength, but also permeable to water.
Rope handle:
With people's pursuit of perfection in life and the rapid development of industry, the rope has been woven from the previous twisted strands into two strands, three strands, 8 strands, 16 strands, 24 strands, 32 strands, and 48 strands. , Making the surface texture of the rope more and more delicate and beautiful, it can be woven together in one or multiple colors regularly, the color is more impressive, the material is available, hemp, brown, polypropylene yarn, polyester yarn, cotton yarn, nylon yarn 8 and other fibers or metal woven , Life can be seen everywhere.
Leather is animal skin that has been denatured and is not perishable, which is obtained through physical and chemical processing such as dehairing and tanning. Leather is tightly woven from natural protein fibers in a three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable.
Alloy handle:
common in zinc alloy handle, alloy handle is a substance with metallic characteristics synthesized by a certain method from two or more metals and non-metals. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-element alloys. China is one of the earliest countries in the world to research and produce alloys. In the Shang Dynasty (more than 3000 years ago), the bronze (copper-tin alloy) process was very developed; about the 6th century BC (late Spring and Autumn period), it was forged (remained) After heat treatment) a sharp sword (steel product).
