1. Overview of springs
a. What is a spring?
- A spring is a mechanical component created by bending or twisting a metal wire into a specific shape. The spring can maintain its shape when compressed or stretched and can return to its original shape when the load is removed.
- Springs are commonly used in various applications, including electronic devices, industrial machinery, automobiles, furniture, beds, and other household products. Common types of springs include compression springs, extension springs, torsion springs, and flat springs.
- The properties of a spring, including stiffness, compression, elasticity, and durability, can be adjusted by changing the size, diameter, number, and spacing of the spring’s coils, as well as the material and manufacturing process.
- The types of springs manufactured in Vietnam include metal springs, stainless steel springs, and rubber springs. Among them, metal springs are the most popular product used in many industries, including automotive, electronics, refrigeration, furniture, construction materials, and sports.
- Some of the leading companies in the spring manufacturing industry in Vietnam are Viet Thang, Quang Minh, Thep Mien Nam, Thep Viet Nhat, Long Hung, Nam Kim, etc. These companies all meet product quality and safety standards and are building cooperative relationships with foreign partners.
b. Types of spring manufacturing machinery
To manufacture springs, businesses often use the following types of machinery and equipment:
- Spring coiling machine: This is a type of machine used to coil springs from steel wire or metal wire.
- Spring cutting machine: This machine is used to cut spring parts to the correct length.
- Spring bending machine: This machine is used to bend springs into the required shape and size.
- Spring polishing machine: This machine is used to polish and clean spring parts before they are put into manufacturing or sold.
- Spring testing equipment: These are devices used to check the quality and accuracy of spring parts.
In addition, spring manufacturing businesses also use other equipment and technologies such as cutting machines, punching machines, and CNC machining machines to manufacture spring parts with high accuracy and meet customer needs.

b. Training duration
Initial safety training duration
- The total training duration is at least 24 hours, including the examination time.
- 8 hours of theoretical study on the system of policies and laws on occupational safety and health
- 8 hours of theoretical study on basic knowledge of occupational safety and health
- 4 hours of theoretical study on specialized training content
- 2 hours of practical study on specialized training content
- 2 hours of theoretical examination at the end of the training course
The safety training center will distribute the time into many training sessions depending on the time arrangement for employees. But usually, there will be 6 training sessions, and the course will take place for 3 days, provided that the manufacturing company can arrange continuous study time.
Periodic safety training duration
- Before the occupational safety card expires, if workers want to have it re-issued, they must undergo a periodic occupational safety training course, with the periodic safety training duration being at least 50% of the initial safety training duration.
Explanation: The total periodic occupational safety training duration is at least 12 hours, including the examination time. After completing the periodic training course and passing the examination, workers will have their occupational safety card re-issued or renewed.

d. Occupational safety card
After completing the occupational safety training course and passing the examination, workers will be issued an occupational safety card (in practice often called a Group 3 occupational safety certificate).
The Group 3 safety card will clearly show information such as: full name, date of birth, specific job and working environment. It also includes the training duration, red stamp, and signature confirming completion of the training course.
According to the regulations on issuing safety cards specified in clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:
- If there is an employment contract between the employer and the employee, the employer must sign, stamp, and seal the safety card for the trained person in Group 3 after they have gone through the training course from the occupational safety training unit and passed the examination.
- If the worker is a freelance or seasonal worker and does not have an employment contract, the training unit must sign, stamp, and seal the safety card for the worker after they have gone through the training course from the occupational safety training unit and passed the examination.
