1 D-M-E Stack Mold Centering Devices and Mold Supports Multi-Parting Line Systems customized for your application

2 2 Mold is shown with Helical Gear centering device in closed and open positions. Stack Molds Today s plastics processor has to do more with less less labor, less capital investment, less floor space, and less time. D-M-E can help with comprehensive options for high productivity. Stack Mold Systems can double the output of standard, single face molds between the same tie bar distance. Because the cavity forces cancel each other out, the necessary clamping forces for stack molds are essentially the same as for single face molds. Key benefits of Stack Mold Systems include: Cost-effective solution for increasing capacity Optimum use of shop floor space and machine capacity Expanded molding capacity without capital expenditures More output per unit of shop floor labor higher productivity in your operation Stack Mold Systems are ideally suited for automotive applications, housewares, packaging, caps and closures, cutlery and electronic industries. Any applications that require mating parts (container and lid, top and bottom, or left and right) or strict color matching are also candidates for increased molding productivity through stack molds. Engineering Expertise Ensures Success The D-M-E design and engineering team delivers over six decades of experience with injection molding, and injection mold design. Our engineering services can quickly scale to meet the specific needs of your program. Our designers can assist in the choice and application of our rigorously engineered and proven Stack Mold Systems and Components. We can offer the entire stack mold design, configuration, and assembly including the mold base, centering and actuating components, mold carrier system hot runner system, and temperature controller. All D-M-E Stack Mold components have been designed for optimal utility and reliability. Because D-M-E delivers industry-leading expertise with Stack Mold systems, we re able to provide a worldclass, integrated solution with all systems and components operating at optimum efficiency.

3 3 Mold is shown with Rack & Gear centering device in closed and open positions. Standard Stack Mold Systems Only D-M-E offers a choice of three centering actuation systems to suit your requirements including Rack & Gear, Helical Gear and Harmonic Arms. A choice of center support configurations is available including support on the tie bars (top, bottom, or both), on the machine ways, or on both the ways and tie bars. We also offer a frictionless mold carrier, the first of its type in the industry: the Smart Line Mold Carrier System. D-M-E can further increase the efficiency of your system with our new Quick Strip System, which removes molded parts from the mold without the use of a traditional ejector system. Standard D-M-E also supplies a full line of standard. These standard components are available off-the-shelf and can be ordered for immediate shipment to meet your needs. Experienced mold designers can customize any Stack Mold system to meet their needs by using our easy to follow standards. Pre-Engineered Subassemblies Centering Devices to synchronize two or more parting line openings. Center Supports to support the center portion of the stack mold while the mold is open. Hot runner systems to deliver the plastics from the machine barrel to the cavities.
