Truck Water Glass Lost Wax Casting

Gravity casting is well understood, that is, pouring liquid metal into the wheel hub mold to cool and form it. This method is the least expensive and most efficient, but the worst quality. In the event of a collision, the hub can easily break.

Second, low pressure casting. Low pressure casting is a small upgrade to gravity casting. It's the same at first. The liquid metal is poured into the mold, but the low-pressure casting process applies a constant pressure to it, so that the molecular density of the metal is higher and the hub is stronger.

The last is spinning casting. Spinning casting can be seen as an upgraded version of low pressure casting. A simple understanding is to perform secondary processing and rotary stamping of the cast hub while heating.

The Hub Technology Is Divided Into Several Grades

Wheel hubs are divided into two grades according to the big grade, one is cast and the other is forged. Forging is better than casting. Forged wheels are the superlatives.

Generally speaking, the wheels of ordinary cars are cast, and the wheels of high-end cars and sports cars are forged.

If subdivided, wheel technology can be divided into four grades, because casting can be divided into three grades.

The three grades of casting are from low to high: gravity casting, low pressure casting and spinning.

Gravity casting is well understood, that is, pouring liquid metal into the wheel hub mold to cool and form it. This method is the least expensive and most efficient, but the worst quality. In the event of a collision, the hub can easily break.

Second, low pressure casting. Low pressure casting is a small upgrade to gravity casting. It's the same at first. The liquid metal is poured into the mold, but the low-pressure casting process applies a constant pressure to it, so that the molecular density of the metal is higher and the hub is stronger.

Precautions For Wheel Modification

(1) Pay attention to the wheel size:

When refitting a car wheel, we need to pay attention to the size of the wheel. Many car owners think that as long as they don't touch the outside sheet metal, they can modify the wheels. But with the tires removed, we could see that there were a lot of places where it was easy to get stuck, especially when the vehicle was going over some bumpy roads. Therefore, when modifying the wheels, we need to pay attention to the size. While many oversized wheels can improve aesthetics, they may differ in practicality.

(2) Brake calipers should pay attention to:

Brake calipers play a very important role in braking, but many car companies may use large calipers for safety when building cars. If the new wheels don't fit the modified calipers, they can easily get stuck on the brake calipers when braking. Once these wheels are installed, there is friction when driving.

(3) Tire width:

After driving for a period of time, observe the wear of the car tires, and observe whether there is wear on the inside and outside of the tires. If the tire is too wide, it is easy to get caught in some parts during driving.

(4) Pay attention to the hub bearing:

Automobile wheel bearings need special tools and the correct method to disassemble. During the installation process, the bearing should not be damaged, so as to avoid abnormality during use.

Attachment: Misunderstanding of wheel modification:

(1) Pursue cheap and buy imitation products:

This is quite common during the day-to-day modding process. Genuine wheels are expensive, and some car owners choose some similar products. Similar things are similar in appearance and design, but they will be very different in use. Abnormalities are prone to occur during use, and driving safety cannot be guaranteed.

(2) Just look at the style:

Different styles of car wheels have different appearances. Many car owners only focus on the style of the wheel, not the performance of the wheel. It is recommended that car owners pay attention to the performance and practicality of the wheels when refitting. They need to understand the data of the car wheels when purchasing, and then make targeted plans.

Post Casting Process

1. Heat treatment: annealing, carbonization, tempering, quenching, normalizing, surface tempering

2. Processing equipment: CNC, WEDM, lathe, milling machine, drilling machine, grinder, etc.;

3. Surface treatment: powder spraying, chrome plating, painting, sandblasting, nickel plating, galvanizing, blackening, polishing, bluing, etc.

Moulds and Inspection Fixtures

1. Mold service life: usually semi-permanent. (except for lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.

Quality Control

1. Quality control: the defective rate is less than 0.1%.

2. Samples and trial run will be 100% inspected during production and before shipment, sample inspection for mass production according to ISDO standards or customer requirements

3. Testing equipment: flaw detection, spectrum analyzer, golden image analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine;

4. Provide after-sales service.

5. The quality can be traced back.
