Cleaning of Machined Components

Cleaning of Machined Components
14th November 2014, BIEC, Bangalore

Parts cleaning, like most metalworking processes, are experiencing ever tightening specifications. Owing to the constantly increasing requirements in terms of efficiency, quality and environmental protection the cleaning of industrial parts has become absolutely essential in modern manufacturing processes. It is highly critical especially in case of automotive components, aerospace and medical implants.

However, Parts cleaning is often the most ignored area in the production lines. Cleaning is commonly considered as non-value adding process; without evaluating the consequences of ignoring component cleaning. A successful cleaning process requires careful selection of both the cleaning chemistry and equipment. Cleaning process is influenced by various factors viz. manufacturing process, cleaning media, surrounding conditions, work‐piece quality, parts handling, machine technology, testing process (Millipore test), etc.

Keeping this in view, the Indian Machine Tool Manufacturers' Association (IMTMA) organized a one day seminar on “Cleaning of Machined Components” on 14 November 2014 at Bangalore.

The seminar was conducted by industry experts from Crest Ultrasonics India., Durr Eco Clean, Quaker Chemical India and SKF India.

The participants for the seminar were from companies such as Bajaj Auto, Carclo Technical Plastics, Kusalava International, Optomech Engineers, SAI India, Sundaram Clayton, TMI Rollon Engineering, TVS Motor, and Wichitra Auto.

Design of Pressure Die Casting Dies

Design of Pressure Die Casting Dies
9 – 10 December 2014, IMTMA Technology Centre, Bangalore

Die Casting is a versatile process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds, called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. The Pressure Die Casting process is the shortest route to convert metal to components of light alloys. Pressure Die Casting has replaced many cast iron parts in appliances, automotive and aerospace fields. By careful design, it is possible to get strong, stiff and yet light weight constructions with Pressure Die Casting. Parts can be sharply defined, with smooth or textured surfaces and are suitable for a wide variety of attractive and serviceable finishes.

Die castings are among the highest volume, mass-produced items manufactured by the metalworking industry, and they can be found in thousands of consumer, commercial and industrial products, ranging from automobiles to toys. However, to achieve maximum benefits from this process, proper Die design assumes paramount importance.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a two day training programme on Design of Pressure Die Casting Dies on 9 - 10 December 2014 at IMTMA Technology Centre in Bangalore.

The training programme focused on Pressure Die Casting Process, Die Steels & Die Casting Alloys, Feed System & Cooling System, PQ2 Diagram, Design of Die Casting Dies, Rapid Cost Estimation of Dies, Defects & Remedies.

The training programme saw participation by 10 delegates representing companies like Esko Die Casting, Om Sai Moulds & Plastics, Pacoline Industries, Production Aids & Consultants, Smexports, Systemantics India, and Unique Auto Assemblies (ICH). The programme was conducted by industry experts from Nettur Technical Training Foundation, Bangalore.

Defect Analysis & Trouble Shooting of Injection Moulded Components

Defect Analysis & Trouble Shooting of Injection Moulded Components
18th - 19th November 2014, BIEC, Bangalore

We are said to be living in an era of 'plastics' since 1974, as the world consumption of plastics from that year onwards exceeded that of steel by volumes! From household appliances to airplanes, from tooth brushes to telephones, from computers to cars, everything seems to be made out of plastics these days. The reasons are not far to seek. Injection moulded plastic parts offer unbeatable combination of light weight construction, flexibility, toughness, chemical resistance, long-term performance and cost effectiveness.


The defects in injection moulding may be caused by poor part design, wrong selection of material, poor injection mould design, poor manufacture of mould, non-optimum process parameters and wrong matching of mould with machine amongst others. Knowledge of ways and means of overcoming these defects is necessary to obtain world class injection mouldings.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a two-days programme on Defect Analysis & Trouble shooting of Injection moulded in Bangalore.

The event saw participation by 18 delegates representing nine companies predominantly from South India. The interactive sessions on the topic was also well absorbed by the delegates, who appreciated IMTMA for conducting programmes on topics such as these, which would help participants to implement various ideas in their day-to-day activities.

Hands-on Training in Dimensional Metrology

Hands-on Training in Dimensional Metrology
3 – 5 December 2014, IMTMA Technology Centre, Bangalore

Dimensional Inspection assesses the geometric characteristics of parts and products to assure their compliance with design requirements and verifies the accuracy of product features that can decide reliability and functionality of the product / production. Engineers and technicians involved in manufacturing processes and measurement applications need to have sound knowledge in proper selection, application, and care of typical measurement systems. Best practices in dimensional metrology need to be followed for obtaining reliable measurements.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a three days Hands-on Training in Dimensional Metrology from 3-5 December 2014 at IMTMA Technology Centre, Bangalore. The objective of the programme was to enhance the level of competency in usage of precision hand tools, bench top measuring instruments, attribute gauges and other advanced measuring systems including surface roughness tester, roundness tester and CMM.

The programme mainly focused on the fundamentals of precision measurement, types of data, uncertainties involved in measurement, laws of metrology, references and standard gauges, proper use and application of basic ‘hand’ tools, types, selection and proper use of attributable gauges, pneumatic gauges, common applications of pneumatic gauges, introduction to advanced measurement systems, and need of calibration of measuring instruments and gauges. It was conducted by a faculty team from IMTMA Technology Centre and industry experts from Baker India.

The hands-on training was attended by 20 participants from companies such as Ace Designers, Anand Automotive, Aruna Alloy Steels, Bill Forge, Defence Metallurgical Research Laboratory, Hindustan Aeronautics, Liners India, Microprecision Solutions, New Die Casting, SMC Medical Manufacturing, Spicer India, Titan Company, and Wipro Infrastructure Engineering.
