Ruiyi is a professional plastic injection molding company in China, offering custom injection molding, mold design, and plastic injection molding services to manufacturers. Today, we’ll introduce the many benefits of plastic injection molding and processing.
Plastic injection molding is an efficient method to produce plastic parts. By injecting heated plastic into custom molds, manufacturers can precisely control the size and shape of the final product.
Advantages of Plastic Injection Molding
High Flexibility
Plastic injection molding is highly flexible, enabling the production of plastic parts in nearly any shape or size. It serves various industries, including manufacturing parts and medical devices.
This method also allows for easy color changes and material substitutions. Adding fillers to liquid plastic reduces density, boosting part strength and durability.
Cost Reduction
Plastic injection molding is a fast production method that lowers manufacturing costs. The production time per part depends on the mold’s complexity, but standard parts usually take only 15 to 30 seconds.
Using custom molds cuts human error, lowering costs and simplifying operations.
High Precision with Minimal Errors
Injection molds are highly accurate, ensuring a consistent process with minimal errors. Accuracy can reach within 0.005 inches. This precision comes from high-quality molds, ensuring 100% accuracy in each part.
High Material Utilization
Plastic injection molding generates almost no waste. Molds use the exact amount of material needed, and leftover plastic can be ground up and reused in the next production cycle, maximizing resource use.
Long-Term Cost-Effectiveness
Although initial tooling costs for injection molding can be high, the production cost drops significantly once the molds are ready. Over time, this method is more cost-effective than other plastic processing techniques.
Design Constraints
Although plastic injection molding is versatile, it has limitations. It works best for smaller parts that fit in specially designed molds. Additionally, material types and designs may impact the final product’s wall thickness.
