Hello,Welcome to YiMing!
As the traditional extruder parts are full hydraulic and curved elbow two different models, in the traditional common die casting without distinction, but if used for extrusion die casting is different. In conventional die casting and extrusion die casting, casting during filling, extrusion die-casting adds a master cylinder power forward step up the common casting is only natural cooling, no fill shrinkage step. The traditional die casting machine directly applies the extrusion die casting technology, and can only use its clamping force, and only the clamping force is a driving force forward. The magnitude of the die force determines the size of the extrusion force. Therefore, the clamping force of a full hydraulic press is its clamping force, and it can also be used as its extrusion force. The forward extrusion force of a curved die casting machine is equal to the force of the clamping cylinder force multiplied by the lever ratio of the locking mechanism, but it can not exceed the compressive strength that the clamping mechanism can bear.
With the increase of extrusion parts output in China, the development of the industry is very fast, mainly due to China unique market advantages. Aluminum alloy die castings are widely used, especially in the automotive industry, the demand for aluminum alloy die castings is very large. The automobile industry in our country has been developing rapidly in recent years. The demand for aluminum alloy die castings has been increasing rapidly, which has greatly promoted the development of aluminum alloy die castings industry in china. Especially in the light of the trend of automotive lightweight, there is a huge demand for the global aluminum alloy die casting market, not to mention the demand for the automotive industry in our country. At the same time, due to the optimization of auto industry upgrading, is gradually used Aluminum Alloy castings instead of castings, so as to continuously stimulation on Aluminum Alloy casting demand growth. The automobile industry is still in the stage of continuous development for our country. Under the impetus of the above trends, the advantages of our country aluminum alloy die castings industry are very obvious.
Vacuum extruder is divided into 3 types: soft plastic, semi hard plastic and hard plastic vacuum extrusion molding. It is mainly used with shale, coal gangue and fly ash and other raw materials required after crushing, adding water, stirring, pressing, vacuum, extrusion molding, and palletizing, calcining with certain strength, density and size of the sintered solid brick and hollow brick, brick making enterprises is the host equipment the. Compared with foreign countries, the production base of our country brick making machine is poor, which started late and has made great progress in recent years. However, there are still some gaps and deficiencies in the adaptability, complete set and abrasion resistance of the products. We should further study and develop a new brick extruding machine equipment which is suitable for the national conditions of our country and matches the advanced brick making process.
In view of the technical quality problems of extrusion machine parts industry, in order to implement the national policy of wall materials innovation, product quality checks extrder continuous tracking state quality inspection administration, so that the overall quality level of the product has changed greatly, improve product quality and stability, structural adjustment has taken a welcome step. Some of the key enterprises of brick extruder imported technology from developed countries, designed and manufactured high rigid extrusion or semi rigid plastic brick extruder with high extrusion pressure, high yield and strong wear resistance. It represents the industry level of brick extruder in our country. However, such products account for only about 10% of the market share. On the other hand, to promote the national wall reform policy, a part of the extrusion machine brick production enterprises to adapt to the requirements of enterprises, absorbing foreign advanced technology in the digestion, developed a suitable medium extrusion pressure, medium yield, price relatively high energy saving type, compact vacuum extruder the performance, to meet the basic needs of the construction and renovation of wall materials in our country, the market has been recognized and welcomed.
