Diamond segment molding process

Diamond segment molding is a very important step in the production process, and various parameters need to be strictly controlled to ensure the quality of the segment.

The key to mold loading is to control the distribution and arrangement of diamond particles to ensure the strength and wear resistance of the segment. During the molding process, parameters such as the mixing ratio of diamond particles and metal powder, pressing force and temperature need to be precisely controlled, otherwise the quality of the segment will be affected.

In addition, the diamond segment also needs to be sintered, that is, to sinter it at high temperature to improve its hardness and strength. The control of sintering temperature, time and atmosphere also has a great influence on the quality of the segment.
The general process of diamond segment mold loading is as follows:
Prepare the mold: first, prepare a mold of suitable size and put it in a coolant to cool it down.

Preparation work: before starting the mold loading, it is necessary to clean and inspect the segment and the mold to ensure that the surface is clean and flat, free of impurities and damage.

Applying release agent: apply a layer of release agent inside the mold to prevent the diamond segments from sticking to the mold and facilitate subsequent removal.

Place diamond segments: place the pressed diamond segments inside the mold, pay attention to even distribution, and avoid gaps and cavities.

Selection of filling material: choose a suitable filling material to fill the mold, the choice of filling material is related to the material and shape of the diamond block. Usually the filling material is metal powder, resin, etc.

Closed Mold: close the mold by machine or by hand, sealing the filler material and diamond segments inside the mold.
In a word, the molding of diamond segment is a key production link, which needs to be operated strictly in accordance with the prescribed procedures and requirements to ensure the welding quality and the stability and durability of the segment.
During the molding process of the diamond segment, the following problems may occur:
Unreasonable mold design: if the mold design is unreasonable, such as dimensional deviation, uneven wall thickness, etc., the quality of the diamond segment will be unstable. The solution is to carry out sufficient simulation and testing in the design stage to ensure that the mold design is reasonable.

Uneven distribution of diamond particles: diamond particles may be unevenly distributed during the mold loading process, resulting in problems such as uneven surface of the segment and insufficient strength. The solution is to fully stir the diamond and powder before loading the mold, and fully compact it when loading the mold.

Improper ratio of diamond and metal powder: improper ratio of diamond and metal powder may lead to problems such as unstable quality and easy breakage of the segment. The solution is to choose the appropriate proportion according to the product requirements, and mix it thoroughly before loading the mold.

Mold wear: molds that have been used for a long time may wear out, resulting in problems such as unstable quality of the segment and dimensional deviation. The solution is to check and maintain the mold regularly, and replace the mold if necessary.

The above are the problems and solutions that are likely to occur during the molding process of diamond segments. To ensure the quality and stability of the molding, sufficient technical knowledge and experience are required.
