Mold


Our company has developed automobile steel wheels and tubeless wheel molds for more than ten years. The mold body is a high-quality forged steel body, the working part is made of high-quality tool steel, and heat treated. It has the advantages of reasonable structure, convenient installation and use, and long service life. It is welcomed by users and enjoys a high reputation in the domestic industry.

Operating methods and equipment characteristics of the spoke spinning machine


The development history of metal spinning forming technology in China is nearly 40 years, and its application in national defense industry is particularly extensive. Research and application level is very high, especially in the spinning forming process and equipment, has been in the domestic position, spinning machine design and manufacturing capacity is also very strong. The following is a description of the operating methods and equipment characteristics of the spoke spinning machine.

Equipment Gear Classification Introduction


Equipment gears can be classified according to tooth shape, gear shape, tooth line shape, tooth surface and manufacturing method. The tooth profile of the gear includes tooth profile curve, pressure angle, tooth height and displacement. Involute gears are relatively easy to manufacture, so in modern equipment gears, involute gears account for an absolute majority, while cycloid gears and arc gears are less used. Let's take a look at the introduction of equipment gear classification.

Tubeless wheel rim rolling machine related introduction


The rim is also called the rim, which is one of the components of the wheel. The function of the tubeless wheel rim rolling machine is to roll the rim, and different types of rim rolling are different. The following is a detailed introduction.

China becomes Germany's fourth largest export market

China becomes Germany's fourth largest export market


According to the "Financial Times" German website, benefiting from China's economic prosperity, German exports to China have grown rapidly. Since exports are the main driving force of German economic growth, a large part of German economic growth should be attributed to China. The authoritative research institution Ifo Economic Research Institute recently announced that China has become Germany's fourth largest export market for goods, behind France, the Netherlands and the United States, ranking three places ahead of 2010. In 2012, China will become Germany's second largest export market. The growth of German exports to China mainly came from products such as computers, machinery and automobiles, and the export of some products increased by more than 30%. German machinery and equipment enterprises become China's giant

Introduction of noise generation of injection molding machine

Introduction of noise generation of injection molding machine


It is reported that abnormal noise is generated, which indicates that parts are damaged or improperly adjusted. The reason should be found out according to the location of the noise. 1. Insufficient hydraulic oil in the oil tank, air intake by the oil pump or dirt blockage of the oil filter will cause the oil pump to be short of oil, causing bubbles in the oil to be discharged and hit the blades to produce noise. The solution is to check the oil volume to prevent air inhalation and Clean the oil filter. 2, the hydraulic oil viscosity is high, increase the flow resistance, need to replace the appropriate hydraulic oil. 3. Due to the damage of the bearings or blades of the oil pump or motor, the concentricity deviation of the coupling causes noise, and the concentricity must be adjusted or parts must be replaced. 4,

Introduction to annealing for mold making

Introduction to annealing for mold making


Annealing includes spheroidizing annealing after forging and stress relief annealing during mold making. Its main purpose: to improve the crystalline structure in the raw material stage, to facilitate processing and reduce hardness, to prevent deformation and quenching cracks after processing and to remove internal stress. 1) spheroidizing annealing. Die steel after forging, the internal structure of the steel into unstable crystallization, high hardness cutting difficulties, and this state of the steel, internal stress, easy deformation and quenching after processing, poor mechanical properties, in order to make the carbide crystallization into a stable spheroidizing organization must be spheroidizing annealing. 2) stress relief annealing. Machining of die steels with residual stresses
