Interessanterweise sind die meisten Hersteller unschl\u00fcssig, ob sie eine Haarschneidemaschine oder einen Trimmer herstellen sollen. Die beiden sehen zwar gleich aus, aber eine Schermaschine hat gr\u00f6\u00dfere Klingen und ist ideal zum Schneiden einer gro\u00dfen Menge Haare.<\/p>\n\n\n\n<p>Ein Haartrimmer hingegen ist darauf spezialisiert, das Haar sehr nah an der Haut zu schneiden. Sie haben feinere Klingen und sind leicht, was sie ideal f\u00fcr das Konturieren, Ausarbeiten, Einfassen und Stylen von Haaren macht. Die Hersteller von Haartrimmern stellen diese Produkte meist f\u00fcr die Reinigung von Dekollet\u00e9s, Koteletten oder die Pflege der Gesichtsbehaarung her. Zu den wichtigsten Merkmalen von Haartrimmern geh\u00f6ren:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Mehr Pr\u00e4zision und Details:<\/em><\/strong> Ausgestattet mit feineren Klingen, die scharfe, saubere Linien erm\u00f6glichen.<\/li>\n\n\n\n<li><strong><em>Tiefer schneiden:<\/em><\/strong> Sie schneiden k\u00fcrzer als Schermaschinen und sind damit die perfekte Wahl f\u00fcr Stoppeln, Details und saubere Fades.<\/li>\n\n\n\n<li><strong><em>Leichter als eine Schermaschine:<\/em><\/strong> Sie sind kompakter und leichter, so dass sie leichter zu handhaben sind und f\u00fcr komplizierte Details verwendet werden k\u00f6nnen.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-crucial-parts-of-a-hair-trimmer\">Wesentliche Teile eines Haartrimmers<\/h2>\n\n\n\n<p>F\u00fcr Existenzgr\u00fcnder, die in die Herstellung von Haartrimmern einsteigen wollen, ist es wichtig, die Bestandteile eines Haartrimmers zu kennen. Haartrimmer bestehen aus einem abnehmbaren Schneidsatz, der von einem Motor angetrieben wird. Die elektronischen Bauteile sind in einem Kunststoffgeh\u00e4use mit einem Netzschalter untergebracht. Nachstehend sind die wichtigsten Bestandteile eines Haartrimmers aufgef\u00fchrt.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Klingen:<\/em><\/strong> Dies ist der Teil, der das eigentliche Schneiden \u00fcbernimmt. Er besteht aus einer feststehenden Klinge, die wie ein Kamm wirkt, und einer beweglichen Klinge, die als Schneidevorrichtung dient. Die beweglichen Klingen vibrieren gegeneinander, um das Haar zu schneiden.<\/li>\n\n\n\n<li><strong><em>Motor:<\/em><\/strong> Sie liefert die Kraft, die die Bewegung der Fl\u00fcgel antreibt.<\/li>\n\n\n\n<li><strong><em>Geh\u00e4use:<\/em><\/strong> Das Geh\u00e4use ist die \u00e4u\u00dfere H\u00fclle, die die inneren Komponenten vor Sch\u00e4den durch St\u00f6\u00dfe und Umwelteinfl\u00fcsse sch\u00fctzt.<\/li>\n\n\n\n<li><strong><em>W\u00e4chter\/Grenzk\u00e4mme:<\/em><\/strong> Das sind aufsteckbare Kunststoffteile, die die L\u00e4nge der Haare bestimmen, die der Trimmer schneiden soll.

Nach Angaben des Kunden baute er eine Fabrik f\u00fcr die Massenproduktion von Haartrimmern auf und suchte ein Unternehmen, das ihn bei der Herstellung von Formen unterst\u00fctzen w\u00fcrde. Bei der Suche nach einem Werk f\u00fcr die Massenproduktion von Haartrimmern in China wurde First Mold h\u00e4ufig genannt.<\/p>\n\n\n\n<p>Bevor sie sich zu einem Gespr\u00e4ch \u00fcber ihr bevorstehendes Projekt zusammensetzten, baten sie um eine Besichtigung der Fabrik und der technologischen Einrichtung von First Mold. \u00dcberzeugt von dem, was sie sahen, entwarfen sie den Plan f\u00fcr ihr bevorstehendes Projekt. W\u00e4hrend sich die meisten Hersteller von Haartrimmern auf Produkte f\u00fcr Erwachsene konzentrieren, wollte dieser Kunde ein Produkt f\u00fcr Kinder entwickeln.<\/p>\n\n\n\n<p>Da dieser Kunde ein Neuling in der Branche war, wollte er auch Ratschl\u00e4ge bez\u00fcglich des besten Materials und des Spritzgussverfahrens f\u00fcr die Herstellung der verschiedenen Komponenten des Haartrimmers, insbesondere der Schutzvorrichtungen und des Geh\u00e4uses. Weitere wichtige Anforderungen an den Haartrimmer sind:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Wandst\u00e4rke:<\/em><\/strong> 1,0 mm oder weniger<\/li>\n\n\n\n<li><strong><em>Gesamtgewicht des Produkts:<\/em><\/strong> 200g bis 250g<\/li>\n\n\n\n<li><strong><em>Fehlertoleranz:<\/em><\/strong> Kein Grat und keine Grate<\/li>\n\n\n\n<li><strong><em>Oberfl\u00e4chenbehandlung:<\/em><\/strong> Seidendruck<\/li>\n\n\n\n<li><strong><em>Toleranz bei der Montage:<\/em><\/strong> \u00b10.0<em>5 mm<\/em><\/li>\n\n\n\n<li><strong><em>Ausbeute bei der Massenproduktion:<\/em><\/strong> \u226598%<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-challenges-and-solution\">Herausforderungen und L\u00f6sungen<\/h2>\n\n\n\n<p>Da der Hersteller eines Haartrimmers ein Produkt speziell f\u00fcr Kinder entwickelt hat, war es \u00e4u\u00dferst wichtig, dass die Schutzvorrichtungen und das Geh\u00e4use wegen der empfindlichen Kinderhaut keine Grate aufweisen. Der Grund daf\u00fcr ist, dass Grate winzige Schnitte auf der Haut von Kindern hinterlassen k\u00f6nnen. Au\u00dferdem wollte der Kunde ein leichtes Produkt herstellen. Daher war es f\u00fcr die Ingenieure von First Mold wichtig, ein leichtes Produkt zu entwickeln.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-material-compatibility-for-2k-molding\">Materialkompatibilit\u00e4t f\u00fcr 2K-Molding<\/h3>\n\n\n\n<p>Die zweite Herausforderung, die First Mold in Zusammenarbeit mit dem Hersteller des Haartrimmers bew\u00e4ltigen musste, war die Sicherstellung der Materialkompatibilit\u00e4t. Da es sich bei der Produktionstechnik um ein 2K-Spritzgussverfahren handelt, musste sichergestellt werden, dass die beiden Materialien, die f\u00fcr das Spritzgussverfahren verwendet werden, chemisch kompatibel sind, um eine gute Verbindung zu gew\u00e4hrleisten.<\/p>\n\n\n\n<p>Das erste Material muss der Temperatur des zweiten, hei\u00dferen Materials beim \u00dcberspritzen standhalten, ohne sich zu verformen oder zu schmelzen. Wenn sich die Materialien nicht richtig verbinden, kann sich der Soft-Touch-Griff w\u00e4hrend des Gebrauchs abl\u00f6sen. Auch wenn die <a href=\"https:\/\/firstmold.com\/de\/guides\/plastic-shrinkage\/\" type=\"post\" id=\"11677\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Schwindungsraten<\/strong><\/a> des harten und des weichen Materials erheblich voneinander abweichen, kann es zu Verformungen oder Rissen kommen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-intricate-hair-trimmer-mold-design\">Kompliziertes Haarschneideform-Design<\/h3>\n\n\n\n<p>Die <a href=\"https:\/\/firstmold.com\/de\/tag\/mold-design\/\" type=\"post_tag\" id=\"61\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Formenbau f\u00fcr das Two-Shot-Spritzgie\u00dfen<\/strong><\/a> erfordert in der Regel 30% bis 50% komplexere Werkzeuge. Zum Beispiel muss die Form so konstruiert sein, dass der erste Schuss zum \u00dcberspritzen in die zweite Kavit\u00e4t rotieren kann. Um eine gleichm\u00e4\u00dfige K\u00fchlung zu gew\u00e4hrleisten, musste eine Form mit gleichm\u00e4\u00dfiger Wandst\u00e4rke geschaffen werden.<\/p>\n\n\n\n<p>Um eine gleichm\u00e4\u00dfige K\u00fchlung zu erreichen, haben die Ingenieure von First Mold fortschrittliche K\u00fchlkan\u00e4le in der Form entwickelt. Dies ist auch f\u00fcr die Ma\u00dfhaltigkeit entscheidend. Die CAD-Simulation half den First Mold-Ingenieuren auch bei der Anschnittplatzierung, <a href=\"https:\/\/firstmold.com\/de\/guides\/mold-flow-analysis\/\" type=\"post\" id=\"11704\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Analyse des Formflusses<\/strong><\/a>, und finden Sie m\u00f6gliche Verformungen vor der Produktion.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/two-shot-mold-base-of-hair-trimmer.webp\" alt=\"Zwei-Schuss-Form Basis der Haarschneidemaschine\" class=\"wp-image-14409\" srcset=\"https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/two-shot-mold-base-of-hair-trimmer.webp 600w, https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/two-shot-mold-base-of-hair-trimmer-300x200.webp 300w, https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/two-shot-mold-base-of-hair-trimmer-18x12.webp 18w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption class=\"wp-element-caption\">Zwei-Schuss-Form Basis der Haarschneidemaschine<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-hair-trimmer-manufacturing-challenges-with-2k-molding\">Herausforderungen bei der Herstellung von Haartrimmern mit 2K-Molding<\/h3>\n\n\n\n<p>Das Two-Shot-Spritzgie\u00dfen erfordert in der Regel eine l\u00e4ngere Zykluszeit, da die zus\u00e4tzlichen Einspritzschritte, der Transfer und die K\u00fchlung in der Maschine erfolgen. Au\u00dferdem treten in der Regel h\u00e4ufiger Fehler auf, insbesondere in dem Bereich, in dem der zweite Schuss auf den ersten trifft. Dieser Fehler kann zu Abplatzungen, Rollneigung oder Sch\u00e4len f\u00fchren.<\/p>\n\n\n\n<p>Der erste Anschnitt kann Spuren hinterlassen. Die Ingenieure von First Mold stellten jedoch sicher, dass die Form sorgf\u00e4ltig so konstruiert wurde, dass der zweite Schuss alle Spuren des ersten Schusses \u00fcberdeckt. Durch diese konstruktive \u00dcberlegung entfielen auch kostspielige Nachbearbeitungen und Montageverz\u00f6gerungen, die den Hersteller Geld kosten w\u00fcrden.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-designing-hair-trimmer-housing-for-lightweight\">Design-Geh\u00e4use f\u00fcr Haartrimmer mit geringem Gewicht<\/h3>\n\n\n\n<p>Um das vom Hersteller des Haarschneiders vorgegebene Gewichtslimit einzuhalten, musste jedes Bauteil unter dem Gesichtspunkt der Leichtigkeit konstruiert werden. Statt dicker W\u00e4nde f\u00fcr das Geh\u00e4use entschieden sich die Ingenieure von First Mold beispielsweise f\u00fcr rippenverst\u00e4rkte d\u00fcnne W\u00e4nde.<\/p>\n\n\n\n<p>Um eine maximale Festigkeit zu gew\u00e4hrleisten, wurde die Rippengeometrie unter Verwendung von <a href=\"https:\/\/firstmold.com\/de\/tips\/nx-cad-vs-solidworks-vs-creo\/\" type=\"post\" id=\"23375\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>CAD-Software (SolidWorks)<\/strong><\/a>. Moldflow wurde zur Validierung des Designs f\u00fcr die Herstellbarkeit verwendet, um eine gleichm\u00e4\u00dfige Dicke zu gew\u00e4hrleisten und F\u00fcllprobleme zu vermeiden.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-preventing-flash-or-burrs-in-trimmer-guard\">Verhinderung von Gratbildung im Trimmerschutz<\/h3>\n\n\n\n<p>Es wurden mehrere Schritte unternommen, um die Bildung von Grat zu verhindern. Der erste war die Prozessoptimierung. Dazu geh\u00f6rte die Optimierung von Einspritzdruck und -geschwindigkeit. Ein zu hoher Druck kann das geschmolzene Material in die Trennebenen zwingen. Auch die Schmelztemperatur wurde optimiert, um die Viskosit\u00e4t bei zu fl\u00fcssigen Materialien zu erh\u00f6hen.<\/p>\n\n\n\n<p>Bei der Konstruktion der Form f\u00fcr das Haartrimmergeh\u00e4use erh\u00f6hten die Ingenieure von First Mold die Schlie\u00dfkraft, um die Form gegen den Innendruck des Kunststoffs fest geschlossen zu halten. Die Maschinenplatten waren parallel und richtig ausgerichtet, um einen ungleichm\u00e4\u00dfigen Schlie\u00dfdruck zu vermeiden.<\/p>\n\n\n\n<p>Durch die Kombination dieser Techniken wurde die Bildung von Blitzlicht vermieden und der Hersteller des Haarschneiders sparte wertvolle Ressourcen, die er f\u00fcr die Nachbearbeitung h\u00e4tte aufwenden m\u00fcssen. Au\u00dferdem wurde das Produkt dadurch f\u00fcr die Zielgruppe sicher.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-creating-tight-tolerance-for-easy-assembly\">Enge Toleranzen f\u00fcr eine einfache Montage<\/h3>\n\n\n\n<p>Angesichts der vom Hersteller geforderten engen Toleranzen (\u00b10,05 mm) mussten die Ingenieure von First Mold eine Kombination aus pr\u00e4ziser CAD-Konstruktion und CNC-Bearbeitung einsetzen, um die Formen f\u00fcr die Haartrimmer herzustellen. Enge Toleranzen sind entscheidend f\u00fcr die genaue Funktion der Komponenten. Eine geringf\u00fcgige Abweichung kann zu Montagefehlern, vorzeitigen Br\u00fcchen oder schwachen Verbindungen f\u00fchren.<\/p>\n\n\n\n<p>Eine enge Toleranz sorgt daf\u00fcr, dass der m\u00e4nnliche Haken und die weibliche Aussparung jedes Mal perfekt zueinander passen. Dadurch wird verhindert, dass der Schnappverschluss zu locker ist, was zu einem Klappern der Teile f\u00fchrt. Es wird auch verhindert, dass der Schnappverschluss zu fest ist, was zu einer \u00fcberm\u00e4\u00dfigen Montagekraft f\u00fchrt, die zu einer Besch\u00e4digung der Komponenten f\u00fchren k\u00f6nnte.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/Mold-core-part-of-the-main-part.webp\" alt=\"Formkernteil des Hauptteils\" class=\"wp-image-14407\" srcset=\"https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/Mold-core-part-of-the-main-part.webp 600w, https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/Mold-core-part-of-the-main-part-300x200.webp 300w, https:\/\/firstmold.com\/wp-content\/uploads\/2024\/02\/Mold-core-part-of-the-main-part-18x12.webp 18w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption class=\"wp-element-caption\">Formkernteil des Hauptteils<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-the-client-gained-by-embracing-first-mold-s-solutions\">Was der Kunde durch die \u00dcbernahme der L\u00f6sungen von First Mold gewonnen hat<\/h2>\n\n\n\n<p>Als der Kunde das Werk von First Mold betrat, war er sich \u00fcber den Unterschied zwischen einem Haarschneider und einem Trimmer nicht im Klaren.

Stattdessen wurden verschiedene Kunststoffmaterialien (ABS, PC, POM, PC+ABS und TPU) f\u00fcr verschiedene Komponenten vorgeschlagen, um die besten Ergebnisse zu erzielen.<\/p>\n\n\n\n<p>Obwohl die Herstellung von Zweikomponenten-Spritzgussteilen mehr technische F\u00e4higkeiten erfordert, konnte der Hersteller von Haartrimmern sein 2K-Werkzeug vor dem geplanten Beginn der Massenproduktion ausliefern. Die rechtzeitige Lieferung erm\u00f6glichte es dem Hersteller, Vorbestellungen zu erf\u00fcllen und das Nachfrageziel zu erreichen.<\/p>\n\n\n\n<p>Der Einsatz einer virtuellen Simulationssoftware erm\u00f6glichte es First Mold, die <a href=\"https:\/\/firstmold.com\/de\/guides\/what-is-mold-trial\/\" type=\"post\" id=\"19366\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Probeabformung<\/strong><\/a> Versuche auf maximal drei Versuche zu beschr\u00e4nken.
