电梯门套作为电梯出入口的装饰与防护结构，其制作需兼顾美观性与实用性，在潍坊地区的制作过程中，通常遵循材料筛选、加工成型、表面处理、适配安装四个核心步骤，每个环节的精细操作直接影响最终成品的品质。

　　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、材料筛选与预处理

　　1、 Material screening and pretreatment

　　根据电梯使用场景（如住宅、商场、医院）的不同，选择适配的基础材料。常见材料包括木质复合板、石塑板、不锈钢板等：木质复合板适合温馨风格的住宅电梯，需选用含水率低于 12% 的防潮板材，避免后期变形；石塑板具有耐磨、防火特性，多用于人流量大的商场；不锈钢板则以其耐腐蚀、易清洁的特点，成为医院等场所的优选。

　　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.

　　材料进场后需进行预处理：板材需在通风环境中静置 48 小时以上，使其适应潍坊地区的温湿度（年均湿度 60%-70%），减少后期收缩或膨胀。对于不锈钢板，需用专用清洁剂去除表面油污与氧化层；石塑板则需检查表面平整度，对轻微划痕用细砂纸打磨修复，确保基材无缺陷。

　　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、精准加工与结构成型

　　2、 Precision machining and structural forming

　　首先依据电梯门洞的实际尺寸（宽度、高度、墙体厚度）进行 CAD 图纸设计，确定门套的边框、横头、线条等部件的规格，预留 2-3mm 的安装间隙。切割环节采用数控切割设备，木质复合板与石塑板需使用专用锯片，避免边缘崩裂；不锈钢板则采用等离子切割，确保切口光滑无毛刺。

　　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.

　　折弯成型是关键步骤，对于需要弧度的门套线条（如圆角设计），不锈钢板通过数控折弯机按预设角度（通常为 90° 或 135°）折弯，折弯处需预留 0.5mm 的缓冲空间；石塑板则通过加热软化后定型，冷却后进行边缘修整。拼接部位需加工榫卯结构或预留卡扣槽，确保组装时接缝严密，缝隙控制在 0.3mm 以内。

　　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、表面处理与装饰加工

　　3、 Surface treatment and decorative processing

　　根据设计风格进行表面处理：木质复合板需进行底漆涂刷，选用环保型水性底漆，均匀喷涂 2-3 遍，每遍间隔 4 小时以上，待干燥后用 400 目砂纸轻磨，去除表面颗粒；石塑板可通过热转印技术附着木纹、石纹等图案，转印温度控制在 180-200℃，压力保持 0.3MPa，确保图案清晰且附着力强。

　　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.

　　不锈钢板的表面处理则分为拉丝、镜面、喷涂三种：拉丝处理通过砂带研磨形成均匀纹理，方向需与板材长度一致；镜面处理需经过多道抛光工序，使表面光泽度达到 8K 以上；喷涂处理需先进行磷化处理增强附着力，再喷涂氟碳漆，固化温度控制在 120℃左右，确保涂层耐候性符合潍坊地区的气候要求。

　　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、适配调整与安装准备

　　4、 Adaptation adjustment and installation preparation

　　完成加工的门套部件需在出厂前进行预组装测试，模拟电梯门洞尺寸搭建测试框架，将边框、横头拼接后，检查对角线误差是否在 1mm 以内，垂直度偏差不超过 0.5mm/m。对于存在轻微偏差的部位，用专用打磨工具进行微调，确保整体结构方正。

　　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.

　　安装前的准备工作包括：根据墙体材质（砖墙、混凝土墙、轻钢龙骨墙）准备适配的固定件，如膨胀螺丝、卡扣、胶粘剂等；对门套背面进行防潮处理，木质与石塑材质需涂刷防潮涂料，不锈钢材质则粘贴隔音棉，减少电梯运行时的噪音传导。最后进行编号打包，按安装顺序标注部件位置，便于现场快速组装。

　　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.
