Newly Designed "XV Screw" Eliminates Variation in Weighing Time

XV Screw (Expanded Volume Screw) is now available for large-volume molding of LCP resin, which is often used in connector parts. It prevents machine stoppage due to sudden fluctuation of metering time and improves mass production. *Patent pending

Problems in LCP molding

 jp-0047-02.png

LCP is a resin with low viscosity, making it difficult to stabilize the weighing time. Increasing the number of strokes increases the weighing stroke and makes weighing unstable. To ensure stable mass production, the screw diameter must be increased, but this increases equipment costs.

Screw design focused on the slippage of low-viscosity resin

LCP, a low-viscosity resin, is highly fluid, and the solid resin may slip in the cylinder during the melting process, causing voids and inconsistent metering times.
The XV screw focuses on this "slippage" and employs a design that suppresses slippage and ensures stable conveyance.

Case Study

 jp-0047-04.png

The XV screw is effective not only for LCP, but also for low-viscosity resins such as PA. With the development of automatic operation and AI, demand for products that use LCP, such as connectors, is increasing, and demands for increased productivity through increased take-up and reduced downtime are expected to grow stronger.

For stable production, it is important to use not only the screw but also appropriate condition settings and functions, so please contact us if you are considering increasing the number of LCPs or if you are concerned about metering variation.
