電梯門套作為電梯出入口的裝飾與防護結構，其制作需兼顧美觀性與實用性，在濰坊地區的制作過程中，通常遵循材料篩選、加工成型、表面處理、適配安裝四個核心步驟，每個環節的精細操作直接影響最終成品的品質。

　　As a decorative and protective structure for elevator entrances and exits, the production of elevator door frames needs to balance aesthetics and practicality. In the production process in Weifang area, four core steps are usually followed: material screening, processing and shaping, surface treatment, and adaptation and installation. The fine operation of each link directly affects the quality of the final product.

　　一、材料篩選與預處理

　　1、 Material screening and pretreatment

　　根據電梯使用場景（如住宅、商場、醫院）的不同，選擇適配的基礎材料。常見材料包括木質復合板、石塑板、不銹鋼板等：木質復合板適合溫馨風格的住宅電梯，需選用含水率低于 12% 的防潮板材，避免后期變形；石塑板具有耐磨、防火特性，多用于人流量大的商場；不銹鋼板則以其耐腐蝕、易清潔的特點，成為醫院等場所的優選。

　　Choose suitable basic materials based on the different usage scenarios of elevators, such as residential areas, shopping malls, and hospitals. Common materials include wooden composite panels, stone plastic panels, stainless steel panels, etc. Wooden composite panels are suitable for warm style residential elevators, and moisture-proof panels with a moisture content of less than 12% should be selected to avoid deformation in the later stage; Stone plastic board has wear-resistant and fire-resistant properties, and is often used in shopping malls with high foot traffic; Stainless steel plates have become the preferred choice for hospitals and other places due to their corrosion resistance and ease of cleaning.

　　材料進場后需進行預處理：板材需在通風環境中靜置 48 小時以上，使其適應濰坊地區的溫濕度（年均濕度 60%-70%），減少后期收縮或膨脹。對于不銹鋼板，需用專用清潔劑去除表面油污與氧化層；石塑板則需檢查表面平整度，對輕微劃痕用細砂紙打磨修復，確保基材無缺陷。

　　Pre treatment is required after the materials enter the site: the boards need to be left in a ventilated environment for more than 48 hours to adapt to the temperature and humidity of Weifang area (average annual humidity of 60% -70%), reducing later shrinkage or expansion. For stainless steel plates, specialized cleaning agents are required to remove surface oil stains and oxide layers; The surface flatness of the stone plastic board needs to be checked, and minor scratches should be polished and repaired with fine sandpaper to ensure that the substrate is defect free.

　　二、精準加工與結構成型

　　2、 Precision machining and structural forming

　　首先依據電梯門洞的實際尺寸（寬度、高度、墻體厚度）進行 CAD 圖紙設計，確定門套的邊框、橫頭、線條等部件的規格，預留 2-3mm 的安裝間隙。切割環節采用數控切割設備，木質復合板與石塑板需使用專用鋸片，避免邊緣崩裂；不銹鋼板則采用等離子切割，確保切口光滑無毛刺。

　　Firstly, based on the actual dimensions of the elevator door opening (width, height, wall thickness), CAD drawings are designed to determine the specifications of the frame, horizontal head, lines, and other components of the door frame, with a reserved installation gap of 2-3mm. The cutting process uses CNC cutting equipment, and specialized saw blades are required for wooden composite boards and stone plastic boards to avoid edge cracking; Stainless steel plates are cut using plasma cutting to ensure a smooth and burr free cut.

　　折彎成型是關鍵步驟，對于需要弧度的門套線條（如圓角設計），不銹鋼板通過數控折彎機按預設角度（通常為 90° 或 135°）折彎，折彎處需預留 0.5mm 的緩沖空間；石塑板則通過加熱軟化后定型，冷卻后進行邊緣修整。拼接部位需加工榫卯結構或預留卡扣槽，確保組裝時接縫嚴密，縫隙控制在 0.3mm 以內。

　　Bending forming is a key step. For door frame lines that require curvature (such as rounded corner design), stainless steel plates are bent at a preset angle (usually 90 ° or 135 °) using a CNC bending machine, with a 0.5mm buffer space reserved at the bend; The stone plastic board is shaped by heating and softening, and then edge trimming is carried out after cooling. The splicing parts need to be processed with mortise and tenon structures or reserved buckle slots to ensure tight joints during assembly, with gaps controlled within 0.3mm.

　　三、表面處理與裝飾加工

　　3、 Surface treatment and decorative processing

　　根據設計風格進行表面處理：木質復合板需進行底漆涂刷，選用環保型水性底漆，均勻噴涂 2-3 遍，每遍間隔 4 小時以上，待干燥后用 400 目砂紙輕磨，去除表面顆粒；石塑板可通過熱轉印技術附著木紋、石紋等圖案，轉印溫度控制在 180-200℃，壓力保持 0.3MPa，確保圖案清晰且附著力強。

　　Surface treatment according to design style: Wooden composite panels need to be coated with environmentally friendly water-based primer, evenly sprayed 2-3 times, with an interval of more than 4 hours between each coat. After drying, use 400 grit sandpaper to lightly grind and remove surface particles; Stone plastic board can be attached with wood grain, stone grain and other patterns through heat transfer printing technology. The transfer printing temperature is controlled at 180-200 ℃, and the pressure is maintained at 0.3MPa to ensure clear patterns and strong adhesion.

　　不銹鋼板的表面處理則分為拉絲、鏡面、噴涂三種：拉絲處理通過砂帶研磨形成均勻紋理，方向需與板材長度一致；鏡面處理需經過多道拋光工序，使表面光澤度達到 8K 以上；噴涂處理需先進行磷化處理增強附著力，再噴涂氟碳漆，固化溫度控制在 120℃左右，確保涂層耐候性符合濰坊地區的氣候要求。

　　The surface treatment of stainless steel plates can be divided into three types: wire drawing, mirror finish, and spray coating. Wire drawing treatment forms a uniform texture through sanding with a sand belt, and the direction needs to be consistent with the length of the plate; Mirror treatment requires multiple polishing processes to achieve a surface glossiness of over 8K; Spraying treatment requires phosphating treatment to enhance adhesion, followed by spraying fluorocarbon paint. The curing temperature should be controlled at around 120 ℃ to ensure that the weather resistance of the coating meets the climate requirements of Weifang area.

　　四、適配調整與安裝準備

　　4、 Adaptation adjustment and installation preparation

　　完成加工的門套部件需在出廠前進行預組裝測試，模擬電梯門洞尺寸搭建測試框架，將邊框、橫頭拼接后，檢查對角線誤差是否在 1mm 以內，垂直度偏差不超過 0.5mm/m。對于存在輕微偏差的部位，用專用打磨工具進行微調，確保整體結構方正。

　　The processed door frame components need to undergo pre assembly testing before leaving the factory, simulating the size of elevator door openings to build a testing framework. After splicing the frame and horizontal head, check whether the diagonal error is within 1mm and the vertical deviation does not exceed 0.5mm/m. For areas with slight deviations, use specialized polishing tools to fine tune and ensure that the overall structure is square.

　　安裝前的準備工作包括：根據墻體材質（磚墻、混凝土墻、輕鋼龍骨墻）準備適配的固定件，如膨脹螺絲、卡扣、膠粘劑等；對門套背面進行防潮處理，木質與石塑材質需涂刷防潮涂料，不銹鋼材質則粘貼隔音棉，減少電梯運行時的噪音傳導。最后進行編號打包，按安裝順序標注部件位置，便于現場快速組裝。

　　The preparation work before installation includes: preparing suitable fasteners such as expansion screws, buckles, adhesives, etc. according to the wall material (brick wall, concrete wall, light steel keel wall); Moisture proof treatment should be applied to the back of the door frame. Wooden and stone plastic materials should be coated with moisture-proof paint, while stainless steel materials should be bonded with soundproof cotton to reduce noise transmission during elevator operation. Finally, the components are numbered and packaged, and their positions are marked in the order of installation for quick on-site assembly.
