steven's blog for plastic mold and plastic molding

Like a successful play in football, successful plastic injection molding product design and production requires team effort and a well-developed strategy. When designing plastic parts, your team should consist of diverse players, including conceptual designers, stylists, design engineers, materials suppliers, mold makers, manufacturing personnel, processors, finishers, and decorators. Your chance of producing a product that successfully competes in the marketplace increases when your strategy takes full advantage of team strengths, accounts for members’ limitations, and avoids overburdening any one person. As the designer, you must consider these factors early in strategy development and make adjustments based upon input from the various people on the design team. Solicit simultaneous input from the various “players” early in product development, before many aspects of the design have been determined and cannot be changed. Accommodate suggestions for enhancing product performance...

Husky Injection Molding Systems launched its new Ultra SideGate hot runner technology at October's Fakuma International Trade Fair, where it was received "extremely positively," according to Martin Baumann, Husky's Business Manager, Hot Runners. Husky has started shipping its first systems to customers. The new hot runner is designed and optimized specifically for deep-draw parts for the medical device industry such as pipettes, syringe barrels and other small applications. It allows customers to direct gate parts that would otherwise require gating with a cold runner, making this new technology particularly valuable in the manufacture of injection molding parts where quality and gate vestige are critical. Husky's Ultra SideGate hot runner targets deep-draw parts with high quality and gate vestige requirements. Ultra SideGate allows for high-cavitation molds with a small footprint, while providing outstanding gate quality and offering moldmakers added design flexi...

demonstration of Sigmasoft at the K show, Kruse was impressed. "I was using a different software at the time, but I clearly identified what simulation software should provide. Sigmasoft was way beyond anything I'd ever seen," he states. "I had the pleasure of working with Sigmasoft for several years prior to their opening their own North American office. I have been using the Sigmasoft software ever since." "Pretty awesome" Rick Finnie, president of M.R. Mold & Engineering, remarks that the Sigmasoft molding analysis software is "pretty awesome," and does what it does "on a higher level than currently exists by using a 3D mesh." Sigmasoft molding analysis software takes the model and breaks it into tiny elements and runs the mathematical calculations to determine a vast variety of processing results. "We've used it a few times and it's amazing what it can tell us," Finnie says. Kruse notes that if the analyst d...

Currently, Rick Finnie is working on a thermoplastic injection molded part (M.R. Mold & Engineering is also known for its expertise in liquid silicone rubber (LSR) molds). The product is a secure lock box for the medical industry that requires tamper proofing. "The door is a highly visible part, so a direct sprue gate couldn't be used, which would be the usual choice," explains Finnie. "The second choice was to put the gate at the end of the door, but that would have required a 10-inch runner, so we had concerns with a side edge gate. There were just a lot of issues so we chose to have Kruse Analysis do a filling analysis for us." Initially Finnie thought the gate location he chose was "a terrible location" but the wall thickness at that site allowed the part to fill without flow or knit lines. The analysis also showed that the gate and sprue were freezing before the part was fully packed. Finnie's team redesigned the gate and sprue. Additional...

The characteristic being the modern plastic mold , having the intensive handicraft industry under the high technology , concentrated , high technology of talented person background, is to walk on the new road to industrialization in preceding estate , the plastic mold is equipped with industry as important fabrication while being all professions and trades service , serve also directly for high and new technology industries, the plastic mold grinds hair in manufacturing industry product , FOAK and childbirth are hit by what be had distinctive important position, feasible plastic mold manufacturing capability and horizontal height also become important national innovating capacity sign. The plastic mold is to be equipped with a guarantee in order part forming of all kinds provides a handicraft , development of simultaneous plastic mold technology is that technology development spurs on by forming part , the innovative product is also to need to come to come true by new handicraft of pl...

After plastic mold is ready,Splicing is arguably the most mature and simplest ways of fabricating or fastening two injection molding pieces together. Infact, splicing methods have been known even before other methods like welding, bolting or soldering. The concept of splicing involves the connection of pieces by using the surface adhesion between the plastic molding parts and the adhesives’ firmness or cohesiveness. One of the best features in splicing is an even distribution of stress. In addition, other benefits are that totally different materials can be brought together, large splicing areas can be made quickly, and the adhesive itself fills uneven surfaces. Nevertheless, splicing also involves certain pitfalls. In certain cases, the strength is limited and not all materials are suitable for splicing (Polyolefins), and proper storage of the chemicals is vital. Changes in temperatures will render problems for moist adhesives. Also, a different expansion between the plastic and the...

Two-shot silicone-thermoplastic injection molding is a method to create a silicone-and-thermoplastic part in one process. These parts are traditionally plastic molding individually and assembled as one medical device component. The two-shot process eliminates secondary operations and assembly, which are often the main contributors to increasingly higher part costs. By reducing the chance of misalignments seen in traditional inserts or in overmolding processes, the two-shot process enables improved performance and consistent quality. The process offers the ability to produce complex mouldings from two different polymers at the same time during one machine cycle. Separate, but compatible, materials or colours are chemically bonded or mechanically interweaved during the forming process when the second material is injected into the mould, which avoids the need for further assembly or postprocessing. Alternatively, incompatible materials can be mechanically connected by two-shot moulding ...
