Hunan Jingtan Automation Equipment Co., LTD.

When dealing with the production mode of multiple varieties and small batches, traditional equipment often has low efficiency due to the cumbersome process switching. The requirements for sintering temperature curves, holding times, and atmosphere conditions of different materials vary significantly. If the equipment does not have flexible process adaptation capabilities, frequent process switching will lead to a large amount of waste of auxiliary time and energy consumption. The vacuum sintering furnace for refined carbon adopts a modular temperature control design, equipped with a programmable controller and a human-machine interface. It can store multiple process heating curves. Operators only need to call the process formula of the corresponding product, and the equipment can automatically execute the entire process of heating, holding, and cooling, significantly reducing the time for production change and adjustment. This "one machine, multiple processes" design enables enterprises to avoid configuring multiple dedicated devices for different products, significantly reducing equipment investment and factory space occupation. The atmosphere switching function of the vacuum sintering furnace is another key to its adaptability to multi-variety production. The equipment can flexibly switch between vacuum and various protective atmospheres, meeting the full process requirements from degassing, degreasing to densification sintering. For materials that require treatment in a reducing atmosphere (such as anti-oxidation sintering of metal powders), hydrogen can be introduced during the sintering process. For materials that need to prevent the volatilization of alloy elements, the partial pressure sintering mode is adopted, and an appropriate amount of inert gas is filled in the high-temperature stage. The equipment adopts resistive heating. The graphite tube heating element has a long service life, good heating effect and is easy to maintain. This "multi-purpose in one furnace" design enables users to cover a wider range of process requirements with lower equipment investment.   The controllable cooling function of the vacuum sintering furnace during the cooling stage further enhances the process flexibility. The high-temperature section of the furnace body is cooled naturally, while the low-temperature section can be cooled at a faster rate by injecting positive pressure inert gas. Users can choose different cooling rates based on the sensitivity of the materials - slow cooling can be used for hard alloys that are prone to hot cracking, while rapid cooling can be adopted for materials such as stainless steel to enhance efficiency. The equipment adopts an internal circulation pure water cooling system and is equipped with a digital flow monitoring system. The modular design of the equipment also facilitates later expansion. Users can increase the furnace size or heating power configuration according to the demand for production capacity growth.

With the comprehensive technical advantages of "pre-stored multi-process curves, flexible atmosphere switching, and modular design", the vacuum sintering furnace of Jingcarbon demonstrates remarkable economic efficiency and adaptability under the production mode of multiple varieties and small batches.

The vacuum sintering furnace is a specialized sintering equipment developed by Hunan Jingtan Automation Equipment Co., Ltd. for fields such as cemented carbide, powder metallurgy, and special ceramics. During the sintering process of cemented carbide (WC-Co), the stability of the material's density and mechanical properties directly determines its performance in downstream applications. If the vacuum degree of a traditional sintering furnace is insufficient or the temperature field is uneven, it will cause residual pores or abnormal grain growth inside the material. The vacuum sintering furnace for refined carbon operates in a high vacuum environment. The higher the vacuum degree, the fewer chemical reactions occur in the material, which has a significant promoting effect on the shrinkage in the later stage of sintering, enabling the sintered parts to achieve higher density and more uniform microstructure. The equipment adopts an advanced furnace design concept and high-quality insulation materials to ensure the uniformity of furnace temperature under vacuum conditions. The temperature difference in the constant temperature zone can be controlled within ±7℃, ensuring that products at different positions in the same furnace batch achieve consistent sintering effects. The degreasing control of vacuum sintering furnaces is a key link to ensure product quality. Hard alloy billet contains forming agents such as paraffin and PEG. If these organic substances are not effectively removed before sintering, they will rapidly vaporize at high temperatures, generating high-pressure gas, which can cause the billet to crack or the surface to bubble. The vacuum sintering furnace for refined carbon adopts a combined process of "slow heating + high vacuum" in the low-temperature section, which enables the forming agent to decompose slowly and be fully discharged, avoiding damage to the green body caused by excessive degreasing. The equipment is equipped with a decoking system to enhance the decoking effect, making the atmosphere inside the furnace more stable and the product quality easier to control. At the same time, it extends the service life of the carbon felt and heating materials. Domestic and international brand temperature measurement elements are used inside the furnace to ensure the accuracy of temperature measurement.   The heating system of the vacuum sintering furnace adopts square cage-type graphite rods and rod combination heating, which is convenient for maintenance and suitable for both square and circular boat dishes. The maximum temperature of the equipment can reach over 2200℃, and it is compatible with various carbonization and sintering processes. The furnace body adopts a front door or double front and rear door structure, which is convenient for loading and unloading materials. The front and rear furnace doors can be opened, making operation convenient. The product performance is good and the quality is stable. It is a widely used sintering equipment in the hard alloy industry. The equipment can be pre-evacuated and filled with various inert gases, featuring high atmosphere exchange efficiency and meeting the full process requirements from degassing, degreasing to densification and sintering. The vacuum sintering furnace for refined carbon adopts a digital intelligent temperature control system, which automatically and precisely completes the temperature measurement and control process. The system can heat up according to the given heating curve and can store multiple process heating curves. The comprehensive PLC automatic control and protection system for water, electricity and gas achieves safety interlocking and features multiple audible and visual alarm functions such as over-temperature, sensor open-circuit, water pressure and furnace overpressure. The vacuum sintering furnace manufacturing center has established a 3D development platform for vacuum sintering furnaces, dedicated to providing customers with energy-saving, efficient, intelligent and safe professional vacuum sintering equipment. With the comprehensive advantages of "high vacuum environment, uniform temperature field, and integrated degreasing and sintering", the vacuum sintering furnace for fine carbon has become the main sintering equipment in the powder metallurgy and hard alloy industries.

Its market growth potential remains positive in the long term. Ii. Market Size From a global perspective, thin film deposition equipment is an important component of semiconductor equipment and, together with etching equipment and photolithography equipment, constitutes the core equipment system for chip manufacturing. The overall market size has reached the level of hundreds of billions of US dollars and maintains a stable growth trend. Among them, the growth of chemical vapor deposition (CVD) equipment and atomic layer deposition (ALD) equipment is particularly significant, becoming the main driving force for the expansion of the industry. In the Chinese market, with the acceleration of the localization process of integrated circuits and the rapid expansion of the new energy industry chain, the demand for deposition furnaces and related equipment has grown significantly. Especially against the backdrop of the expansion of wafer fabrication plants, the increase in photovoltaic cell production capacity, and the rise in investment in new material research and development, the domestic market size has continued to expand.

Iii. Current Technological Development Level The current deposition furnace technologies mainly include three categories: chemical vapor deposition (CVD), physical vapor deposition (PVD), and atomic layer deposition (ALD). Among them, ALD technology is increasingly widely used in advanced processes due to its extremely high film uniformity and atomic-level thickness control ability. CVD technology remains one of the most mature and widely applied processes in industry, especially dominating the deposition of materials such as polysilicon, silicon nitride, and silicon oxide. PVD technology, with its advantages of low-temperature processes and high-purity films, holds an important position in the fields of metal films and optical coating. Although ALD technology has a relatively high equipment cost and a slow deposition rate, it is irreplaceable in advanced processes of 7 nanometers and below and is gradually becoming a key technology in high-end chip manufacturing. From the perspective of equipment development, modern deposition furnaces are evolving towards high-precision control, intelligent management, and multi-process integration. For instance, by introducing plasma enhancement technologies (PECVD, PEALD), high-quality thin film deposition can be achieved at relatively low temperatures.

In addition, the introduction of artificial intelligence and industrial software will also drive the deposition process to shift from experience-driven to data-driven. To sum up, the deposition furnace industry is currently at a critical stage where technological upgrading and market expansion go hand in hand. Driven by the continuous growth of downstream high-end manufacturing demand, its market size is expected to further expand, and its technological level will also constantly move towards high precision, intelligence and integration.
