Inserts for tunnel gates

Banana Gates

Inserts for tunnel gates

For gates that are to be cut and separated during part ejection, a tunnel gate (also called a submarine gate) is often the only design solution for injection molds with a single parting line. Furthermore, tunnel gates are especially well-suited for parts that must have a high-quality surface. For this purpose, the gate can be located on the side or back of the molded part. However, the most common type of tunnel gate encountered, often called a banana gate in the industry, is difficult to manufacture and frequently does not yield the desired results even after extensive experimentation.

Standardized inserts for tunnel gates, in either a round or rectangular shape, are now available from Hasco Hasenclever GmbH & Co KG, Lüdenscheid, Germany. According to the manufacturer, the gate inserts, which are produced by means of MIM (Metal Injection Molding), meet the demanding requirements regarding surface quality without which problem-free part ejection is not possible. The inserts (type: Z1050 and Z1060) are stocked in a number of sizes with various gate diameters. In order to optimize the gate vestige on the molded part and improve the surface quality of the part, the banana-shaped geometry can be adjusted to meet part-specific requirements. When performing maintenance, standardized gate inserts can be changed economically and quickly, reducing production interruptions associated with maintenance to a minimum.
