Bloc de positionnement en céramique de carbure de silicium

Bloc de positionnement en céramique de carbure de silicium is a high-end industrial positioning component made of advanced ceramic material – silicon carbide, through precision machining. It is not an ordinary positioning block, but designed specifically to solve positioning problems in extreme environments such as high temperature, high wear, and strong corrosion. With the excellent physical and chemical properties inherent in silicon carbide materials, this product far exceeds traditional metal or ordinary ceramic positioning components in terms of precision retention, service life, and stability, and is an indispensable key component in modern high-end manufacturing.

Avantages du matériau de base :
Ultimate hardness and wear resistance: The hardness of silicon carbide is second only to diamond and cubic boron nitride, far exceeding metal materials such as mold steel and tungsten steel. This means that during frequent positioning, clamping, and friction processes, it can effectively resist wear, maintain initial dimensional accuracy for a long time, and greatly extend the life of itself and the workpiece in contact with it.
Excellente stabilité à haute température : Silicon carbide can still maintain its strength and hardness in high-temperature environments above 1000 ° C, while ordinary metals have already softened and deformed. This makes it an ideal choice for fixtures and positioning mechanisms in thermal equipment such as vacuum high-temperature furnaces and sintering furnaces.
Excellente résistance à la corrosion : It has strong resistance to most acid, alkali, and salt melts, and can work stably in highly corrosive chemical environments without rusting or corroding like metals.
Low thermal expansion coefficient&high thermal conductivity: The thermal expansion and contraction effects are minimal, ensuring stable positioning accuracy even under drastic temperature changes; At the same time, high thermal conductivity is conducive to rapid heat dissipation and avoids local overheating.
High rigidity&lightweight: It has a high elastic modulus (rigidity), minimal deformation under stress, and a density lower than steel, achieving a perfect combination of lightweight and high rigidity.

Quels problèmes le produit peut-il résoudre ?
The emergence of silicon carbide ceramic positioning blocks directly addresses and solves many pain points of traditional positioning components in high-end applications:

1. Solve the problem of “accuracy degradation”:
   Traditional pain points: Metal positioning blocks may experience size changes due to wear and tear during use, resulting in a gradual decrease in positioning accuracy and requiring frequent adjustments or replacements, which can affect production pace and product consistency.
   Our solution: The extremely high wear resistance of silicon carbide ensures its long-term stability in size, fundamentally solving the problem of accuracy degradation caused by wear and ensuring high consistency and yield in mass production.
2. Solve the problem of “high temperature failure”:
   Traditional pain points: In high-temperature processes such as welding, brazing, and sintering, steel positioning blocks may deform, oxidize, and even adhere to the workpiece due to thermal softening, resulting in positioning failure and product scrap.
   Our solution: The excellent high-temperature performance of silicon carbide allows it to remain “intact” at high temperatures, without deformation or softening, providing a reliable and accurate positioning benchmark for high-temperature processes.
3. Solve the problem of “chemical corrosion”:
   Traditional pain points: In semiconductor wet etching, chemical equipment, or certain medical environments, metal components are prone to corrosion, producing pollution particles or self damage, polluting the process environment and increasing maintenance costs.
   Our solution: Silicon carbide itself is an inert material with strong corrosion resistance, which will not pollute the workpiece and environment, especially suitable for fields with extremely high cleanliness requirements.
4. Addressing the issue of high maintenance costs:
   Traditional pain point: Frequent replacement of worn or damaged positioning blocks not only increases spare parts costs, but also leads to valuable equipment downtime.
   Our solution: The ultra long service life significantly reduces the frequency of replacement and maintenance downtime. Although the single investment is high, the comprehensive cost and full lifecycle benefits far exceed traditional materials.
