Plastic injection molding is an extremely versatile method of producing plastic parts and has multiple advantages over other methods of plastic molding. Not only is the process simpler and more reliable than others methods, but it is also extremely efficient.
What is Plastic Injection Molding?
Injection Molding is a manufacturing process for producing parts in large volumes. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.
Plastic injection molding uses granular or pelleted plastic resins to produce products ranging from automotive and electrical equipment components to electronic tools, soft material parts, and medical products. One of the most employed manufacturing processes because of its ability to produce enormous amounts of the same item, plastic injection molding uses a variety of plastic compounds such as ABS, POM, organic glass, PP, PC, bakelite, etc.
1. High Efficiency- Fast Production
There are several good reasons that plastic injection molding is known as the most common and most efficient form of molding. The process itself is extremely fast compared to other methods, and the high production output rate makes it even more efficient and cost-effective. Speed depends on the complexity and size of the mold but only about 15-120 seconds pass between each cycle time.
2. Detailed Features and Complex Geometry
The injection molds are subjected to extremely high pressure. As a result, the plastic within the molds is pressed harder against the mold compared to any other molding process. Due to this excessively high pressure, it is possible to add a large number of details to the design of the part.
Furthermore, due to high pressure during the molding process, complex and intricate shapes can easily be designed and manufactured which otherwise would have been too complicated and expensive to manufacture.
3. Cost-Effective
Easy to manufacture with today’s engineered resins, plastic is cost-saving to a lot of companies, with its lightweight durability and easy to mold, plastic is cost savings over many other materials. Another factor that helps reduce cost is automation. A majority of the injection molding process is performed by machines and robotics which a sole operator can control and manage. Automation helps to reduce manufacturing costs, as the overheads are significantly reduced.
4. Minimal Waste Using Injection Molded Parts
If you are on the prowl for a sustainable means of product or part production, look no further than plastic injection molding. Modern-day plastic injection molding is as environmentally friendly as it gets. This process uses only as much plastic as needed to generate the product/part. Though the production process results in some scrap plastic, this material is ground up and subsequently re-used. In the end, injection molded parts are created with little waste, making it quite the “green” product/parts production technique.
5. Multiple Finishes
Most injection-molded parts are produced with a smooth surface finish very close to the desired final look. However, a smooth appearance isn’t appropriate for every application. Depending on the physical and chemical properties of the plastics used, injection molding allows for surface finishes that don’t require secondary operations — from matte finishes and unique textures to engraving and more.
6. Accurate
The plastic injection molding process is effective, consistent and virtually error-proof. It is such a precise method that it can fabricate nearly any type of plastic part. There are certain design restrictions, but the molds that are made allow the finished product to be very precise. Accuracy is typically within 0.005 inches.
7. Color Control
From clear to any color an OEM needs, injection molders can make it happen by aligning plastics, additives, and biocompatibility to achieve the desired coloration. Often, multiple colors are needed in one product. In that case, overmolding is the solution provided the injection molder has the requisite experience in multi-material injection molding.
8. Flexibility
Injection molding is all about flexibility, whether ascribed to some plastics’ properties or the ability for OEMs to make custom color choices or meet specific project requirements. Injection molding gives OEMs freedom in design choices, — especially when compared to metal.
Injection molding is marvelous technology. It allows engineers to design and create many products (or parts of products) in large quantities and thus low prices to the consumer.
