Metal Injection Molding: A Comprehensive Analysis of the Industry's Growth, Market Trends, and Future Outlook

In this blog post, we will explore the metal injection molding (MIM) industry in detail. We will provide an overview of MIM and explain the process behind it. We will also look at the current state of the industry and analyze the growth and market trends. Finally, we will provide an outlook on the future of the MIM industry.

Overview of MIM

Metal Injection Molding, or MIM, is a process used in the manufacturing industry to produce small, intricate, and complex metal parts. It is a form of powder metallurgy that combines the benefits of plastic injection molding and sintering of metal materials.

The MIM process involves several steps. First, metal powder is mixed with a thermoplastic binder to form a feedstock. The feedstock is then molded using injection molding equipment to form the desired shape. After the part is molded, it is then subjected to heat to remove the binder and sinter the metal particles together to form a solid metal part.

Current State of the MIM Industry

According to a report by Research and Markets, the global metal injection molding market was valued at $2.5 billion in 2020. The market is expected to grow at a CAGR of 7.8% from 2021 to 2028, reaching a value of $4.6 billion by 2028. The growth of the market can be attributed to several factors, including the increased demand for small and complex metal parts across various industries such as healthcare, automotive, aerospace, and defense.

The healthcare industry is one of the major end-user industries for MIM, accounting for 26% of the MIM market share in 2020. This is due to the increasing demand for medical implants and devices that require small, intricate parts with high precision and performance.

Market Trends

One of the major trends in the MIM industry is the increasing adoption of 3D printing technology. 3D printing has been used to make molds for injection molding, reducing the cost and time required to produce molds. The adoption of 3D printing has also enabled companies to produce customized parts on demand, providing a competitive advantage.

Another trend in the MIM industry is the development of new materials and alloys. The use of new materials and alloys has expanded the range of parts that can be produced using MIM. For example, the use of titanium and zirconia has enabled the production of parts for the medical and dental industries.

Future Outlook for the MIM Industry

The future of the MIM industry looks bright. The increasing demand for small and complex metal parts across various industries, coupled with technological advancements, is expected to drive the growth of the MIM market.

The use of 3D printing technology is expected to play a significant role in the future of the MIM industry. The adoption of 3D printing can reduce the cost and time required to produce molds, making the production process more efficient.

The development of new materials and alloys is also expected to drive the growth of the MIM market. The use of new materials and alloys can expand the range of parts that can be produced using MIM, providing new opportunities for companies in the industry.

In conclusion, the metal injection molding industry is poised for continued growth and expansion. The adoption of 3D printing technology, the development of new materials and alloys, and increasing demand from various end-user industries are expected to drive the growth of the MIM market in the coming years.

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.
