Products are widely used in petrochemical industry, engineering machinery, auto parts, locomotive and railway parts, metallurgy, shipbuilding, military products and other fields.

Mold development process
The R&D team conducts CAD design, CAM, UG, SOLIDWORKS modeling work.
We use superfine die steels as the raw material, allowing them to be processed with a CNC center, ensuring that the die steel’s precision is ensured and has excellent fatigue resistance, abrasive resistance, making sure that the forgings are produced in high quality.
There are more than 2000 sets of molds here at our company. The customers can choose any of them for processing to minimize cost. We perform inventory taking, clearing and recording every week to ensure that the production proceeds as scheduled.
Our mold warehouse is managed by following the IATF16949 quality management system and “6S lean management”, giving a long service life to the mold and making it convenient for use and storage.

Design and manufacturing
We will design and manufacture forging molds on receipt of the customer’s drawings or samples, then we will manufacture the mold by following the mold design. The molds often include forging dies, trimming dies.
Steel billet cutting and heating
Often, we will prepare the frequently used material in stock featuring material No. of 20＃, 35＃, 45＃, 20Cr, 40Cr, 20CrMnTi, 20CrMo, 30CrMo, 35CrMo, 42CrMo, Q235, Q345, A105 etc. Then an intermediate frequency furnace will be used for heating the raw materials into certain temperature and finally putting the eating rod on the metal framework for forging.
Forging
Before metal forging process starts, the top and bottom dies shall be connected to anvil block of forging press. Then the workers will pick the metal materials and put them between the forging dies to achieve desired shape by pressing the metal materials several times with a high-speed.
Cleaning
After the forging completed, there will be unwanted burrs around the forged blanks, so removing the burrs is a necessary step. Which requires the workers to mount the trimming dies under the punching press, then pressing the forged blanks to clean burrs on the surface of the forgings.
Heat treatment
Heat treatment process helps to get the required mechanical performance and hardness of products. The heat treatment techniques cover normalizing, quenching, annealing, tempering, hardening and so on.
Shot blasting
After shot blasting process, the forgings will have a smoother and cleaner surface than it would have been. Usually the surface smoothness of the forgings is available in Ra6.3, which is even smoother than that of the lost-wax casting.
Processing
For some components, the forging process is not available in the required tolerance, under this case, processing is optional. We will conduct the product processing with different processing equipment, including milling machine, boring machine, drill press, grinding machine, numerical control machine etc.
Surface treatment
In most cases, if no specific requirements required, we will have water/oil rust protection treatment on the surface of the forgings. We can also conduct other surface treatments, including paint spraying, powder coating, electroplating, electrocoating to meet specific needs of our customers.
Final examination
We will have an inspection on the product size to ensure high quality of our products.Sometimes, we also have mechanical performance and chemical components testing on our products.
Package and delivery
In most cases, the forged components will be packaged in polyethylene bags and then being put into firm wooden boxes. We are also able to customize packages according to the customer’s needs. As we are located in Ruian forgings industrial park, we have easy access to raw materials supply, which is cost effective on the whole.
