Bicycle Magnesium Alloy Die Casting
Magnesium alloys have been widely used in rail transit, electronic communications, automobiles and other fields by virtue of their excellent properties of low density and light weight. Bicycle manufacturers have used magnesium alloys to process bicycle parts.
Qinhuangdao Zhongwei Precision Machinery Co., Ltd. is a new company specializing in the production of Bicycle magnesium alloy die casting integrated wheels. It integrates magnesium alloy product research and development, mold design, magnesium alloy die-casting production, magnesium alloy profile deep processing and product sales. It has domestic Professional product design, mold design team and magnesium alloy production and processing team. In addition, the company undertakes various types of die castings and magnesium alloy die castings. Qinhuangdao Zhongwei Precision Machinery Co., Ltd. currently has more than 10 cold chamber die-casting machines of 200T-1250T models, and a total of 3 hot-chamber die-casting machines of 88T-168T models. The excellent quality has created a gold reputation, making the other shore products. It quickly became famous at home and abroad. More than 70% of the products are exported to the United Kingdom, Germany, Japan, the United States, Taiwan and other countries and regions.

Product Feature
Magnesium alloys have been widely used in rail transit, electronic communications, automobiles and other fields by virtue of their excellent properties of low density and light weight. Bicycle manufacturers have used magnesium alloys to process bicycle parts. Many domestic and foreign companies have also begun to try to develop and use magnesium alloys to process bicycle parts, which have been favored by many customers. Magnesium alloys are very effective in processing bicycle frames.
Three advantages of using magnesium alloy to process bicycle frames:
1.Due to the relatively small mass of magnesium alloy, it is the lightest metal structural material at present, which can reduce the weight of the bicycle, thus making the cyclist more labor-saving and faster.
2.Magnesium alloy has good damping performance. The frame is processed by magnesium alloy, which makes the mountain bike ride on uneven mountains. It has a good vibration reduction function and can withstand large impacts, making the rider more comfortable.
3.Magnesium alloys have good casting properties. Based on this feature, it becomes easier to process bicycle frames from magnesium alloys, and bicycle frames can be CNC machined in small batches.
Processing Technology
1. Die casting method for magnesium alloy processing
Die-casting magnesium alloy has good fluidity, and solidification speed is fast after filling, and there will be no defects such as hot cracking and under-casting. Die-casting is divided into hot-chamber die-casting and cold-chamber die-casting. The hot-chamber die-casting method is commonly used in the production of bicycle frames. However, the replacement of bicycles is relatively fast, and the casting cost of die-casting parts is relatively high.
2. Welding method for magnesium alloy processing
Welding is an economical method of bending a wrought magnesium alloy into a frame. Compared with the die-casting method of bicycle frames, the welding method has high efficiency, stable processing control and lower cost.
3. Prospects of magnesium alloys
my country is the country with the most abundant magnesium reserves in the world and the largest magnesium exporter in the world. The country lists magnesium alloy as a very important metal material. It is believed that in the near future, magnesium alloy will not only be used in high-end bicycle products such as competition and off-road, but also will continue to develop in the direction of popularization.
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.
