The ordering methods for global printing and business card printing are undergoing significant changes, especially in fast-paced markets like India. They have produced many similar game cards, but they have also made customized game cards (TCG), star cards, and small batch smart cards with many choices. This trend makes it very important for production equipment to adapt. Today’s PVC card punching machine is not just a simple punching tool; It is a fully processed platform with visual positioning, precision servo drive, and modular design. This article will show you how the PVC card punching machine uses precise adjustment technology to manufacture “short, flat, and fast” products when the material changes from 0.2mm thick cards to 1.5mm thick cards. This completely solves the technical problem encountered by printing companies when they have to fill out mixed orders.
Indian printing factories have found that PVC card punching machines that can quickly replace orders are their best competitive advantage. These machines help them reduce costs and complete tasks quickly. People often use this machine to make small boxes, bank cards, game cards, anime cards, and other things. Its main advantage is that it is suitable for paper PVC and other materials such as soft magnetic sheets, which can be physically modified to maintain a very low scrap rate, and even with large thickness variations, the edges are always perfect.
Setting of PVC card punching machine for cutting and stamping 0.2 to 1.5 millimeters thick
PVC of different thicknesses has very different physical properties. 0.2mm thick cards, such as disposable game cards or tickets, are very soft and easy to bend. It is difficult to penetrate cards that are 1.5 millimeters thick, such as high-end bank cards or identification cards. Firstly, you need to create a scientific database of material parameter correspondences so that the same PVC card punching machine is suitable for everyone. The operator must set the feed step distance and die-cutting pressure curve on the HMI (human-machine interface) of the equipment based on the weight and thickness of the material. Due to the extremely hard material, the visual correction positioning system requires the use of hyperspectral recognition mode for thick cards. In this way, even if there are small burrs on the edges of the material, the CCD camera can still accurately capture the positioning cursor and achieve a registration accuracy of ± 0.1mm.
Reducing tension feed is key in some cases for thin materials with a thickness between 0.2 and 0.4 millimeters. The imported ball screw is driven by a servo motor and adopts step-by-step precise feed technology. Each feeding action has micrometer level control, which can control its speed to prevent thin materials from stretching and deforming due to inertia. Stable speed cutting “is the main focus of materials with a thickness of 0.8 to 1.5 millimeters. The servo power of the punch press is 7.5KW, which is very powerful. This can prevent it from shaking when passing through hard materials at a stable speed. This can prevent the material from breaking or separating at the edges due to excessive impact force. You need to set this thickness based setting to fully utilize the PVC card punching machine.
How to adjust the pressure and stroke of a thick PVC card punching machine
The most common quality issue when stamping thick PVC cards is insufficient cutting, which can cause the edges to turn white or have burrs. This is because traditional mechanical linkage stamping cannot change in real-time based on force feedback. Servo direct drive or hydraulic servo hybrid drive technology is used for modern high-performance PVC card punching machines. You can change the stroke and pressure of the punch during flight. When stamping cards with a thickness of 1.5mm, use “segmented strokes” to make correct adjustments. Firstly, quickly move down to the surface of the material. Then, slow down the cutting to ensure that the cutting edge enters the material at a stable and correct speed. Finally, lift and unload a bit to prevent the mold from sticking to the material.
You need to combine the status of the mold with pressure control. Replacing the molds only takes 2 to 3 minutes because they are made of lightweight wood. But wooden molds are not as sturdy as steel molds. So, when you change the cutting pressure of the thick card, you should not only choose the highest tonnage. You should use the “micro range interference compensation” function on the device. Firstly, the operator should calculate a theoretical pressure value, which is typically based on the material’s shear strength and perimeter. Then, they should try boxing. Please check the cut portion on the card. If there are small burrs, either slow down the stamping speed or slightly increase the pressure. If the cross-section collapses, you should check the mold pad or change the lower limit of the stroke. These settings can be saved using advanced PVC punching machines. The next time you make the same thick card, you just need to call the formula and the machine will automatically use the settings without any additional debugging.
Optimization of Thin Card Bending and PVC Card Punching Machine
Printing thin cards has always been difficult, especially when they are very soft, such as game cards or playing cards that are only 0.2 millimeters thick. These cards are prone to wrinkling or deformation. We cannot just change the pressure to solve this problem. We should start with the “grip” and “traction” systems of the equipment. The ‘fully controlled’ material path is the most important part of the PVC card punching machine, enabling it to handle thin cards best. This device has an intuitive method of fixing and positioning the layout. Before the thin card enters the die-cutting station, use several sets of lightweight pressure rollers or vacuum suction tables to grind it flat and remove wrinkles caused by stress release.
The best way to improve is to make the process of handling waste and collecting finished products better. Thin cards are easily bent, so blowing air or falling from a high place will immediately cause them to bend. Therefore, the PVC card punching machine used for thin cards has an unloading method of “ejection+suction”, and there is a classification collection device at the end of the collection of finished products. For example, the device can collect thin cards that are easily stuck together in classification mode. To prevent the stacking, compression, or deformation of perforated thin cards, they can be sent to different card receiving slots on separate conveyor belts. This design ensures that the PVC card punching machine has a smooth and burr free stamping surface when used for stamping thin cards. It can also ensure that the stacked and collected cards are smooth and new.
The scheme of sharing one punching machine for cards of different thicknesses
Printing companies operating around the world, especially those that receive large quantities of small batch orders from India, have stated that the ability to quickly switch between orders of different thicknesses makes their equipment value for money. The PVC card punching machine requires three main hardware components to smoothly switch from 0.2mm to 1.5mm: modular mold system, digital parameter preset, and adaptive feeding mechanism. When changing the order from a 1.0mm bank card to a 0.3mm game card, the operator first needs to replace the wooden lightweight mold. The die-cutting board does not need to be moved because the positioning pins are always manufactured in the same way. Physical replacement only takes two minutes.
Next, touch the screen to display the saved “0.3mm matte PVC” process formula. This formula remembers the stamping pressure, feed step size, visual positioning mark, and card receiving mode corresponding to this thickness. This machine feeds cards step by step in a very precise way. After changing the thickness, the system will automatically adjust the gap between the clamping forces of the feed rollers. This will prevent thin cards from slipping and thick cards from getting stuck. The entire switching process from confirming the first article to the end should not exceed 15 minutes. This “short, flat, fast” switching solution enables printing companies to undertake various customized card orders, including small batches and cards with unusual shapes. This is because the machine can achieve “sample level precision and batch production level efficiency”, which means that PVC card punching machines can be used for many different things.
Conclusion:
Thanks to the deep integration of 7.5KW servo power, visual correction positioning, and step-by-step feed technology, modern PVC card punching machines can now process cards with thicknesses ranging from 0.2mm to 1.5mm. To ensure smooth edges, please adjust the segmented pressure and stroke of the thick card. Change the clamping and collection path of the thin card so that it does not bend. More importantly, this device is highly suitable for producing small batches of different types of cards in the Indian and global markets, such as gaming cards, anime cards, and bank cards. It has a mold that can be quickly replaced within 2-3 minutes, as well as a solution to quickly switch orders within 15 minutes. After testing, this highly flexible PVC card punching machine can reduce the time required for adjusting multi thickness mixing production by more than 80% and increase the output to over 99.5%. It provides printing companies with everything they need, from sampling a piece of paper to making a large number of copies and then packaging them together.
