Thermoplastic injection molding is a method for manufacturing high-volume parts with plastic materials. Due to its reliability and flexibility in design options, injection molding is used in many industries, including: packaging, consumer & electronics, automotive, medical, and many more.
Forming technique for producing small components using powders, typically ceramics (CIM) or metals (MIM), and binding agents.
What are some advantages of injection molding?
Injection molding manufactures high quantities of parts, faster than other manufacturing methods (machining or 3D-printing). High accuracy and automated processes encourage identical part creation, promoting low labor costs. Customization allows flexibility in part design (ex. molded-in inserts) and material properties (ex. color, clarity, strength, & flexibility).
What challenges can appear with injection molding?
Part designers, mold engineers, and other manufacturing stakeholders can all run into their own challenges, which ultimately affect part quality, and they often need to work together to resolve if not caught in the early design stages.
Some examples of these challenges include material variations, weld lines, sink marks, warpage, long cycle times, and incomplete cavity filling.
How does injection molding simulation software help?
Molding simulation can help designers and engineers to understand risks early in the design process, allowing the ability to address these before becoming fully invested. Simulation software gives engineers, mold makers, and other molding professionals accurate digital prototyping solutions, and help bring better products to market faster.
Moldflow simulation can be paired with other simulation tools, including mechanical stress, vibration, motion, computational fluid dynamics (CFD), and Multiphysics, providing a fast, accurate, and innovative approach to solving the most challenging design problems.
