Recently, word "helmet" has gone viral on Moments and on major social platforms! Netizens are constantly discussing search for helmets and complaining about increase in prices for helmets.
At heart of these heated discussions is launch of new One Helmet, One Belt policy. From June 1, 2020, a helmet protection campaign will operate throughout country; " - safety belt).
What is demand for helmets under New Deal? According to analysis by China National Finance Securities, helmet manufacturers with a daily output of 2,000 pieces are large manufacturers and usually do not have large investments in equipment and excess production capacity. Under new requirements of “one helmet, one belt” policy, demand gap for new helmets will exceed 200 million.
The "one helmet and one strap" principle is declining sales of helmets
With gradual advancement of "one helmet, one strap" initiative, helmets have become a hot topic and their sales have also started to sell well.
Since May 10, traffic control department of Suzhou Public Security Bureau has reportedly implemented comprehensive management of electric bicycle helmet wearing in city, and helmet sales in Jiangsu have grown by 164%. year after year from May 1st!
Studies have shown that majority of deaths in motorcycle accidents are caused by head injuries, and wearing a crash helmet correctly can reduce the risk of death in an accident by 60-70%.
The promotion is currently ongoing under new "one helmet and one harness" policy.
The helmet automation industry may welcome a short-term outbreak
SIFC noted that, as with masks, helmet automation industry will grow rapidly. Helmet automation includes tumble dryers, suction machines, injection molding machines, machine tools (mould opening), loading and unloading robots with Cartesian coordinates, etc.
According to our data, price of summer helmets has increased by 2-3 times, and price of winter helmets has increased by 3-4 times, and daily sales in many stores have increased by 10 times.
China International Finance Securities believes that helmet automation industry portends a short-term explosion, and companies that will directly benefit will include Yizumi (Injection Molding Machine), Topstar (Cartesian Coordinate Robot + Auxiliary Machine for Injection Molding Machine pressure + injection molding machine), Xinjie Electric / Inovance Technology (Parts).
In addition, injection molding machine manufacturers such as Borch and Tairui Machinery also provide related helmet production equipment. For example, Borch claimed that its BS-III servo energy-saving machines have large power, precise control, stable performance and versatility. Helmet production.
What are main body materials?
At critical moments, helmet can become a "protective shell" that protects driver and passengers from serious injury. So, from what material can a helmet perform a strong protective function?
For shell of helmet, materials such as engineering plastics, glass fiber, carbon fiber and other materials are commonly used, lining of middle layer is usually made of polymer foam, and inner layer of helmet is mainly a fabric layer made of polymer fiber fabric.
In terms of helmet material supplies, Taiwan Chimei, Nanjing Julong, Kingfa Technology, Wanhua Chemical, Sunwill and Times New Materials have material supplies. For example, PC/ABS alloy supplied by Kingfa Technology has characteristics of high rigidity and high impact resistance; Taiwan Chimei provides special materials for ABS helmets with ultra high impact strength, etc.
ABS material, which is an engineering plastic, has excellent comprehensive physical and mechanical properties, good mechanical properties, good low temperature impact resistance, excellent wear resistance and good dimensional stability.
PC Polycarbonate is a durable thermoplastic resin. High strength (can meet needs of bulletproof glass), good fatigue strength, dimensional stability and low creep (very little change under high temperature conditions).
The performance of PC+ABS alloy is better than that of ABS. Currently, domestic alloyed materials are widely used in helmets.
Fiberglass reinforced plastic
Fiberglass-reinforced plastic, also called FRP, is made of fiber-reinforced plastic, which is strong, pressure-resistant, impact-resistant and tough.
Carbon fiber material
Carbon fiber is a new type of fibrous material with more than 95% carbon content. It has characteristics of high strength, high modulus, low density and small coefficient of linear expansion in terms of physical properties. And new materials. with mechanical properties.
Helmet liner is usually made from polymer foam, mainly because they are easy to process and have a more comprehensive energy absorption capacity. The foam material is placed between inner shell and outer shell, filling space between inner shell and outer shell and playing role of cushioning and impact protection.
Expandable polystyrene, commonly known as Styrofoam, is a thermoplastic material that is different from conventional foam materials. After heating and foaming, it contains 3-6 million pieces per cubic meter. Independent airtight air bubbles containing more than 98% of air volume.
EPS expanded polystyrene foam is used mainly because it is an impact resistant material with impact and shock absorbing effect. Its low density and light weight are also one of reasons this material is used in safety helmets.
Another lining material, EPP foam, also has good impact resistance and cushioning effect. EPP is a highly crystalline polymer gas composite material with excellent performance, which has become one of fastest growing new compression buffer thermal insulation materials due to its excellent performance.
List of motorcycle helmet types, performance and safety standards
A motorcycle helmet is a special device used to reduce injuries to driver's head in road traffic accidents. A helmet usually consists of a shell, a buffer layer, a comfortable lining, a wear device, and goggles.
The shell and buffer layer are key parts of a helmet that absorb impact energy and protect head from injury. Glasses protect your eyes better. The "reliability" of device also affects protection of helmet. The effects are direct.
Depending on shape and design, there are two types of helmets: a full helmet and a half helmet. The main difference between them is the different degree of protection.
Indicates type of helmet.
According to different applicable objects, helmets can be divided into two types: type A helmets and type B helmets. Type A helmets are suitable for motorcycles with a total displacement of 125cc. See and more, and there are two types of helmets. Shapes: Full Face and Half Face Helmets Type B Helmets Suitable for motorcycles with total displacement less than 125cc. Cm. Its volume and weight is less than type A helmets and they are all half face helmets. helmets.
Strict technical inspection is key to ensuring quality and safety of helmets. Penetration characteristics” and other 10 points of testing.
Among them, "Crash Energy Absorption Efficiency" and "Penetration Resistance Efficiency" are representative measures of helmet protection performance.
How to ensure quality when buying a helmet? Safety helmets are subject to mandatory national certification, commonly referred to as "3C certification". When buying a helmet, be sure to check helmet conformity certificate and check whether it has passed certification test required by National Compulsory Standard "Motorcycle Helmet" (GB811-2010) and check whether it has passed CCC certification. .
National standards for motorcycle helmets and CCC certification rules. Those who are not CCC certified must not be manufactured, sold, imported, or used in other activities.
When users purchase additional helmets, they are identified by "CCC" logo affixed to them and do not use non-CCC certified helmets.
