How can a plate be processed layer by layer into a protective shell that can match the product? As a metal shell customization enterprise integrating R & D, design, production, sales and service, jiaruijie model will take you into the production workshop and understand the whole processing steps one by one.

一步：选材

Step 1: material selection

制作一件金属外壳，需要根据设备的使用环境和对防护需求的侧重性进行外壳材质的选择。铝制壳体的优点是重量轻、散热性好、导热性强、可以压铸等，而缺点是坚固性要低于铁质壳体，也偏高。铁质外壳主要是镀锌板为主，优点是低廉、经久耐用、抗挤压能力强，缺点主要是相对较重、耐腐蚀性差、散热弱于铝壳。

To make a metal shell, first of all, the shell material needs to be selected according to the service environment of the equipment and the emphasis on protection requirements. Aluminum shell has the advantages of light weight, good heat dissipation, strong thermal conductivity and die casting, while the disadvantage is that its firmness is lower than that of iron shell and the price is also high. The iron shell is mainly galvanized sheet, which has the advantages of low price, durability and strong extrusion resistance. The disadvantages are relatively heavy, poor corrosion resistance and weaker heat dissipation than aluminum shell.

二步：切割

Step 2: cutting

嘉瑞杰采用激光切割相应板材，通过程序设定使激光切割器将平面板材切割成所需形状。而激光切割的优势也表现在速度快效率高、高精 准度、成本更低等方面。

Jiaruijie uses laser to cut the corresponding plate, and enables the laser cutter to cut the plane plate into the required shape through program setting. The advantages of laser cutting are also reflected in high speed, high efficiency, high accuracy and lower cost.

三步：折弯与压铆

Step 3: bending and riveting

在板材被切割之后是简单的折弯与压铆环节，将整体板材折弯后形成壳体形状。

After the plate is cut, it is a simple bending and riveting link to bend the whole plate to form a shell shape.

四步：表面处理

Step 4: surface treatment

之后是对壳体的表面防护处理，主要的有氧化、喷塑、金属拉丝等方式来对壳体进行防腐蚀和防划处理。

Then is the surface protection treatment of the shell, mainly including oxidation, plastic spraying, metal wire drawing and other methods to carry out anti-corrosion and scratch treatment on the shell.

五步：印字

Step 5: Print

印字是对壳体进行企业logo或者产品信息功能的标识，目前嘉瑞杰采用丝印模板印刷和激光刻字两种方式。

Printing is the identification of enterprise logo or product information function for the shell. At present, jiaruijie adopts two methods: silk screen template printing and laser engraving.

六步：质检发货

Step 6: quality inspection and delivery

嘉瑞杰采用两道质检程序，在各个流程中有过程检，对展品进行各环节的监控，生产结束需要进行完检。在出库前将残次品进行报废或返工，做到99.9%的合格率。

Jiaruijie adopts two quality inspection procedures. There is process inspection in each process to monitor all links of the exhibits. The completion inspection is required at the end of production. Scrap or rework defective products before delivery to achieve 99.9% qualified rate.
