Vibrating screening equipment is an important equipment necessary for mining, mineral processing, coal processing, building materials, chemical industry and other departments, and its performance directly affects the production capacity and technical and economic indicators. For vibrating screen, the same fault may be caused by different reasons, and the solution may not be the same.

The heat-affected zone is the region where the microstructure and mechanical properties of the material change due to the effects of heat (without melting) during the welding process. The microstructure and properties of the weld metal resulting from recrystallisation are related to the chemical composition of the weld, the cooling rate, and the post-weld heat treatment.

In the field of precision manufacturing, the demand for multi-species and small-lot orders is increasingly becoming mainstream, with companies in the aerospace, precision mould and medical device industries

The main reason why novice welders can't match the current and voltage is that they don't know the relationship between the two, and they don't know what role they play. Current is to control the weld depth (current can also be understood as the wire feed speed, the greater the current, under the condition of constant voltage).

Many factories are also exploring various ways to tackle the problem of welding fume pollution in their welding workshops; however, due to certain factors, efforts to control welding fumes are often unsatisfactory, failing to meet environmental assessment standards, or having passed the environmental assessment at the time

我们通常把加工工艺分成减材料和加材料两种，我们大多数采用的都是减速材料的加工方式，加材料也有，一般叫做成形，比方说注塑成型，这就是加材料的方式，我们要说的是减材料

In the field of mechanical manufacturing and equipment supply, CNC machining is a core process underpinning the production of precision components. Many manufacturing companies have struggled to find reliable service providers: either after-sales support is slow to respond, making it difficult to find a point of contact when problems arise; or the provider has few case studies to demonstrate their capabilities.
