Quality Mgmt. Concept

As an absolutely serious topic, there is no compromise for the standard of product quality. “100-1≠99”, “100-1=0”. Each sectional or tiny quality problem may lead to overall frustration in competition. That is why we must work very hard on every portion and detail to make sure our products with no defect.
All the products we provide strictly comply with the regulations and standards of ISO9001 and TS16949. Excellent product quality is achieved by strict by strict control programs and adequate management. To meet demands from customers all over the world, we are always working on eliminating defects.

Quality Control Process

UMAG focuses on process design and optimization before production. Committed to discovering, controlling and solving problems especially those occur during the process, UMAG prevents problems with quality tools such as APQP etc, and strictly implement VDA6.3 during production. Furthermore, in order to prevent the outflow of defective products, UMAG applies double sampling inspection to all products.
Besides the ordinary tests on dimensions, surface magnetic induction intensity, and magnetic flux, UMAG is also equipped with many professional testing and analytical equipment for various applications.
Projector: can test the dimensions and geometric tolerances of complex shapes, to ensure the high assembly accuracy of finished products.
High temperature curve tester: can test the properties at high temperature to help the customers analyze the different performance of motor output power at different temperatures.
Magnetic declination tester: can test the magnetic declination to help the customers analyze and evaluate different magnetic declination’s effects on motors or sensors.
Coating thickness tester: can test the electroplating quality in bulk without damaging the coatings, to ensure the service life of products.
HAST tester: can accelerate the simulation of the use of magnets in harsh environments. Weight loss <2mg/cm? after 168 hours in the environment of 130℃ 2.6Bar atmospheric pressure and 95% humidity is equivalent to running for over 15 years in the normal operational environment of motors.
Shear force tester: can simulate the adhesive force between magnets and glue when the magnets are installed in motors, and can also test the bonding power of magnetic assemblies to help customers optimize cost.

Tools for Quality Mgmt

1. SPC,Statistical Process Control; 2. MSA,Measurement System Analysis; 3. FMEA,Failure Mode & Effect Analysis; 4. APQP,Advanced Product Quality Planning; 5. PPAP,Production Part Approval Process.
SPC: A process control tool applying mathematical statistics. SPC analyzes and evaluates the production process, discovers the signs of systematic factors, and takes measures to eliminate their effects, in order to maintain the process and quality under control.
MSA: a specially designed?experiment?with mathematical statistics and charts that analyzes the resolution and errors of the measuring system, in order to evaluate whether they fit the measured parameters, and to determine the main component of the errors of the measuring system.
FMEA: a sort of systematic activities that analyzes each procedure of the whole process and the subsystems and parts of the products at the product design stage and the process design stage, discovers all the potential failure modes, analyzes their possible consequences, and then takes the necessary measures in advance, in order to improve the quality and reliability of the products. Design FMEA and process FMEA are the most frequently used.
APQP: Advanced Product Quality Planning, a part of TS16949 Quality Management System. Product quality planning is a structured method with the purpose of ensuring all the required steps be completed on time by improving the connection with each person involved. Effective product quality planning depends on the top management’s commitment to customers’ satisfaction.
PPAP: Production part approval process, is one of 5 core tools required by ISO/TS quality management system applied in automobile industry. The main effect of PPAP is to ensure the quality ability in the production process can meet customers’ requirement by reviewing the multiple outputs of APQP and providing enough guarantee for customers. PPAP is a control program for the production parts, and also a quality management method.
