A good aluminum oxide plate manufacturer will carry out dimensional inspection and quality control during the production process to ensure that the quality of the product is stable and meets customer requirements. The following will describe in detail the methods and steps of dimensional inspection and quality control of aluminum oxide plate manufacturers.

1. Size inspection method

In the production process of aluminum oxide sheet, the size inspection is a very key link. On the one hand, the correct size can ensure that the product can be installed and used correctly; On the other hand, the accuracy of the size can also determine the precision and process level of the product manufacturing.

1. Check the first piece

In the early stage of the production of aluminum oxide sheets, the first piece inspection is required. The first piece is the first piece of product before the start of the production task, through the size check of the first piece, you can determine whether the product meets the requirements, and whether the process is working properly. The first inspection needs to be carried out before the production of the product, and is usually completed during the installation and commissioning phase.

The first inspection steps are as follows:

(1) Preparation and calibration: First, prepare the tools and instruments required for inspection, such as measuring tools, micrometers, micrometers, etc. These tools are then verified to ensure that they are accurate. The method of verifying a tool is generally to compare it with a measuring tool of known accuracy.

(2) Check the size of the first piece: Take out the first piece and check the size according to the process requirements. The dimensions to be checked are generally length, width, thickness, etc.

(3) Record size data: the size data obtained from the inspection is recorded, generally presented in the form of charts.

(4) Handling abnormal products: If the first piece has a size deviation or other abnormal conditions, it needs to be adjusted or remade in time.

(5) Complete the report: complete the first inspection report according to the test results and adjustments.

2. Incoming material inspection

In the production of aluminum oxide sheets, the quality and size of raw materials are also very important. Through the incoming inspection of raw materials, it can be ensured that the quality and size of raw materials meet the requirements, so as to ensure the quality of products. The steps of incoming inspection are as follows:

(1) Preparation and calibration: It is also necessary to prepare the tools and instruments required for inspection, and verify them.

(2) Select samples for inspection: Select a certain number of samples from raw materials for inspection. The number of samples is generally determined by the yield and dimensional stability of the desired product.

(3) Check the size of the sample: check the size of the sample according to the process requirements, and record the inspection results.

(4) Handling abnormal samples: If there is a size deviation or other abnormal situation in the sample, it is necessary to communicate with the supplier and deal with it.

(5) Completion report: According to the test results and processing conditions, complete the incoming inspection report.

3. Check online

In addition to the first part inspection and feed inspection, the production process of aluminum oxide sheet also needs to be checked online to monitor and control the size of the product. The online check steps are as follows:

(1) Preparation and calibration: It is also necessary to prepare the tools and instruments required for inspection, and verify them.

(2) Select samples for inspection: Select a certain number of samples from the production line for inspection, generally based on the output of the required product.

(3) Check the size of the sample: check the size of the sample according to the process requirements, and record the inspection results.

(4) Handling abnormal samples: If there is a size deviation or other abnormal situation in the sample, timely adjust the production process or equipment to ensure product quality.

(5) Complete the report: according to the test results and processing, complete the online inspection report.
