肯德基门了传统铝合金门和玻璃门使用过程中门扇容易下垂变形或易位的问题，使用寿命更长久。铝合金型材采用特殊加厚加宽设计，成品组装而且全部采用不锈钢紧固件紧固，门扇角部采用加厚铝合金槽形角码连接，连接处采用高频氩弧铝焊接，使结构连接更牢固、抗冲击。肯德基门线条简洁流畅、造型时尚高雅，是现代商用门的更新换代佳选。

KFC doors solve the problem of traditional aluminum alloy doors and glass doors that are prone to sagging, deformation, or displacement during use, resulting in a longer service life. The aluminum alloy profiles are specially thickened and widened. The finished products are assembled and fastened with stainless steel fasteners. The corners of the door leaves are connected with thickened aluminum alloy slot shaped corner pieces. The joints are welded with high-frequency argon arc aluminum to make the structural join more secure and impact resistant. KFC doors have simple and smooth lines, fashionable and elegant designs, making them a great choice for modern commercial doors.

现在来讲讲济南肯德基门的制作工艺：

Now let's talk about the manufacturing process of Jinan KFC doors:

丝接工艺：

Wire connection process:

也就是常说的穿引丝工艺，在上下方中穿进一根钢筋拉丝，通过两头毛企的螺丝固定门扇成型，但必须是国标丝（为什么必须是国标丝？因为这个工艺是挤压拉力作用，非国标非常容易脱丝）。

This is also commonly known as the threading process, where a steel bar is threaded into the upper and lower middle, and the door leaf is formed by fixing it with screws at both ends. However, it must be a national standard wire (why must it be a national standard wire? Because this process is subjected to compression and tension, non national standard wire is very easy to detach).

优点：成本低，组装快。

Advantages: Low cost, fast assembly.

缺点：对于工作台的要求严格，表面必须非常平整，穿上穿引丝以后两端同时拧丝，毛企和上下方接触的地方出现才会平整，这就是刚才说的为什么要求工作台必须平整，且工作台一定能完整拼装一扇门，拧到不太紧之后，开始用高频氩弧铝焊接，焊接后再重新拧紧螺丝，达到固定的目的。

Disadvantages: The requirements for the workbench are strict, and the surface must be very flat. After threading the guide wire, both ends must be tightened at the same time, and the areas where the burrs and the upper and lower parts come into contact will be flat. This is why the workbench must be flat, and it must be able to fully assemble a door. After tightening it not too tight, start using high-frequency argon arc aluminum welding, and then retighten the screws to achieve the purpose of fixation.

必须焊接，因为是用高频氩弧铝焊对于焊工技术的要求比较高，同时由于该工艺的组装是挤压力使得门扇成型，四边形具有不稳定性，这里就不赘述，所以关键点都放在焊接上，一旦焊接不合格，门用没多久就会开焊导致变形。

Welding is necessary because high-frequency argon arc aluminum welding requires high welding skills for the welder. At the same time, the assembly of this process involves extrusion pressure, which causes the door leaf to form and the quadrilateral shape to be unstable. Therefore, the key points are all placed on the welding. Once the welding is not qualified, the door will not be used for long and cause deformation.

挤压成型的门扇必然会有变形和毛企与上下方错位的情况，不要紧张，重新找个平整的地方组装就好，例如放到玻璃上拼装。

The extruded door leaf will inevitably have deformation and misalignment with the upper and lower parts. Don't be nervous, just find a flat place to assemble, such as placing it on glass for assembly.

免焊接工艺：

Welding free process:

是品创早期设计的一款肯德基门制作组装工艺，集合了穿引丝工艺的优点，摒弃了其缺点，以致造就现在的新工艺。

It is a KFC door manufacturing and assembly process designed by Pinchuang in the early stage, which combines the advantages of threading technology and eliminates its disadvantages, resulting in the creation of the current new process.

免焊与穿引丝的区别：

The difference between welding free and threading wire:

1。组装方式：直接在凳架组装就可以，抛开了组装操作台的限制，穿引丝工艺必须在平整的案板上进行，实在没有，那就找块大玻璃。如果是在工程工地组装，也不受当时条件限制，一个电钻一个皮锤一个人轻松搞定。如果穿引丝的工艺对工作台的要求上就必须保持地面清洁，没有砂砾，少2人同时用力，保证门体不变形。

1。 Assembly method: Simply assemble on the stool frame. Regardless of the limitations of the assembly console, the threading process must be carried out on a flat cutting board. If there is no such process, then find a large piece of glass. If it is assembled on an engineering site, it is not limited by the conditions at that time, and can be easily handled by one person, one electric drill and one leather hammer. If the process of threading wire requires the workbench to be kept clean and free of sand and gravel, and two people should exert force simultaneously to ensure that the door body does not deform.

2。受力影响：在不焊接的情况下，穿引丝工艺是不能安装玻璃的，这样整扇门所有的受力点都集中在焊接上，日久生变。反观免焊工艺，是通过四道螺丝直接固定，就可以直接装玻璃安装，再加上铝焊接加固，这样的焊接只起到加固的作用，整扇门的重力分散给了两侧举脱力的螺丝。相对耐久性不言而喻！

2。 Affected by force: Without welding, the threading process cannot install glass, so all the force points of the entire door are concentrated on the welding, which will change over time. On the other hand, the welding free process is fixed directly with four screws, allowing for glass installation. In addition, aluminum welding is used for reinforcement. This welding only serves the purpose of reinforcement, and the gravity of the entire door is distributed to the screws with lifting force on both sides. The relative durability is self-evident!
