Figure 1. The quality of design is critical to the successful
production of quality MIM components. AMT uses CAD
technology to work with its customers, optimizing
their concepts for manufacturability. For example,
since brown MIM parts have a sintering shrinkage
factor of 15 to 20 percent, shrinkage must be calculated
into the mold dimensions at the earliest possible stages
of a new project. CAD also helps AMT keep its first part
lead times to within six to eight weeks.

Figure 2. AMT presently operates five Arburg molding machines.
AMT's dedication to quality is exemplified by the fact that
its QC engineers setup the machines for running parts.
Plans call for possibly adding two more molding machines.
Such capacity expansions maybe necessary to meet growing
customer demands.

Figure 3. AMT uses seven custom-built furnaces for thermal
debinding of its feedstocks,which are all compounded in-house.
Proprietary, patented technologies in its thermal debinding
furnaces help thecompany in its carbon control efforts to
reduce the brittleness of finished products. They also help
it maintain itszero defects/million record.

Figure 4 & 5 (above and below). Sintering at AMT is carried out
in high-temperature vacuum furnaces. The company uses the
same setters for debinding and sintering to minimize any possible
handling defects. Though batch furnaces like this one are being
used, AMT is considering installation of continuous furnace
capacity for high-volume parts production of longer runs.

Figure 6. In addition to its impressive arsenal of metrology,
metallurgy, and chemical testing equipment, AMT also has
various types of inspection fixtures and gauges. Many have
been designed in-house. Every department in the company,
including molding, works together to ensure customers
receive the best possible quality, delivery, and price for their
production projects.
