Applicability of Different Vacuum Sintering Furnace
Apr 18,2023
Vacuum sintering furnace does not consider customized highly specialized system, most of the sintering path on the market can be divided into periodic vacuum path and continuous atmosphere. The brown parts after injection molding and catalysis/degreasing contain residual polymer, and both furnaces provide a scheme for thermal removal of polymer. Next, let me introduce to you the applicability of different vacuum sintering furnace types!
On the other hand, if the vacuum sintering circuit is a relatively large part that is completely consistent in mass production or similar in shape, the continuous atmosphere circuit is fully utilized. In this case, the cycle is short, the sintering capacity is high, and a favorable cost-benefit ratio can be obtained. However, in small and medium-sized production lines, the annual output is 150-200 tons, the input cost is high, and the continuous atmosphere of large volume is not economical. In addition, the continuous atmosphere requires longer maintenance downtime, reducing production flexibility.
On the contrary, the periodic vacuum sintering furnace has obvious degreasing sintering process control technology. The above limitations (including the geometric deformation and chemical decomposition of the finished vacuum sintered road part) can be effectively solved. One solution is to float the binder material volatilized by the laminar process gas through a gas control system. In addition, by reducing the hot zone capacity, the temperature uniformity of the vacuum furnace is very good, which can reach lK. Generally speaking, the vacuum furnace's good atmosphere cleanliness, process parameter adjustment and small part vibration have become the technical choice for the production of high-quality parts such as medical equipment. Many companies face fluctuating orders and need to produce parts of different shapes and materials, and the low input and high cycle flexibility of the vacuum sintering circuit will create favorable conditions for them. Running the vacuum furnace suit can not only provide idle production lines, but also run other process programs at the same time.
However, some specialty vacuum sintering with these technical advantages is limited to a smaller usable capacity. The disadvantage of input/output ratio and low energy utilization can offset the cost savings of part sintering cost at different vacuum sintering process stages. Vacuum sintering furnaces have one of the important factors for operating capacity is economical process gas and electricity consumption. Depending on the type of gas, the two main cost factors of the sintering process may account for 50% of the total cost. In order to save gas consumption, while protecting the degreasing and sintering process from pollution, the adjustable gas flow partial pressure mode is implemented. In order to reduce power consumption, heat zones are created using optimized heating components, thereby reducing heat loss.
