quality control checks Flashcards
Visual Inspection
the process of looking over a piece of equipment using the naked eye to look for flaws.

Mould markings
check if there is any marks on the mould- get rid of moulds that are ruined or adjust them
Mould temperature monitored and adjusted using cooling
Mould temperature monitored and adjusted using cooling
what is the six sigmas
step 1: define the issue with the process
step 2:measure-take steps to measure the extent of the issue
step 3:analyse- determine where the issues reassured occur
step 4 improve- introduce procedures to rectify the issues identified
step 5: control -ensure the modified procedure are implemented and maintained through effective quality assurance procedures.

Use of mould flow analysis prior to mould design to check polymer

what is Quality Control (QC)
The monitoring, checking and testing of materials components, equipment and products throughout production to ensure they conform to acceptable tolerances.
Visual checks to check for obvious aesthetic defects
- Stress testing to check for internal defects.
- Destructive interval testing on a production line.
is a technique used in all areas of manufacturing. It is a technique used to check quality against a set standard or specification. It may be used to check the dimensions of a product or component. We say that the component has been checked to ensure that it is within accepted tolerances (acceptable variations of sizes which stray from the optimum size).
QC requires constant inspection throughout the manufacturing process in order to detect products which are not up to the required standard. These inspections are also carried out on the completion of a product by trained inspectors.
Quality Assurance (QA The procedures and policies put in place to reduce waste and ensure manufactured products are produced accurately within set acceptable tolerances.
for example Accurate dimensioned engineering drawings being used for checking dimensional accuracy.
- Setting temperature tolerances for materials during forming processes.
- setting regularity of mould changes to avoid excessive wear
is a a companies guarantee that the product or service it offers meets the accepted quality standards. The planned checking procedures take place ‘before, during and after’ and the aim is to get it ‘ right first time, every time’. Quality Assurance must be the responsibility of everybody involved in the creation of a product or service. QA must be built into every stage of product development and every stage of the manufacturing process.
total Quality Management (TQM)
takes Quality control even further. Its aim is to create a Quality Culture . A company that embraces (TQA) is a company that is continually attempting to improve its products and its performance. Customers tend to be loyal to this type of organisation.
