服務器面板配件的表面處理技術要點

服務器面板配件的表面處理技術要點
在塑膠加工領域,服務器面板配件的表面處理至關重要,不僅影響產品的外觀質感,還關乎其功能性和耐用性。本文將深入探討服務器面板配件常用的表面處理技術及其要點。
一、噴涂工藝
(一)工藝流程

噴涂是通過噴槍等設備將涂料霧化并均勻地噴涂在塑膠表面。其基本流程包括:首先對服務器面板配件進行前處理,如清洗,去除表面的油污、灰塵和脫模劑等雜質,以確保涂料能夠良好附著。接著進行底漆噴涂,底漆能夠增強涂層與塑膠基體的附著力,同時提供一定的防腐保護。底漆噴涂后需經過烘干工序,使底漆充分固化。然后進行面漆噴涂,面漆決定了產品最終的顏色和光澤效果。最后再次烘干,使整個涂層完全固化。

(二)技術要點
  1. 涂料選擇:要根據服務器面板配件的使用環境和性能要求選擇合適的涂料。例如,在需要具備一定耐磨性的環境中,應選擇耐磨性好的涂料;若對耐候性有要求,則需選用耐候性佳的涂料。對于服務器面板,通常會選擇具有良好絕緣性能的涂料,以保障電子設備的安全運行。
  1. 噴涂環境:噴涂作業需要在潔凈的環境中進行,一般要求無塵車間,以防止灰塵顆粒混入涂層,影響表面質量。同時,環境的溫度和濕度也需嚴格控制,溫度一般保持在 20℃-25℃,濕度控制在 40%-60%,這樣的環境條件有助于涂料的均勻噴涂和良好固化。世邦注塑模具廠 目前的噴涂、絲印、組裝車間均是10萬級無塵車間,滿足生產需求。
二、電鍍工藝
(一)工藝流程

塑膠電鍍并非對所有塑膠材質都適用,對于服務器面板配件常用的塑膠材料,如 ABS,電鍍流程較為復雜。首先是去除塑膠表面的油污,確保后續處理的有效性。然后進行粗化處理,增加鍍層與基體的接觸面積,提高附著力。之后進行電鍍,將經過預處理的塑膠件放入電鍍液中,通過電解作用使金屬離子在塑膠表面沉積形成鍍層。最后進行后處理,如鈍化處理,提高鍍層的耐腐蝕性。

(二)技術要點
  1. 材質適用性:如前文所述,并非所有塑膠都適合電鍍,ABS 是塑膠電鍍中常用的材質。在選擇塑膠原料時,要確保其質量穩定,雜質含量低,以保證電鍍效果。不同批次的 ABS 材料可能在成分和性能上存在差異,這可能會影響電鍍的附著力和鍍層質量,因此要嚴格把控原料質量。
  1. 設計注意事項:在設計服務器面板配件時,要考慮電鍍工藝的特點。避免出現壁厚不均勻的情況,因為金屬光澤會凸顯縮癟現象,影響外觀。同時,要盡量減少盲孔、凹槽和突出部位,盲孔內的處理液難以清洗干凈,會影響電鍍質量;凹槽和突出部位在電鍍時易出現露塑或鍍焦問題。此外,鍍件應設計足夠的裝掛位置,與掛具的接觸面要適當增大,以確保電鍍過程中的電流傳導均勻。

三、絲印工藝
(一)工藝流程

絲印是通過絲網版將油墨轉移到塑膠表面形成圖案或文字。其流程為:首先制作絲網版,根據設計要求將需要印刷的圖案或文字通過感光制版等方法制作在絲網上,使圖案部分的絲網成為通透的網孔。然后將絲網版固定在絲印機上,將服務器面板配件放置在合適的位置。接著在絲網版上倒入油墨,通過刮刀的擠壓使油墨透過網孔,轉移到塑膠表面,形成所需的圖案或文字。印刷完成后,進行油墨固化處理,可通過自然干燥、加熱烘干或紫外線照射固化等方式,使油墨牢固附著在塑膠表面。

(二)技術要點
  1. 絲網版制作:絲網版的質量直接影響絲印效果。絲網的材質、目數以及圖案制作的精度都很重要。對于服務器面板配件上精細的圖案或文字印刷,應選擇目數較高的絲網,如 300-400 目,以保證圖案的清晰度。在制作絲網版時,要確保圖案的邊緣清晰、光滑,避免出現鋸齒狀或模糊不清的情況,否則會影響印刷質量。
  1. 油墨選擇:根據塑膠材料的特性和印刷產品的使用環境選擇合適的油墨。例如,對于需要在戶外使用的服務器面板配件,應選擇耐候性好的油墨,以防止圖案褪色。同時,油墨的附著力也至關重要,要確保油墨能夠牢固地附著在塑膠表面,不易脫落。對于一些特殊的塑膠材料,可能需要對油墨進行特殊調配或添加附著力促進劑。
  1. 印刷參數調整:刮刀的硬度、刮印角度和刮印壓力等參數需要根據絲網版的材質、油墨的特性以及印刷圖案的要求進行調整。刮刀硬度適中,太軟無法將油墨充分擠壓透過網孔,太硬則可能損壞絲網版。刮印角度一般在 60°-80° 之間,刮印壓力要均勻,壓力過小油墨轉移不充分,壓力過大可能導致油墨滲出,影響圖案的精度。
