The functions and contents of plastic product quality inspection

The functions and contents of plastic product quality inspection are as follows:


Quality inspection of plastic products by plastic manufacturers is an important component of quality control of Plastic Product molding and processing. It is a very important process in plastic part production. It is used to determine the quality characteristics of plastic parts through certain methods and means, and compare the measurement results with the specified quality standards of plastic parts to judge whether the plastic part passes or fails.


(1) Functions of quality inspection

The main purpose of quality inspection is for plastic manufacturer to determine whether Plastic Products meet quality standards, detect non-conforming products through testing, and prevent users (including downstream processes) from providing products or semi-finished products that do not meet standard requirements. Therefore, quality inspection has the following main functions:


1) Guarantee function. Through inspection and testing, non-conforming products are eliminated to ensure that semi-finished or finished products that do not meet quality standards are detected. Strictly guarding and ensuring quality to maintain reputation.


2) Preventive function. Using advanced inspection methods and inspection techniques to understand potential problems in a process that may affect plastic part quality, thereby preventing the manufacture of final products that do not meet quality requirements.


3) Reporting function. Quality management personnel record the data and situations obtained during the inspection work in detail, analyze and evaluate relevant situations, and report to relevant departments.


(2) Contents of quality inspection

Quality inspection is a very delicate work that must be carried out according to established requirements. The main contents are as follows:


1) Measurement. Accurately detect and record the processed injection molded products or samples.


2) Comparison. Compare the measurement results of plastic parts with the specified inspection standards to determine the quality characteristics of the plastic part.


3) Judgment. Determine whether the inspected plastic part or batch passes based on the comparison with quality standards.


4) Processing. After inspection is completed, qualified plastic parts are retained, disposal opinions are made for non-conforming plastic parts, or quality feedback information is issued to downstream processes or molding and processing suggestions are proposed.


5) Record. Record the inspection results of plastic parts and feedback to relevant departments, requiring them to improve quality.
