The rubber-to-metal bonding process involves the rubber, the bonding agents and the substrate. Once the rubber is determined, the bonding agent can be determined, and they generally consist of a polymer-solvent solution, a primer coat based on phenolic-style resins and a top layer of polymers and other materials. To apply the bonding agent, a primer coat must be sprayed over a slightly wider area than the topcoat through the use of a barrel spraying machine. The substrate and the rubber must then be pressed together to enable the bonding to occur. Many types of laminate machines are available nowadays. These machines range from small, inexpensive desktop models for office use to more costly, extensive industrial varieties. Top-of-the-range machines typically accommodate a wide variety of document sizes and temperature settings. They may also include multiple sets of rollers for a perfect finish in applications where quality is key. Lamination typically involves attaching a plastic cover or wrapper to the paperwork. This is normally to protect it from damage and ensure it remains in good condition for longer. The document's plastic coating can also enhance colour and improve presentability. In addition, it provides a wipe-clean surface for use with dry-wipe pens.

There are numerous types of laminators available for handling different sorts of documents, pouches and workloads. In this section, we’ll take a brief look at some of the more common varieties found in many homes and offices today, and which sorts might be best suited to which type of production environment. A3 Laminator Again, the key decisions when looking to buy heavy duty or industrial laminators will generally come down to the degree of flexibility required, and the intensity of use you expect it to undergo. Heavy duty laminating machines can be built to withstand near-constant use, but you can expect to pay a premium for this sort of durability and consistency of performance. Conveyor rollers are most commonly found on production lines or in large warehousing situations. Roller units allow users and machines to move objects both large and small with ease. Using rollers allows the user to work with minimal risk when working with heavier objects or awkward loads as a conveyors roller distributes the weight of an object across multiple rollers allowing for even and safe travel, this ease of use provides a more efficient and safer working environment. How do Conveyor Rollers work? Strictly speaking, lamination technically refers to the process of applying a plastic cover to the surface face of a document or other item. Two-sided lamination, where the plastic cover forms a complete seal all around the document on both the front and reverse sides, is more properly known as ‘encapsulation’. Extruded rubber is a group of products made by softening and pressurizing an elastomeric compound and forcing it to flow through a hard tool called a die. The resulting product is a continuous piece of material that has the same cross-section throughout its length... Rubber MoldingWhen it comes to choosing whether to buy a hot or a cold lamination machine, the key differences between the two (apart from the obvious!) really come down to the types of documents you’ll be working with. Many models intended for more intensive day-to-day school or office use come with handy time-saving features such as built-in memory functions, meaning you don’t have to re-programme the machine each time you want to use it. Industrial/Heavy Use

Pouch Laminators - This is the most commonly used type of desktop-type laminating machine on a day-to-day basis, and it can be found in a wide range of standard office environments. Prior to feeding a document into a clear plastic pouch or wallet lined with adhesive, pouch laminators must be heated to optimal temperatures. The sealed cover is then formed by pressing the two together under hot rollersOnce manufactured, for lamination there must typically be three sets of rollers: a drive roller, a guide roller and a laminating roller. There must be a 1:1:1 ratio of these three roller types. The guide roller and the laminating roller rotate in direct correlation to the rotation of the drive roller. However, most people use ‘laminating’ as a somewhat catch-all term to mean any form of heat-based plastic coating process, including full sealing of documents in purpose-designed double-sided pouches. All laminators will come with their own specific step-by-step instructions, and these should always be your first port of call when looking for guidance on how to use a laminating machine. However, there are rules of thumb which are common to laminators, and it pays to know the general workflow for laminating prior to inserting your first document. Some high-end laminating machines can adjust temperature and feed-through speeds for efficient and effective handling of heavy-duty pouches or larger workpieces. In addition, some may feature sensors to automatically detect and reverse misfeeds. When using a pouch-style laminator to seal plastic wallets or films together around an item, the document and its pouch are usually assembled first outside the machine. In some cases, these are then placed inside an additional protective cardboard cover, known as a carrier.
