    While improving the system, the company also attaches importance to personnel training and arranges senior teachers for training, so that employees can better use and understand the five tools of quality management.

APQP Training

    Quality management five tools, also known as quality control five tools. Include:

  • SPC (Statistical Process Control);

  • MSA, Measurement System Analyse;

  • FMEA, Failure Mode & Effect Analyse;

  • Advanced Product Quality Planning (APQP);

  • Production Part Approval Process (PPAP)

    Using the five quality tools can make a project go more smoothly.


    SPC(Statistical Process Control) is a manufacturing Control method, which combines the data collected by the Control items in the manufacturing according to their characteristics, analyzes and standardizes the Process capability, explores the abnormalities in the Process, and immediately takes improvement measures to restore the Process to normal.

    Using statistical methods to monitor the state of the manufacturing process, determine the production process under the control of the state, in order to reduce the product quality variation SPC can solve the problem 1. Economy: effective sampling control, no full inspection, failure rate, to control the cost. Stable process, quality, cost and delivery. 2. Early warning: the abnormal trend of the process can be taken immediate measures to prevent the whole batch of bad, so as to reduce waste. 3. Identify special causes: as a reference for local problem countermeasures or management system improvement. 4. Make good use of machinery and equipment: estimate the machine capacity and arrange appropriate machines to produce appropriate parts. 5. Evaluation of improvement: process capability can be used as an indicator for comparison before and after improvement.


    · Make a reliable and effective assessment of the process;

    · Determine the statistical control boundary of the process, and judge whether the process is out of control and whether the process is capable;

    · Provide an early warning system for the process to monitor the process in time to prevent the occurrence of waste;

    · Reduced the dependence on routine inspection. Timed observation and systematic measurement methods replaced a large number of detection and verification work


    Measurement System Analysis (MSA) is the analysis of a measuring system with repeated readings for each part, to assess the quality of the measuring system and to determine the acceptability of the data generated by the measuring system.

MSA (MeasurementSystemAnalysis) using the method of mathematical statistics and charts and resolution of the measurement system error is analyzed. To assess whether the resolution and error of the measurement system are appropriate for the parameters being measured and to determine the major components of the measurement system error.

    In daily production, we often analyze the state of the process, the ability of the process and monitor the change of the process according to the measurement data of the process parts. So, how do you make sure the analysis is correct? We have to do this in two ways:

    1. To ensure the accuracy/quality of the measurement data, use the measurement system analysis (MSA) method to evaluate the measurement system that obtained the measurement data;

    2. To ensure the use of appropriate data analysis methods, such as the use of SPC tools, experimental design, analysis of variance, regression analysis, etc.

Purpose of MSA:

    Understand the measurement process, determine the total amount of error in the measurement process, and evaluate the adequacy of the measurement system used in production and process control. MSA promotes understanding and improvement (reduces variability).

MSA uses mathematical statistics and graphing methods to analyze the resolution and error of the measurement system to assess whether the resolution and error of the measurement system are appropriate for the parameters being measured and to determine the major components of the measurement system error.


    When designing and manufacturing a product, there are usually three lines of defense to control defects: to avoid or eliminate the cause of a fault, to predetermine or detect a fault, and to minimize the impact and consequences of a fault. The FMEA is an effective tool to help us eliminate defects in the cradle from the first line of defense. FMEA is an important method of reliability design. It is actually a combination of FMA (Failure Mode Analysis) and FEA (Failure Impact Analysis). It evaluates and analyzes potential risks in order to eliminate them or reduce them to an acceptable level based on existing technology. Timeliness is one of the most important factors in the successful implementation of FMEA, it is an "ex ante behavior", rather than an "ex post behavior". To achieve the best benefit, the FMEA must be performed before the failure mode is incorporated into the product. FMEA is actually a series of activities, its process includes: identify the potential failure mode of the product/process; According to the corresponding evaluation system to identify the potential failure mode risk quantitative assessment; List the cause/mechanism of the failure and identify preventive or corrective actions. Because product failure may be related to design, manufacturing process, use, contractor/supplier and service, so FMEA is subdivided into design FMEA, process FMEA, use FMEA and service FMEA four categories. Among them, design FMEA and process FMEA are most commonly used.

    The purpose of FMEA

    1) The product or process can be modified easily and at low cost, so as to reduce the crisis of post-revision.

    2) Find measures that can avoid or reduce the occurrence of these potential failures.


    Product quality advance planning (or product quality advance planning and control plan) is a part of QS9000/TS16949 quality management system. Definition and other knowledge: product quality planning is a structured approach to identifying and setting out the steps required to ensure that a product will satisfy customers. The goal of product quality planning is to facilitate contact with everyone involved to ensure that the required steps are completed on time. Effective product quality planning depends on top management's commitment to the purpose of striving to achieve customer satisfaction.




    The Production Part Approval Process (PPAP) is a practical technique which aims to verify that the products manufactured by the manufacturing tooling and process meet the technical requirements through product approval and approval procedures prior to the shipment of the first batch of products.

PPAP production parts to submit the guarantee: mainly include production parts size inspection report; Appearance inspection report; Functional inspection report; Material inspection report; In addition, some parts control methods and supplier control methods; Mainly, manufacturing enterprises require suppliers to make PPAP documents and the first piece when they submit products, and they can only submit after all PPAP documents are qualified. A report shall also be submitted when engineering changes are made.

    PPAP is a control procedure for production parts and also a management method for quality.

    The purpose of the PPAP

    1) Determine whether the supplier has correctly understood all requirements of the customer's engineering design records and specifications.

    2) and has the potential to continuously meet these requirements during the actual production process under the conditions of the required production tempo.
