Insert Injection Molding

In the world of industrial hardware and robotics, strength and versatility are paramount, which is why our insert injection molding services are in such high demand. This process involves placing a pre-formed component-typically a threaded brass insert, a stainless steel pin, or even a pre-stamped metal frame-into the mold before the plastic is injected. The plastic then solidifies around the insert, creating a single, incredibly strong part that combines the structural properties of metal with the design flexibility of plastic. At our Hangzhou factory, we have perfected the art of "insert injection molding" for robotic dog frames and high-torque motor housings, ensuring that the metal inserts are perfectly centered and will never pull out under stress.

Quality control is the most critical aspect of "insert injection molding". A misplaced insert can destroy a mold or result in a part that fails in the field. To prevent this, we utilize precision-engineered jigs and, for high-volume runs, automated robotic loading systems. Our technical team performs pull-out and torque tests on every batch to verify the bond strength. This dedication to "insert injection molding" has made us a trusted supplier for automotive manufacturers who require durable fuel pump housings and pipe fittings. We don't just provide parts; we provide peace of mind. Our ISO 9001:2015 certified processes ensure that every threaded insert is clean, upright, and ready for your assembly line, saving you the headache of secondary tapping or drilling operations.
