Slitter Rewinders
What is the purpose of slitter rewinders?
What is the purpose of slitter rewinders?
Slitter rewinders are designed to slit wide rolls of materials such as paper, film, tape, and aluminum foil into narrower rolls of specific widths, lengths, or diameters and rewind them for further use. These machines are widely used in the material converting industry to enhance production efficiency and product quality.
What functions can slitter rewinders perform?
What functions can slitter rewinders perform?
Using digital control, slitter rewinders can precisely slit materials like films and paper rolls into smaller rolls according to width and length specifications.
What factors should be considered when choosing a slitter rewinder?
What factors should be considered when choosing a slitter rewinder?
The choice largely depends on the type of material to be processed. Different slitter rewinders cater to various materials based on tension requirements. Additionally, factors like working speed, energy consumption, and noise levels should be considered. High-efficiency slitter rewinders can significantly boost productivity.
Shrink Sleeve Seaming Machine
What is the purpose of a shrink sleeve seaming machine?
What is the purpose of a shrink sleeve seaming machine?
Shrink sleeve seaming machines convert film materials into roll stock packaging by performing operations such as unwinding, gluing, traction, and rewinding to produce packaging materials that meet required standards.
Where are shrink sleeve seaming machines used?
Where are shrink sleeve seaming machines used?
The main function of these machines is to produce shrink sleeve labels, widely used in the packaging of beverages, food, batteries, and more. Zontai’s shrink sleeve seaming machines offer automatic size adjustments without molds, meeting diverse production needs at low costs.
What precautions should be taken when using a shrink sleeve seaming machine?
What precautions should be taken when using a shrink sleeve seaming machine?
After setting the appropriate size, select a suitable glue ratio for the material and adjust tension based on thickness. Avoid direct contact with moving parts during operation, and reduce speed gradually when shutting down the machine.
Rewinding Machines
Why are rewinding machines necessary?
Why are rewinding machines necessary?
Rewinding machines are essential for inspecting and correcting issues caused by human errors or equipment malfunctions during production. Many problems can be identified visually or with basic measurements. Rewinding machines provide an efficient solution for inspection and reprocessing.
What precautions should be taken when using a rewinding machine?
What precautions should be taken when using a rewinding machine?
Once the product is securely positioned, start the machine. Operators should remain focused to ensure the rewinding and inspection processes function effectively.
Solventless Laminator
What is the purpose of a solventless laminator?
What is the purpose of a solventless laminator?
Solventless laminators bond layers of film and other materials using solvent-free adhesives. They are ideal for soft packaging manufacturers producing items like zipper bags.
What are the advantages of a solventless laminator?
What are the advantages of a solventless laminator?
These laminators use solventless adhesives that leave no solvent residue, work at high speeds, save energy, and eliminate the risk of aromatic amine migration. This makes them a highly desirable choice for lamination.
What are the adhesive requirements for solventless laminators?
What are the adhesive requirements for solventless laminators?
Solventless laminators require adhesives with excellent bonding capabilities. For Zontai’s products, adhesives that react quickly upon heating are recommended to maximize efficiency.
