How does Yema Helmets produce safe and qualified helmets?

YEMA News
The electric motorcycle helmet is an important protective gear for riding safety. Its production process involves multiple key links, and strict control is required from design and development to finished product manufacturing to ensure the quality and safety of the helmet. Yema Helmets is a well-known domestic helmet brand established in 1991, integrating production, testing, development, creation, and sales. Today, we will introduce in detail the production process of YEMA Yema’s electric motorcycle helmets to answer how Yema Helmets produces safe and qualified helmets.

 

1、Design
The design and development of the helmet is the starting point of the entire production process. At this stage, the purpose, target user group, and functional requirements of the helmet are determined. First, the designer will create a concept drawing of the helmet to determine the appearance and style. Then, engineers use computer-aided design software (CAD) to create a 3D model of the helmet, while considering the structure, materials, ventilation system, and other functions of the helmet. At this stage, safety considerations are of great importance, and the design must meet the corresponding safety standards.

2、Injection Molding
The manufacturing of the helmet shell is one of the key technological steps. Generally speaking, there are several main shell manufacturing methods, including injection molding, pressure molding, and composite molding. Yema Helmets adopts the injection molding method, injecting the heated material into the mold and forming the helmet shell through high-pressure injection.

3、Shell Grinding, Painting, Decal Application, and Polishing
After the surface of the helmet shell is manually ground, the painting and decal application work is carried out. The decals are designed by computer, printed, and applied manually. Finally, after polishing treatment, the helmet shell is basically completed.

4、Manufacturing of the Buffer Layer
The manufacturing of the helmet buffer layer is equally important. EPS is a highly efficient energy-absorbing material that can reduce the impact force during a collision. The buffer layer is formed by a molding method using a mold. The EPS particles are heated and expanded, filled into the mold of the helmet lining, and then cured by high temperature to form the shape of the lining. The density and thickness of the lining will be adjusted according to different helmet models and standards.
5、Assembly
After the shell and buffer layer are manufactured, the assembly stage of the helmet begins. At this stage, the helmet shell and buffer layer are combined together, and accessories such as the neck strap, inner lining pads, adjustment system, and goggles are added. The assembly process requires a high degree of precision and quality control to ensure the stability and safety of the helmet.

6、Quality Inspection
Quality inspection is a crucial part of the helmet production process. Yema Helmets will conduct strict quality inspections at each stage to ensure that the helmets meet the safety standards and quality requirements. Safety tests will also be carried out on the helmets, including tests for penetration resistance performance, impact energy absorption performance, and the stability and strength of the wearing device, etc. Only through strict quality inspection can the safety performance of the helmet be guaranteed in actual use.

7、Packaging and Distribution
Finally, the helmets that pass the quality inspection will be packaged and prepared for shipment to the sales channels. The packaging of the helmets should protect them from damage during transportation. After the helmets are packaged, they will be distributed according to the requirements of the sales channels for consumers to purchase and use.

The production process of electric motorcycle helmets is a complex and rigorous process, covering multiple key links. Through the careful implementation and strict control of this series of steps, Yema Helmets can ensure the production of safe and qualified helmets, providing effective head protection equipment for riders.
