UK Foundry Experts Help Pioneering Group Create India's First Titanium Casting Facility
Castings Technology International (Cti) has helped pioneering Indian foundry group, PTC Industries, launch the Asian subcontinent’s first ever Titanium casting facility.
PTC has created the new facility at
its Advanced Manufacturing Technology Centre in Lucknow in response to demand from customers at home and abroad and with backing from the Indian government’s ‘Make in India’ campaign. The development is the latest fruits of a long-standing relationship with Cti, the
leading European centre of excellence providing independent R&D, technical support and consultancy services to the castings and metal related industries. PTC’s managing director, Sachin
Agarwal, said: “Our company has been growing at an extraordinary pace and is determined to meet the future needs of a rapidly evolving global industry as well as the growing Indian economy. “With Cti’s help we are building on our existing technological strengths and have been able to rapidly adapt and respond to the demand for the Titanium castings which our clients require.” Cti,
based on the Advanced
Quality Products. Lasting Performance.
Manufacturing Park at Catcliffe, near Sheffield, helped PTC design and equip its Titanium facility, which will produce high integrity castings for safety critical applications, including valves for the US and European oil and gas sector. Cti foundry process consultant

James Collins, who recently returned from assisting with PTC’s first Titanium cast, said: “We have been delighted to be able to use our expertise in designing new foundries, Titanium casting and providing on-site support to help a technically advanced client like PTC to add an important new capability.” Cti advised on the acquisition and installation of PTC’s consumable electrode VAR Titanium melting furnace, which has the capacity to deliver just over 60kg, both statically and centrifugally. The organisation helped PTC
overcome the challenge of converting the furnace, originally designed to run on a US mains supply, to Indian specifications with the capability to be powered by a generator – something which the German furnace builders had
thought impossible. Cti also advised on pre and post-
cast operations, provided training and commissioning services, made sample parts and carried out trials of Hot Isostatic Pressing (HIPping) equipment, which is essential for processing Titanium castings.
As a result, PTC has not only
become the first Indian foundry to make a Titanium casting, it also has India’s sole HIPping facility, with the capability to process castings up to 1.2 metres in diameter, far larger than those it can currently make using its furnace As much as half the cost of a
Titanium casting can be in the finishing, so PTC could acquire larger castings for the Indian market from suppliers such as Cti and add significant value to them in country.
PTC is no stranger to achieving
‘firsts.’ The company became the first
Indian-owned investment casting foundry in the country, when it was established in 1963 and later became the first company in Asia to produce a
casting using Cti’s
technology. The Replicast® process involves
dipping a sacrificial pattern, which can be 3D printed, made from CNC- machined or injection moulded foam, or wax into a tank full of a special slurry to create a ceramic shell, which is then fired to create a mould for the casting. PTC is now the exclusive Indian licensee of the process, which not only produces castings with an excellent surface finish, but also combats potential quality issues caused by humidity during the Indian summer leading to increased hydrogen absorption.
