  • From initial stages of tooling design, to completion of production tooling, the in-house CAD/CAM design & manufacturing facilities provide the tools required for quick development of new castings.
  • Our Pattern Shop also ensures that all tooling is well maintained and serviced to ensure maximum life of tooling.

Moulding Shop

Kunkel Wagner NelcastAny high quality casting begins with a high-quality mould. This concept is clearly embodied in our investments in technology for producing moulds which result in castings with exceptional dimensional accuracy & superior surface finish.

Our state-of-the-art High Pressure Moulding Line at Ponneri is one of the largest in India and first of its kind in Asia. The Kunkel Wagner DFM-R- High Pressure Moulding Machine with AIRPRESSplus 2000 Technology and active multi piston squeeze head controlled by a Siemens S7/400 PLC to ensure perfect repeatability of all moulding parameters.

In order to optimize the working of this line, the Company has also installed a state-of-the-art Automatic Sand Conditioning Plant which incorporates a KW-ASR series sand cooler, KW-WM series high intensity sand mixer with automated additions of additives and automatic moisture control system ensures consistent quality of prepared sand. An ABP OCC-50 PressPour system delivers the metal to each of the perfectly produced moulds.

The most recent addition to the Nelcast stable is the yet another High Pressure Moulding Line, the DISA Flex 70HS with DoubleBlow and Flexipad Squeeze compaction technology. This line is complemented by a DISA SKA fluidized bed sand cooler, a DISA TM intensive sand mixer with automated additions of additives and a Sand Multi-Controller to precisely control sand parameters. An Inductotherm Tundish Pouring system equipped with Visipour ensuring perfect control over the metal pouring process.

The High Pressure Moulding Line is well complemented by our DISA Arpa series simultaneous Jolt + Squeeze Moulding Machines:

  • DISA ARPA - 450 (5 Nos.)
  • DISA ARPA - 900 (4 Nos.)
  • DISA ARPA - 1300 (1 No.)

Due to the wide range of moulding machines that Nelcast employs, we are able to service a very diverse product range and can offer customers the most economical solution for their specific product.
