Secondary, post-molding operations are sometimes necessary to complete the assembly.Why Choose PMC? Plastic injection molding has brought about a manufacturing revolution, enabling the creation of intricate components with unparalleled efficiency. However, even this advanced technique is not immune to challenges, and issues may arise that lead to product failures. In such cases, conducting a comprehensive product failure analysis becomes crucial in order to get your product back on the market quickly with every chance the product will live up to a reasonable expectation of a long market presence. Thermoplastic materials are widely used in injection molding due to their ability to be melted and reshaped multiple times. This property makes them highly recyclable and suitable for applications requiring post-consumer recycled content or flexible manufacturing processes. Injection molding offers flexibility in materials, allowing manufacturers to choose from a wide range of thermoplastics, thermosets, and elastomers, each with specific properties like toughness, heat resistance, or flexibility, suited to different end-use applications.
Choosing a North American supplier, like Rex Plastics, for your injection molding needs offers several significant advantages that can enhance your manufacturing process Semi-crystalline polymers, such as nylon or polypropylene, exhibit different cooling behaviors compared to amorphous plastics. These materials require careful control of cooling rates to prevent warping, internal stresses, or incomplete crystallization during the injection molding process. In addition, glass fill percentages can range quite a bit (typically 13% to 45%), which will affect the final part’s properties accordingly.Uniform Wall ThicknessNo Sharp, 90-degree AnglesFew Through Holes & TurnsNon-complex GeometriesGate Location at the Long Axis of the Part Poor specification & improper material selection is the leading cause of failure in plastic injected molded parts, followed by improper plastic injection mold design and processing practices.
The integration of sustainable practices in injection molding processes reflects a growing commitment to environmental stewardship. By prioritizing eco-friendly materials and practices, manufacturers can contribute to a more sustainable future. Shrinkage compensation is a vital part of mold design, especially for materials with high shrinkage rates, to avoid dimensional inaccuracies in the final part. PMMA is an economical material used for applications
requiring excellent optical, light, transmittance, and weatherability. Common products
include lighting and optical applications. PMMA is sometimes referred to as
acrylic glass as it is a lightweight, shatter-resistant alternative to glass. Advantages
include: Resistance to UV radiation and weatheringHigh refractive index and clarityGreat light transmissibility (white light
transmittance can be as high as 95%)Has the greatest surface hardness of any
plastic, making it scratch resistantDyes can be added to get a certain colorChemical resistance Mold cooling time is often the longest part of the cycle, so optimizing cooling channels and using efficient heat transfer materials can dramatically improve cycle times. Plastic Molded Concepts provides medical plastic injection molding for components used in end-use medical devices and complex assemblies within different systems. In addition to providing overmolding services, we also offer a comprehensive range of other plastic molding services including mold design assistance, modeling, prototyping, manufacturing, and testing.
