塑料焊接原理

超声波焊接塑料制品后，産品表面发白的原因

超聲波焊接是一種快速，高效的焊接方式，一切熱熔性塑料制品皆可應用。但是在焊接過程中，有時候超聲波塑料焊接處産品表面会发白，這到底是何種原因？這種發白的情況有以下幾種：外表面發白、熔接面發白、凸起處發白等。當出現這幾種情況的時候，我們應該如何進行處理？跟著靈科超聲波來了解一下：

1、外表面發白的情況。超聲波焊接塑料件時，如果塑件材質含玻纖，會出現焊接上表面發白。

解決方法：制作超聲波模具時，非焊接部位镂空。

2、熔接面發白。常出現在PC/ABS材質塑料件的焊接，超聲波焊接時壓力過大且焊接壁厚過薄，導致壁厚過壓折斷引起發白。

解決方法：減小焊接壓力，增加熔接時間。

3、凸起处发白。超声波塑料焊接时，发现局部有凸起且发白，观察産品内部结构，凸起处是否有定位柱（非焊接部位）。

解決方法：減短柱子高度。

‘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.
