RNOX Helmet
In recent years, more and more people have begun to pay attention to road safety and equipment. Bicycle helmets have become essential products during riding. The production process of bicycle helmets is also very complicated.
The main component of the bicycle helmet is a hard material made of polystyrene. The production process of bicycle helmets can be divided into 6 stages: material selection, mold design, shell forming, fitting and glue setting, paint film forming, quality testing.
The first step of producing a bicycle helmet is the selection of raw materials. The selection of raw materials is very important to ensure the quality and safety of the helmet. The commonly used resin is polystyrene, a thermoplastic material with excellent resilience and deformation, good energy absorption performance and a certain amount of elasticity. The resin is processed into granular or block particles and placed in a hopper. The material is sent to the injection molding machine and heated to melt.
The second stage is the design of the mould. Through computer-aided design, the mold is designed according to the shape and size of the helmet. The ideal mold should not only ensure the shape and size of the helmet, but also density, uniformity and strength of the helmet.
The third stage is shell forming. The molten material injected into the mold is cooled, frozen and finally fixed in the form of a helmet shell. The shell can provide protection while maintaining the flexibility of the helmet.
The fourth stage is the assembly of the components. The components include the inner lining of the helmet, the adjustable cushion, the strap buckle and the inner cushion. All these parts must be assembled accurately according to the requirements before the next step.
The fifth stage is the forming of paint film. This stage is mainly to paint the helmet, which is also very important in terms of style. The forming of the paint film depends on the color matching and spraying skills of the paint worker.
The last stage is quality inspection. After the bicycle helmet is completed, a series of tests must be conducted including size, weight, elasticity, strength, safety and performance of the helmet, in order to determine whether the helmet meets the safety requirements.
In general, the production of bicycle helmet is not an easy task. It needs to go through 6 steps from material selection to quality inspection to ensure the safety of the helmet. As a cyclist, you should do a good job in the selection and safe use of the helmet in order to guarantee the safety of yourself and other riders.
