Processing
Molding
R feedstocks have excellent moldability for producing complex parts. At the typical molding temperature of about 350 0 F (177 0 C) the feedstock has the consistency of toothpaste and can be molded easily using a low mold temperature of only about 110 0 F (43 0 C). Benefits of low mold temperature include faster mold changes, lower heating cost and use of less expensive water heating system.
- The molded parts have excellent part-to-part consistency of weight and good green strength to permit handling for further processing.
- Runners and as-molded (green) scrap, if any, can be readily recycled many times - an important factor for cost-effective production of small, complex MIM parts.
Debinding and Sintering
- The most common debinding method used with our products is thermal debinding; however, first stage solvent debinding can also be used. Debinding of parts molded from ADVAMET
R feedstock does not require any acid catalysts.
- The binders are of the hydrocarbon variety so that there are normally no special requirements for disposal of products of debinding.
- Thermal cycles for debinding and sintering depend on such factors as material, part shape and size, type of equipment, part loading and the atmosphere.
- Ovens and furnaces commonly used in the MIM industry are suitable for debinding and sintering of parts made from our feedstock.
