Product identification plays an extremely important role in communicating a product's position and brand in the marketplace. Plastic nameplates can convey messages, brand, classifications, description, schematics, warnings, instructions and a number of other types of product information.
Plastic injection molded nameplates help to spot your products and help them be noticeable in the crowd. Before we go further, let's take a quick consider the plastic injection molding process.
The Plastic Injection Molding Process
The plastic insert molding process isn't a complicated one. Molding processes of the sort involving metals return back many years, and basic principles have not changed, just the techniques and materials.
Needless to say, you have seen what the finished product looks are. You've seen them more times than maybe you are aware of. You've seen them as car emblems, appliance and industrial nameplates, custom plastic nameplates, recreational product nameplates, point-of-purchase, plaques and signs. They fill the entire world around you, but have you any idea how are they made?
The process begins with a plastic pellet manufactured from a composite of organic and inorganic polymers, plus additives to assist in the melting process. This small pellet is tossed right into a hopper with 1000s of other pellets. This begins the journey from pellet to product. The next phase is preparing the plastic.
The pellets are released onto the threads of a giant rotating screw. Since the pellets travel along, they're heated to melting temperatures, around 400 degrees Fahrenheit. Needless to say, the bigger quality the plastic is the bigger temperature it requires to melt it. The pellets are rolled over the screw because the process also requires friction and force. The screw provides both because the pellets roll along its surface and crash into each other.
Now that all three requirements are met, friction, force and heat, the pellets commence to liquefy and the next step of filling begins. The screw continues to guide the liquid plastic along its threads to a valve. Under high pressure the valve forces the plastic right into a custom designed mold - manufactured from heat resistant metals - until every cavity is filled. Once this is achieved the mold adopts the holding phase. The filling and holding phases are crucial steps in the plastic injection molding process. Their execution will determine the quality of the finished product. The metals we use for the mold insure that the last piece made carries exactly the same qualities because the first.
The Next Step
The pressure on the mold is maintained as the molten plastic cools to a good state. This stage might take a few momemts because the mold absorbs the warmth from the melted plastic, and in turn is cooled by coolant that encircles it. While the part is cooling, the screw returns to its original position, collecting more pellets from the hopper. The merchandise is then ejected from the mold and moves to its secondary processes such as decoration, sub assembly, or shipment. The mold closes, and the process begins around again.
Features of the Plastic Injection Molding
There are several important benefits of utilizing injection-molded plastic:
The plastic injection molding allows complex and intricate shapes to be manufactured. Shapes that could be too difficult or costly to manufacture with various processes.
The plastic injection molding provides for a high level of plastic nameplates and custom plastic signs to be manufactured at once with exactly the same mold and quality.
The metal molds have a lengthy life. When you keep coming back for a future order, the mold will soon be ready and your next order will soon be identical to your first. Furthermore, their initial cost is low too.
The plastic nameplates may be decorated in many different ways such as textures in the mold, metallic foil, ink, UV protection, and more.
