1. steel wheels
also known as the rim hub, Hong Kong and Taiwan, is known as a bell. Car Wheel upgrades most common method is to switch to aluminum wheels, or used to increase the wheels to improve vehicle performance and appearance. Car rims from the material to the main points into steel wheels and alloy wheels (Alloy wheel), the most popular in the conversion market rims of course, alloy wheels, alloy wheels are divided into casting and forging molding two kinds of
most rims vehicle used was pressed and welded steel, the steel ring currently very precise outer manufactured to fit tubeless tires.
Classification rim
manufactured in different ways, the rim is divided into casting (Casting) and forging (Forged) two categories. Casting is divided into gravity casting (Gravity Casting) and low-pressure casting (Low Pressure Casting) two kinds. Gravity casting the liquid alloy is poured into a mold where cooling molding, the rim due to the manufacturing process is simple, durable molds, becoming the lowest-cost manufacturing methods. Producing a low pressure with small pressure pressed into the liquid alloy in the mold, so that the average molecular distribution of less clearance hole, the shape may be more complex and sophisticated.
Structural Characteristics
Structurally rim can be divided into a plurality and structural members. Multi-piece rims and spokes frame that is manufactured separately, and then screws, they are now able to buy one modified wheels. The advantage is the ease of manufacture aspect, since the frame can be used to roll steel; on the other hand easy maintenance and exchange more models, such as the same model can be equipped with different width spokes frame, so that the production cost is further reduced. Up to now, more than the wheels because the number of parts and more, production processes and more, and may look a sophisticated, elegant feel, so the price is even more expensive than the one-piece wheels, but the wheels more than usual heavier, but not as rigid forged wheels.
