This question is asked by everyone who is faced with the need to modernize or launch a forging site. I’ll say right away: just look for a “Chinese manufacturer?” - this is the first and main pitfall. Because in China there is everything: from garage workshops that assemble presses from what they have, to factories whose engineers have been working on exactly this for decadeshydraulic presses for hot forging. The difference is in price, resource, accuracy and, most importantly, in understanding the hot stamping technology itself. Many people mistakenly believe that the main thing is tonnage, and everything else will follow. In practice, if you buy a powerful but incorrectly designed press, you can end up with problems with ejection, plate misalignment, or pressure instability in the most unexpected place in the process chain.
Yes, I know everyone is getting into it. And I went through this myself about seven years ago. Result? I received three dozen offers with a price range of four times. Most managers had difficulty understanding the difference between a hot forging press and, say, a chip briquetting press. Their keywords are “hydraulic press”, “high quality”, “delivery”. But you need the frame design to be designed for cyclic thermal loads, to have an effective cooling system for the rods and guides, to provide interfaces for automatic workpiece feeding and waste ejection. On Alibaba, this becomes clear on the third or fourth letter, and often after the advance payment has been made.
It is much more effective to look for not just a supplier, but an engineering company or a plant with its ownproduction line. Their websites often look more modest, but there are photographs of workshops, assembly, and load testing. Pay attention to the details: how the cylinders are attached, what is the design of the frame (all-welded or stacked?), what brands of pumps and hydraulic valves are used. If the site only has renderings and general phrases, this is a wake-up call.
At one time I came across the siteShandong Shenyang Mechanical Equipment Co.,Ltd(https://www.shengyangjxgroup.ru). What attracted me was that they position themselves as a high-tech enterprise, but at the same time, the product section contained not only beautiful pictures, but diagrams, equipment options, videos of presses in operation in customer workshops - you can see that the equipment is “in the field”. This is a different level of dialogue. Although, to be honest, at first I was skeptical - everything was described in too much detail, I thought maybe it was just a good copywriter who had worked.
Any manufacturer who is confident in their product will easily organize an online broadcast from the workshop or provide a recording of the tests. If they refuse or take their time, it means they have something to hide. What should you ask to see first?
Hydraulic systemassembled. Not just a tank and pumps on a frame, but work under pressure. It is important to see if there are any leaks on the flanges, how the high-pressure hoses behave under sudden loading, and how quickly and smoothly the spool operates. I once saw how on a 1600-ton press the entire structure was shaking at idle speed - it turned out that the manufacturer saved on dampers and a pulsation smoothing system.
Control system. Almost everything is CNC now, but the devil is in the details. The interface should be intuitive, and not require studying a thick manual in broken English. Pay attention to how the forging stages are programmed, and whether it is possible to integrate with robotic manipulators. UShandong ShenyangBy the way, in their high-end models they use Siemens touch panels with an interface localized in Russian - a small thing, but it saves weeks of setup.
Mechanical part- frame and slider. Here you need to look for traces of processing on the guides, the quality of the welds (they must be smooth, without cavities, and often undergo ultrasonic testing). If possible, ask to see how the slide is calibrated to be parallel to the plate - this is critical to uniform die wear and forging quality.
When a specific offer appears, for example, for a 2500-ton press for forging flanges, do not rush to rejoice at the low figure. The standard configuration rarely includes everything necessary: an oil thermal stabilization system, precision position sensors, a cabinet for local cooling, and a special tool for installation. All these ?options? can increase the final cost by 25-40%. A detailed specification with the make and model of all major components should be required.
Logistics are a different story. Sea delivery is long, but cheap. However, consider the cost of port services, customs clearance and, most importantly, delivery from the port to your workshop. The press is oversized and often requires traffic police escort. It is better if the contract stipulates the FOB condition with the subsequent organization of delivery by a trusted forwarder, who may have to be sought separately. Some manufacturers like the sameShandong Shenyang Mechanical Equipment Co.,Ltd, offer a turnkey service, including delivery, installation and commissioning. It's more expensive, but it saves a lot of headaches, especially if you don't have your own experienced hydraulic mechanic.
And the main stone is warranty and service. 12 month warranty is standard. But what does it cover? Is it just a manufacturing defect or also wear of the seals in the first months of operation? How is service support organized? Are there engineers who speak Russian? Where and how quickly can I get spare parts? It is ideal if the manufacturer has a representative office or a spare parts warehouse in your region. The mentioned company, judging by their website, is developing this network in the CIS, which is a serious argument in their favor.
I'll tell you about my first order. I was looking for an 800 ton press for artistic forging. I found the manufacturer through an intermediary in Harbin. The price was attractive. As a result, we got a machine that seemed to work, but... The control system was so primitive that it was necessary to literally adjust the pressing speed at the end of the stroke “by eye,” which affected the accuracy. The hydraulics got so hot that after two hours of continuous operation they had to stop. It turned out that the manufacturer supplied a smaller tank and a weak heat exchanger. We finalized everything ourselves, with the involvement of local specialists. The cost of modifications was almost equal to the price of the press.
After that I began to approach things differently. I made requests as detailed as possible, with technical specifications, where I specified not only the main parameters (force, stroke, dimensions), but also the requirements for noise, energy consumption, and positioning accuracy. And he demanded that each point in the technical specification be answered in the commercial proposal. This eliminated 80% of non-professional players.
The second order was already more successful. He worked directly with a plant in Jinan, which specialized in forging and pressing equipment. We talked for a long time, even showing similar projects on Skype. The press was shipped, delivered, and installed under their leadership. It has been working for the fifth year without serious complaints. This experience confirmed a simple truth:hydraulic press manufactureryou need to look not by price, but by competence in a specific area - hot forging.
So, to summarize my sometimes bitter experience. First, clearly formulate the technical specifications. What will you forge? What kind of accuracy and performance are needed? Second, look not on general sites, but through industry catalogs, recommendations from colleagues, and study the websites of factories. Pay attention to companies such asShandong Shenyang, which focus on manufacturability and have detailed information. Third, negotiate in technical language, demand evidence in the form of photos, videos, test reports. Fourth - do not skimp on logistics and installation; it is better to include this in the contract with the manufacturer. And fifth, think about the issue of spare parts and service in advance.
Finding a good manufacturer in China is possible. But this is not a quick catalog search, but rather the work of a purchasing technologist who must understand the subject no worse, and sometimes better, than the seller. Good luck. And yes, if you find a worthwhile option, if possible, go to the reception. There is no substitute for a personal inspection.
