Conventional Horizontal Upset Forging methods are used to gather and displace metal to the desired form or profile. Normally products and components are forged from round stock materials and are heated using Induction Heating.
Upset Forging, or “heading”, is the process of increasing the parent material diameter by controlling the volume of gather using dies (tools), ensuring sufficient material is headed to produce a given profile or shape.
Typically components manufactured by forging have significant strength and a uniform material structure.
• Headed bolt blanks: hexagon, round head, flat profile
• Anchor pins
• Ground spikes, tent pegs & marquee stakes
• Anvil bolts
• Bespoke items
This unique forging process allows the gather of material to be far greater than conventional methods. The material is heated and formed using resistance heating and hydraulic pressure. The combined effect can create a large gathered ball or cone shape which can be further formed in dies on Vertical Presses to produce a component with a large head profile or shape, with a relatively small parent bar. Strength and structure characteristics are superior.
• Headed bolt blanks: hexagon, round head,
flat profile, tee & offset profiles
• Eyebolts: cylindrical and flattened
• Flattened head tee bolts
• Gear lever
• Hand tools
• Bespoke items
Preforms from Horizontal or Electrical Upset Forging can be finished forged using Vertical Forging presses. Also, direct forging from common stock materials (which do not need to be preformed or gathered) can be forged. Products to be forged can be heated and forged in dies (tooling) into a variety of shapes and profiles. The ability to combine the activities and processes enables Multi-Stroke to offer custom and specialised products, with the potential of reducing the material required to manufacture when compared with other forging processes and machining from solid bar stock.
