    Define fixture, orientation, temperature, conditioning time, filter settings and data reduction. Without a common method, two laboratories can report different values for the same part. Measurement-system analysis should precede arguments about small process differences.<\/p>\n

    Capability Data Must Stay Cavity-Specific<\/h2>\n

    \"cavity-separated-optical-part-sample-trays\"<\/p>\n

    A combined capability number can hide one poor cavity behind several good ones. Track cavities separately during tool qualification and after maintenance. Also review trends over time; a centered short trial does not prove long-run stability.<\/p>\n

    In \uad11\ud559 \ubc0f \ud22c\uba85 \uc0ac\ucd9c \uc131\ud615<\/a>, dimensional capability should be connected to optical output. If a dimension remains capable while functional performance drifts, the control plan is missing a contributor such as stress, surface condition or assembly load.<\/p>\n

    Do not confuse resolution with measurement confidence<\/h3>\n

    An instrument displaying additional decimal places is not automatically capable of accepting a tight tolerance. Fixture repeatability, edge detection, temperature, operator setup and data filtering all contribute uncertainty. Run repeatability and reproducibility work on representative transparent parts, because clear edges can behave differently from calibration artifacts.<\/p>\n

    Freeze the acceptance method with the drawing<\/h3>\n

    State whether surface form is evaluated over the full aperture or after removing tilt and power, whether the part is free or constrained, and how outliers are treated. If buyer and supplier use different filters or fixtures, both can follow the drawing and still disagree. A shared method and correlated samples should be approved before production tooling is released.<\/p>\n

    Review tolerance changes as system changes<\/h3>\n

    Tightening one molded dimension can shift cost into tool correction, cycle time, inspection and yield without improving the assembly. Before revising a limit, rerun the optical sensitivity and stack analysis. Sometimes a locating feature, compliant mount or calibration step controls output more effectively than a tighter lens dimension.<\/p>\n

    For procurement, request the proposed measurement method and capability by cavity rather than a generic promise of \u201chigh precision.\u201d Ask which dimensions are controlled in the mold, which require process compensation, and which optical characteristics are verified functionally. This creates comparable quotations and exposes assumptions early.<\/p>\n

    Can standard molded-part tolerances be used for lenses?<\/h3>\n

    They can guide nonoptical features, but optical surfaces and axis relationships need function-specific limits and measurement methods.<\/p>\n

    Should the CAD nominal equal the tool surface?<\/h3>\n

    Not necessarily. Predictable molding shrinkage and form change may require compensated steel after stable trial data is available.<\/p>\n

    How should suppliers quote a tight optical tolerance?<\/h3>\n

    They need the drawing, optical function, material grade, measurement definition, sample plan, assembly condition and acceptance data\u2014not the tolerance value alone.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

    Tight dimensions can still fail optically because optical injection molding tolerances must control relationships, not isolated numbers. A lens can meet diameter, thickness and flatness limits while its optical axis is decentered from the mounting datum. A clear window can pass a profile check and still distort an image through local form error or molding […]<\/p>\n","protected":false},"author":1,"featured_media":3786,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3729","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts\/3729","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/comments?post=3729"}],"version-history":[{"count":0,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts\/3729\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/media\/3786"}],"wp:attachment":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/media?parent=3729"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/categories?post=3729"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/tags?post=3729"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
