Advantages of Forge Parts from Martin Tool and Forge

Benefits of Forgings

The forging process enables production of parts with high impact strength and structural integrity. The consistency of material and dimensions from the first part to the last and from one batch to another is extremely high. This insures more consistent end results after secondary operations. Higher strength to weight ratios reduce both weight and size when close fit or weight issues are a factor.

Forging can produce complex shapes that otherwise may require multiple manufacturing processes. Forged parts are compatible with most secondary operations such as heat treating, machining and fabrication. In many cases one forged part can be created where multiple parts were originally used, reducing labor cost.

Casting

• Stronger

• Preworking refines defects

• More reliable, lower cost over

component life

• Better response to heat treatment

• Adaptable to demand

Welding / Fabricating

• Material savings, production economies

• Stronger

• Cost-effective design/inspection

• More consistent and better metallurgical properties

• Simplified production

Machining

• Broader size range of desired material grades

• Grain flow provides higher strength

• More economical use of material

Yields lower scrap

• Requires fewer secondary operations

Powdered Metal

• Stronger

• Higher integrity

• Requires fewer secondary operations

• Greater design flexibility

• Less costly materials

Composites / Plastics

• Less costly materials

• Established documentation

• Broader service-temperature range

• More reliable service performance

Application: Counter weight on unit handling equipment.

Problem: Parts were being milled in-house from purchased burned plate. Process was expensive, but low volumes had prevented consideration of alternate methods of manufacture.

Solution: Instead of utilizing their expensive CNC milling equipment on relatively low-tech parts, Martin designed a simple die for a forged part, which worked well for medium quantity production runs. When compared to sourcing costs, production time, and scrap, the forged part was less expensive than the milled part. The real savings has resulted from the enhanced utilization of the CNC milling equipment for other, more profitable work.
