The guide pin also prevents displacement of inserts when they are used. For optimal performance, the guide pin should be positioned 15 to 25 mm above the product. Additionally, the slider guide pin, located 10 to 15 mm below the mold guide pin, directs the movement of the slide, ensuring it operates correctly.

In this case, a slider mechanism is needed. Before injection molding, pull the slider horizontally to ensure smooth demolding. So, the slider is a component within the mold structure that can move along the axis of the mold. It is usually used to adjust the opening height of the mold and assist in demolding and other functions.

Hydraulic slides are employed when cam pins might exert excessive pressure on the gibs, which control the slide’s linear motion. These slides use hydraulic cylinders to move the slide, offering several benefits:

Seaway Plastics has four decades of experience and a proven track record engineering, manufacturing and assembling high-purity medical devices that are designed for disposable, single-use applications.

Safety measures, such as implementing limit switches for ejection under slide details and ensuring proper locking mechanisms, are essential to prevent accidents and ensure operator safety. Regular training and adherence to safety protocols are also crucial for safe operation.

An injection mold slider is a component used in injection molds to create features like undercuts, holes, or grooves in molded parts. Its role is to facilitate the ejection of the molded part from the mold cavity by moving laterally to release the part from the mold.

By partnering with Seaway Plastics to streamline all steps in the complex manufacturing process, OEMs are able to be more competitive, safeguard their own brand reputation and focus on meeting the needs of their end customers — healthcare professionals treating patients in hospitals, physician practices and other clinical settings. Ultimately, this team effort is critical to support the shared end objective — which is to support and enable optimal health outcomes for patients.

There are many important advantages to selecting a manufacturing partner that is able to take ownership of every step in the process in-house — from engineering services to prototyping to fully validated production — without the need to involve additional partners or create multiple outsourcing arrangements. Specifically, for OEMs, the demonstrable advantages such a tightly integrated approach include:

In injection molding, it is common to encounter parts with various intricate features such as grooves, holes, or undercut structures. Normally, during the injection molding process, once the parts are molded, the core and cavity must separate, and ejector pins are used to remove the part from the mold. However, when parts have undercuts, holes, or grooves, they prevent the core and cavity from separating normally.

The ability to produce precise surgical robotic tools and assemblies that meet all of the rigorous engineering and regulatory specifications is another way in which both Seaway Plastics and its OEM customers are supporting surgeons and other medical practitioners in their quest to guarantee accuracy and repeatability during surgical procedures — thereby enhancing patient safety and overall health outcomes.
