Wholesale Metal Injection Molding: The Future of Precision Parts Manufacturing

Metal Injection Molding (MIM) has been a revolutionizing technology in the manufacturing industry, providing an advanced level of precision and efficiency in part production. The industry is expected to grow significantly in the coming years, with projections suggesting a CAGR of 11.5% between 2021-2026, as per a report by Mordor Intelligence.

With the rising demand for high-precision metal parts across various industries, the wholesale metal injection molding process brings a range of benefits for companies looking to streamline their production and improve quality. In this blog, we will explore the benefits of wholesale metal injection molding for precision parts manufacturing.

1. Improved Precision

MIM facilitates the formation of small, intricate, and complex parts with high accuracy and consistency. This process integrates the benefits of traditional injection molding and powder metallurgy. The formability of the metal powders allows the creation of intricate geometries ranging from 0.1g to 250g. This results in an improved dimension accuracy and efficient mass production of high-precision parts.

2. Cost-Effective

In comparison to traditional machining and casting methods, metal injection molding reduces material waste and manufacturing costs significantly. The process saves up to 50% of the cost incurred in the production of intricate metal parts. MIM uses a significant amount of metal powder, making it a cheaper option for mass production of parts for industries such as medical, aerospace, and automotive.

3. Versatility in Choice of Materials

MIM enables manufacturers to use a range of materials including stainless steel, low-alloy steel, and tungsten alloys. It opens up the possibility of manufacturing intricate parts, including those with complex shapes and geometries, which cannot be produced by other traditional manufacturing methods.

4. High Strength & Durability

Metal injection molding incorporates metal powders which are sintered at high temperatures resulting in high strength and durable parts. The final product has properties that are comparable to wrought materials and can withstand harsh environmental conditions, which makes it an attractive option in the aerospace, automotive, and medical industries.

5. Streamlined Production Process

MIM is a streamlined and automated process that results in efficient mass production. The entire process involves four stages - mixing, injection molding, de-binding, and sintering. The process minimizes the possibility of error, ensuring that each part produced is of the highest quality.

In conclusion, wholesale metal injection molding is an advanced process that offers a range of advantages in the production of high-precision parts. The process provides excellent accuracy and consistency, reducing manufacturing costs, and provides a versatile range of materials and shapes for manufacturers to choose from. With the projected growth of the MIM industry, it is an exciting time for the manufacturing industry to embrace this technology and streamline their production processes.

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.
