Work Experience

Manager Application Engineering 
Since 1995 to 2004
Company Profile: Leading manufacturer of plastics molding machines
Job Profile:
New Application development in the form of complete viable economic project by integration of mould, machine, material and processing techniques. Developed markets
for chair, cable ties, household as well as engineering applications.
Handled retrofitment business from sales, design, and manufacturing to execution stage
for any injection machines of domestic as well as international make.
Design of injection unit side of injection molding machine and development of screw/barrel, die head assembly for blow molding machines.
Handled service function for polymer processing for the organization.
Conceptualization of new machine models and control logic software development for all the machines.
Trouble shooting of processing problems of processors of Injection and Extrusion blow moulding.
Specification determination of Injection and Extrusion blow moulding machines to suit requirements of the application.
R and D interface with customers for development of new models of Blow molding machines and injection molding machines through conceptualization of SPM for
specialized products.

Design of screw/barrel systems:
Numerous new extrusion screws have been designed using simulation software (SPAR – Tadmore- Klein model) successfully for higher output and lower energy consumption for
various Injection moulding machines in the diameter range of 34 mm to 150 mm diameter.
The designs have been highly successful in improving the productivity of the machines by way of reduced use of color master batches and improved output and hence lesser
cycle time.
The various types of designs from conventional to barrier types with several types of mixing zones have been standardized. Special designs like grooved barrel and barrier as well as wave type screws have been made and implemented.
Other than universal screws, material specific screws have been designed and standardised for various models of machines. Some of the material specific series
introduced are SPVC, RPVC, Polyolefins, Polycorbonate (flame retardant grades) and PET.

Trouble shooter of processing problems:
Solutions for processing problems through design modifications of hydraulic circuits and logic modification of software and mechanical system improvements.
Failure analysis of mechanical components and solutions through design modifications.
Solutions through integration of mould, machine and material specifications.
