In today's packaging field, foam as a new type of environmentally friendly packaging material, is increasingly demonstrating its indispensable position. It has many advantages such as light weight, environmental protection, and excellent chemical properties. It can meet the special needs of various types of packaging. Its surface is smooth and flat and soft to the touch. From high-end electronic products to daily fresh fruits and vegetables, foam packaging can be seen everywhere and has become the "darling" of packaging materials. However, to process rolls or large pieces of foam into various shapes and sizes, and accurately and efficiently meet the packaging needs of different products, professional cutting equipment is indispensable, and the oscillating knife cutting machine is one of the best.
EVA foam

It is formed by foaming to produce countless independent bubbles and has many advantages such as light weight, environmental protection, and excellent chemical properties. and it is environmentally friendly and recyclable.
Sponge
As a porous foam material, it is soft and ductile. It has good cushioning properties. It has good water absorption properties to prevent liquid products from leaking.
 | Vertical foam cutting machineVertical cutting machines are relatively efficient. It is capable of simultaneously cutting through several layers of foam. the height of the cutting may even reach 50cm. The drawback of the vertical cutting machine is that it is suitable for straight cuts but doesn't support complex shapes. And it cannot cut the positioning groove inside the package. |
 | Laser foam cutting MachineThe laser cutting machine melts the material to cut. the high-energy laser beam focuses on the surface foam, thus able to cut fine and complex patterns. However, it will produce a very horrible odor and gas during cutting. It doesn't meet the environmental protective requirement. And it cannot cut thicker and harder foams. |
 | Hydraulic die foam cutting machineThe die cutting machine is capable of doing much cutting in a short time. With the aid of the mold design, an entire series of foam products can be punched in bulk. It is suitable for high-volume productions, thus really enhancing production volume. However, this is very costly in terms of designing and producing the mold and not suitable for small-scale customized production. |
Before the oscillating knife cutting machine was widely used, the foam processing field faced many difficult problems.
Manual cutting is extremely inefficient and cannot meet the timeliness of batch orders. The precision error of manual cutting is often several millimeters or even larger, which affects the protective performance of the packaging.
The die cutting machine has certain speed advantages in mass production, but the mold cost is high. A set of complex molds can easily cost thousands of yuan or even higher. The mold production cycle is long, usually taking several days to several weeks. This is extremely inflexible for small batches and diversified orders.
The laser cutting machine has high precision and can cut complex and fine patterns, it is easy to produce pungent odors and harmful smoke when cutting foam. And there is a risk of fire.
The Hot wire cutting machine is prone to adhesion and drawing foam. The cutting surface is not smooth, with wavy lines and adhesion. The cutting surface will harden due to heating and melting.

As the basic load bearing component, the foam sheet cutting machine body is welded with high-strength stainless steel. Fine processing ensures that the installation surface is extremely accurate and provides stable support for the foam board. Prevents the cutting process from causing accuracy deviation due to shaking and depression of the bed.
The adsorb system uses a vacuum pump to generate a strong negative pressure and tightly adsorbs the foam through the dense holes on the table. Ensure that the foam will not move under high-speed vibration cutting. Ensure accurate cutting accuracy. You can also add a partition control function, which can intelligently adjust the adsorption force distribution according to the size and shape of the foam to further optimize the fixing effect.
The cutting tool is the core of the foam board cutting machine. There is a wide variety of vibratory knife tool, V-cut tool, and circular knife tools concerning the cutting process. The blade is made of high-hardness, high-wear tungsten steel. The firm blade on the cutting tool vibrates tens of thousands of times a minute to cut this foam more accurately and effectively.
Immersed as the brain of equipment, the control system integrates CNC technology, motion control, and intelligent man-machine interactive interface. On one side, it operates to the commands like cutting graphic dimensions and process parameters given by the operator. It converts their data into accurate signals to drive motors, vacuum pumps, and their other constituent subassemblies to work in synchronization. Secondly, it monitors in real-time the operating condition of the equipment and feeds back positional, speed, and temperature data amongst other things. In case of faults, the equipment is to sideline warn and turn itself off to provide protection.
Power is supplied to machine movement through the motor. The source of this power consists of servo motors and drivers that provide fast running speed and high accuracy to the cutting machine using a dipping vibration knife. Movements are converted from motor actions into actions of each component as transmission moves such as movements forward, backward, side to side, lifting knife heads, or rotation.
The CNC foam cutter machine is a major innovative achievement in the field of the modern cutting industry. It mainly relies on high-frequency vibration technology. When the equipment is turned on, the cutting head, under the precise command of the control system, reciprocates up and down at an ultra-high frequency of tens of thousands of times per minute to cut the foam. At the same time, with the help of a powerful adsorption device, the foam sheet is firmly fixed on the cutting platform to ensure the stability and precision of the cutting process.
In the process of foam packaging cutting, cutting accuracy is directly related to product quality and market competitiveness. With advanced CNC systems and high-precision transmission components, the foam cutter machine can easily cope with such stringent requirements. It can achieve millimeter-level or even higher precision cutting. Makes smooth and neat edges, no burrs, sawtooth and other defects, ensures that the foam products fit the product perfectly.
On the one hand, the production efficiency of the foam board cutting machine shortens the labor cost of a single product. On the other hand, the vibration knife cutting machine does not need to replace expensive die-cutting molds, nor does it need to reserve a large amount of mold inventory. This reduces the cost of mold purchase, maintenance, and management.
When the foam sheet cutting machine cuts foam, there is no smoke, no odor, and no dust throughout the process. Ensure the cleanliness of the workshop environment and the health of workers. In terms of energy consumption, the vibration knife cutting machine adopts advanced energy-saving motors and intelligent control systems, with low operating power consumption and an hourly power consumption of about 5 kWh.
Product packaging needs are becoming more and more diverse and personalized. With powerful software compatibility and convenient programming functions, The foam CNC cutting machine can easily cope with various complex and changing orders. Just modify the cutting parameters and import new graphics on the computer, and the machine can quickly switch tasks without lengthy debugging.
The intelligent layout software of the foam digital cutting machine is the key to saving materials. It can simulate layout through sophisticated algorithms based on the size of foam coils or plates and the graphics to be cut. Strive to make the most of every inch of material. Reduce waste costs and reduce production costs.
The easy-to-operate characteristics of the digital knife cutting machine greatly liberate manpower. After a short period of training, ordinary workers only need to operate the software and monitor the operation of the equipment in front of the computer to complete complex cutting tasks. Everyone can control the work of multiple machines, optimize human resource allocation, and enhance comprehensive competitiveness.
In today's diversified market environment, choosing a foam cutting machine that suits its own needs is crucial for enterprises to improve production efficiency, ensure product quality, and control costs.
The reason why the sponge cutting machine can show its prowess in the field of foam cutting is due to the diverse and suitable knives.
Electric vibration knife
The electric vibration knife is driven by a motor to vibrate the blade, with large torque. It is more suitable for cutting foams with higher hardness, such as EVA foam. It can also cut EPE foam, but the cutting speed is slower. It cannot cut foams that are too soft, such as sponges.
Pneumatic vibration knife
The pneumatic vibration knife drives the blade to vibrate with high pressure gas. The vibration amplitude is large. It is suitable for cutting materials such as foam and sponges with larger thickness and lower hardness. In addition, it must be used with an air compressor.
Milling tool
The milling tool is a high speed rotating drill bit. It is used to carve an impermeable inner groove on the foam. Matching the vibration knife cutting process can achieve one-piece molding of the packaging lining. Reduce subsequent composite pasting and other processing processes.
You need to accurately grasp the type, thickness, and density range of foam in daily production. To choose the correct processing width and blade configuration combination. The processing width and processing height can be customized according to customer requirements.

Before starting the EPE foam cutting machine for cutting operations, comprehensive and detailed debugging work is essential, which is directly related to the accuracy and efficiency of subsequent cutting.
First, check the cutting tool to see if the blade is sharp and worn to ensure that the blade is in the best condition.
The reasonable choice of cutting speed requires comprehensive consideration of the thickness and density of the foam. Generally speaking, the greater the thickness and the higher the density, the cutting speed should be appropriately reduced to prevent the tool from overloading and breaking, and the cutting surface from being rough.
The knife depth needs to be adjusted just right. Too much knife depth will damage the felt on the cutting table, and too little will not cut through. It is necessary to test based on the foam to find the best knife depth.
Be sure to fix the foam board properly before cutting. otherwise, the foam board will be displaced and deformed in the cutting process. This will seriously affect the cutting accuracy and even damage the tool. The vacuum adsorption platform uses a strong negative pressure to tightly adsorb the foam to the table to ensure that the cutting is stable and motionless throughout the process.
The cutting can be started by importing the graphics into the EVA foam cutting machine. During the cutting process, the operator needs to monitor the working status of the machine. Once abnormal noise or material movement occurs, the machine should be stopped immediately and the problem should be checked.
Daily cleaning is the basis for ensuring the stable operation of the PE foam cutting machine. After each use, be sure to clean the cutting platform in time. Use a soft brush or vacuum cleaner to remove the residual foam debris, and prevent the debris from accumulating into the transmission parts of the equipment, affecting the accuracy and smoothness of operation.
Careful maintenance of mechanical parts is essential to extend the life of the equipment. Add special lubricating oil to the moving parts such as the transmission guide rail and rack every week, and follow the lubricating oil model and filling cycle recommended in the equipment manual to ensure smooth operation of the mechanical structure and reduce friction and wear. Check each connector and fixing bolt for looseness every month. If found, tighten it in time to prevent cutting deviation caused by component displacement.
Regularly check whether the wires and cables are damaged or aging. If the insulation layer is damaged, replace it in time to avoid the risk of leakage short circuit. Clean the internal dust regularly to prevent dust accumulation from causing poor heat dissipation of electrical components or causing failures. At the same time, regularly check the grounding of the equipment to ensure reliable grounding.
The consumables of the EPE foam cutting machine are blades and felt. The service life of the blade is generally 10 days, depending on the hardness of the material and the working time. The service life of the felt is generally two years. It is necessary to regularly check and replace wearing parts to ensure that the machine is in good working condition.
The foam cutting machine runs at high speed, and its safety guarantee is crucial. This is related to the safety of the operator and the stability of enterprise production.
| Safety deviceThe safety light curtain is an outer safety barrier. Once an object or person breaks into the cutting area, the light is cut off instantly, and the equipment is emergency braked to effectively prevent the operator from being injured. Emergency stop switches are installed on the four corners of the machine and the operating table. When the machine fails or has abnormalities, the operator can stop the machine in time to avoid and reduce injuries.
|
| Safe operationAt the level of operating specifications, enterprises should strengthen training and supervision. New employees need to receive system safety training when they join the company. Be familiar with the location and function of buttons such as equipment start, pause, and emergency stop. Illegal operations are strictly prohibited, such as fatigue operation and operation after drinking. During the cutting process, it is strictly forbidden to cross the boundary of any part of the body into the cutting area. Cleaning waste and adjusting materials also require stopping the machine. During maintenance, power-off and sign-out are key steps. Maintenance personnel should sign out to warn others to prevent others from starting the equipment by mistake. |
First, clean the machine and apply an anti-rust treatment such as oiling the transmission parts. The accessories and knives are properly packaged and placed in the toolbox.
Provide comprehensive protection for the equipment and cover the machine with plastic bags to cope with the hot and humid environment of sea transportation. Wrap the machine tightly with soft materials such as bubble film to prevent collision damage. Finally, pack the whole into a fumigation-free wooden box.
Due to the large size of the equipment, most of them are transported by sea. If the machine is urgently needed, it can also be transported by air. Subsequent purchases of accessories are mostly transported by air.
Before the newly purchased foam CNC foam cutter machine is put into use, correct installation and professional training are essential. It is directly related to whether the equipment can operate normally, and perform at its best performance and the safety of the operator.
Site selection: First, select a suitable site according to the equipment manual. The site should be flat and dry. The space must meet the requirements of equipment deployment and surrounding operation and maintenance, and the ground-bearing capacity must be adapted to the weight of the equipment.
Unpacking: Carefully remove the packaging and check the parts one by one against the packing list to ensure that there are no omissions or damage.
Leveling: After placing the machine on the ground, use a level to measure and calibrate in multiple directions.

Install cutting tools: Accurately install the cutting tool and blade according to the operating instructions, pay attention to blade protection, and prevent collision damage.
Power connection: Professional electricians operate according to the electrical diagram, distinguish between power and control lines, ensure reliable grounding, and prevent leakage accidents.
Theoretical training covers the explanation of the structure principle of the equipment. so that operators can understand the coordinated operation mechanism of the cutting machine, adsorption, cutting tools, and control system.
Introduction to the cutting process, teach the best parameter settings based on the foam material and thickness, such as the difference in cutting parameters between foam and EVA foam.
Safety knowledge is emphasized, including the principle of equipment protection devices, operation restricted areas, emergency response, such as safety light curtain trigger mechanism, and accidental touch risk prevention.
Practical training is conducted next to the equipment, guided by experienced masters. New employees start with simple graphic cutting, familiarize themselves with software drawing, importing, and typesetting processes, master equipment startup, pause, and speed regulation operations, and gradually advance to complex graphics and batch order cutting. They learn cutting process monitoring and preliminary troubleshooting, such as tool jamming and material displacement processing. After passing the theoretical and practical assessments, they can independently take up their posts and lay a solid foundation for human and technical foundations for foam cutting production.
With the rapid development of science and technology and the continuous upgrading of the manufacturing industry, vibration knife cutting foam technology will also embark on a new journey.
The degree of intelligence will be further deepened. With the help of artificial intelligence and Internet of Things technology, the vibration knife cutting machine will realize functions such as self-diagnosis, fault warning, and remote control. Operators can control the operating status of the equipment anytime and anywhere through mobile phones or computer terminals, arrange maintenance plans in advance, and greatly improve production stability and management efficiency. In addition, the automatic loading and unloading functions are more complete, eventually forming an unmanned automated production line.
