1. Anti-static and Conductive Shoes
These shoes are typically manufactured using two main methods: adhesive and injection molding. The equipment involved includes sewing machines, pressing machines, pull-up machines, stretchers, and solid machines for adhesives, while injection machines are used for injection molding. A full-size shoe last is also essential in the process. Testing equipment includes anti-static performance testing devices to ensure compliance with safety standards.
2. Toe Protection Labor Insurance Shoes
The production and process equipment for these shoes are similar to those used for anti-static shoes. However, the main testing equipment includes pressure (static pressure) testing machines and impact testing machines to ensure the toe cap can withstand heavy loads and potential impacts.
3. Acid and Alkali Protective Shoes
There are three common types of acid and alkali protective footwear:
- Acid-resistant leather shoes: These are produced using either adhesive or molding techniques. Testing equipment includes incubators, tensile testing machines, permeability test devices, Shore hardness testers, and analytical balances.
- Acid and alkali resistant rubber boots: Production involves rubber mixing machines and vulcanizing units. Testing equipment includes tensile testing machines, analytical balances, Shore hardness testers, and water inlet test devices.
- Acid and alkali plastic molded boots: These are made using plastic kneading machines and injection molding machines. Testing includes tensile testing, hardness measurement, and balance analysis.
4. Anti-piercing Labor Insurance Shoes
Like the first type, these shoes use similar production and process equipment. However, their testing involves a pressure testing machine and a standard piercing device to verify resistance against sharp objects.
5. Electric Insulation Shoes
In addition to the standard equipment used for other types, electric insulation shoes require rubber mixing machines, vulcanizing devices, and sewing machines. Testing equipment includes electrical insulation performance test devices and tensile testing machines to ensure they meet electrical safety requirements.

Various labor insurance shoes production equipment, testing equipment statistics
Special labor insurance shoes must undergo strict inspections by the labor safety supervision department or a certified product safety and quality inspection station. Only after obtaining the "production license" and "product certificate" can mass production be approved. But what are the key differences between the various types of labor insurance shoes?
