In-line skates...
In-line skates are a type of roller skate used for inline skating. Including two front and two rear wheels, inline skates usually have two to five wheels in a line. Something, especially for entertainment, is a rubber "stop" or "brake" block that attaches to the back of one or sometimes both skates so that the skater slows or stops by bending the leg back on the leg with the brake skate. can do.
In-line skate has polyurethane wheels aligned on a strip or truck (chassis) made of plastic or lightweight aluminum. The truck holds the wheels with bolts, and on some models the wheels can be disassembled and replaced. The truck is attached to a molded boot, made of polyurethane, which holds the buckle (made of plastic, velcro straps, or cloth laces). Some in-line boot shells are combinations of leather or polyurethane plastic. The brakes are made of hard rubber or polyurethane, which is located on the back of the skate.
Shoe is designed to provide good ankle support by extending 3-4 inches (7-10 cm) above the ankle joint. The upper and lower parts of the boot are connected on each side of the ankle by a hinge system that allows the ankle to flex. For added comfort, the shoes are lined with materials that absorb sweat, usually covered with high density foam nylon clots. Wheels vary in hardness (duometer) and size (diameter). Generally, hard wheels, fast skates. The wheels have two ball bearings per wheel which are separated by a plastic or metal spacer. Bearings help the wheels spin faster and more freely. The spacer helps prevent the bearings from making contact with each other.
Raw Material:
In-line skate is a technical product. This high-grade polyurethane, copolymer plastics, or carbon fiber kevlar (the material used to make the bulletproof vest) are used to make the majority of in-line skating shells or boots.
In-line skatespolyurethane. Hard nylon or urethane plastic or steel is used for the chassis and brake components. The frame consists of wheels, they may be made of aluminum, carbon fiber or titanium. Fabric or plastic foam is used to show the line inside the boot. Steel is also used for ball bearings, buckles, on in-line skates.
Manufacturing Process:
Companies manufacture different skate components worldwide. For example, manufacturers of skate-board wheels also make in-line skate wheels. A company makes boot shells and chassis; The other manufacturer offers braking systems. In-line skates are manufactured using an assembly line process, whereby all components move down a conveyor belt and are assembled piece by piece.
Making the boot shell:
In-line boot shell injection moldings are made by a process. Urethane plastic is injected into the mold to form a boot shell, much like a ski boot. Dye can be added to color. The injection-molding machine ejects the finished boot.
Inserting the liner:
Fabric or plastic foam is cut into shapes and inserted into the boot shell. The amplitude of the liner must correspond to the foot of the skater.
Adding the attachments:
Shell cuffs (along with tongue), metal buckle, and plastic or velcro fasteners are attached to the shell. Most are prefabricated in pieces.
Assembling the wheel:
The frame, including wheels and bearings, is attached to the boot shell by a river or coupling system. The wheels are placed in a row and attached to the frame. Boot and frame injection are molded as a single unit.
Once the in-line skate is assembled, it is boxed and delivered to stores.
