Engineers choose PC when applications demand transparency, toughness, or dimensional stability.<\/p>\n<p>In our Shanghai facility, we process 400+ materials including multiple PC grades\u2014general purpose, flame-retardant, medical, and UV-stabilized variants. Each grade shifts processing windows slightly. We see flame-retardant PC needing slightly higher melt temperatures and longer cycle times due to additive content.

That combination makes it the go-to material for automotive headlight lenses, medical device housings, electronic enclosures, and safety glazing.<\/p>\n<h2>How Do You Dry PC Before Molding?<\/h2>\n<p>Dry PC at 120-150\u00b0C for 3-4 hours using desiccant drying equipment before molding. PC absorbs moisture from air and hydrolyzes if processed wet, losing molecular weight and mechanical properties. The moisture content must be below 0.02% before feeding material into the hopper.<\/p>\n<p>Voici ce qui se passe lorsque vous sautez le s\u00e9chage : l'eau r\u00e9agit avec les cha\u00eenes de PC aux temp\u00e9ratures de traitement, rompant les liaisons polym\u00e8res. Le r\u00e9sultat est une r\u00e9duction du poids mol\u00e9culaire, une perte de r\u00e9sistance aux chocs et des d\u00e9fauts de surface comme des stries argent\u00e9es ou des \u00e9claboussures. Nous voyons constamment ce mode de d\u00e9faillance \u2013 les nouvelles \u00e9quipes mettent le PC en machine \u00e0 la h\u00e2te, obtiennent des pi\u00e8ces troubles sans aucune r\u00e9sistance aux chocs, et bl\u00e2ment la qualit\u00e9 de la mati\u00e8re.<\/p>\n<p>Our standard drying protocol uses desiccant dryers at -40\u00b0C dew point. For standard PC grades, 120-130\u00b0C for 3 hours works. For high-heat or glass-filled PC, bump to 140-150\u00b0C for 4 hours. The key is maintaining temperature throughout the hopper, not just at the dryer outlet. Ambient moisture reabsorbs quickly\u2014leaving dried pellets exposed for even 30 minutes can push moisture back up.<\/p>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets.webp\" alt=\"polycarbonate-pc-material-pellets\" style=\"max-width:100%;height:auto;\" class=\"wp-image-52482\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets.webp 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets-300x171.webp 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets-768x439.webp 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets-18x10.webp 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-pc-material-pellets-600x343.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">Polycarbonate resin pellets<\/figcaption><\/figure>\n<p>Astuce pratique : utilisez un analyseur d'humidit\u00e9 ou un simple humidim\u00e8tre pour v\u00e9rifier le s\u00e9chage avant le d\u00e9but de la production.

The exact melt temperature depends on flow length, part thickness, and PC grade. Mold temperature affects crystallinity and stress levels\u2014higher temperatures reduce residual stress and improve optical clarity.<\/p>\n<p>Starting point: 290-300\u00b0C melt, 90-100\u00b0C mold for most general-purpose PC parts. If you see incomplete fills or flow marks, increase melt temperature in 5-10\u00b0C increments up to 310\u00b0C maximum. If you see degradation, discoloration, or gas marks, reduce melt temperature. The window is narrower than for ABS or PP\u2014too cold gives short shots, too hot degrades material rapidly.<\/p>\n<p>Mold temperature is often overlooked but critical for PC. Cold molds (below 60\u00b0C) cause high residual stress, warpage, and poor surface finish. Hot molds (above 120\u00b0C) extend cycle time and can cause sticking. We run most PC tooling at 90-110\u00b0C using circulating oil or cartridge heaters. For optical parts demanding clarity, push mold temperature to 110-120\u00b0C.<\/p>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured.webp\" alt=\"polycarbonate-injection-molding-featured\" style=\"max-width:100%;height:auto;\" class=\"wp-image-52481\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured.webp 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured-300x171.webp 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured-768x439.webp 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured-18x10.webp 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/03\/polycarbonate-injection-molding-featured-600x343.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">Polycarbonate injection molding product<\/figcaption><\/figure>\n<p>La mont\u00e9e en temp\u00e9rature est \u00e9galement importante.

Cela donne au PC le temps de stabiliser l'homog\u00e9n\u00e9it\u00e9 de la fusion avant d'entrer dans le moule.<\/p>\n<p>La surveillance est essentielle. Utilisez des capteurs de temp\u00e9rature de fusion et des contr\u00f4les de viscosit\u00e9 p\u00e9riodiques pour v\u00e9rifier que votre temp\u00e9rature de fusion r\u00e9elle correspond aux r\u00e9glages machine.

Mold surface finish affects optical clarity\u2014mirror polish yields transparent parts, while textured surfaces scatter light for diffuse appearance.<\/p>\n<p>Wall thickness uniformity is non-negotiable for PC. Abrupt thickness changes cause differential cooling, leading to warpage, sink marks, and internal stress. If your design requires varying thickness, transition gradually over a distance at least three times the thickness difference. For a jump from 2mm to 4mm, maintain a ramp of at least 6mm transition length.<\/p>\n<p>Gate design deserves attention. PC has high viscosity, so gate size matters more than for lower-viscosity resins. Use edge gates of 1.0-1.5mm thickness for parts up to 3mm wall thickness. Submarine or tunnel gates of 0.8-1.2mm diameter work for smaller parts. Hot runners are excellent for PC\u2014they reduce material waste and provide better temperature control, but require higher upfront investment.<\/p>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage.webp\" alt=\"Collage of plastic injection molded automotive parts\" style=\"max-width:100%;height:auto;\" class=\"wp-image-53475\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage.webp 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage-300x171.webp 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage-768x439.webp 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage-18x10.webp 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-parts-collage-600x343.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">Automotive PC injection molded parts<\/figcaption><\/figure>\n<p>Ventilation is critical.

Poor venting causes burn marks, gas traps, and incomplete fills even with correct injection parameters.<\/p>\n<p>Ejector design requires care. PC parts can be stubborn and mar easily. Use ejector pins of at least 5mm diameter with smooth, rounded ends. Add stripper plates or air ejection for large, flat parts.

Surface finish helps hide minor flow marks\u2014textured surfaces conceal these defects better than glossy finishes.<\/p>\n<div class=\"claim claim-true\" style=\"background-color: #eff7ef; border-color: #eff7ef; color: #5a8a5a;\">\n<p><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#16a34a\" stroke-width=\"2\"><path d=\"M9 16.17L4.83 12l-1.42 1.41L9 19 21 7l-1.41-1.41z\"\/><\/svg><b>\u201cLes stries argent\u00e9es dans les pi\u00e8ces en PC indiquent g\u00e9n\u00e9ralement un s\u00e9chage insuffisant.\u201d<\/b><span class=\"claim-true-or-false\">Vrai<\/span><\/p>\n<p class=\"claim-explanation\">Moisture in PC vaporizes at melt temperatures, creating gas bubbles that appear as silver streaks on the part surface.

The optimal mold temperature balances quality and efficiency.<\/p>\n<\/div>\n<h2>How Do You Optimize PC Processing Parameters?<\/h2>\n<p>Optimize PC processing by setting injection speed to medium-fast for filling, using a packing pressure of 50-80% of injection pressure for 2-4 seconds, maintaining cooling time based on wall thickness at approximately 10-12 seconds per mm, and back pressure of 50-150 bar to improve melt homogeneity. Screw speed of 50-100 RPM provides adequate mixing without excessive shear heating.<\/p>\n<p>Injection speed affects part quality significantly. Too slow causes material to freeze prematurely, resulting in short shots or weld lines. Too fast causes jetting, high shear heating, and potential degradation. Start at medium speed and adjust based on part appearance. For thin-walled parts needing long flow, push speed higher. For thick parts where flash is a concern, reduce speed.<\/p>\n<p>Packing pressure compensates for shrinkage as the material cools. PC has relatively low shrinkage (0.5-0.7%), but packing still matters for dimensional accuracy. Start packing at 60% of injection pressure for 3 seconds, then adjust. Too little packing causes sink marks and dimensional undershoot. Too much packing creates flash, high residual stress, and can even cause ejection problems.<\/p>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts.webp\" alt=\"Plastic injection molded car parts\" style=\"max-width:100%;height:auto;\" class=\"wp-image-53476\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts.webp 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts-300x171.webp 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts-768x439.webp 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts-18x10.webp 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/plastic-injection-molded-car-parts-600x343.webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">Automotive PC injection molded parts<\/figcaption><\/figure>\n<p>Cooling time depends primarily on wall thickness but also on mold temperature. A rough guideline: 10-12 seconds per mm of wall thickness for PC. A 3mm wall needs roughly 30-36 seconds cooling time.

The combination of optical properties, toughness, and heat resistance makes PC versatile across industries.<\/p>\n<p>Automotive applications dominate PC usage. Headlight lenses, fog light covers, and taillight assemblies require transparency and impact resistance. PC withstands UV exposure (with appropriate stabilizers) and maintains clarity at elevated temperatures under the hood. We mold automotive light components with tight optical specifications\u2014transmission above 88% and yellowness index below 2.0.<\/p>\n<p>Les applications \u00e9lectroniques et \u00e9lectriques utilisent le PC pour les bo\u00eetiers, connecteurs et composants n\u00e9cessitant une r\u00e9sistance au feu.

The moisture content must reach below 0.02% to prevent hydrolysis during melt processing. Higher drying temperatures (140-150\u00b0C) are needed for glass-filled or high-heat PC grades. Never rely on ambient drying or skip drying steps\u2014this is the single most common cause of PC part failure. Use a desiccant dryer with -40\u00b0C dew point and verify moisture content with a moisture analyzer before production starts. Even dried PC reabsorbs moisture quickly when exposed to air, so keep hopper lids closed and material sealed.<\/p>\n<h3>What is the ideal melt temperature for PC injection molding?<\/h3>\n<p>The ideal melt temperature for PC ranges from 280-310\u00b0C depending on the grade and part geometry. General-purpose PC typically processes at 290-300\u00b0C. Flame-retardant or glass-filled grades may require slightly higher temperatures up to 310\u00b0C. Exceeding 310\u00b0C risks thermal degradation and discoloration. Start at 290\u00b0C and adjust in 5-10\u00b0C increments based on part fill appearance and surface quality. Use a gradual temperature profile across the barrel zones to ensure uniform melting without thermal shock. Monitor for signs of degradation like yellowing or gas marks.<\/p>\n<h3>What mold temperature is best for PC parts?<\/h3>\n<p>Optimal mold temperature for PC is 80-120\u00b0C, with 90-110\u00b0C being the typical range for most applications. Higher mold temperatures (110-120\u00b0C) reduce residual stress and improve optical clarity for transparent parts. Lower mold temperatures (80-90\u00b0C) provide faster cycle times but may increase warpage risk. Adjust based on part requirements\u2014optical parts need hotter molds than opaque components. Circulating oil or cartridge heaters provide uniform temperature control for PC tooling. Cold molds below 60\u00b0C cause high residual stress and poor surface finish results.<\/p>\n<h3>Why do PC parts have silver streaks on the surface?<\/h3>\n<p>Silver streaks or splay on PC parts indicate moisture in the material, typically from insufficient drying. Even dried PC can reabsorb moisture if left exposed to ambient air. Ensure desiccant drying at 120-150\u00b0C for 3-4 hours with a -40\u00b0C dew point dryer. Verify moisture content is below 0.02% before molding. Check dryer function and keep hopper lids closed to prevent moisture reabsorption. Silver streaks are the most visible sign of moisture-related hydrolysis during melt processing. This is the most common PC failure and requires immediate drying verification.<\/p>\n<h3>What causes warpage in PC injection molded parts?<\/h3>\n<p>Le voilage du PC r\u00e9sulte principalement d'un refroidissement non uniforme, d'une \u00e9paisseur de paroi variable ou de contraintes r\u00e9siduelles \u00e9lev\u00e9es. Assurez une \u00e9paisseur de paroi uniforme avec des transitions douces (ratio 3:1) et des canaux de refroidissement ad\u00e9quats. Augmentez la temp\u00e9rature du moule de 10 \u00e0 20\u00b0C pour r\u00e9duire les contraintes r\u00e9siduelles. V\u00e9rifiez que le temps de refroidissement est suffisant pour les sections les plus \u00e9paisses. Parfois, ajuster l'emplacement de la porte ou ajouter des guides d'\u00e9coulement aide \u00e0 \u00e9quilibrer les vitesses de refroidissement sur la pi\u00e8ce. Le voilage s'aggrave souvent avec le temps si les contraintes r\u00e9siduelles ne sont pas g\u00e9r\u00e9es pendant le moulage. Utilisez une analyse d'\u00e9coulement dans le moule pour identifier les zones potentielles de voilage avant l'outillage.<\/p>\n<h3>Can PC injection molding produce transparent parts?<\/h3>\n<p>Yes, PC injection molding can produce transparent parts with light transmission up to 90%. Transparency requires high mold temperatures (110-120\u00b0C), proper drying to prevent splay, and highly polished mold surfaces. The mold surface finish directly transfers to the part\u2014mirror-polished cavities yield clear parts, while textured surfaces create diffuse or translucent appearance. Avoid scratches or imperfections in the mold that will affect optical quality. Use PC grades specifically formulated for optical applications rather than general-purpose resin. Monitor yellowness index to ensure consistent clarity.<\/p>\n<h3>What is the shrinkage rate of PC in injection molding?<\/h3>\n<p>PC has a typical shrinkage rate of 0.5-0.7%, which is relatively low compared to semi-crystalline materials. The low shrinkage helps dimensional accuracy but does not eliminate the need for proper processing. Packing pressure, cooling time, and mold temperature all affect final dimensions. Use standard shrinkage values for initial mold design but validate actual shrinkage during T1 sampling with the specific PC grade. Different PC grades may have slightly different shrinkage characteristics. Measure shrinkage in flow and transverse directions as they can vary.<\/p>\n<p>Quick rule: Dry PC at 120-150\u00b0C for 3-4 hours, run melt at 290-300\u00b0C, keep mold at 90-110\u00b0C, and maintain uniform wall thickness. If you see silver streaks, check drying. If parts warp, balance cooling. If dimensions drift, adjust packing. Master these basics, and PC becomes a reliable workhorse rather than a problematic material.<\/p>\n<p>Dans notre usine de Shanghai, avec 45 machines de moulage par injection et plus de 20 ans d'exp\u00e9rience depuis 2005, nous transformons du PC quotidiennement pour des applications automobiles, \u00e9lectroniques et m\u00e9dicales.
