Inline Hot Runner Tech Benefits Injection Molding Operations

10 October 2017

Husky Injection Molding Systems (Bolton, ON, Canada), a technology provider to the plastics processing Source: Husky Injection Molding SystemsSource: Husky Injection Molding Systemscommunity, announces the commercial release of its Ultra SideGate™ Inline hot runner technology. The Ultra SideGate Inline hot runner was designed and optimized for challenging applications with high-balance requirements such as long, thin parts and is ideal for part spacing as low as 18 mm. By taking advantage of the optional individual tip control technology, molders can ensure that their challenging applications have the best part quality possible.

The new Inline option provides all of the same benefits and features of Husky’s standard Ultra SideGate, which allows for high cavitation molds with a small footprint, reducing cost while providing outstanding gate quality and offering mold makers added design flexibility.

By direct-gating parts with Ultra SideGate, molders can achieve significant resin savings, faster cycle times and better performance across a wider temperature range. In addition, the technology allows direct access to the individual tips without needing to remove the mold from the injection molding machine, saving molders time on maintenance.

Ultra SideGate Inline offers exceptional gate quality leaving virtually no vestige on finished parts (~0.05 mm vestige). By allowing for the use of a single-piece cavity in the design of the mold, the quality issues that often accompany split cavity designs are avoided, such as flash on finished parts that can occur if the cavities are misaligned. This is particularly critical in the medical industry where safety is paramount and sharp edges can be detrimental. Ultra SideGate Inline is also ideal for complex applications that require technical resins such as automotive connectors.

The product is simple to install and easy to maintain. Nozzle tips are mounted separately from the nozzle housing into one-piece cavity inserts before hot half assembly. This approach eliminates the impact of thermal expansion on tip position, which can impact balance and gate quality.

To minimize footprint and allow for the maximum number of mold cavities in the smallest mold, Ultra SideGate Inline offers pitch spacing down to 18 mm. It also includes patented UltraSeal® technology with three-year leak-proof guarantee, and performs consistently with a wide variety of challenging resins.
