Metal powder injection molding (MIM) technology for vacuum sintering furnace requirements

Vacuum sintering furnace metal powder injection molding (MIM) technology has the ability of cost-effective operation of an important factor is the economic process gas and power consumption. Metal powder injection molding (MIM) technology has very strict requirements on the vacuum sintering furnace, the following by daihong new material xiaoqiao for several aspects to analyze in detail the requirements of metal powder injection molding (MIM) technology on the vacuum sintering furnace is what.

Depending on the type of gas, these two cost elements in the sintering process can account for 50% of the total cost. It is reflected in: in order to save gas consumption, should implement adjustable air pressure mode, while ensuring degreasing and sintering process from pollution; In order to reduce the power consumption, the heat loss is reduced by manufacturing the heating element optimized by metal powder injection molding technology. To achieve these design points and keep research and development costs within a reasonable range, a modern resource-efficient vacuum sintering furnace USES hydrodynamic calculation tools to find flow and heat flow patterns.

Depending on the weight of the sintered part and the amount of residual polymer, the metal powder injection molding technology binder will concentrate on the peripheral parts to varying degrees (such as exhaust pipe, pump and heat area), which will lead to long downtime for manual cleaning and daily maintenance. For example, if the net weight of the material reaches 400kg(> furnace volume, and the binder content is 3%~4%), the polymer as high as 3% will be removed in the degassing stage. Even so, most of the gases emitted by metal powder injection molding (>95%) should be collected at specific condensation points (such as binder collectors or wax separators). From this, big big new material discovers, because decontamination and manual cleanness work, door-to-door cycle time will increase more than 2 hours.

To sum up, daihom's new materials estimate that inefficient and poorly designed vacuum sintering furnaces will reduce operating performance by 15%. Therefore, metal powder injection molding technology manufacturers will consider more advanced equipment with automatic cycle cleaning system, to reduce maintenance work, so as to keep unexpected faults at a low level.

Fast-growing MIM industry leaders need to be able to flexibly plan their production capacity and respond quickly to changing market demands, but long lead times for metal powder injection molding technology production equipment will slow the company's growth. But daihom's new materials found that equipment manufacturers did not start production until orders were received, rather than pre-storing key components and materials in warehouses. When enterprises receive new urgent orders, the delivery date of new equipment of 9-12 months will be the bottleneck of metal powder injection molding technology production line. Therefore, vacuum furnace manufacturers introduced the concept of lean production and standardized production.

MIM experts found that vacuum sintering furnace metal powder injection molding technology key components about 60% of the metal powder injection molding technology production material is stainless steel, the common alloy is 17-4ph and austenitic stainless steel 304L and 316L. Ready-made injectable ingredients can cost anywhere from $30 to $50 per kg. After molding and degreasing, the original parts loaded into the furnace can be worth more than thousands of dollars. In this way, the reliability of key components of vacuum sintering furnace is very important.

Hot design and gas management system such as mentioned above, in peace soaking treatment temperature reaches ° C temperature rise, the residual polymer binder degassing process. In order to effectively transport gas materials to the outside of the hot zone, metal powder injection molding technology requires that there is a continuous homogenous purification air flow at each point in the box. The design of gas tight furnace (or muffle) can reduce the size of vacuum sintering furnace and realize external heating. The main advantage of the metal powder injection molding technology design is that the furnace provides a high purity atmosphere and ensures that the hot gas flows evenly through the parts. However, daihom's new material found it difficult to install a cooling fan in the furnace, which led to longer production cycles and higher investment, maintenance and energy costs for the furnace gallbladder.
