Production Process
Production Process

1.Sliding wire feeding

Cut the steel ingot into reasonable sizes and weights according to product requirements

2.Heating(including tempering)

The heating equipment mainly consists of single chamber furnaces,push rod furnaces,and desktop annealing furnaces.All heating furnaces use natural gas as fuel.The heating temperature of steel ingots is generally between 1150ºCand 1240ºC,and the heating time of cold steel ingots is about 1-5 hours.The heating time of hot steel ingots,and the heated steel ingots enter the forging process.

3.Forging

The steel ingot is heated to around 1150-1240ºC and taken out of the heating furnace.Then,it is placed into an air hammer or an electro-hydraulic hammer by the operator.According to the size and forging ratio requirements of the steel ingot,corresponding processes such as pier thickness and elongation are carried out,and the size of the forging is monitored in real-time. The forging temperature is controlled by an infrared thermometer.

4.Inspection

Conduct preliminary inspection on the forging blank,mainly focusing on the inspection of appearance and size.In terms of appearance,the main inspection is to check whether there are cracks and other defects.In terms of size,it is necessary to ensure that the blank allowance is within the range required by the drawings and deep records

5.Heat treatment

A comprehensive process of heating a forging to a predetermined temperature,holding it for a certain period of time,and then cooling it at a predetermined speed to improve the internal structure and properties of the forging.Its purpose is to eliminate internal stress,prevent deformation during mechanical processing,and adjust the hardness to make the forging easier to cut.After heat treatment,the steel ingot is subjected to air cooling,and quenching treatment according to the material requirements.

We can produce different kinds of surface treatment after forging, such as machining, polishing, and plating.
We quote and produce the parts according to the drawings or samples from our customers. So if you are interested in our products and our company, please email us directly.
