As an efficient integrated molding process, in-mold injection molding is widely used in automotive parts, electronic casings, medical devices and other industries. Its core requirement is to accurately and orderly feed inserts into the mold to ensure the fit between inserts and plastic molding, which directly affects the structural strength and appearance accuracy of products. With its simple and practical design, our automatic alignment machine has become an efficient auxiliary equipment in the in-mold injection molding production process, perfectly adapting to the automatic alignment needs of various in-mold inserts, helping enterprises solve the pain points of manual alignment and improve production efficiency and product qualification rate.

In in-mold injection molding production, inserts are mostly small precision parts with large batches and high arrangement requirements. Traditional manual alignment is not only time-consuming and labor-intensive, but also prone to insert misplacement and collision due to manual operation deviations, which in turn causes mold damage and product scrapping, increasing production costs. Our automatic alignment machine does not require visual recognition or robotic arms. It adopts a core design of a vibration plate with a fixture plate in the middle. The insert raw materials to be aligned are placed on the front and rear sides of the vibration plate respectively. After the machine is started, the vibration plate tilts back and forth, and after 3-4 cycles of stable vibration, the scattered inserts can be accurately arranged on the fixture plate with stable alignment accuracy and effective avoidance of insert damage.

Whether it is small inserts such as automotive interior parts and electronic buttons, or the mass production of various special-shaped in-mold inserts, this equipment can be flexibly adapted and put into use quickly without complex debugging. It is easy to operate and has a low failure rate, which can work continuously for 24 hours, greatly reducing labor input and labor costs. At the same time, it ensures the consistency of each batch of insert arrangement, provides standardized materials for the subsequent in-mold injection molding process, effectively improves molding efficiency and product qualification rate, and helps in-mold injection molding enterprises optimize production processes and enhance market competitiveness.
