The optimal designed part relies on the melt delivery system feeding it. The DME modular hot runner systems create uniform melt conditions to each gate to allow for pressure limitations, minimizing shear, and excellent cavity packing. The net result is a perfect plastic part produced with reliability and high efficiency.

The quality of a molded plastic part is directly related to the way the mold cavity is filled. A well designed hot runner system builds on the upfront analysis of the part design to determine, the type, number and location of the gate(s). The pressure, temperature and velocity with which a hot runner system delivers the resin into the cavity will produce optimum part quality. The part relies on the melt delivery system feeding it. A superior designed melt delivery system creates uniform melt conditions to each gate to allow for pressure limitations, minimizing shear, and providing for cavity packing. The net result is the perfect product produced with reliability and high efficiency

The Problem: Resin delivery is a precision process that often suffers due to inadequate cooling. As resin enters the mold cavity through the gate region, residual heat builds up negatively affecting the mold performance and part quality. Gate blemish such as splay or blush and even warpage often result from this excessive heat buildup at the melt entry point.

The Solution: DME has developed a low cost gate bushing which provides superior control of the nozzle tip. Regardless if it’s a bodiless, full body or even valve gate, DME’s TruCool gate bushing series can be designed into your tool before problems arise. Overcome thermal control before it becomes a concern.

DME Cooled Gate Bushing is an exciting new product designed to maximize your cooling performance. It is a standard product available off-the-shelf and can be incorporated into your initial mold design.

It’s universal fit is compatible with the today’s hot runner systems by the industry’s leading manufacturers. Customization is also possible for your preferred gating requirement. A simple installation is possible by allowing the face of the bushing to be exposed. Minimal milling will further allow a seamless solution for high profile applications.

The DME Cooled Gate Bushing has also been designed for optimal performance. Multiple options for water delivery have been designed into the product. You can choose a fixed piping into the top or sides of the bushing or, alternatively, an O-ring connection on the underside of the top flange is available.

By adding DME’s Cooled Gate Bushing, you can see molding benefits such as:

  • Reduce cycle time
  • Eliminate gate blush or splay
  • Lower sheer
  • Prolong valve gate pin and gate
  • Improve part quality
  • Minimize scrap/waste
