EMI/EMC Calibration

EMI/EMC determines whether a device or system will create an electromagnetic disturbance and interfere with the operations of other devices. When you have properly calibrated testing equipment, you are assured of accurate measurements related to the electromagnetic compatibility of a product or system. The equipment that measures or generates electromagnetic fields must be calibrated periodically to verify proper operations.

A smart way of managing productive resources

A transformative change significantly alters the profile, capabilities, contours and culture of an organization. Total Productive Maintenance (TPM) is a well-established way of managing production resources for meeting ever-rising standards of productivity, quality and reliability.

Towards Digitally Aided Fabrication

It is estimated that the cycle time of the cutting process stands reduced by a hefty 75%.

Godrej Bambusa Bikes

In 2012, Mr. Vijay Crishna visited Antarctica with British explorer, Sir Robert Swan, to witness climate change, first-hand. During the visit, their group welcomed two young Dutch men who had spent the previous 15 months cycling 16,000 kms from Deadhorse, Alaska to Ushuaia, riding bamboo-framed bikes! Mr. Crishna was very impressed with the bikes, and on his return, he asked the Lawkim team to develop such bikes.

“The essence of strategy is also choosing what not to do!”

Talk of growth, and what comes naturally to mind is: widening of the product offerings, adding new categories, expanding into newer markets, forming strategic alliances and so on.

Sailing the Uncharted Seas

The ‘can-do’ attitude and deep confidence in the capabilities of the team are essential to execute large projects having complex developmental work.
