鈑金加工行業通常具有批量小、品種多的特征，機箱外殼正是應用了這種特征，鈑金加工質量非常難控制，若要把握產品加工質量，須掌握以下幾點：

The sheet metal processing industry usually has the characteristics of small batches and multiple varieties. This feature is precisely applied to the chassis casing, and the sheet metal processing quality is very difficult to control. To grasp the product processing quality, it is necessary to grasp the following points:

當我們接到機箱外殼的訂單時一定要做了解，比如，用戶對其產品的外觀要求，尺寸要求，以及產品用途等。

When we receive an order for a chassis shell, we must have a comprehensive understanding, such as the user's requirements for the appearance, size, and purpose of the product.

了解完用戶對產品的需要，我們根據不用用戶的產品選擇不同的工藝，同時在設計圖紙中說明注意事項。講圖紙拿到工程部進行制作工藝圖，工藝員畫好圖紙要經過另外員工檢查，待檢查完畢后要經過簽字確認后發給車間。

After understanding the user's needs for the product, we choose different processes based on the products of different users, and note the precautions in the design drawings. Take the drawings to the Engineering Department for production of process drawings. After the technician draws the drawings, they must be inspected by another employee. After the inspection is completed, they must be signed and confirmed before being sent to the workshop.

數控下料，數控下料首件要進行過全檢，（數控沖，金屬激光切割機等）下料的工件進行檢查，包括尺寸，展開等。大批量生產時必須全部首件檢驗合格了才能批量生產。

CNC blanking: The first piece of CNC blanking must undergo a full inspection. (CNC punching, metal laser cutting machines, etc.) The workpiece to be blanking must be inspected, including dimensions, unfolding, etc. During mass production, all first article inspections must be passed before mass production can be conducted.

折彎時要對折彎方向及折彎尺寸進行首件確認，確認完畢后開始批量生產，更換操作工或更換模具時要重新檢驗。完成品，對焊接完成品或折彎完成品根據圖紙要求對尺寸進行抽樣檢查，抽樣檢查時要對每個尺寸進行確認。同時要對外觀進行全檢，對不合格的要及時調整，再次檢查。同時填寫檢驗報告單。

During bending, the bending direction and bending size should be confirmed for the first piece. After confirmation, batch production should be started. When changing the operator or mold, a new inspection should be conducted. For finished products, sampling inspection shall be conducted for the size of finished welding or bending products according to the drawing requirements, and each size shall be confirmed during sampling inspection. At the same time, conduct a full inspection of the appearance, and timely adjust and recheck the unqualified parts. Fill in the inspection report at the same time.

表面處理，對表面處理的產品外觀進行全檢。發貨，未通過檢驗的產品不得發貨。首件要求操作工報檢，完成品同樣有操作工報檢，檢驗合格后有檢驗員簽字后才能人庫。如操作工不報檢，此批產品沒有工費。雖然客戶的訂單急，忽必保證較高品質，較快速度的鈑金加工理念。

Surface treatment: conduct a full inspection of the appearance of the surface treated product. Shipment. Products that have not passed the inspection shall not be shipped. The first article requires an operator to apply for inspection, and the finished product also requires an operator to apply for inspection. After passing the inspection, the inspector can sign before entering the warehouse. If the operator does not apply for inspection, there will be no labor cost for this batch of products. Although the customer's order is urgent, it is necessary to ensure a high quality and faster sheet metal processing concept.

現在的鈑金加工產品越來越多，如何去分辨鈑金加工產品的優劣是我們必要的技能。

Nowadays, there are more and more sheet metal processing products, and how to distinguish the advantages and disadvantages of sheet metal processing products is a necessary skill for us.
