Do Different Roller Skate Holders Have A Big Impact?

Partone Structure Classification

1. Two-piece knife holder

Two-piece knife holders are commonly found in middle and low-end casual shoes. Each knife holder is connected to it through a different structure on the bottom of the upper shoe, or the two pieces are first connected to each other through independent blocks, and then connected to the upper shoe through bottom nails.

2. Integrated knife holder

The one-piece knife holder is the most common in all kinds of roller skates today. The knife holder is integrally formed, and is fixed by connecting the shoe with bottom nails.

3. Split knife holder

The split tool holder is a multi-functional design, with multiple parts connected to each other. Common uses are length adjustment, shock absorption, replacement, etc.

Parttwo material classification

1. Aluminum alloy Alu aluminum alloy is a common tool holder material in the roller skating industry. It has the characteristics of low density and relatively high strength. Generally, it is commonly used as 6000 aluminum alloy series and 7000 aluminum alloy series. 6000 series is commonly used as 6061, which mainly contains two elements of magnesium and silicon. It has good workability, easy coating and good processability. It has sufficient strength, and it will be deformed by strong impact, but it will not break. The 7000 series is commonly known as 7005, which mainly contains zinc elements. It is an aluminum-magnesium-zinc-copper alloy and is a heat-treatable alloy. The ratio range of metals such as magnesium)

2. Other metals such as magnesium alloy Mag have low density (about 1.8g/cm3 magnesium alloy), high strength, large specific elastic modulus, good shock absorption, and greater impact load capacity than aluminum alloys, and the same strength as ordinary aluminum alloys The lower weight is about 20% lighter, but the rigidity is not as high as that of aluminum alloy, so for players with relatively strong strength, aluminum alloy is more suitable.

3. Other materials carbon fiber, wood, etc. This type of knife holder is relatively rare in the market. It is characterized by strong toughness and light weight, but its accuracy and rigidity are relatively average. It is mainly used for leisure roller skating.

4. Composite materials Composite fibers refer to chemical fibers made of two or more polymers, or the same polymer with different properties, through composite spinning. Common composite materials are glass fiber reinforced nylon, which is often used in extreme shoe sole plates and tool holders

Carbon fiber mixed with glass fiber, commonly used in the bottom plate material of speed skating shoes
