PVC card printing machines are now the most important tool for making game cards, gaming cards, anime cards, and other smart cards. This is because the printing and packaging industry is shifting towards a "short, flat, fast" model. Printing companies in India and around the world need their machines to be stable so that they can fulfill orders and reduce costs. If there is no scientific maintenance system, the production of PVC materials will generate a large amount of dust, which will put a lot of pressure on the molds, reducing their accuracy and making them more susceptible to damage. This article will provide a detailed introduction to the daily maintenance tasks and troubleshooting methods of PVC punching machines from the perspective of workshop technical management. This will help your machine maintain a 'new machine state' for a long time. As a company specializing in customizing small batches and a variety of different products, we know that the only way to achieve optimal performance when handling tasks ranging from bank cards to small packaging boxes is to adjust the equipment to its optimal state.
The die is the most important component of the PVC card punching machine. Its working effect depends on its maintenance level and whether there are burrs on the edges of the card. If you punch a lot of game cards or star cards, the die will wear out on its own because it keeps hitting them. Based on my observations in the industry, high-quality molds can typically use over 2 million punches when used with PVC materials. But this does not mean that maintenance is not required during this period. It is best to use a soft-bristled brush to clean PVC debris and paper bristles in the gaps between the cutting dies after each production shift. This is because these impurities will adhere to the blades, making the passivation process faster. The recommended criteria for replacing molds are not only based on how many times they have been used. This also depends on the appearance of the edges of the finished product. If there are small white edges or more burrs on the edge of the card and no pressure factor is considered, it means that the cutting edge has reached the replacement or grinding cycle.
Replacing the mold is much easier because it is too light. We make the mold structure easier to disassemble because the printing industry is currently facing the problem of "short delivery time." Replacing the mold only takes 2-3 minutes. This means that the device can quickly change anime card orders to poker card orders without the need for heavy tools or complex adjustments. To ensure that the pressure distribution remains unchanged after each mold change, we use a precise mold guidance system. This is much better than the tedious process of recalibrating gaskets on old devices. It converts idle time into useful production capacity.
You need to check three main systems every day to ensure that the PVC card punching machine can maintain its high level of "gradually precise feeding" even after long-term high-speed use. Firstly, let's talk about the main motor and servo system: This machine has a built-in 7.5 kW servo power supply system that provides cutting force. Before turning on the servo drive every day, check for any alarm codes and listen for any strange whistling sounds. It is important to ensure that the cooling fans on the servo motor are working properly so that they do not overheat or have incorrect positioning. This is because the servo motor depends on the feedback position of the encoder. This is crucial for ensuring that the final product is placed in the correct position.
The next part is the system for sending and receiving messages. Only when the guide rail is very hard can the equipment maintain accuracy for a long time. After every 200 hours of use, the dirt and dust on the surface of the guide rail should be removed, and special oil for the guide rail should be added. If the lubrication of the guide rail is insufficient, it will "lag" or crawl when you feed it step by step. This will directly impair the layout's ability to visually correct and locate things. There is also a pneumatic system. If the pneumatic components have an automatic feeding device, it is necessary to discharge the water collected in the air filter every day. The cylinder sealing ring may be damaged by moist compressed air, resulting in unstable air pressure. In mild cases, it can lead to improper collection, and in severe cases, it can result in weak cutting force. To ensure that the air pressure remains constant, it is best to mark the pressure range (usually 0.6-0.8 MPa) at the gas source processing unit three. This is necessary for the automatic collection and processing functions to function properly.
You hope to maintain the stability of the production process and save money on new equipment by extending the service life of the PVC punching machine. When they receive many small batch orders, many Indian customers frequently turn on and off the machines. If you don't pay attention to it, it may lose accuracy within three to five years. Rather than 'after repair,' it is more like 'preventive maintenance.' You must clean up the remaining PVC fragments on the counter after work every day. If these fragments get stuck on moving parts, it's like applying grinding paste on worn mechanical mating surfaces. The machines in the printing workshop do not like dust and paper powder in the air. Regularly cleaning the filter of the cooling fan in the electrical control cabinet can help prevent short circuits in electrical components.
Secondly, the software and hardware design of the device needs to fully utilize redundancy. The progressive feed and visual correction system on this device enable it to handle many different materials, such as paper, film, and soft magnetic film. But you need to change the stamping pressure according to the thickness and hardness of the new material. Don't let the machine run at its limit for too long just to complete the work faster. When switching back to regular paper cards after stamping hard materials such as bank card substrates, it is best to lower the pressure setting to protect the crankshaft and bearings. You should also regularly check the levelness of the equipment. If the machine shakes more, not only will the accuracy decrease, but it will also loosen bolts and damage the structure. If you take good care of a machine, its mold can last for over 2 million cycles, and its body can last for decades.
When the PVC card punching machine starts to malfunction, quick troubleshooting can help prevent significant financial losses in actual production. Here are the best ways to solve the three most common problems:
If you hear strange noises coming from the device, the first thing you should do is turn off and unplug the power. Strange noises are usually caused by mechanical damage or insufficient lubrication. Step 1: Check if there are any remaining cards or debris in the mold cavity. This is the most common reason for 'lag.' Step 2: Manually rotate each transmission node and see how difficult it is to rotate. If the turning gear is heavy and occasionally makes noise, it may be due to wear on the crankshaft connecting rod bearings or guide rail sliders. If you hear sharp friction sounds, it may indicate that the feeding belt is loose or the guide rail does not have enough oil. If there is a delay, do not attempt to start the 7.5 kW servo drive module. This may harm it.
The most annoying problem is that the game cards or business cards punched out will move around. The machine does not need to wear out. Firstly, ensure that dust does not obstruct the lens of the visual correction system, as this may cause it to malfunction. Secondly, check if the distance between the feeding steps remains constant. If the material does not have sufficient grip and sliding properties, it will make more mistakes in the "gradual" feeding process. Thirdly, ensure that the screws securing the molds together are tightened. Replacing the mold only takes 2-3 minutes, but excessive frequency can result in insufficient torque for the locking screws. Even small changes in the mold can cause uneven cutting edges.
Most of the time, this is due to pressure and the working mode of the cutting mold. Firstly, check if there are any waste blockages inside the cutting mold. This will prevent new materials from being washed away. Secondly, if there is no blockage and the cutting power (current) display of the machine is normal, it means that the cutting edge has worn out and grinding needs to be arranged immediately. For orders that do not require burrs, such as high-quality star cards, it is best to perform preventive grinding at 80% of the mold life. This will ensure that all edges of the product are smooth and free of burrs.
Simply put, the printing workshop is running well because the PVC card punching machine is working well. The data-driven management makes it easy for us to see the importance of maintenance: Strict daily maintenance can keep the mold life above 2 million times; Regular cleaning and lubrication can maintain cutting accuracy within ± 0.05 mm for a long time; With our unique lightweight mold design (mold replacement only takes 2-3 minutes), we can significantly reduce order switching time and truly respond quickly to small batch orders. If you want to make poker cards that need to be sorted and collected in some way or want to get the best burr-free anime cards, this guide will help you keep your device at the top of the "short, flat, fast" list in a fiercely competitive market.
