How To Cut Injection Molding Costs Without Sacrificing Quality?
If you're in the market for new injection molding parts, it's time to start thinking about how to cut your costs without compromising quality. There are a few ways you can do this, including on-demand injection molding, larger production runs, and 3D printing. On-demand injection molding A good way to cut the costs of injection molding is to automate the production process. This can eliminate labor costs and reduce variable operational costs. The human workforce is important and flexible, but it also adds to the cost of the finished product. Automation can take care of many tasks, including part removal and sorting, and it can also detect quality variations through visual management. While trained personnel should handle critical decisions, automation should handle routine, repetitive work. Injection molding is a complex process, which involves the molding of liquid or malleable raw material into a specific shape. Each step in the process is influenced by the physical properties of the material being molded. Usually, a mold is made of metal, with one or more cavities. Once the liquid is poured into the mold, it must cool and harden inside the mold to achieve the final configuration. This process may take only seconds for a small part, but for larger parts, it may take minutes. The overall molding cycle time of injection molding can be decreased by adjusting the resin composition, or by reducing the number of steps. Injection molding costs increase with the number of parts being produced. Each part requires a unique mold size. As a result, manufacturers try to keep the mold cycle times low, as this means they can produce more parts in a given time. This reduces the cost of the mold but can mean additional repairs and unnecessary downtime. While it's impossible to eliminate all the factors that cause the cost of injection molding, it is possible to cut costs without compromising quality. Injection molding costs can be controlled through a good quality system and strategic plan. The daily operations of the molding process can be optimized by using mold design best practices. A good design will help you minimize investment costs, and proper machining will lower the per-part cost.
How backpressure affects injection molding?
Injection molding requires good control of back pressure. This helps reduce the amount of shrinkage of the product’s surface and improves product quality. To ensure quality, work with a plastic injection molding company. This ensures you get the highest quality product possible. Back pressure is not an option on every machine. When using high back pressure, it is essential to check the length of the fibers. This is important because long fibers are more likely to break. When choosing plastics for injection molding, always keep in mind the manufacturer’s recommendation and the maximum pressure the plastic can withstand. Back pressure in injection molding can be adjusted according to the product’s structure, size, and color. It is generally set between three and fifteen kilograms per cubic centimeter. When using high back pressure, be aware that it will cause excessive holding pressure on the injection molding machine. It can also result in defects along the parting line or boundary. Unlike high-pressure molding, back pressure does not raise the melt temperature, but it will increase the speed of the injection screw. The screw is responsible for 70-90% of the energy needed to melt plastic, so it is essential to adjust back pressure accordingly. It can reduce glue walking around the product. Back pressure in injection molding is a factor that can help minimize glue walking around the product. This pressure is usually set at three to 15 kilograms per cubic centimeter. The exact back pressure needed for a specific product depends on its structural design, the quality of the raw materials, and drying conditions. Back pressure exerted in injection molding can also increase during color mixing, airiness, or shrinkage. It can also be decreased to reduce the effect of salivation or glue leakage. Proper back pressure in injection molding is critical to achieving the best plasticization quality. Without it, the injection unit volume is unstable, and glue walks around the product. Low back pressure can also lead to product weight and size changes. It can also cause the glue to leak out of the nozzle and reduce plasticization efficiency. Moreover, excessive back pressure can lead to the premature burnout of the heating ring near the nozzle, and increase the mechanical wear of the pre-molding mechanism. Proper back pressure in injection molding is also important for the quality of the molten material. It can help eliminate the possibility of glue walking around the product. Proper back pressure reduces the amount of glue walking around the product and keeps the screw in the bottom of the products. Proper back pressure also helps in the removal of old colorants during color change.
