How to make screws
Screws are indispensable fasteners in industrial production and daily life, and their manufacturing process involves multiple precision links. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce the production process, material selection and market trends of screws in detail, and display key information through structured data.
1. Screw production process
The manufacture of screws usually involves the following steps:
| steps | Description | key equipment |
|---|---|---|
| 1. Material preparation | Choose suitable metal wires (such as carbon steel, stainless steel, etc.) | Wire cutting machine |
| 2. Cold heading forming | The wire is pressed into the preliminary shape of the screw through a cold heading machine | Cold heading machine |
| 3. Thread processing | Use a thread rolling machine or lathe to process threads | Thread rolling machine, lathe |
| 4. Heat treatment | Improve the hardness and strength of screws | heat treatment furnace |
| 5. Surface treatment | Electroplating, galvanizing or coating with anti-rust layer | Electroplating tank, spraying equipment |
| 6. Quality inspection | Check size, strength and surface quality | Optical detector, tensile testing machine |
2. Material selection of screws
The material of the screw directly affects its performance and usage scenarios. The following are common screw materials and their characteristics:
| Material type | Features | Applicable scenarios |
|---|---|---|
| carbon steel | Low cost, high strength, easy to rust | General buildings and furniture |
| stainless steel | Corrosion resistant, medium strength, higher cost | Outdoor, humid environment |
| alloy steel | High strength, high temperature resistance, high cost | Automobile, aviation |
| Copper | Good electrical conductivity, corrosion resistance, high cost | electronic equipment |
3. Market trends of screws
According to the hot content in the past 10 days, the screw industry shows the following trends:
