In the process of forging metal, there are a variety of techniques
utilized, depending on the needs for the product designed and the
stage of product manufacturing. Often, forging is meant to shape the
metal; however, some techniques go beyond shaping. Precision forging
is more of a refinement process than a shaping process. When a
product is near completion, precision forging is done using existing
forging technology to refine the product to the point that little or
no further machining is needed before using the product for its
intended purpose. Usually, after the precision process, final
touches are done to the metal before either shipping or using the
product in another part of the manufacturing process.
There are various techniques used in precision forging to obtain the
final specifications required for the product. Such techniques often
revolve around close tolerance-forging with the objective of
eliminating waste commonly contributed by the post-forging process.
Results from the precision process usually form the metal to
tolerances that exceed industry standards, subsequently eliminating
the need to use additional machinery processes that creates wastage.
Reducing such wastage helps to achieve an overall savings for the
manufacturer, though not a savings on the particular product using
precision forging. Other savings include creating less scrap for
disposal through using less materials and using less energy
resources to complete the process.
Cost, however, is a major factor in precision forging, consisting of
both time factors and consumption of human capital to complete the
process. Performing precision forging often takes a lot of time and
expertise attending to detail of the product, which can
significantly increase the cost of the manufacturing process.
Additional tooling techniques are used, thereby typing up machinery
for longer periods that cannot be used elsewhere in the
manufacturing process. Therefore, precision techniques are typically
reserved for products with specifications of very high quality to
account for the additional manufacturing costs. Cases where a
significant savings in wastage can be achieved are another
consideration taken into account when deciding on the usage of
In addition to the actual precision forging techniques and methods
utilized, the process also accounts for additional improvements
applied to the product. Those improvements may include controlling
the temperature of the metal or pre-heating it. Additionally, the
process may involve the application of lubricants or decaling to
finish the precision process. Once the final touches are added, the
product is ready for use or for shipping.
