Have you already spent a lot of money on metal deck roll forming machine? Sometimes bought a device at a low price and went back. After running the roller for three months, it was polished. After listening to the publicity of “full automation”, the machine arrived in the workshop and found that it took a whole day to change the mold. In addition, the equipment shakes like a sieve when running. Party A directly refuses to accept the goods.
The root of these problems is not the product itself, but in the machine that produces it. If a metal deck roll forming machine leaves hidden dangers from the design stage, it can’t be adjusted back no matter how much it is adjusted later. Next, I have sorted out the problems that are likely to arise and the experience of finally choosing the right equipment.
I. The three most prone problems in the metal deck roll forming machine
The material of roller
In order to reduce costs, some manufacturers use ordinary tool steel or even cast iron for rolling rollers, and the surface is not chrome-plated or heat-treated. This kind of roller may not be able to see the problem on a thin plate of less than 0.8mm, but once it is on a galvanized sheet of more than 1.2mm, the roll forming point will wear out very quickly. After wear, the roller surface is no longer flat, and the rib height of the board begins to float, and the serious scratches are directly pressed on the board surface.
At present, the well-made metal deck roll forming machines are basically forged with GCr12MoV bearing steel, heat treated to HRC 58–62 and then chrome-plated on the surface. There is no problem in the normal use of this configuration for five to eight years.
The stability of the main frame
Some low-cost metal deck roll forming machine manufacturers use thin frames with poor rigidity. After several hours of continuous production, the frame will be slightly deformed. This amount of deformation is invisible to the naked eye, but the accuracy of the profile will drift with it – the board that comes out in the morning does not match the board in the afternoon. If the joints between the boards on the construction site are uneven, the construction party will complain.
The third is the shearing system.
The cheap downtime shear has to stop the whole line every time it is cut, and the production capacity cannot be up. What’s more, if the material of the blade is not good, it will be blunt when cutting thousands of knives, and the incision will begin to hang burrs. Construction workers on the construction site also have to use angle grinders to remove burrs, which is labor-consuming and time-consuming.A reliable metal deck roll forming machine should be equipped with a stable automatic cutting system, high-quality blades, and accurate cutting control to ensure smooth and clean finished products.
II. The most commonly overlooked details when overseas buyers choose equipment
When choosing a metal deck roll forming machine, many overseas buyers pay attention to the parameter table – how many times, how fast, how much power. Of course, these are important, but there are several details that are often ignored, and it is precisely these details that determine how long the equipment can last.
Brand level of electrical components. There may be no difference between using Schneider-level and using miscellaneous components at the beginning, but the difference in the failure rate will come out after one year. In particular, the stability of some brands of contactors and frequency converters varies greatly under high-load continuous operation.
Is the operation interface really easy to use? Some machines claim to be PLC to control the touch screen, but the interface logic is chaotic, the language translation is stiff, and the operation is difficult. A good control system should allow new operators to get started independently in two or three days, instead of staring at the full-screen parameters at a loss.
After-sales response speed. This is the most easily ignored point. A one-day downtime during the peak season of building board production is a loss of thousands of meters of production capacity. If the manufacturer’s spare parts inventory is insufficient, and a limit switch is broken, it will have to wait two weeks to ship. Who will bear the loss?
III. What is the difference between source factories and traders?
There is a common phenomenon in foreign trade procurement: the quotations of different channels may be 20% to 40% different for the same metal deck roll forming machine. Where is the price difference?
The difference is in the middle link. Traders increase the price on the basis of the factory price, and do not produce or do after-sales service. Once there is a problem with the equipment, traders often can only pass it on to the factory. The communication is long and the response is slow.
The source factory produces its own rollers, molds and main frame, which saves the intermediate price increase link, and the quotation is closer to the actual cost. More importantly, if there is a technical problem, you can directly connect with the engineer without talking through the middleman. Overseas buyers can go to the factory to see the operation of the metal deck roll forming machine on the spot, bring their own materials to the machine for testing, and confirm that the output is qualified before placing an order – this kind of transparency cannot be given by traders.
IV.HENER Machinery is a good choice for you
Speaking of the source factory, Cangzhou HENER Machinery has been in the field of roll forming machine for many years.
The core advantage of our metal deck roll forming machine is that the rollers, molds and main frame are all processed independently – not external assembly, but self-control from materials to finished products. This means that it can be more stable in terms of accuracy and consistency.
For overseas buyers, the more practical practice is to send your cross-section drawings and material specifications to HENER ’s engineers first. After getting the plan and quotation, you can come directly to Cangzhou to see the factory for testing if you have the conditions. Seeing the equipment running your own materials and the cross-section you want is more reliable than looking at any parameter table.
If you are looking for a reliable metal deck roll forming machine, or if you want to change the supplier of the equipment you bought in other places before, it is worth ten minutes to talk about HENER Machinery. Bring your cross-section drawings and capacity requirements, and the engineer will give you a one-on-one plan.
