Energy Savings

With new technology like iVG™ stack molds, plastic closure manufacturers can double production of valve gated parts without having to run additional or larger injection molding machines. This leap technology exploits the untapped potential of smaller, more efficient machines by adding a second parting line to the closure mold. The patented internal valve gate design of the new Rheo-Pro® iVG™ hot runner system now allows mold makers to build back-to-back "short stacks", compact enough to fit into smaller 180-300 ton machines.

Efficiency

Rheo-Pro® internal valve gates substantially improve the carbon footprint of the molding cell through increased energy efficiency in the heating of the hot runner system as well as the operation and production of smaller molds and machines. Energy consumption alone in a 48+48 iVG™ closure stack mold results in total cost savings of over 50% compared to a single face mold with the same number of cavities. This does not include the additional savings in productivity gains and capital equipment resulting from over 30% lower production costs.

Less Waste

Eliminating cold runners reduces waste in the form of scrap material and leads to substantial cost savings. Additionally, direct gating is extremely energy efficient and minimizes the waste that is often associated with molding micro parts, where the weight of the runner is multiple times the weight of the actual part produced. For example, composite engineering resin (30% glass fiber) used to produce this 40 mg micro part, are valuable. Direct valve gating eliminates the traditional cold runner. The cold runner to parts ratio in this application is 10:1.

All in.
