O silicone n\u00e3o \u00e9 borracha, e um\u00a0molde de silicone<\/strong>\u00a0n\u00e3o \u00e9 um molde de borracha. A borracha de silicone l\u00edquida (LSR) possui propriedades de fluidez, processo qu\u00edmico de cura e caracter\u00edsticas de desmoldagem \u00fanicas, que exigem ferramentas especializadas. Em\u00a0PartsMastery<\/strong>, A nossa empresa concebe e fabrica produtos de precis\u00e3o\u00a0molde de silicone<\/strong>\u00a0ferramentas para moldagem por compress\u00e3o, moldagem por inje\u00e7\u00e3o e componentes de silicone moldados por fundi\u00e7\u00e3o, para aplica\u00e7\u00f5es nas \u00e1reas m\u00e9dica, autom\u00f3vel, de bens de consumo e industrial.<\/p>\n

Este guia completo explica o que \u00e9 um\u00a0molde de silicone<\/strong>\u00a0ou seja, em que difere dos moldes de borracha convencionais, os princ\u00edpios-chave de conce\u00e7\u00e3o e como selecionar o material e a geometria adequados para a sua aplica\u00e7\u00e3o.<\/p>\n

1. O que \u00e9 um molde de silicone?<\/h3>\n

A\u00a0molde de silicone<\/strong>\u00a0\u00e9 uma ferramenta utilizada para moldar borracha de silicone l\u00edquida ou s\u00f3lida, transformando-a em pe\u00e7as elastom\u00e9ricas acabadas atrav\u00e9s do calor e da press\u00e3o. Ao contr\u00e1rio dos compostos de borracha org\u00e2nica que curam com enxofre, o silicone cura atrav\u00e9s de um catalisador de platina ou de per\u00f3xido. A\u00a0molde de silicone<\/strong>\u00a0tem de resistir aos desafios espec\u00edficos do LSR: viscosidade extremamente baixa (semelhante \u00e0 da \u00e1gua), tempos de cura r\u00e1pidos (segundos a minutos) e ades\u00e3o agressiva \u00e0s superf\u00edcies de a\u00e7o.<\/p>\n

A moldagem por inje\u00e7\u00e3o de LSR \u00e9 a mais comum\u00a0molde de silicone<\/strong>\u00a0aplica\u00e7\u00e3o. Dois componentes l\u00edquidos \u2014 a Parte A (base) e a Parte B (catalisador) \u2014 s\u00e3o misturados num misturador est\u00e1tico imediatamente antes de entrarem no\u00a0molde de silicone<\/strong>. O material flui facilmente at\u00e9 para as cavidades mais pequenas, solidifica a 150-200 \u00b0C e s\u00f3 se solta se o\u00a0molde de silicone<\/strong>\u00a0A superf\u00edcie est\u00e1 perfeitamente preparada. Um projeto mal concebido\u00a0molde de silicone<\/strong>\u00a0vai aderir de forma permanente \u00e0 pe\u00e7a.<\/p>\n

2. Tipos de processos de moldagem de silicone<\/h3>\n

A conce\u00e7\u00e3o do seu\u00a0molde de silicone<\/strong>\u00a0depende em grande medida do processo que estiver a utilizar:<\/p>\n

Moldagem por inje\u00e7\u00e3o de borracha de silicone l\u00edquida (LSR):<\/strong>
\nO mais avan\u00e7ado\u00a0molde de silicone<\/strong>\u00a0configura\u00e7\u00e3o. O silicone l\u00edquido de duas componentes \u00e9 dosado, misturado e injetado diretamente num molde fechado e aquecido\u00a0molde de silicone<\/strong>. Os tempos de cura variam entre 15 e 90 segundos. Inje\u00e7\u00e3o de LSR\u00a0molde de silicone<\/strong>\u00a0Estas ferramentas incluem canais frios (para evitar a cura prematura) e cavidades quentes (para acelerar a cura). Aplica\u00e7\u00f5es t\u00edpicas: m\u00e1scaras m\u00e9dicas, tetinas para biber\u00f5es, teclados.<\/p>\n

Moldagem por compress\u00e3o de borracha de alta consist\u00eancia (HCR):<\/strong>
\nA\u00a0molde de silicone<\/strong>\u00a0para silicone s\u00f3lido, com consist\u00eancia de massa de modelar. Uma pe\u00e7a em bruto previamente pesada \u00e9 colocada na abertura\u00a0molde de silicone<\/strong>\u00a0cavidade. O calor e a press\u00e3o provocam a cura do material. HCR\u00a0molde de silicone<\/strong>\u00a0As ferramentas s\u00e3o mais simples e mais baratas do que as ferramentas LSR. Aplica\u00e7\u00f5es t\u00edpicas: tapetes de cozinha, luvas de forno, juntas industriais.<\/p>\n

Moldagem de silicone fundido (vulcaniza\u00e7\u00e3o \u00e0 temperatura ambiente):<\/strong>
\nA\u00a0molde de silicone<\/strong>\u00a0utilizado \u00e0 temperatura ambiente ou em lume brando. O silicone l\u00edquido \u00e9 vertido ou injetado num\u00a0molde de silicone<\/strong>\u00a0(geralmente fabricado a partir de um molde-mestre num material diferente) e endurece sem press\u00e3o externa. Aplica\u00e7\u00f5es t\u00edpicas: prot\u00f3tipos, reprodu\u00e7\u00f5es art\u00edsticas, almofadas para dispositivos m\u00e9dicos.<\/p>\n

4. Materiais utilizados nos moldes de silicone<\/h3>\n

O\u00a0molde de silicone<\/strong>\u00a0tem de resistir ao ataque qu\u00edmico dos catalisadores de platina e libertar-se facilmente:<\/p>\n

A\u00e7o para ferramentas H-13 (46-52 HRC):<\/strong>
\nO preferido\u00a0molde de silicone<\/strong>\u00a0material para moldagem por inje\u00e7\u00e3o de LSR em grande volume. O H-13 resiste \u00e0 forma\u00e7\u00e3o de fissuras por calor e mant\u00e9m um polimento perfeito durante mais tempo do que qualquer outro a\u00e7o. A\u00a0molde de silicone<\/strong>\u00a0Fabricadas a partir de H-13, podem produzir milh\u00f5es de pe\u00e7as.<\/p>\n

A\u00e7o inoxid\u00e1vel (420, 17-4 PH):<\/strong>
\nPara\u00a0molde de silicone<\/strong>\u00a0aplica\u00e7\u00f5es que envolvam silicones para uso m\u00e9dico ou em contacto com alimentos. O a\u00e7o inoxid\u00e1vel evita a corros\u00e3o causada pelos catalisadores de platina e cumpre os requisitos da FDA para salas limpas.<\/p>\n

A\u00e7o para ferramentas P-20 (30-36 HRC):<\/strong>
\nPara volumes mais reduzidos\u00a0molde de silicone<\/strong>\u00a0aplica\u00e7\u00f5es (menos de 250 000 ciclos). O P-20 \u00e9 mais barato do que o H-13, mas apresentar\u00e1 desgaste e degrada\u00e7\u00e3o da superf\u00edcie mais cedo.<\/p>\n

Alum\u00ednio (7075-T6):<\/strong>
\nPara prot\u00f3tipo\u00a0molde de silicone<\/strong>\u00a0ferramentas ou produ\u00e7\u00e3o em pequenas s\u00e9ries (menos de 10 000 pe\u00e7as). Alum\u00ednio\u00a0molde de silicone<\/strong>\u00a0Estas ferramentas aquecem e arrefecem rapidamente, mas requerem um revestimento resistente para impedir a ader\u00eancia do silicone.<\/p>\n

5. Elementos cr\u00edticos de conce\u00e7\u00e3o de um molde de silicone<\/h3>\n

Um \u00eaxito\u00a0molde de silicone<\/strong>\u00a0inclui v\u00e1rias funcionalidades exclusivas do LSR:<\/p>\n

Sistema de canais frios:<\/strong>
\nAo contr\u00e1rio dos moldes termopl\u00e1sticos, em que os canais de alimenta\u00e7\u00e3o est\u00e3o quentes, um LSR\u00a0molde de silicone<\/strong>\u00a0utiliza um canal frio (5-25 \u00b0C) para evitar a cura prematura no sistema de alimenta\u00e7\u00e3o. O\u00a0molde de silicone<\/strong>\u00a0O canal frio est\u00e1 isolado termicamente da placa da cavidade quente. A \u00e1gua refrigerada circula continuamente pela placa do canal.<\/p>\n

V\u00e1lvulas de corte e conce\u00e7\u00e3o das comportas:<\/strong>
\nComo o LSR flui como a \u00e1gua, um\u00a0molde de silicone<\/strong>\u00a0Exige fechos herm\u00e9ticos (folga de 0,005-0,010 mm) para evitar excesso de material. As entradas pontuais (di\u00e2metro de 0,3-0,8 mm) s\u00e3o padr\u00e3o. As entradas submersas funcionam bem, mas exigem precis\u00e3o\u00a0molde de silicone<\/strong>\u00a0maquina\u00e7\u00e3o.<\/p>\n

Ventila\u00e7\u00e3o:<\/strong>
\nO LSR liberta gases durante a cura (metanol, hidrog\u00e9nio). A\u00a0molde de silicone<\/strong>\u00a0requer aberturas de ventila\u00e7\u00e3o mais profundas do que os moldes de borracha \u2014 normalmente com 0,05 a 0,10 mm de profundidade. As aberturas de ventila\u00e7\u00e3o devem ser posicionadas no \u00faltimo ponto de enchimento do\u00a0molde de silicone<\/strong>\u00a0cavidade.<\/p>\n

Acabamento da superf\u00edcie:<\/strong>
\nA\u00a0molde de silicone<\/strong>\u00a0deve ter uma superf\u00edcie perfeitamente polida (SPI A-2 ou superior). Qualquer arranh\u00e3o ou defeito na\u00a0molde de silicone<\/strong>\u00a0poder\u00e1 transferir-se para a pe\u00e7a e causar ader\u00eancia. Os acabamentos espelhados (SPI A-1) s\u00e3o comuns em pe\u00e7as de silicone \u00f3tico.<\/p>\n

\u00c2ngulos de projeto:<\/strong>
\nApesar da flexibilidade do LSR, um\u00a0molde de silicone<\/strong>\u00a0requer \u00e2ngulos de desmoldagem de 1 a 3 graus \u2014 inferiores aos dos moldes de borracha, uma vez que o LSR se desmolda mais facilmente quando devidamente polido.<\/p>\n

Pinos ejetores:<\/strong>
\nA\u00a0molde de silicone<\/strong>\u00a0utiliza menos pinos ejetores do que um molde de borracha, uma vez que as pe\u00e7as de LSR s\u00e3o frequentemente suficientemente flex\u00edveis para se soltarem. No entanto, os pinos ejetores num\u00a0molde de silicone<\/strong>\u00a0tem de ficar perfeitamente nivelado com a superf\u00edcie da cavidade \u2014 qualquer desn\u00edvel na altura provocar\u00e1 rebarbas.<\/p>\n

6. O processo de fabrico de moldes de silicone<\/h3>\n

Construir uma precis\u00e3o\u00a0molde de silicone<\/strong>\u00a0exige uma aten\u00e7\u00e3o extrema ao acabamento da superf\u00edcie:<\/p>\n

1. Compensa\u00e7\u00e3o do encolhimento:<\/strong>
\nO silicone encolhe entre 2,0 e 4,01 TP3T, dependendo da formula\u00e7\u00e3o. Moldamos placas de teste com o seu tipo espec\u00edfico de LSR e medimos o encolhimento em todos os eixos antes da fase final\u00a0molde de silicone<\/strong>\u00a0maquina\u00e7\u00e3o.<\/p>\n

2. Maquina\u00e7\u00e3o CNC:<\/strong>
\nO\u00a0molde de silicone<\/strong>\u00a0As metades s\u00e3o cortadas de forma grosseira em a\u00e7o H-13 ou a\u00e7o inoxid\u00e1vel e, em seguida, submetidas a um acabamento mec\u00e2nico utilizando um CNC de 5 eixos. Deixamos 0,05 mm de material em excesso para o polimento final.<\/p>\n

3. Tratamento t\u00e9rmico:<\/strong>
\nO\u00a0molde de silicone<\/strong>\u00a0\u00e9 temperado (H-13 a 48-52 HRC) e, em seguida, submetido a um duplo revenimento para aliviar as tens\u00f5es. Um material com tens\u00f5es aliviadas\u00a0molde de silicone<\/strong>\u00a0resiste \u00e0 fadiga t\u00e9rmica ao longo de milh\u00f5es de ciclos.<\/p>\n

4. Polimento com diamante:<\/strong>
\nTodas as superf\u00edcies da cavidade do\u00a0molde de silicone<\/strong>\u00a0\u00e9 polido \u00e0 m\u00e3o com compostos de diamante. O acabamento final da superf\u00edcie \u00e9 de 0,05 microns Ra ou melhor \u2014 um verdadeiro espelho. Este processo demora entre 20 e 40 horas para um exemplar t\u00edpico\u00a0molde de silicone<\/strong>.<\/p>\n

5. Maquina\u00e7\u00e3o a frio de canais de inje\u00e7\u00e3o:<\/strong>
\nA placa do canal frio do\u00a0molde de silicone<\/strong>\u00a0\u00e9 usinado a partir de um bloco separado de a\u00e7o ou alum\u00ednio. As barreiras t\u00e9rmicas (espa\u00e7os de ar ou isoladores de PEEK) separam o canal frio da placa da cavidade quente.<\/p>\n

6. Revestimento (facultativo):<\/strong>
\nNo caso dos silicones dif\u00edceis de desmoldar, o\u00a0molde de silicone<\/strong>\u00a0A cavidade pode receber um revestimento \u00e0 base de PTFE ou DLC (carbono tipo diamante). Isto reduz a ader\u00eancia, mas requer uma nova aplica\u00e7\u00e3o a cada 100 000-200 000 ciclos.<\/p>\n
