Product features and applications
With the rapid development of the electronics industry, the requirements for the sintering process of electronic components have become increasingly strict, and higher demands have been placed on the precision, high-temperature resistance and service life of the tooling molds. This has led to more precise and reliable designs for electronic sintering tooling molds. We are a reputable Chinese manufacturer dedicated to producing precise, sturdy and durable electronic sintering tooling molds. We have a strict quality control system and employ the most advanced manufacturing processes and technologies to ensure that each set of molds meets the highest standards and industry norms of our customers.
Core advantages list
The high-precision size control and precise processing technology ensure that the key dimensions of each mold are controlled within ±0.05mm, guaranteeing the consistency and qualification rate of the sintered components.
Excellent high-temperature resistance is achieved by using high-purity graphite and special heat-resistant steel materials. These materials can operate stably at a temperature of 1600℃ for a long time without deformation, maintaining consistent geometric accuracy.
The optimization of the uniform temperature distribution mold structure, combined with high-quality heat-conducting materials, ensures a uniform temperature distribution during the sintering process, avoiding local overheating or under-sintering phenomena.
The special heat treatment process and surface treatment technology with long service life have significantly enhanced the wear resistance and corrosion resistance of the molds, and the service life is 3 to 5 times longer than that of ordinary molds.
The rapid demolding design of the mold structure takes into account operational convenience. It adopts an optimized demolding mechanism to reduce the adhesion between components and the mold, thereby improving production efficiency and yield.
The flexible customization capability can be tailored to meet the product specifications and production process requirements of different customers, providing a one-stop solution.
Technical capabilities details
Material selection and ratio: We select high-purity graphite materials (with a purity of ≥ 99.5%) and combine them with special heat-resistant steel frames to ensure that the mold not only has excellent high-temperature resistance but also has sufficient structural strength. The materials undergo strict heat treatment processes, which eliminate internal stresses and improve dimensional stability.
Structural design optimization is achieved through finite element analysis (FEA) technology to optimize the structure of the mold, ensuring a stable geometric shape even under high temperature and high pressure loads. The mold structure takes into account thermal expansion matching, effectively solving the problem of size changes under high temperatures.
The precision control system has strict quality control standards for each process from rough machining to finish machining. High-precision CNC machines are used for processing, and key dimensions are inspected using a three-coordinate measuring machine to ensure that each mold meets the design precision requirements.
The surface treatment process involves precise polishing and special coating on the mold surface. The surface roughness is controlled within Ra ≤ 0.8 μm, which effectively reduces the adhesion to electronic components and facilitates the demolding operation. The surface treatment layer has excellent high-temperature resistance and oxidation resistance properties.
The internal design of the thermal management technology mold incorporates an optimized heating and cooling system, ensuring the uniformity and stability of the temperature field during the sintering process. Combined with precise temperature control equipment, it can achieve a temperature control accuracy of ±5℃.
