Revolutionizing the Manufacturing Industry: The Emergence of Metal Injection Molding in India

The manufacturing industry is constantly evolving, with new technologies and processes making their way into the market. One of the latest advancements is metal injection molding (MIM), which has opened doors for more cost-effective and efficient ways to produce complex metal parts. In India, MIM has been gaining momentum in recent years, with several companies leading the way in its implementation and utilization.

MIM is a manufacturing process that involves mixing fine metal powders with binders to create a feedstock that can be molded into intricate shapes using injection molding. After molding, the part is then subjected to a debinding process to remove the binder and then undergoes a sintering process to densify the part to its final shape. The biggest advantage of MIM is that it can be used to create complex parts with high levels of accuracy and consistency.

One of the biggest players in the MIM market in India is Indo-MIM, which has been at the forefront of the industry for over two decades. The company has developed a strong reputation for producing high-quality MIM parts that can be used in a variety of industries, including automotive, aerospace, and medical. Indo-MIM has a fully-integrated manufacturing facility in Bangalore that utilizes the latest MIM technology to produce millions of parts per month.

Another notable player in the Indian MIM market is Flexan India, a company that specializes in producing MIM parts for the medical industry. Flexan India has invested heavily in research and development to create innovative MIM products that meet the specific needs of the medical industry, including implantable parts and surgical instruments.

Other companies that have embraced MIM in India include Ace Micromatic Group, which produces MIM parts for the automotive industry, and Dynacast India, which specializes in MIM parts for the electronics industry.

However, despite its many benefits, MIM is still relatively unknown in India and faces challenges in terms of raising awareness and building a supply chain. The process requires highly specialized equipment and expertise, which can be a barrier to entry for small businesses. Additionally, the cost of MIM production can be higher than traditional manufacturing processes, which can make it less appealing to certain industries.

Despite these challenges, the potential for MIM in India is vast, especially in the automotive and medical industries. As the manufacturing industry continues to evolve and demand for more complex parts increases, it is likely that MIM will become an even more important technology in India's manufacturing landscape.

In conclusion, the emergence of metal injection molding in India is a promising development in the country's manufacturing industry. With companies like Indo-MIM and Flexan India at the forefront of MIM technology, India is becoming a major player in the global MIM market. While challenges remain, MIM has the potential to revolutionize the way complex metal parts are produced, paving the way for a more cost-effective and efficient manufacturing industry in India.

Our rapid injection molding Application

Sigma Technik Limited's rapid injection molding service injects molten plastic materials into molds using injection molding machines and molds, and cools and solidifies them over a certain period of time, ultimately forming the required plastic parts. This manufacturing process is usually suitable for producing small and medium-sized plastic parts, which can obtain high-quality and precise parts in a short period of time.

Plastic Injection Molding

Injection molding is a common manufacturing process to produce low volume to large volumes of parts typically made out of plastic. The process involves injecting molten material into a mold and letting it cool to a solid-state.

Liquid Silicone Rubber Molding

Liquid Silicone Rubber is known as LSR, which is a process used to produce parts made from silicone rubber, widely used create products such as medical devices, automotive parts, baby care products, and many others.

2K Injection molding

2K injection molding is a manufacturing process in which two different types of plastic materials are molded together in a single operation to create a single homogeneous component. This process allows for efficient and cost-effective production of high-quality parts that can perform unique functions.

Overmolding and Insert Molding

Overmolding / Insert molding combines two or more materials into a single part, one of the material is usually soft and flexible, or metal. The purpose of overmolding/insert molding is to add functionality, improve grip, provide protection, or enhance aesthetics.

Rapid Injection Molding FAQs

Burrs appear on the surface of the product, which affects its aesthetics and safety. The solution can be to adjust the parameters of the injection molding machine, such as temperature, pressure, speed, etc., or to perform post-processing, such as polishing, sandblasting, etc.

The warping deformation of the product is usually caused by unstable parameters such as temperature and pressure of the injection molding machine, or improper mold design. The solution can be to adjust parameters such as temperature and pressure, or to redesign the mold.

The occurrence of bubbles inside the product may be due to the high temperature of the injection molding machine and the high moisture content of the material. The solution can be to reduce the temperature of the injection molding machine, adjust the water content of the material, increase the pressure of the injection molding machine, etc.

The product size deviation is too large, which may be caused by material thermal expansion, mold deformation and other reasons. The solution can be to adjust parameters and optimize mold design based on material characteristics.
