    Injection Molding Plastics Since the introduction of the injection molding process for the first time in the 1930s, the advantages of injection molding over die casting have been controversial. This approach has both benefits and limitations, mainly based on requirements. pet preform manufacturers and other consumers who rely on molded parts to produce products are looking for factors such as quality, durability and economy to determine which molded parts are best suited to their needs.What is injection molding?Injection molding is a method of manufacturing a finished part or product by pressing a molten plastic into a mold and hardening it. The use of these components is as extensive as the various products produced by the process. Depending on the application, injection molded parts can range in weight from a few ounces to hundreds or thousands of pounds. In other words, from computer parts, soda bottles and toys to trucks, tractors and car parts.Injection drawingPlastic injection molding and die castingThe injection molding process was originally modeled by die casting, a similar process in which molten metal is pressed into a mold to produce parts for making the product. However, die casting mainly uses non-ferrous metals such as zinc, aluminum, magnesium and brass instead of using plastic resins to produce parts. Although almost any part can be cast from any metal, aluminum has developed into one of the most popular metals. It has a low melting point which makes it easy to form parts. The mold is stronger than the mold used in the permanent mold process and can withstand high pressure injections of 30,000 psi or higher. The high pressure process produces a durable, fine grade structure with fatigue strength. Because of this, die casting is used from engine and engine parts to pots and pans.Die casting benefitIf your company needs rugged, durable, mass-produced metal parts such as junction boxes, pistons, cylinder heads and engine blocks, or propellers, gears, bushings, pumps and valves, die casting is the ideal choice.StronglastingEasy to mass produceDie casting limitHowever, it can be said that although die casting has its advantages, there are some limitations in this method that need to be considered.Limited part sizes (up to approximately 24 inches and 75 pounds.)High initial processing costMetal prices will fluctuate significantlyWaste increases production costsInjection molding benefitsFor many years, the benefits of preform injection molding of Pet Bottle Preform have become more popular because of their advantages over traditional die-casting methods. That is to say, the number and variety of low-cost, inexpensive products made today from plastic are almost limitless. There are also minimum finishing requirements.
