Product description, features and application domain information

Car engine exhaust manifold.In the range from room temperature to operating temperature, phase transitions should be avoided or minimized.Because the phase transition will cause the change of volume, resulting in internal stress or deformation, affecting the product performance and life.Therefore, the matrix material is preferably stable ferrite or austenite structure.The main failure form of cast iron parts working under high temperature is corrosion under high temperature. After the oxidation of constituent phases in the tissues (such as graphite carbon), the volume of oxide is larger than the original volume, causing irreversible expansion of the casting.Although the intermediate CAM also pushes the intermediate rocker arm, since the rocker arm is separated, the other two rocker arms are not controlled by it, so the valve will not be affected.When the engine reaches a certain set of high speed, the computer will command the solenoid valve to start the hydraulic system, push the rocker arm of the small piston, so that the three rocker arm lock into a body, driven by the middle CAM c, because the middle CAM is higher than the other cams, the lift is large, so the intake valve open time is extended, the lift is also increased.

We have accumulated a lot of experience in aluminum casting over the years.Each process has a professional staff to operate.

The optical scanner is divided into x-direction scanning system and y-direction scanning system. Each servo motor shaft is fixed with a laser reflecting lens.Each servo motor is controlled by a digital signal sent by the computer.

The purpose of the focusing system is to focus parallel laser beams on a single point.Mainly USES the f - theta lens, different f - theta lens focal length is different, marking effect and scope is different also, fiber laser marking pause with imported high-performance focus system, the standard lens focal length f = 160 mm, effective scanning range Φ 110 mm.Users can choose the model of lens according to their needs.

Quality control

We have professional testing personnel to use a variety of equipment to control the quality of products

This device adopts precise microporous membrane filter, vacuum filter the fluid to be detected, the fluid particle pollution in the intercept on the membrane surface, and then the membrane filter with color standard colorimetric method, matching the weighing method and microscope observation method and instrument analysis method, the fluid particles of pollutants contained in the size, number, composition analysis.Filter membranes with different properties and diameters were selected according to the properties of the fluid, particle size and analysis purpose.

All the methods used in this device are in accordance with ASTM standards, and also meet the standards of several ministries and related industries in China.And precise, accurate, fast, simple, convenient.

In order to ensure the quality and reliability of engines, aviation, semiconductors, data storage, medical equipment, communications, precision instruments and wear monitoring of large-scale industrial and mining equipment, cleanliness testing equipment is mainly used for the analysis and evaluation of surface cleanliness of these products.

Technical strength

We have a strong professional technical team and r & d strength, as well as a variety of certificates.
