What is Large Component Injection Molding?
Large component injection molding, also known as high-tonnage injection molding, is the production of large plastic components using injection molding technology. When molding large components, more than just a larger press is needed; the complexity of the item doubles or even quadruples, and the smallest details become more important. Proper mold design is essential, as even the smallest mistakes can exacerbate possible problems such as uneven textures, weld lines, gate white spots, or flow and weld lines. One of the most significant differences between small and large component molding is the cost-quality, which is significantly higher in the latter. The initial lead time for this method will also be a bit longer than small component injection molding, as this type requires a larger steel block that takes longer to mold.
During large component injection molding, plastic resin is forced into the mold cavity using extremely high pressure. Since the mold is composed of two different parts, a certain amount of force must be applied to hold the two halves of the mold together. This force is called the clamping force, and it can be used to easily calculate the required tonnage – a number that grows in direct proportion to the size of the part being produced. Large plastic injection molding technology is used in a variety of industries to produce a range of products from automotive parts to projectors.
Why is Large Part Injection Molding a Specialty Service?
Large part injection molding requires specialized machines and tools. That is, they are made with what we call large-tonnage injection molding machines, which consume a lot of resources. They take up more space on the factory floor, and each machine is expensive to operate. The capital cost of just one large-tonnage machine is also much higher than any other injection molding machine. The injection molds used in these machines also require special care. They are very heavy and require special lifting equipment to install and remove as needed. Handling the large plastic parts made by these machines also requires considerable space for preparation, packaging, and storage. These considerations limit the number of companies that can provide large part injection molding services.
Benefits Of Large Part Plastic Injection Molding
Large part injection molding might require the right equipment, skills, and budget, but it has its benefits too. We can help you experience these advantages if you work with us:
High Volume Production
Injection molding of large parts is primarily done to produce large size parts in big batches, which can be done reliably and with shorter cycle times than other plastic manufacturing methods. It’s a necessity when the same part needs to be recreated thousands of times in succession. This is beneficial if you’re in an industry in need of such parts in a specific time period.
Minimal Waste
Compared to other processes, injection molding of large parts creates fewer waste plastic or scraps, so it’s more cost-efficient. Having fewer scraps means that manufacturers don’t have to waste too much plastic resin in the process. The resin used during the manufacturing process can be maximized.
Fast Cycle Time
Many businesses choose large part injection molding, because it is more efficient. The time it takes for the plastic part to be manufactured is short, so more products can be produced in a short amount of time.
Versatility In Design
Large part injection molding is used to create a variety of products — from plastic decking, to large-size electronic casing and enclosures, to plastic chairs and tables, and many large-format items and designs you can think of.
