We need to carefully evaluate the properties of each thermoplastic prior to initiating the mold design process. Among these thermoplastic, polycarbonate, acrylic, and polystyrene are the mainstream materials employed in injection molding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Polycarbonate_PC\"><\/span><strong>\u25cf Polycarbonate (PC)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Polycarbonate is a widely used material in precision injection molding, particularly valued for its exceptional optical properties. Not only is it a prevalent choice for injection molding, but its optical characteristics are also noteworthy. With a refractive index of approximately 1.59 and an 84% transmission of visible light alongside a 74.3% UV transmission rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Acrylic_PMMA\"><\/span><strong>\u25cf Acrylic (PMMA)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Acrylic is another material frequently utilized not just in injection molding, but also in various manufacturing processes like CNC lathe and milling, thanks to its superior mechanical properties. Additionally, acrylic offers unique optical characteristics. It boasts a refractive index of approximately 1.49 and an 83.1% transmission rate of visible light. Unlike polycarbonate, however, acrylic has a UV transmission rate of just 4.82%, effectively blocking nearly all UV light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Polystyrene_PS\"><\/span><strong>\u25cf<\/strong> <strong>Polystyrene (PS)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Polystyrene is ideally suited for precision molding, thanks to its low shrinkage which enables designers to craft intricate and detailed items.

The mechanical properties of materials play a vital role in producing optical lenses in injection molding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Thermal_expansion\"><\/span><strong>\u25cf<\/strong> <strong>Thermal expansion<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Thermal expansion of materials can interfere with the alignment between the guidepost and guide bush, impede the smooth movement of the slide core, or increase the dimensions of the core pins.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Operating_Temperature\"><\/span><strong><strong>\u25cf<\/strong> Operating Temperature<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The term &#8222;operating temperature&#8220; typically refers to two key temperatures in the context of materials: the <strong>melt temperature <\/strong>and the <strong>mold temperature<\/strong>. The melt temperature is the temperature at which plastic materials melt within the <a href=\"https:\/\/www.thy-precision.com\/in-depth-look-at-injection-molding-machine-types-uses\/\" target=\"_blank\" rel=\"noreferrer noopener\">injection molding machine<\/a>. <\/p>\n\n\n\n<p>Setting this temperature correctly is crucial and depends on the specific type of plastic. It ensures that the material melts completely and flows properly. The mold temperature, on the other hand, relates to the surface temperature of the mold, controlled through a temperature control system. <\/p>\n\n\n\n<p>Optimizing the mold temperature is necessary to align with the properties of the injection molding materials and the specifications of the final product. Different materials require varying melt and mold temperatures, as detailed in the table below:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><\/td><td>Melt Temperature<\/td><td>Mold Temperature<\/td><\/tr><tr><td>Polycarbonate (PC)<\/td><td>302 \u00b0C<\/td><td>83.6 \u00b0C<\/td><\/tr><tr><td>Acrylic (PMMA)<\/td><td>227 \u00b0C<\/td><td>63.3 \u00b0C<\/td><\/tr><tr><td>Polystyrene (PS)<\/td><td>217 \u00b0C<\/td><td>37.1 \u00b0C<\/td><\/tr><tr><td>Cyclic-olefin polymer (COP)<\/td><td>251 \u00b0C<\/td><td>100 \u00b0C<\/td><\/tr><tr><td>Cyclic-olefin copolymer (COC)<\/td><td>190 \u00b0C ~ 301\u00b0C<\/td><td>40 \u00b0C ~ 170 \u00b0C<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%97%8F_Water_absorption\"><\/span><strong>\u25cf<\/strong> <strong>Water absorption<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Water absorption increases the risk of molding defects and can compromise the tensile and impact strength of plastic products. Therefore, it is vital to adequately dry the material prior to production to sidestep these complications. Establishing the correct drying time and temperature is a key part of this preventive measure.<\/p>\n\n\n\n<p>In addition to focusing on material properties, we prioritize our clients&#8216; needs.
