超聲波焊接原理

簡述超聲波熔接“經濟效益”（二）

前文靈科有提到超聲波熔接作業時是要注意超聲波HORN的原始設計的。

所谓超声波HORN的原始设计，是信息层面的，这信息层面就是産品的塑料熔点、熔接功能需求（是否一般熔接、水、气密、熔接强度、拉拔力等），一般如15kHz×2200W的超聲波熔接機，在15000次/秒振動摩擦生熱的頻率+2200W推動位移的功率，在30ψ單位面積裏，約産生115℃的熱能，而欲熔接ABS（熔點約120℃）的塑材，則超聲波HORN的能量擴大比率，在經驗值中應以擴大1.5倍（115℃×1.5倍=172℃）爲適合，若爲PC（熔點約270℃）的塑材，則超聲波HORN的能量擴大比率，在經驗值中應以擴大2.5倍（115℃×2.5倍=288℃）爲適合。

當然這些理論與實務，所産生的經驗值，對一般非超聲波專業制造者，可能會較爲深入，但在超聲波熔接检测方面，则可以从电子控制箱的振幅表观察出来，亦即超声波作用在産品上时，在0.4秒的熔接时间内，如果产生有2.5um的振幅时，即可熔接一般ABS材料，如果产生有3.5um的振幅时，则可熔接PC材料，这也就是说明在超声波的振动频率，与推动功率作用于塑料産品时，可以在0.4秒的瞬间内，达到熔点，当然亦有比较特殊的熔接模式，如材料韧性较高的如PP、PE、耐隆等，则不仅需要瞬间可达于熔点的超声波扩大振幅，还必需使用低压力，配合机器上的定位微调，再以超声波传导的方式，来达到熔合的需求。

終歸而言，超聲波熔接的“效率”与“收益”，是建立在信息、制造技术、生产技巧的整合，不能偏执于单方面的取舍、如此才是符合超聲波熔接作业的整合型经济效益。灵科公司拥有70多台CNC加工设备，为客户供应中山超声波焊接机、江门超声波塑焊机、阳江超音波设备配件等、根据厂家需求定制非标设备。

超聲波熔接産品总是单边烫伤的处理方法

简述超聲波熔接“经济效益”（一）

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
