Introduction to Forging Process

Forging is a kind of process method which exerts pressure to metal material with metal forming machine to make it plastic deformation to get the casting of specific mechanical performance, shape and dimension. It is one of the two parts of forging and pressing. Through forging, the defects of loose cast condition of metal generated during smelting process can be eliminated and the micro structure of the metal can be improved.

The Protection of The Transition Joints

Coefficient of thermal expansion of copper and aluminum differ greatly. Than the thermal expansion coefficient of aluminum is about 36% that of copper, in the transition joint heating copper material will be squeezed and not fully recover after cooling. Thus, in the long run Lengrebujun term repeated temperature changes (e.g., power and power, a small load and a large load, alternating hot and cold weather, etc.), the contact surface tends to have a greater impact gap the contact area, resulting in poor contact of the contact resistance increases further.

Control of The Three Hydraulic Device Leakage Principle

In order to control the leakage of hydraulic system, first of all to each part of the hydraulic device leakage limit. To control the leakage by sealing device and the correct design and use, by the sealing device effectively play a role. Hydraulic device leakage reason is in many aspects, both has the design, manufacture, installation problems, there are maintenance problems. So, we must pay great attention in all aspects, basic standards are as follows:

Hong Chong Technology Introduction

"Hong Chong" is actually a hot extrusion process, because the manufacturing in coastal area of Zhejiang industry, especially the pipeline hardware manufacturing industry, if someone says "extrusion", not much can immediately notice the meaning of people, when it comes to "red" two words, so people will know it is what kind of process? The mold of what? Which product? In addition, the name "process red" this name and reality closely relationship and other sound reasons, so it is easy to accept.
