It handles continuous temperatures up to 250 degrees C, passes USP Class VI biocompatibility testing, and resists chemical attack from sterilization processes. Processing requires barrel temperatures of 370 to 400 degrees C and mold temperatures of 160 to 200 degrees C. Temperature control within plus or minus 2 degrees C is critical \u2014 a 5 degree drift can cause 30 percent dimensional variation in a micro PEEK part.<\/p>\n<p>POM (acetal) is the workhorse for mechanical micro parts like gears, bushings, and snap fits. It machines well in the mold, has low friction, and holds tolerances consistently. Medical-grade ABS rounds out the common choices for housings and enclosures where biocompatibility is required but extreme temperature or chemical resistance is not.<\/p>\n<h3>How to Select the Right Material for Micro Parts<\/h3>\n<p>Choosing the right material also depends on secondary operations. If the micro part requires ultrasonic welding, only certain grades of ABS and PMMA bond reliably at the joint interface. For laser welding, the material pair must have different absorption characteristics \u2014 typically a carbon-loaded base with a natural-color lid. These constraints are often overlooked in the design phase and can force a material change late in development.<\/p>\n<p>Processing windows for micro molding materials are significantly narrower than for standard molding. A typical POM gear might tolerate plus or minus 10 degrees C barrel temperature variation at normal scale, but the same material in a micro part requires control within plus or minus 3 degrees C. Dedicated micro molding machines feature multiple barrel temperature zones with independent PID controllers and thermocouple feedback every 50 mm along the barrel length.<\/p>\n<div class=\"factory-insight\" data-fact-ids=\"equipment.injection_machines_47,equipment.tonnage_90_1850,location.shanghai_factory,company.experience_20_years,materials.material_range_400_plus\" style=\"background:#f0f7ff;border-left:4px solid #0066cc;padding:12px 16px;margin:1.5em 0;\"><strong>\ud83c\udfed ZetarMold Factory Insight<\/strong><br \/>ZetarMold\uc758 \uc0c1\ud558\uc774 \uacf5\uc7a5\uc5d0\uc11c\ub294 90T\uc5d0\uc11c 1850T\uae4c\uc9c0\uc758 47\ub300 \uc8fc\uc785 \ubab0\ub529 \uae30\uae30\uac00 \ud504\ub85c\ud1a0\ud0c0\uc785 \uc2e4\ud589\ubd80\ud130 \ub300\ub7c9 \uc0dd\uc0b0\uae4c\uc9c0\uc758 \ub9c8\uc774\ucf54 \ubab0\ub529 \ud504\ub85c\uc81d\ud2b8\ub97c \uc9c0\uc6d0\ud569\ub2c8\ub2e4. \uc6b0\ub9ac\uc758 20\ub144 \uc774\uc0c1\uc758 \uc8fc\uc785 \ubab0\ub529 \ubc0f \ub3c4\uad6c \uacbd\ud5d8\uacfc 400\uc885 \uc774\uc0c1\uc758 \ud50c\ub77c\uc2a4\ud2f1 \uc18c\uc7ac \uacbd\ud5d8\uc740 \uc5d4\uc9c0\ub2c8\uc5b4\ub4e4\uc774 \uc18c\ud615 \ud2b9\uc9d5\uc774 \uc0dd\uc0b0\uc5d0 \ub4e4\uc5b4\uac00\uae30 \uc804\uc5d0 \ub808\uc9c4 \ud589\ub3d9, \ub3c4\uad6c \uc81c\uc57d \ubc0f \uac80\uc0ac \uacc4\ud68d\uc744 \ub9de\ucd94\ub3c4\ub85d \ub3d5\uc2b5\ub2c8\ub2e4.<\/div>\n<h2>What Are the Key Design Rules for Micro Molded Parts?<\/h2>\n<p>Designing for micro molding is not the same as scaling down a standard part design.

A 0.5 degree draft on a 5 mm deep feature seems negligible, but on a micro part with a 0.2 mm wall, that draft determines whether the part ejects cleanly or deforms. As discussed in our <a href=\"https:\/\/zetarmold.com\/ko\/%ec%82%ac%ec%b6%9c-%ea%b8%88%ed%98%95-%ec%99%84%eb%b2%bd-%ea%b0%80%ec%9d%b4%eb%93%9c\/\">injection mold guide<\/a>, we recommend a minimum of 1 degree draft on all vertical surfaces for micro parts, and 2 degrees for features deeper than 3 mm.<\/p>\n<p>Radii should be at least 0.05 mm on all internal corners. Sharp internal corners create stress concentrations that cause cracking during ejection or in service. At micro scale, even a 0.02 mm radius makes a measurable difference in part strength. Gate design is equally important \u2014 for parts under 0.5 g, a single edge gate with a maximum land length of 0.5 mm is usually the best choice.<\/p>\n<h2>How Is a Micro Injection Mold Different from a Standard Mold?<\/h2>\n<p>The fundamental difference is how the cavity is created.

The economics improve dramatically with volume because the fixed tooling cost amortizes quickly on a small, fast-cycle part.

Achieving this requires plunger-style injection systems with precision metering chambers accurate to 0.0001 cc and mold temperatures maintained above 100 degrees C throughout the entire injection cycle. At these extremely small dimensions, even a 0.0005 cc variation in shot volume produces a visible quality defect, so process control must be exceptionally tight and validated over thousands of consecutive cycles before full production release.<\/p>\n<h3>How much does a micro injection mold cost?<\/h3>\n<p>Micro mold tooling costs between $5,000 and $25,000 depending on part complexity, cavity count, and surface finish requirements. Single-cavity prototype molds for simple geometries start around $5,000, while multi-cavity production molds with tight tolerances and polished cavity surfaces run $15,000 to $25,000. The higher cost reflects the specialized EDM and wire cutting processes needed to create sub-millimeter cavity features that conventional CNC milling simply cannot achieve, regardless of the quality of the cutting tools or the skill of the machinist operating the equipment.<\/p>\n<h3>What tolerance can micro injection molding achieve?<\/h3>\n<p>Standard micro molding tolerances range from plus or minus 0.01 to 0.05 mm depending on the specific material being molded, the geometry of the part, and the aspect ratio of its critical features. Flat surfaces under 5 mm span in low-shrinkage materials like POM can consistently achieve plus or minus 0.008 mm in production. Deep holes with aspect ratios above 5:1 typically hold plus or minus 0.03 mm due to core pin deflection and uneven shrinkage around long steel features in the mold cavity.<\/p>\n<h3>What is the minimum wall thickness for micro injection molding?<\/h3>\n<p>Wall thicknesses down to 0.1 mm are achievable with low-viscosity materials like LCP, provided the mold is heated to 120 to 150 degrees C and injection speed exceeds 800 mm\/s to prevent premature freeze-off during cavity filling. Below 0.1 mm, cavity fill becomes extremely difficult because material solidifies on contact with the cavity wall almost instantly. Consistent wall variation under plus or minus 0.02 mm requires optimized gate placement within 2 mm of thin sections and rigorous process monitoring throughout the production run.<\/p>\n<h3>How long does a micro injection mold last?<\/h3>\n<p>Production micro molds typically last 200,000 to 500,000 cycles before cavity refurbishment, depending on the abrasiveness of the molding material and the feature complexity of the part design being produced. Molds running glass-filled or carbon-fiber reinforced materials may need rework at 100,000 cycles due to accelerated wear on fine cavity features. For ultra-tight tolerances, we strongly recommend re-measuring critical dimensions every 20,000 cycles and budgeting for cavity re-polishing or core replacement as routine preventive maintenance to avoid unexpected dimensional quality drift in production.<\/p>\n<h3>Can you micro mold PEEK?<\/h3>\n<p>Yes, PEEK micro molding is widely used for medical implants and aerospace applications requiring biocompatibility and continuous temperature resistance up to 250 degrees C. Processing requires barrel temperatures of 370 to 400 degrees C, mold temperatures of 160 to 200 degrees C, and injection speeds above 500 mm\/s. Barrel temperature control within plus or minus 2 degrees C is critical \u2014 a 5 degree C drift can cause 30 percent dimensional variation in a micro PEEK part, making precise thermal management essential for consistent production quality and dimensional repeatability.<\/p>\n<h3>What is the difference between micro molding and small part molding?<\/h3>\n<p>Micro molding specifically refers to parts under 1 gram with critical features below 1 mm, requiring dedicated plunger-injection machines with shot volumes of 0.001 to 5 cc and EDM-fabricated molds with sub-millimeter cavity details. Small part molding produces 1 to 10 gram parts on standard reciprocating-screw machines with conventional CNC-milled steel molds. These represent fundamentally different equipment categories, tooling approaches, and process control parameters, despite both processes ultimately producing relatively small plastic components for similar end-use applications across multiple industries.<\/p>\n<hr style=\"margin:2em 0;border:none;border-top:1px solid #e0e0e0;\" \/>\n<ol class=\"footnotes\">\n<li id=\"fn:1\">\n<p><strong>shot volumes:<\/strong> Shot volume is the amount of molten plastic injected into the mold cavity per cycle, measured in cubic centimeters.
