Types of Laminating Machines
I. Coating Type This type of equipment involves three main operations: adhesive application, drying, and hot pressing. The operation requires precision. Its advantage lies in reliable product quality. However, a significant drawback is the emission of harmful gases when using oil-based adhesives. As a result, this technology has been entirely banned in developed countries like Europe and America. Water-based adhesives, although more environmentally friendly than oil-based ones, come at a relatively higher cost.
Applicable Scope: Suitable for laminating color printing, packaging paper, flexible films, and soft boards, imparting a glossy surface, vibrant colors, and waterproof properties.
Detailed Description:
The base and side panels are constructed using cast iron, ensuring no deformation, maintaining precision during use and part replacements.
Precision-made coating and metering rollers with concentricity error controlled within 0.01mm for uniform adhesive application and reduced glue consumption.
Precision mirror treatment on hot composite steel rollers ensures excellent laminating finishing.
Electronic automatic temperature control device.
Uniquely designed hydraulic system for precision and stability.
Optional reel-to-reel paper feeding device for composite materials.
Customizable for water-based or oil-based usage as per user requirements.
II. Pre-Coating Type This machine involves single-step lamination, using consumables pre-coated with adhesive. During lamination, the adhesive is melted by heat and then pressed to bond the film onto the printed material. This type of laminating equipment is cost-effective, easy to operate, and does not produce harmful gases during operation. It's considered a trend in lamination technology and, in today's environmentally conscious society, is believed to eventually replace the coated type. However, this technology is not yet fully mature domestically and has some issues to resolve, such as single-side curling (although machines addressing this exist, they come at a higher price) and difficulty in laminating prints with silicone oil. Widely applicable in short-run printing and digital quick-print industries.
Principle of Laminating Machine Usage
Using coating film as a cover can protect paper, extending the lifespan of covers or printed surfaces, especially beneficial for student textbooks, leading to increased usage.
Imprints are less prone to damage. Coating films enhance color and protect colored prints from wear, facilitating various artistic designs on covers or print surfaces as needed, further driving increased usage.
Coating film production is profitable, with low production costs, ease of implementation, and potential for profit, benefiting companies.
Mechanical Functions of Laminating Machines
Equipped with continuous paper feeding device to ensure uninterrupted production.
Large-diameter pressure rollers increase production speed and ensure smooth and glossy composite products.
Combined powder removal mechanism ensures effective powder removal (powder removal device included).
Advanced drying channel structure ensures rapid drying of adhesive on the film.
Adjustable disk-type rotary cutter for paper cutting.
Motor uses frequency conversion control for safety and reliability.
