Metals Injection Molding (MIM)

Metal Injection Molding 

In today’s cost cutting economy, every manufacturer is looking for a way to reduce cost and streamline their business. In response, metal injection molding has emerged as a cost-effective way to manufacture high quality parts with increasingly complex geometries. The production process, similar to plastic injection molding, involves injecting a combination of powdered metal and a binding agent into a mold, followed by sending the component through two different furnaces (debinding and sintering) to remove the binding agent and produce the completed part. By controlling different aspects of the sintering and debinding furnace conditions such as gas selection, dew point, temperature and flow rate, the desired carbon concentration can be achieved. As a recognized green technology, metal injection molding has many advantages over other manufacturing processes by minimizing material waste without sacrificing mechanical properties or material selection.

Sintering Gas Atmospheres

For ferrous or non-ferrous metals, the use of nitrogen or hydrogen-based atmospheres can help you achieve the control and purity that are difficult to obtain with generated atmospheres. Nitrogen or hydrogen-based atmospheres help minimize the variations in atmosphere composition and dew point that are common with endothermic and dissociated ammonia atmospheres. Air Products has extensive experience in helping customers optimize their sintering atmospheres to improve their operations.

Nitrogen Supply Monitoring Systems

Our nitrogen supply monitoring system can help you improve process safety related to embrittlement of carbon steel components. The system monitors nitrogen supply parameters, such as storage tank level, pressure and nitrogen house-line temperature to provide operators with an alarm if the levels fall below desired settings.
