Anyang Forging Press in the USA sanctioned list
Stay away from the war and refuse to be a partner of war criminals.sanctioned list
Anyang Forging Press is one of the big forging machinery manufacturers in China. they sell forging machines to Rassia’s military-industrial to help produce weapons for the Ukraine war. The American government had verified it and listed this company in the sanctioned list.
This company supplied hundreds of blacksmithing power hammers and hydraulic presses to Anyang USA, The company did not allow the sale of any goods to the American market in the following time. That means Anyang ST will be the only supplier of Anyang power hammers and hydraulic press. in the future.
How to break in your power hammer
Tips for Breaking-in Power Hammer
Dear ANYANG ST Hammer buyers：
Congratulations to you get a Brand new Anyang ST Power hammer. To keep you power hammer has a better performance in the following days, Some tips must be fulfilled during the breaking-in period.
1. Grease the moderate lubricating oil with the correct grade
1.1 Choose the suitable lubricating oil
5W-40 or 5W-30 lubricating oil is recommended, 5W-20 or 5W-10 lubrication oil is recommend when the temperature below -10 degrees, to ensure the oil has good fluidity when the hammer is working. Since the hammer working temperature is about 70 degrees, the frequency is 200-300 times, which is much lower compared with the requirements for lubricating oil of automobile engines.
1.2 Lubricating oil volume
Please add the lubricating oil volume between the two oil gauges as shown in the figure below, And please pay attention to the volume of lubricating oil and replenish it in time.
- Suitable Lubricating oil supply
Breaking-in period is defined as 8-10 hours. The oil supply can be accurately controlled by adjusting the needle valve on the pipeline, and the oil droplets glass cover above the oil pump can be observed to determine the oil supply. During the breaking-in period, the oil volume should be adjusted to 2-3 seconds per drop to ensure the oil film or even black oil dripping can be clearly seen on the hammer ram. This is a normal phenomenon of the internal cleaning of the new machine. After the breaking-in period, it is recommended to adjust the amount of oil to 7-8 seconds per drop (oil with different viscosity can be adjusted appropriately).
- Breaking-in period operation
First, ensure that the electrical connection is reliable, the pointer is at the hammer lifting position during working, plug in, adjust the needle valve, and keep hammer run unloading for 3-5 minutes to observe whether the lubricant can be sucked into the machine.
Then, lightly step on the pedal to move the hammer rod up and down so that the lubricating oil would blown into the front cylinder by the air. During the breaking-in period, will not recommend to do heavy forging work. better to forging some small and exquisite work-piece, just keep the hammer on working. And pay attention to the oil volume in the oiler to ensure it is in a reasonable range.

why Anyang st hammer hit energy heavier than others.
The hit energy (P) figures are a mathematical representation that was arrived at by comparing the speed（V）and weight of the ram(M), P=1/2*M*V². Besides that Anvil weight also is very important for forging efficiency, because it will decide how much energy losing when forging. that’s why a hammer of a given size will forge with more force against a heavier anvil compared with a hammer that has a lighter anvil.
- Anyang ST increases anvil weight. Anyang ST hammer became thicker and thicker, ST power hammer is one piece casting hammer that anvil together with the frame, so it will bring anvil weight heavier and heavier, then will help reduce hit energy losing.
- Anyang ST tries to make the stroke longer and longer, it not only can allow big bars but also can supply enough glide distance to make the top die get higher speed when forging, the speed (V) is one very important item for hit energy. Anyang ST hammers hit harder than other hammers.
- Anyang ST improves the finish of the machined surface, it will reduce friction that makes the ram move more quickly and reduce running temperature.
- Anyang ST hammer frame is casting, the overall rigidity will better than a fabricated self-contained hammer(over 20-30%) or mechanical hammer or the same weight(over 2-3 times).
