Our Infrastructure

Built for Precision
at Scale

JN Metal is customer-centric. We have invested in different essential facilities to achieve the goal of speedy product development of even the most complex castings. Utilizing the best tools in the industry like casting simulation along with a deep knowledge bank, our seasoned professionals evaluate the filling and solidification process to ensure castings are produced defect-free from the initial stage.

Tool design is done in-house using Unigraphics and Delcam is used to generate CNC code from 3D data. Tools are manufactured using our four CNC Vertical Machining Centers of different sizes. Our Pattern Shop ensures all tooling is well maintained throughout the life of the tool.

Product Development

JN Metal utilises the best tools in the industry — casting simulation software along with an extensive knowledge bank. Our seasoned and talented professionals evaluate the filling and solidification process of the metal to ensure castings are produced defect-free right from the initial stage.

Tool design is done in-house by our engineering team using Unigraphics, while Delcam is used to generate CNC code from 3D data. Tools are manufactured using our four CNC Vertical Machining Centers of different sizes — ensuring quick, reliable, and steadfast development of new castings.

Centrifugal Casting

Centrifugal casting (rotocasting) is a casting technique typically used to cast thin-walled cylinders. It is noted for the high quality of results attainable — particularly for precise control of metallurgy and crystal structure.

Unlike most other casting techniques, centrifugal casting is chiefly used to manufacture stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use. This is ideal for producing bushes, liners, and bearings with superior mechanical properties.

Investment Casting

Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mould. A wax pattern is made in the exact shape of the item to be cast. This pattern is then coated with a refractory ceramic material.

Once the ceramic material is hardened, it is inverted and heated until the wax melts and drains out. The hardened ceramic shell becomes an expendable investment mould. Molten metal is poured into the mould, left to cool, and the metal casting is removed from the spent mould — delivering exceptional dimensional accuracy and surface finish.

Sand Casting

A precise mould is quintessential for any high-quality casting. Our moulding process for producing moulds results in castings with perfect dimensional accuracy and superior finish. We use Green Sand Hand Moulding and Shell Sand Stag Moulding in our foundry.

Sand casting allows us to produce a wide range of ferrous and non-ferrous castings from small to large components, with reliable dimensional repeatability across production runs and excellent cost-effectiveness for medium to high volumes.
