Free forging

Definition of free forging Free forging is the use of impact force or pressure on the metal between the top and bottom of the anvil free form in all directions, without any restrictions to obtain the desired shape, size and certain mechanical properties of the forging method.

Free forging equipment

The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The hammer used in production is air hammer and steam air hammer. Hydraulic press is the only way to produce large forgings by using static pressure generated by liquid to deform the blank.

Basic process of free forging

Rough upsetting is a forging process which makes the cross section of billet larger and the height smaller. There are two kinds of upsetting: integral upsetting and partial upsetting. Drawing and drawing is the opposite of upsetting. It is a forging process to increase the length of the billet and reduce the cross section. The punching process of punching holes or blind holes on billets is called punching. The characteristics of free forging and the application of free forging depend on manual operation to control the shape and size of forgings. Therefore, the forgings have low precision, large machining allowance, high labor intensity and low productivity. Therefore, it is mainly used in single-piece and small-batch production with simple structure and shape of forgings.

      ADVANCE AUTO PARTS OFFERING STUDENTS A CHANCE TO WIN A ‘FUEL RIDE TO COLLEGE’ AND FREE ‘OFF-TO-CAMPUS’ IN-STORE SERVICES
        Incoming college freshmen can enter to win a “fuel ride” – four years of free gasoline – after new national survey reveals gas is a significant financial strain for majority of students
      RALEIGH, N.C.--(BUSINESS WIRE)-- Advance Auto Parts (NYSE: AAP), a leading automotive aftermarket parts provider, announced today that it will help advance the education of incoming college freshmen, and ease their financial burden, by awarding 10 “fuel rides” in the form of four years of free gasoline to 10 lucky winners of the “Fuel Ride to College” sweepstakes.*
      This press release features multimedia. View the full release here: 
      link hidden, please login to view Along with providing four years of free gas to 10 college students, Advance Auto Parts is offering free in-store services, including free battery testing and installation, wiper blade installation and check engine light scanning. (Photo: Business Wire)
      Advance’s “Fuel Ride to College” sweepstakes arrives right on time as prices at the pump tick up. New data from Atomik Research reveals that 67% of college students cite gasoline for their automobile as being an expense that puts the most financial strain on their wallet**, while 76% of parents of incoming freshmen say they are worried about their student’s ability to afford gas.***
      Parents also have significant anxiety regarding the safety of their college students when it comes to the automobiles they operate, according to Atomik Research surveys commissioned by Advance. Nearly two-thirds (63%) of parents of incoming college freshmen feel very or extremely anxious about their student’s safety when it comes to maintaining their cars and about three-fourths (73%) of parents have more anxiety about the car safety of their incoming college freshman than they did during the child’s senior year in high school.
      Parents’ anxiety is warranted as more than half of college students admit to having ignored dashboard alerts and notifications, including “check engine” and “low battery warning,” according to the survey.
      To help ease this anxiety, Advance and its team of friendly automotive experts are offering students and their parents free “off-to-campus” in-store services at Advance stores nationwide, including free battery testing and installation, wiper blade installation and check engine light scanning.
      In addition to awarding 10 four-year “Fuel Rides to College,” Advance will also award 20 additional winners a $100 Advance gift card to stock up on essentials to help keep their automobiles in reliable shape this school year. If interested in learning more, visit

      Additional data from the Atomik surveys validate the value of a “Fuel Ride to College:”
      One-third (33%) of students cite that a lack of gas money or the cost of gas has deterred them from going to class, the library or study groups, while 60% of incoming college students’ parents express this exact worry: that the cost of gas will deter their child from going to class or education-related activities. Many college students choose between fueling their body and their automobile: more than one-third (36%) say they have compromised or cut back on groceries to fit gas money into their budget. One-quarter (25%) of college students say they’ve had to cut back or compromise school supplies to fuel their automobiles. Advance has also partnered with auto racing driver and television personality Arie Luyendyk Jr. to encourage incoming freshmen to enter for a chance to win a “Fuel Ride to College” and spread the word about Advance’s commitment to providing parents peace of mind via complimentary in-store services.
