　　充气拱门作为庆典、展会等场景的常用装饰，其从设计到制作需经过多道精细工序，兼顾美观性与实用性，确保使用时既醒目亮眼，又能稳定矗立。

　　Inflatable arches, as a common decoration for celebrations, exhibitions, and other occasions, require multiple meticulous processes from design to production, balancing aesthetics and practicality, ensuring that they are both eye-catching and stable when used.

　　设计构思是流程的起点，需结合使用场景与功能需求。首先确定拱门尺寸，常规庆典用拱门高度多为 6-8 米，跨度 10-15 米，小型活动则可选 3-5 米高的便携款，尺寸需与场地空间匹配，避免过大导致安装困难或过小显得突兀。造型设计上，基础款为对称弧形，可添加装饰元素如云朵边、波浪纹，或融入主题图案（如节日庆典加灯笼、企业活动嵌标志），图案需简洁醒目，远距离仍能清晰识别。色彩搭配需贴合场景氛围，红色、金色适合喜庆场合，蓝白配色多用于展会，同时考虑色彩饱和度，确保阳光下不褪色、夜间灯光照射下不失真。设计完成后，需用矢量软件绘制 1:1 图纸，标注各部位尺寸、拼接位置及图案坐标，为制作提供精准依据。

　　Design concept is the starting point of the process, which needs to be combined with usage scenarios and functional requirements. Firstly, determine the size of the arch. For regular celebrations, the height of the arch is usually 6-8 meters, with a span of 10-15 meters. For small events, a portable version that is 3-5 meters high can be selected. The size should match the space of the venue to avoid installation difficulties caused by being too large or too small, which may appear abrupt. In terms of styling design, the basic model is a symmetrical arc shape, which can add decorative elements such as cloud edges, wave patterns, or incorporate theme patterns (such as adding lanterns to festivals and corporate event logos). The patterns should be simple and eye-catching, and can still be clearly recognized from a distance. The color matching should be in line with the atmosphere of the scene. Red and gold are suitable for festive occasions, while blue and white colors are mostly used for exhibitions. At the same time, color saturation should be considered to ensure that it does not fade under sunlight and does not distort under nighttime lighting. After the design is completed, it is necessary to use vector software to draw 1:1 drawings, marking the dimensions of each part, splicing positions, and pattern coordinates to provide accurate basis for production.

　　材料甄选直接影响拱门质量与耐用性。主体材料多选用 PVC 夹网布，其由经纬网布中间夹 PVC 膜复合而成，厚度需达 0.4-0.6mm，抗拉强度≥200N/5cm，确保充气后不鼓包、不变形。面料需具备良好的气密性（24 小时漏气量≤5%）和耐候性，能抵御阳光直射、雨水浸泡而不老化，低温环境（-10℃）下不脆化开裂。图案印刷材料选用环保油墨，通过丝网印刷或热转印技术附着在面料表面，油墨层需与基布结合牢固（附着力≥3 级），反复摩擦不脱落，且符合无异味、无重金属的安全标准。配件材料如拉链（选用防水拉链，拉合顺畅不卡滞）、气嘴（黄铜材质，密封性能好）也需严格筛选，避免因小部件损坏影响整体使用。

　　The selection of materials directly affects the quality and durability of the arch. The main material is often PVC mesh cloth, which is composed of a composite of warp and weft mesh cloth with PVC film sandwiched in between. The thickness should reach 0.4-0.6mm, and the tensile strength should be ≥ 200N/5cm to ensure that it does not bulge or deform after inflation. The fabric should have good air tightness (24-hour air leakage ≤ 5%) and weather resistance, be able to resist direct sunlight and rainwater immersion without aging, and not become brittle or crack in low temperature environments (-10 ℃). The pattern printing material uses environmentally friendly ink, which is attached to the surface of the fabric through screen printing or heat transfer printing technology. The ink layer needs to be firmly bonded to the base fabric (adhesion ≥ 3 levels), repeatedly rubbed without falling off, and meets the safety standards of no odor and no heavy metals. Accessory materials such as zippers (using waterproof zippers for smooth and non sticking closure) and air nozzles (made of brass with good sealing performance) also need to be strictly screened to avoid damage to small components that may affect overall use.

　　裁片与拼接是制作的核心环节。根据设计图纸，用裁床将面料精准裁剪成各部件（弧形顶、两侧立柱、装饰边等），裁片误差控制在 ±1cm 以内，确保拼接后造型规整。拼接采用高频热合工艺，通过高频电流使面料接触面融化后粘合，接缝宽度≥1cm，热合强度≥150N/5cm，比缝纫更能保证气密性。弧形顶部是拼接难点，需将多块裁片按弧度渐变拼接，热合时用模具固定形状，避免扭曲变形。图案印刷在裁片阶段完成，印刷位置需与设计图纸对齐，偏差不超过 5mm，复杂图案需分色套印，确保色彩衔接自然。对于带文字的拱门，文字排版需清晰易读，字号大小根据观看距离设定（10 米外可见的文字字号不小于 30cm）。

　　Cutting and splicing are the core processes of production. According to the design drawings, use a cutting machine to accurately cut the fabric into various components (curved top, two side columns, decorative edges, etc.), with a cutting error controlled within ± 1cm, ensuring that the shape is neat after splicing. The splicing adopts high-frequency heat sealing technology, which melts the fabric contact surface through high-frequency current and bonds it together. The seam width is ≥ 1cm, and the heat sealing strength is ≥ 150N/5cm, which can ensure better airtightness than sewing. The curved top is the difficulty of splicing, and multiple pieces need to be gradually spliced according to the curvature. When heat sealing, the shape should be fixed with a mold to avoid distortion and deformation. Pattern printing is completed during the cutting stage, and the printing position needs to be aligned with the design drawings, with a deviation of no more than 5mm. Complex patterns need to be color coded and overprinted to ensure natural color matching. For arches with text, the text layout should be clear and easy to read, and the font size should be set according to the viewing distance (the font size of visible text from 10 meters away should not be less than 30cm).

　　充气测试与修整保障使用性能。拼接完成后进行首次充气测试，充气压强控制在 0.02-0.03MPa（用压力表监测），静置 24 小时观察是否漏气，重点检查接缝处、气嘴周边有无气泡溢出，漏气点需用专用胶修补（胶层厚度 0.3-0.5mm，固化 24 小时后再测试）。测试时同步检查造型是否符合设计，如拱门两侧是否对称、弧度是否流畅，必要时通过调整局部拼接位置修正。配件安装后再次测试，拉链闭合后需保证气密性，气嘴连接充气泵后充气速度应满足 5 分钟内达到额定气压，阀门关闭后能保持压力稳定，确保使用时无需频繁补气。

　　Inflatable testing and repair ensure performance during use. After the splicing is completed, the first inflation test shall be carried out, with the inflation pressure controlled at 0.02-0.03MPa (monitored by a pressure gauge), and left to stand for 24 hours to observe whether there is any air leakage. The focus shall be on checking whether there are any bubbles overflowing from the joint and around the air nozzle. The air leakage point shall be repaired with special adhesive (adhesive layer thickness of 0.3-0.5mm, cured for 24 hours before testing). During testing, synchronously check whether the shape conforms to the design, such as whether the two sides of the arch are symmetrical and the curvature is smooth. If necessary, adjust the local splicing position to correct it. After installing the accessories, retest to ensure airtightness after the zipper is closed. After connecting the air nozzle to the inflation pump, the inflation speed should reach the rated pressure within 5 minutes. After the valve is closed, the pressure should remain stable to ensure that there is no need for frequent air supply during use.
