ADVANTAGE - ZERO CONTACT DURING SEGMENT MOVEMENT
LARGE SEGMENTS LEAD (Outer part of DURA Core) Material: S136/420/Equivalent Hardness : 50-54HRC
SMALL SEGMENTS (Inner part of DURA Core) Material: S136/420/Equivalent Hardness : 50-54HRC
LARGE SEGMENTS LEAD During the mold closing phase, the center core first engages larger segments, designed to make contact before the smaller ones. This allows larger segments to smoothly lead the opening, ensuring efficient and contact-free movement. SMALL SEGMENTS FOLLOW Following the larger segments, the center core smoothly engages the smaller ones, ensuring their synchronized and coordinated efforts. This designpre - vents contact and additional load on the smaller segments during the mold closing phase. ZERO CONTACT DURING MOTION In the DURA CORE, the absence of physical contact between large and small segments markedly decreas- es wear and tear. This essential innovation is key to ensuring a longer operational life for the DURA CORE.
SAFETY RING (Mounted on a safe plate) Material: D2 Hardness : 58-60HRC
STRAIGHT CORE PIN (Mounted on a fixed plate) Material: D2 Hardness : 58-60HRC
Note: Safety ring is not necessary if the collapsible core diameter is equal to or greater than 40mm. Omitting the safety ring in these cases simplifies the mold design and the ejection process.
DURA CORES CAN BE ORDERED WITH OR WITHOUT DLC COATING AND CORE MATERIAL CAN BE CHANGED BASED ON THE APPLICATION.
WITH PATENTED TWO-PIECE DESIGN The two-piece design of the DURA CORE is an innovative feature that significantly enhances the usability and maintenance of the collapsible core in injection molding. • Effortless Disassembly: Simplifies the process, enabling quick access to each component. • Easy Inspection and Cleaning: Offers enhanced accessibility for thorough maintenance • Rapid, Secure Reassembly: Ensures quick and correct reassembly after maintenance • Minimize Maintenance Downtime: Reduces maintenance time, boosting production ADDITIONAL DESIGN FEATURES • Short Safety Ring: A compact safety ring, securely mounted on a safe plate
MULTIPLE VERSIONS DEPENDING ON PART GEOMETRY The DURACORE can be designed with diverse segment options, providing design flexibility to ensure sufficient collapse for undercuts. The number of segments required is determined by the part size, part shape and the undercut. We offer options of 8, 10, 12, and 16 segments to accommodate a broad spectrum of part sizes, with diameters ranging from 15mm to 150mm.
• Straight Core Pin: The straight core pin design is a key element in optimizing both manufactur- ing and cooling. By facilitating more efficient cooling, it leads to improved overall performance of the core, enhancing the quality of the molded parts. • Reduced Overall Length: The DURA core's reduced length offers considerable space-saving advantages. This design aspect is particularly beneficial in minimizing the mold base stack height, leading to more compact and efficient mold designs. • Compact Footprint: A space-efficient design allows for more cavities in the same-sized molds or the same number of cavities in a smaller mold, thereby maximizing production output per cycle.
