Latest Trends in PDC Dies & Plastic Mould Manufacturing


Changing customer expectations and rapid model changes requires a fast turnaround in the manufacture of Dies & Moulds. Presently, production demands require the ability to react to frequent product changes, shorter production runs, lower inventory levels and higher productivity.

To meet these challenges a host of new technologies have evolved over the years. Apart from the conventional technologies like Die sinking & Wire EDMs the new generation manufacturing extensively uses hard machining and complex profiling on multi axis machining centres to completely finish the die and mould with little need for manual finishing and correction. Supporting these machining methods are new developments in design analysis, inspection techniques and complex programming systems.



Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organised a 2 day programme on Latest trends in PDC Dies & Plastic Mould Manufacturing on 24 - 25 February 2016 at IMTMA Technology Centre in Pune.

The programme primarily focused on :

  • Relation between "First Time Right Mould Design" and Reduction in mold manufacturing lead time.
  • Advanced Materials for Die and Moulds.
  • Failure modes of moulds / dies- causes and remedies.
  • PDC Die design and maintenance.
  • Using simulation and analysis for optimising mould design.
  • Impact of surface coating on mould / die performance.
  • High speed machining of Dies & Moulds.


The training programme was conducted by industry experts from Autodesk India, Bohler Uddeholm India, DMG Mori Seiki India Machines & Services, Godrej & Boyce Manufacturing, Oerlikon Balzers Coating India and NTTF. Mr. Avinash Khare, Head, IMTMA Technology Centre, Pune was also present.

Design of Workholding & Fixturing


Design of workholding & fixturing is key to effective utilization of machine tools. Basics of fixture design if not implemented correctly results in poor productivity & quality problems. Set-up time and cycle time reduction, increased accuracy on components, deskilling the job setting operation are the obvious advantages of a good fixture. Competence in workholding & fixturing differentiates excellent organizations.

 
 


Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day seminar on Design of Workholding & Fixturing on 12 - 13 January 2016 at IMTMA Technology Centre in Pune.

 

The programme primarily focused on :

  • Various types of Workholding fixtures
  • Key factors & Technical features of workholding fixtures
  • Design of basic elements of a fixtures
  • Elements for Hydraulic / Pneumatic fixtures
  • Design consideration for Manual, Hydraulic & Pneumatic fixtures
  • Safety features & cost control while designing a fixture & its elements
  • Trouble shooting of the fixtures to achieve desired quality of component
  • Group exercises in concept development of fixtures


The seminar was conducted by Mr. S.K. Gupta, Consultant and Mr. Gautam Doshi, Advisor, IMTMA. Delegates from Bajaj Auto, Brakes India, Gala Precision Engineering, Harita Seating Systems, Hyundai Construction Equipment India, Mahindra & Mahindra, Mahindra Gears & Transmission, Parth Equipment, Parth Industries, Reliable Autotech, RINGSPANN Power Transmission, Spicer India, and ThyssenKrupp Engine Components India, attended the seminar.

Feedback

"The two day programme was a good learning experience and I hope to build on this. There were many take-away from the same."

Defects Analysis of Paint & Powder Coating Applications

In today's manufacturing scenario, where shortage of raw material, power & increasing pressure to reduce costs are the order of the day, ‘Painting / Coating application’ is possibly the most troubled issue. While we are nearly at par with global standards in metal working, we definitely lack in finishing and Powder Coating Applications operations. The stark difference is visible when it comes to exporting our goods. Lack of knowledge in Defect Analysis especially in painting / powder coating and Buck passing between paint or powder suppliers vs equipment suppliers lead to high rework and rejection rates.

 

Keeping this in view, Indian Machine Tool Manufacturers' Association organized a 2 day seminar on Defects Analysis of Paint & Powder Coating Applications on 14 - 15 October 2015 at Gurgaon.

The programme focused on Paint Film Defects, Root Causes and Remedies, Basics of Paints / Coatings, Types & Importance of Pretreatment before Paint / Coatings applications & their types, Basics of Paint / Coatings Spray Applications, Paint Spray Techniques, Paint Application Techniques, How to improve the transfer efficiency, Quality Control / Quality Assurance, etc.

The programme was conducted by Mr. Meghan Manjrekar, Industry expert in Surface Coating & Application Technology. Delegates from Avon Coatings, FCA Engineering India, Honda Motorcycle & Scooter India, Jash Engineering, KDDL, Maruti Suzuki, and Roots Multiclean, attended the seminar.

Challenges and Solutions in Thread Cutting Operations

Challenges and Solutions in Thread Cutting Operations

One of the most important but less understood machining processes is Threads and Thread Machining. Most components produced today, whether in the auto sector, process control, or equipment manufacturing contain at least one form of thread. Hence thorough understanding of the basics and usage of threads and thread cutting tools is of primary importance, especially so with internal threads, where the operation is constrained.

Threading applications today call for materials with high strength to weight ratios which are more often than not, difficult to machine. These impose high demands on thread cutting tools and tool holding and performance limits are stretched continuously. Therefore it becomes imperative that all aspects of threading, be it thread cutting, thread forming, tool holding or thread gauging, be explored fully to realize the full potential of the tooling available today.

 

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) had organized a one day programme on Challenges and Solutions in Thread Cutting Operations on 11 December 2015 at IMTMA Technology Centre in Pune.

The training programme focused on :

  • Basics of threads
  • Overview of thread cutting methods - Thread rolling, Thread cutting, Tapping, Threadmilling, Relative advantages and limitations
  • Tap geometries, Cold Forming Taps
  • Basics of Tapping
  • Basics of Thread Milling. Tap Holders, Rigid Tapping Care of Tap Holders
  • High speed Tapping for mass production
  • Demo of Tapping and Thread Milling in CNC Machining centre and cycle time analysis
  • Observation of Chips produced. Demo of Softsynchro to measure Synchronising errors
  • Check list for tap trials
  • Use of thread gauges; Do's and Don'ts; Calibration of gauges; care and maintenance tips

The training programme was conducted by Mr. K.N. Heblekar, EMUGE India, Pune.

Delegates from Benteler Automotive India, Bajaj Auto, Fiat India Automobiles, and Jayahind Industries attended the training programme.
