Technology Showcase, Hot Runners and Mold Components

These hot runner system nozzles from Thermoplay are made especially for molding large parts, as they screw into the manifolds at various inclinations, guaranteeing ideal perpendicularity for ejection. Sequential injection controls the material flow at joining lines, and because the system includes a network of joints that distributes the expansions inside the manifold, it enables the use of shorter-length nozzles.

SISE offers several lines of hot runner temperature controllers, including the World Series modular range, which controls five to 12 zones. Specially designed for the North American and Asian markets, this temperature controller is a microprocessor-based, single-zone unit compatible with virtually all standard mainframes.

The Multitech line from INglass’ HRS Flow brand offers hot runners designed for fast cycle times and high production volumes, making them well-suited for injection molding of packaging, caps and closures, and products for the medical, electronics and automotive industries.

The Emerald hot runner system from PCS Company is designed to be affordable and reliable, and to meet demanding delivery requirements. Available in configurations for eight drops or fewer, each system is designed, constructed and heat tested to ensure proper performance, the company says. All systems also are fully balanced with nozzle heaters and thermocouples designed for easy maintenance.

Alba’s Quick Knockout Coupler is designed to provide a quick method of attaching the ejector plate in a mold to the ejector system in a molding machine, providing positive ejector plate return while reducing setup time. The coupler is well-suited for machines in which the ejector plate is difficult to reach, or for when center ejection is desired but impossible to “tie in.”

With its P1/... plate, machined on all sides, HASCO ensures that moldmakers benefit from the maximum possible flexibility and cost efficiency in the production of injection molds. The P1 is noted for its precision and surface finish. Customers also benefit from an optimized processing allowance as well as from tolerances that are coordinated with the latest production techniques for moldmaking.

This side-action CA locking cylinder from CB Mould Services is designed to withstand plastic injection force during the injection phase. Its compact design enables the whole part to be embedded into the cavity, reducing necessary mold dimensions and core length, and consequently reducing thermal expansion. Designed to help resolve common effects of poor cavity venting, the company’s SGD gas-venting valve allows gas to escape from a venting hole that automatically closes under the pressure of the plastic. It can be placed inside the cavity where the filling pattern produces gas traps to reduce the counter pressure of the air, improving the filling pattern.

SelfLube expanded its customization capability for bronze and steel wear strips, allowing customers to specify custom sizes, shapes, holes and hole patterns, chamfers, pockets, and cutouts.

Meusburger's two-stage ejectors are now available with DLC-coated functional surfaces. The coating minimizes wear to the surfaces and increases the durability of the ejectors, resulting in longer tool life and longer maintenance intervals. Thanks to the optimal dry-running properties of the-DLC coated functional surfaces, the twostage ejectors can be used without any lubricant, making them particularly suitable for medical and food processing applications. Required strokes are infinitely adjustable and force-controlled.
