If end use permits, ejector pin mark flash will not be removed. Ejector pin marks are surrounded by a flash of metal. Acceptable Ejector Pin MarksĮjector pin marks on most die castings may be raised 0.38mm maximum or may be depressed 0.38mm maximum. Location of Ejector PinsĮjector pin locations shall be at the option of the die caster subject to the customer’s agreement where required. The values shown for hole depths are subject to the draft requirements. Visit for more information.Optimum greatest depth of cored holes as related to diameter is shown in the table. A subsidiary of Milacron, Inc., D-M-E also manufactures and sells standard tooling for the die-casting industry. The company's standard-setting, comprehensive product line-including hot runner systems control systems mold bases and components mold making and molding supplies and cold runner systems for elastomers - is backed by expert technical service every step of the way. Through aggressive new product development, global product standardization and a powerful combination of in-house manufacturing centers of excellence and strategic global partnerships, D-M-E is helping customers succeed in changing times. Machining and maintenance time is cut in half and costs for the Quick Strip versus traditional ejector equipment are over 20 percent lower, leading to more profitable and faster turnaround projects and helping customers again be more competitive in the challenging marketplace.ĭ-M-E Company is an essential mold technologies resource to customers worldwide. This addition to D-M-E's ever growing line of global off-the-shelf products is available in three standard sizes and promises significant savings. The patent-pending Quick Strip has been tested extensively and can be used with many applications. We achieved higher surface quality using Quick Strip and reduced the mold construction time and costs considerably in the process." "We were molding parts for the Airbus and because of aesthetic requirements, ejector pin marks can't be visible. "We were immediately interested when D-M-E presented the new Quick Strip concept to us," said Dirk Schmeling, general manager at Deva Kunststoff-Technik GMBH. Molder/moldmaker Deva of Lemgo, Germany, and OEM Hans Kroner Formenbau of Schloss Holte-Stukenbrock, Germany, used the Quick Strip on their last project making parts for the Airbus A380 for that very reason. Because the Quick Strip "lifts" the part from the mold cavity rather than pushing it like an ejector pin, there are no marks left on the part. "This is the perfect example of D-M-E and industry inventors coming together to commercialize a product that is essential to the continued success of our customers and their competitiveness in the industry."īeyond cost and time savings, the Quick Strip offers cosmetic advantages for parts where aesthetics is a critical factor. "The Quick Strip introduction is part of our new approach to product development," said Bob McKee, president of D-M-E Company. He devised this system and found it saved him 50 percent on his mold costs. This revolutionary concept in part ejection technology was conceived by a German moldmaker looking for ways to be more competitive. With the absence of ejector pin holes as obstacles, cooling systems can also be optimized leading to faster cycle times. Implementing a Quick Strip eliminates the need for ejector plates and pins, risers and clamping plates, resulting in lower part costs, machining and maintenance. Since its introduction to the market in late 2008, the Quick Strip has received a great deal of interest from moldmakers and is gaining momentum as the next great innovation in part ejection. Attendees can visit D-M-E in the West Hall at Booth # 103000 to see this global, standardized off-the-shelf product that significantly reduces mold construction time and costs. D-M-E Company is pleased to feature at NPE 2009 the newest innovation in mold making part ejection, the Quick Strip.
