Hot Runners, Auxiliary Injection Units Enhance Control, Processing Capabilities

Mold-Masters is exhibiting hot runner systems, temperature and motion controllers, an auxiliary injection unit, a gate seal and sustainable processing solutions.

New hot runner systems on display include the Fusion Series G3 and the EcoONE Series. The Fusion Series G3 hot runner system comes pre-assembled and features compound nozzles, a heated nozzle flange, quick change headless valve pins and waterless actuators featuring passive actuator cooling technology. Alternately, the EcoONE-Series 1-8 drop hot runner system is a solution suitable for processing commodity resins for simple, cost-sensitive applications such as consumer goods, small home appliances, basic automotive components, electronic peripherals/accessories and more. It’s offered with a wide range of standard components including nozzles with a shot range capacity of <5 g up to 3,500 g in lengths ranging from 50-300 mm. Manifolds are available with custom pitch ranges.

Attendees can also see the new TempMaster M4 hot runner temperature controller and the M-Ax mold motion controller. The TempMaster M4 features Mold-Masters’ HR-Connect technology, which eliminates conventional mold thermocouple and power cables and replaces them with a single, lightweight cable connecting the mold to the control head unit. Featuring a new Mold Direct Mount design, the TempMaster M4 is claimed to set new standards for temperature controller design.

The next-generation M-Ax mold motion controller features a simplified user interface with special features, including pre-programmed mode functions and energy and torque monitoring. Energy monitoring enables molders to measure and track the energy consumption of their motion controls, while torque monitoring can be used for a variety of purposes as determined by the user.

Additional products featured include the company’s E-Multi product line of auxiliary injection units, which now includes the E-Multi mini. A compact, lightweight unit designed for small shot weights, the E-Multi mini is affixed to the mold and can be mounted in nearly any orientation. It also has a pivoting hopper that can move from left to right to accommodate challenging installation positions.

The Sprint Apex gate seal minimizes flow lines, improving environmental stress crack resistance (ESCR) of CSD caps by up to 40% to support light weighting. It is also designed to enhance part quality, improve color change by up to 65% and minimize maintenance costs by eliminating the insulation cap associated with other industry-standard gate seal designs.

The company’s various processing solutions for bio-resins and recycled materials, are also being exhibited. For example, Mold-Masters’ co-injection multilayer systems maximize the use of recycled content. The technology allows molders to incorporate recycled content up to 50% of total part weight as the core layer positioned between two layers of virgin resin.

The co-injection technology is compatible with small to large packaging products and a range of other applications. Mold-Masters offers complete system solutions and a retrofit package to convert conventional single-shot injection machines to co-injection. A system producing five-gallon pails with recycled cores on a 950-ton machine is on display and running live.
