Next, let me explain the types of sealing machines and issues to consider when purchasing one.

　　Now, let me explain it to everyone. Plastic sealing machine Types and purchasing considerations

　　To protect our precious photos and documents, we often use plastic sleeves to safeguard them. In the past, we’d take our photos to a photo shop to have them laminated, but nowadays it’s quite common to keep plastic sleeves at home. Below, we’ll share some useful information about laminating machines.

　　Simply put, based on their adjustment methods, they can be categorized into temperature-controlled types and speed-adjustable types. So, let’s take a look at what the differences are.

　　Temperature-controlled laminator: This type... Plastic sealing machine Its key feature is that the pressure and speed are fixed, while the temperature is adjustable. The pressure between the rollers and the rotational speed of the rollers are both set at the factory. The mold temperature, however, can be adjusted by the user himself. The color fastness of the seal is controlled by the plastic sealing temperature. Since the structure of plastic sealing machines varies from manufacturer to manufacturer, the temperature indicated on the machine may not necessarily match the actual plastic sealing temperature. Generally speaking, for plastic sealing machines with pre-heated rubber rollers, the displayed temperature is fairly close to the actual sealing temperature. When operating this type of machine, it’s important to follow the sequence specified in the process requirements step by step. Under constant pressure and speed, if the temperature is too high yet too low, the sealing will be insufficient; if the temperature is too high, deformation and glue overflow may occur. Even if the pressure between the rollers is excessively high, rubber leakage is likely to happen. If repeated temperature adjustments still fail to meet the molding requirements, then the machine’s pressure has a certain adjustable range. You can refer to the product manual, remove the start-up cover, and make appropriate fine adjustments to achieve optimal molding conditions.

　　Speed-adjustable laminating machine: This type of laminator is characterized by fixed pressure and temperature, with adjustable speed. The pressure between the rollers and the molding temperature have already been set at the factory. Users can adjust the molding speed according to their needs. Additionally, there are speed-adjustable laminators with two-level temperature settings. The sealing strength of the certificate is controlled by the plastic sealing speed. In fact, adjusting the speed essentially means changing the molding temperature: a faster speed results in shorter heating time and lower mold temperature; conversely, a slower speed leads to longer heating time and higher mold temperature. Operation of this model should also follow the sequence specified in the process instructions step by step. If the speed is too fast, the document may not receive sufficient heat during the lamination process, leading to poor adhesion. On the other hand, if the speed is too slow, excessive heat will be supplied, causing the sealed document to deform or leak. The pressure of the speed-adjustable laminator also has a certain adjustable range; therefore, please make appropriate fine adjustments as needed, referring to the instruction manual.

　　I’ll teach you how to buy a household laminator.

　　I. Mold Width

　　 Plastic sealing machine The entry width can be set to A4 size, but nowadays household laminators typically come in a more common width. This makes them particularly useful when you need to laminate documents. Of course, they can also handle other common sizes, such as 6-inch and 7-inch photos, A5-sized flyers, and 2R cards.

　　II. Downshifting Function

　　When a machine is in use, abnormalities are inevitable. A common issue with laminators is that when there’s too much rubber, the photos become uneven, or there’s excessive empty rubber, leading to paper jams. In such cases, the laminator’s gear-shift button becomes crucial: when a jam occurs, simply press the gear-shift button and pull out the photo.

　　3. Mold Thickness

　　Molding thickness refers to the total thickness of the molded film that a molding machine can fully mold onto the object being molded. Simply put, the larger the thickness parameter of a plastic material, the wider its range of applications. We can plasticize various types of cards, and we can also increase the thickness of cover papers.

　　The above is for home use. Plastic sealing machine Here are some key points for reference. If you’d like to learn more about laminators, stay tuned to Xiao Bangbo. In the next post, we’ll provide a detailed overview of exactly what aspects you need to consider when choosing a laminator.
