DME has announced the introduction of the Zenith valve gate hot runner system, which is said to suit moulders who are attempting to maintain a perfectly flat thermal profile.

According to the company, the Zenith HRS system provides improved thermal heat profiles in both the nozzle and tip, areas where uniform heat is required to help avoid flow channel hot spots.

In addition to improving the thermal profile for the new product, DME said it also focused on optimising the supply chain and its logistics to bring the system to customers more cost-effectively and with shorter lead times.

Since the system employs the company's standard DME Flex manifold heaters for improved displacement of heat, the Zenith HRS is suitable for sequential filling as well as family mould applications, according to the supplier. The benefits from the system are said to include improved part quality, reduced costs and enhanced surface finish.

Available as a hydraulic or pneumatic hot half, the company noted that it also offers front- and rear-loaded nozzle heater options for the Zenith. This system is said to work with an expansive variety of materials, and the company pointed out that it particularly suits amorphous and semi-crystalline polymers.
