After degating the acrylic mold, you need to remove excess materials from the sides of the mold. The excess materials can be in the form of flash, or excess compounds and resin bleeds. You can remove them through the process of deflashing to eliminate imperfections on the acrylic mold.
Clear plastic molding parts can be made from a wide range of plastic materials, including polycarbonate, acrylic, PET, and PVC. The choice of material will depend on the specific application and the desired properties of the part, such as strength, temperature resistance, and chemical resistance.
19 Δεκ 2023 · You’ll want to choose materials that are inherently clear, such as acrylic and polycarbonate, which allow for maximum transparency and minimal haze. Factors like wall thickness must be carefully managed to prevent defects like sink marks, which can detract from clarity.
7 Σεπ 2022 · Popular materials for clear plastic injection molding include: Acrylic, HDPE, Polycarbonate, and PEI; SPI-A2 is the best surface finish for optimal clarity; Maintaining uniform wall thickness will provide best results for clear parts
Mould materials for clear plastic molding are: NAK80,1.2344ESR,S136,S-STAR. Use the right steel for clear plastic part mould building. NAK80, P20HH, 1.2344ESR, S136, S136H, and S-STAR are the most common steels used by GREFEE for cavities and cores.
Acrylic, or Plexiglass, is a PMMA material with a transmittance of up to 92%, which is higher than glass, making acrylic molding one of the best solutions for high-requirement precise injection molding components such as glass, optical glass, lenses, vehicle lights, transparent pipes, and so on.
9 Απρ 2024 · The Importance of Design. Designing for clarity requires a meticulous approach. Uniform wall thickness, strategic gate placement, and careful consideration of the cooling and contraction processes are fundamental to avoiding defects and distortions in clear plastic molding.
