Integrate exceptional quality and performance into your products with insert molding services that provide consistent strength and reliability. At Rapid Precision, we assist with the integration of plastic and metal parts to become one unit, which decreases assembly time and improves prototype and full production structure integrity.





Insert molding is a production technique in which ready-formed metal or plastic inserts are embedded into a mold and then molten resin is forcefully injected into the mold around the inserts. The molding method produces a single, integrated unit that is highly mechanically stable, aligns uniformly, and performs consistently over time. Insert molding is also highly beneficial in eliminating secondary assembly, improving electrical flow, load durability, and overall reliability of the product.
It provides insert molding with great attention to detail and seamless production. Our engineering team evaluates each component which is placed into the metal cavity with respect to the bond strength and the mold design to ensure quality in every cycle of production. We provide services for rapid prototyping, low to medium volume runs, and high-volume production for steel and aluminum tools. We offer design-for-manufacturability feedback, mold flow analysis, and other ISO-certified quality control. We will manufacture your products with the tolerances, insert retention, and finishes you need. We assist you in speeding up the process from validation to mass production with no quality loss.
