[Chinese Button Trading Network] The “Kong†button is composed of two buttons: the top button (A piece) and the bottom nail (B piece). The two parts are combined by knocking. Due to the combination of the shape slightly like the Chinese "work" word, it was named "commercial word deduction." Such buttons are mainly divided into hollow I-shaped deduction, shaking I-shaped deduction, double-ring I-shaped deduction, double-colored I-shaped deduction, with drill collar and other words. At present, the use of industrial fasteners is widely used in the market. Clothing, accessories, and so on are all applied to the knuckles. In the process of purchasing knuckles, we are not sure that we will not know how to measure the sizes and specifications of the knuckles. Today, everyone is working with Xiao Bian to learn about the common specifications of the gongs and buttons. The button size specification of the I-button is not specific to each factory, but is more common: 16L (10MM), 18L (11.5MM) 20L, (12.5MM), 24L (15MM), 27L (17MM), 32L (20MM) ). Some alloy knobs are also larger, with 48L (30mm), but copper or iron buttons are generally below 40L (25mm). Note: 1L=0.625MM. When the customer requests a brand logo on the button surface, the current size of the copper button surface is 钮. The general production process for the stamping version is as follows: drawing artwork, solar panel, sculpting and boring head, and pressing a button on the button , The stamping die will be pressed on the punching machine and the buttons will be sent to the electroplating, assembly and packaging. Each unit costs 300 yuan and takes 7 working days. The amount of withdrawals from the buttonholes is generally a refund of 300 to 500 dollars for a single order, or a cumulative total of 500 dollars in three months (1 GROSS equals 144). Alloy type button to achieve the requirements of the customer's request map, to play alloy die casting mold, mold fee production plant costs 800 yuan, generally to receive customers 1000 yuan or 1200 yuan, the number of mold back is generally 100,000 sets or goods Amount up to 30,000 yuan to withdraw from the mold. The alloy die-casting mold is larger than the copper stamping die, and a die-casting machine with a cost of 100,000 yuan is needed to heat the zinc alloy raw material at a high temperature, so the production cost of the test machine proofing is higher.
