Even the most conscientious worker can only maintain a high standard of product quality when supported by plant and equipment capable of consistently meeting these standards.influence on product Q amp。 e high degree of process control available and the cleanliness of application are,however,two features which make the use of electricity very suitable and sometimes essential in the manufacture of products of high quality and reliability. Every function within a factory can be said to have some influence on the saleability of the final product. Some of these function s are often regarded as an indirect overhead without rearising the important part they play in achieving a high quality and airconditioning, which can effect the efficiency of work people, are two possible a great deal depends upon the product design and the production methods adopted, and both must be kept unde r constant review.Q amp。 R with better lightingAs mentioned previously,the contribution made by good lighting to the quality of a product is not always appreciated. In the manufacture of ornamental tiles,flaws such as deformation, chips cracks etc are inevitable however carefully the process is detecting these faults in tiles at an early stage further expensive and wasteful processing is avoided and the final product quality is improved. The result so f an investigation by one wellknown pany revealed that 20% of the faulty tiles escaped detection during manufacture, even the at the final inspection stage only 2163。% of the faulty tiles found their way on to the market. This obviously would not do. The lighting level was generally proved totgive 60lumens/ of 1015 lumens/ early production processes and 140 lumens/.For final clour quality of the light was also improved. The result is that only 4% of all faulty tiles reach final inspection and 2% are rejected there. Moreover, clour vision in the final stage is now so good that some tiles rejected for offclour can be accurately regraded according to their shade and sold as seconds . The ability to see clearly that quality goods are being made and its aid to inspection are not the only gain from good lighting. Many panies also list reduced safety hazards and improved working conditions which create good relations between management and workpeople. This, in turn is reflected in a more efficient working unit.improved Q amp。s production potential. Metallurgically it is more flexible than the cupolas it replaces and is producing a superior analysis resulting in less scrap .It is worthy of note that as a result of tests, carried out in cooperation between the pany and engineers of the North Western Electricity Board, the Electricity Board were able to remend a satisfactory method of working which would take advantage of the industrial tariff structure and reduce the pany39。 own engineers after a prehensive investigation into the many problems involved .Production of tinplate, which is produced at a continuous strip speed of up to 1,250 ft. per minute, is monitored and a detailed record made of all flaws during the tinning process , together with a puted average gauge of the steel strip and average thickness of the tin coating of each surface. In this way a plete coilbycoil analysis of tin plate production of each shift is provided with a view to improving product quality and reducing material wastage throughout the tinning operation.In addition , two separate statements for every coil are produced one showing the total amount o f defective tin plate contained in the coil , and the other the location of the various flaws within it. By this means the tinplate user is able to avoid the use of unsuitable raw materials with corresponding improvement in quality potential.Q amp。 s finish rightly or wrongly, is often taken as a standard of the quality of the product as a whole. Even when it does not contribute markedly to the reliability or function of the product it must be right for the customer. Electrical processes can contribute in many ways to improving finish and is a field of application in which many technological changes have taken place in recent years. The finish on hand tools is by no means an insignificant factor in their sales appeal. It also needs to be durable to survive the rough usage to which the tool will be exposed . One major hand tool manufacturer sought to increase his productivity while maintaining at least the same level of quality he was obtaining with his existing methods. Dipping and spraying methods were considered but the former suffered from paint runs on the lettering cast into the handles and the latter required too high a labor force.The solution was finally found to be an electrophoretic painting process. This is an electric painting process operating on similar principles to electroplating .The five principle advantages found with this metho d are :1. Good control of film thickness。3 . Freedom from runs and sags。5. Freedom fro m solvent washing in box sections .Although this new painting method gives an attractive finish befitting a quality engineer39。 R in design and manufacture to note and assess all these changes in the light of their own requirements .While Q amp。s Q amp。 R within the pany.
