Zero Error Quality
Quality is the main concern for the development of products which leads to global trust. Providing the international quality to cater to all social & mechanical norms is the mainstay to impress the human system with demanding products. We at Universal Buying Service are religiously involved to provide you the infallible quality not only in products but also in other services for satisfaction by following all international rules, regulations & standards.

Quality Eye

Quality one of the most important terms in service industry is of utmost importance to all of us at Universal Buying Services. Strict quality standards conforming to ISO 9002 are practiced at UBS. The quality aspects keep getting rigorous and more process driven with the passage of each day. We always attempt to broaden the scope of our goods & services and make an endeavour to provide quality merchandize.

The Quality Inspection Process is done by inhouse experts equipped with latest inspection tools like moisture meter, rust analyzer, floor balancing and mercury meter etc. The process is divided into three basic stages for a 100% guarantee of an error free product designed as per client specifications.

• During Production at the vendor factory
• Before Packing after the production is finished
• At the time of Stuffing

After each stage of inspection, we issue a quality report that is immediately sent to you by fax or e-mail to apprise you of the status and take necessary feedback. The report can also be accessed online through web tracking round the clock. We believe in 100% level of Client Satisfaction and to ensure that our quality process protects our clients, from any kind of risk.

Definition & Concept
• An item or component or product which is manufactured is required to perform certain functions. The
  act of checking whether a component actually does so or not is called inspection.
• In other words, inspection means checking the acceptability of the manufactured product.
• Inspection measures the qualities of a products or service in term of predecided standards. Product
  quality may be specified by its strength, hardness, surface finish, chemical compositions,
  dimensions, etc.

Purpose & Objectives of inspection are:
(i) Inspection separates defective components from non-defective ones and thus ensures the adequate
   quality of products.
(ii) Inspection locates defects in raw materials and flaws in process which otherwise cause problems at
    the final stage. For example, detecting the parts not having proper tolerances during processing itself
    will minimize the troubles arising at the time of assembly.
(iii) Inspection prevents further work being done on semi finished products already detected as spoiled.
(iv) Inspection makes sure that the product works and it works without hurting anybody, i.e., its
     operation is safe.
(v) Inspection detects sources of weakness and trouble in the finished products and thus checks the
    work of designers.
(vi) Inspection builds up the reputation of the concern as it helps reducing the no of complains from the


Kinds Of Inspection
(a) Roving, Process, Patrolling or floor inspection.
(b) Fixed inspection
(c) Key point inspection, and
(d) Final inspection.

(a) Roving inspection
• The inspector walks round on the shop floor from machine to machine and check samples of the work
   of various machine operators or workers.
• Floor inspection:

(i) Helps catching errors during process itself, i.e., before the final production is ready; and
(ii) It is more effective and desirable because the work need not be transported to a centralized (inspection) place.

(b) Fixed Inspection:

• The work is brought at intervals for inspectors to check
• Fixed inspection discovers defects after the job has been completed.
• Fixed inspection is used when inspection equipments and tools can not be brought on
  the shop floor.
• It is a sort of centralized inspection, the worker and the inspector do not come in
  contact with each other; thus it eliminate any changes of passing a doubtful product.

(c) Key-point inspection:
• Every product (more or less) has a key point in its process of manufacture. A key point is a stage
  beyond which either the product requires an expensive operation or it may not be capable of rework.
• Inspection at a key point segregate and thus avoid unnecessary further expenditure on poor end
  substandard parts, which are likely to be rejected finally.

(d) Final inspection:
• Final inspection of the product may check its appearance and performance.
• Many destructive and non-destructive and test methods such as tensile, fatigue, impact testing, etc.,
  and ultrasonic inspection, x-ray, radiography, etc., respectively, are available for final inspection of the
  products manufactured.
• Final inspection is a centralized inspection and it makes use of special equipments.

Inspection Of Incoming Materials, Raw Or Received Materials
• Incoming raw materials are inspected in order to:
(i) eliminate those materials which do not meet specifications and are likely to cause trouble during
    processing; and to
(ii) Evaluate vendor’s quality and ability to supply acceptable materials.
• Raw materials involving in high transportation charges are checked by the buyers at vendor’s end
  whereas others are inspected as soon as received at purchaser’s plant.
• Inspection of raw materials may involve a visual check up only, a dimensional check, a test of
  physical properties and chemical compositions, etc,.
• Raw materials depending upon their characteristic and use many require a sampling inspection or
  100% inspection.
• After inspection, the right quality parts are sent either to stock room or assembly lines.

Inprocess Inspection
• An effective in process inspection eliminates,
(i) Defects so that the subsequent operation is not badly affected;
(ii) A defects which may be concealed in the final product (e.g. after painting, etc.);
(iii) Extra work from being performed on rejectable materials.

• In process inspection is carried out by;
(a) Workers doing the job.
(b) Inspectors from the inspection department

• Inprocess inspection may check,
(a) A first few parts of the new machine set up, or a new operation.
(b) A part before it move for the next operation
(c) A part before it goes for an expensive operation.
(d) A part after a series of manufacturing operations.
(e) Parts before sub- assembly or final assembly
(f) A part before it is being sent for plating or painting.
(g) A part before it moves to the next department.

• For inprocess inspection, the inspectors are stationed are specific stages in the manufacturing
• Automatic sizing and gauging equipments which can check a large numbers of dimensions   
  simultaneously are sometimes built in the processing machinery. A feedback system automatically
  resets the machine to correct the error measured by the automatic gauging equipments.

Inspection Of Finished Goods

• An unthrough inspection of finished and final goods may permit faulty products to be dispatched to the
  customer, because it is the last chance of detecting imperfection in the products manufactured.
• The finished goods inspection is

(a) Visual to ascertain appearance and dimensions; and
(b) Functional to ensure that the product will work to specifications
