style="text-indent:25px">超聲波在生產(chǎn)中的運(yùn)用是非常較廣，像各類無紡布/化纖布的焊接、切割、分條，塑料類的焊接等，但是由于超聲波與高周波原理的差異，二者適用的原材料和運(yùn)用也會有區(qū)別。1、超聲波塑料焊接機(jī)是超聲波塑料焊接設(shè)備在塑料焊接領(lǐng)域研發(fā)設(shè)計(jì)的焊接設(shè)備，業(yè)內(nèi)稱之為超聲波塑焊機(jī)。超聲波焊接設(shè)備是熔接制品的高科技技術(shù)，在焊塑料制品時候，既不要添加任何粘接劑、填料或溶劑，也不會消耗大量熱源，具有操作簡便、焊接速度快、焊接強(qiáng)度高、生產(chǎn)穩(wěn)定、快等優(yōu)點(diǎn)。2、高周波是利用高頻電磁場使物料內(nèi)部分子間互相激烈碰撞產(chǎn)生高溫達(dá)到焊接和熔接的目的，而超聲波是利用超聲波換能器將電能轉(zhuǎn)化為熱能并通過加壓達(dá)到焊接和熔接的目的。高周波與超聲波的應(yīng)用領(lǐng)域都非常較廣。3、高周波類有高周波塑料熔接機(jī)、高周波皮塑熔斷機(jī)、高周波折盒壓痕機(jī)、高周波金屬熔鑄機(jī)、高周波金屬加熱機(jī)等。主要有：各種聚氯乙烯（PVC）為主的塑膠熔接、焊接、燙金等的高周波塑膠焊接機(jī)無錫塑料超聲波焊接設(shè)備廠家超聲波是指頻率超過20千赫茲的聲波。</p><div

style="text-indent:25px">超聲波對人體有什么危害？超聲波焊接有什么危害？超聲波焊接機(jī)使用的頻率一般有15khz，20khz，35khz，和40khz。這個頻率處于超聲波的較低頻段，遠(yuǎn)遠(yuǎn)低于醫(yī)用超聲檢測用的兆赫茲MHz級別，沒有確切的數(shù)據(jù)證明超聲波焊接機(jī)對人體有太大的傷害，但較少的缺點(diǎn)就是，焊接時一定要帶上耳塞，防止長時間工作，對聽力產(chǎn)生影響！對于工業(yè)用超聲，例如超聲波焊接，超聲波清洗，也是要結(jié)合超聲波頻率和聲強(qiáng)來看的，很多場合還要考慮暴露時間和強(qiáng)度，例如長時間處于超聲波清洗的相聲中，一句話來說，低頻超聲（20kHz左右），都需要有耳罩保護(hù)，雖然理論上無害，但聽著鬧心。</p><p style="text-indent:25px">超聲波焊接基本思想是在壓力下夾緊工件時將工件磨擦，以形成粘合。工件放置在鐵砧上，鐵砧上有細(xì)小的脊部，隆起的細(xì)脊被咬入材料中，在焊接過程中將其固定到位。然后將超聲波工具降低到工件上，在壓力下夾緊它們并產(chǎn)生所需的摩擦動作。對于大多數(shù)焊接操作，該工具以20千赫茲的頻率振動，對于低功率應(yīng)用，該工具以大約40千赫茲振動。該過程較初發(fā)現(xiàn)于1963年，當(dāng)時Sonics＆Materials Inc.的創(chuàng)始人Robert Soloff開始使用超聲探頭進(jìn)行實(shí)驗(yàn)。通過實(shí)驗(yàn)，Soloff發(fā)現(xiàn)聲波不受其他塑料焊接方式的限制。在此發(fā)現(xiàn)之后，Soloff繼續(xù)為Ideal Toy公司的工程師創(chuàng)建了靠前臺超聲波焊接機(jī)。超聲波焊接成為當(dāng)今使用的zui常用的塑料粘合方法之一。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">超聲波焊接機(jī)好常見的頻率為15khz和20khz超聲波塑料焊接機(jī)。超聲波頻率越高，焊接精度越好，但相對功率越小振幅也越小。下面介紹下超聲波塑料焊接機(jī)15khz跟20khz的區(qū)別：超聲波頻率低就會產(chǎn)生噪音，當(dāng)頻率低于20khz時，超聲波焊接時噪音變得很大。對焊接精度越高的塑料產(chǎn)品，頻率越高越好。因此20khz或者更高頻率的超聲波焊接機(jī)適合精密型、超薄型、非常脆弱的塑膠部件，例如SD卡、或者產(chǎn)品內(nèi)部有晶振的產(chǎn)品；15khz超聲波焊接機(jī)功率更容易做大，振幅也比較大，適合焊接較大型的，難易焊接的，比較粗獷的塑膠產(chǎn)品。壓力裝置用于固定焊接套件及施加焊接所需的作用力。深圳醫(yī)用超聲波焊接設(shè)備廠家推薦</p><p
