超聲波焊接原理

“超聲波焊接”的密封應用

超聲波密封时，仅会在热塑性密封层内造成熔融需要的热量。将振动部分转换为摩擦能源，底砧和超声波模具焊头上大多数为径向的或含有小平台样子的线形轮廓。这类轮廓可以将能量导进聚焦起來，使密封時间减短，仅为100ms至200ms。超聲波密封时，薄膜內部造成发热量，而不是如热密封时由外界导进发热量。与包装制品直接接触的模具、超声波焊头和底砧，在焊接全过程中维持常温。支撑点层也基本上维持在常温下，在能量键入完毕后，因为支撑点层和密封层中间存有温度差，能源也可以顺利地向外传输出来 - 焊缝的抗压强度显著高些。

必须将引进的震动能量聚焦，才可以操纵焊接物件的融化情况。薄膜和别的塑料软包装原材料的焊接中的聚焦主要是根据适度的专用工具设计方案完成的。减少添充高宽比以保护商品，降到最低薄膜钢筋搭接以节约原材料，根据超音波纵向密封的同时，冲切标准挂袋孔，焊缝地区中有産品剩下时也可以开展密封。不论是热填充料或是无菌检测袋和蒸煮袋，超声波焊接技术性都能使焊缝密封填充，自然环境尽管充斥着尘土，但根据超声波模具的震动仍能做到靠谱的焊缝品质，根据应用常温下密封工具减少废料总数和对産品开展维护。

超聲波密封尤其適用于：

袋子的熱塑性塑料薄膜

內膽、外罩和杯子

帶有熱塑性塗層的紙盒

閥門的薄膜/過濾材料

紙盒/薄膜上的螺旋蓋

“超聲波”模具設計與制造的基本原理

‘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.
