Problems solved by technology

[0004] (1) Due to the high price of metal materials and the high cost of raw materials for string bead heads, string products lack market competitiveness
[0005] (2) The use of metal materials to make string bead heads requires cutting tools for turning processing. Since the metal material is hard, cutting tools with higher hardness are required to complete the turning processing. The requirements for processing equipment are high, and the processing cost is also high.
[0006] (3) Due to the hard metal material, the tool is easy to wear during turning, and even damages the tool in serious cases, so the tool needs to be replaced frequentl

Example Embodiment

[0027] like figure 1 Shown is a string bead head 1 with the function of distinguishing the strings, the string bead head 1 is an I-shaped wheel structure, and the material of the string bead head 1 is a plastic mixture.

[0028] The plastic mixture is composed of plastic and color masterbatch, wherein the color masterbatch is red color masterbatch, and its weight ratio to plastic is 6:1000.

[0029] The above-mentioned color masterbatch can also use color masterbatches such as green, yellow, blue and other colors. The weight ratio of color masterbatch and plastic can be between 5 and 30:1000, such as 8:1000, 10: 1000, 12:1000, 15:1000, 20:1000, 25:1000, etc., the color masterbatch is selected from commercially available color masterbatch, and the plastic can be ABS or PC with a certain strength.

[0030] The colored string bead head of the present invention not only has the function of distinguishing the strings, but also has the function of permanent marking which never fade...

Abstract

The invention discloses a music string ball head with the function of differentiating music strings and a manufacturing process thereof. The music string ball head has an I-shaped wheel structure and is made of plastic mixture. The musical string ball head is made of plastics of various colors and has low cost, can be processed and molded conveniently, as well as has extremely good music string differentiating function. The invention also discloses the manufacturing process of the music string ball head, which comprises the following steps: (1) the molding step of the sectional material of the music string ball head: adopting an injection molding technology, taking the plastic mixture as the raw material and manufacturing the strip-shaped sectional material of the music string ball head; and (2) the processing and molding step of the music string ball head: turning and processing the obtained sectional material obtained from the step (1) and manufacturing the sectional material into the music string ball head.

Description

technical field [0001] The invention relates to a plastic string bead head with the function of distinguishing strings, and also relates to a preparation process of the string bead head. Background technique [0002] The bead head of the string is an indispensable object on the steel string. Its function is to be stuck on the bridge to fix one end of the string, and the other end is on the peg on the level. Because one end of the string is fixed on the bead head On the bridge, adjust the tension of the strings to achieve the sound required by the strings by rotating the aligned pegs. [0003] In the prior art, the string bead head is generally made of metal materials such as copper or iron, and the metal string bead head has the following defects: [0004] (1) Due to the high price of metal materials and the high cost of raw materials for string ball heads, string products lack market competitiveness. [0005] (2) The use of metal materials to make the string bead head req...
