Revolutionizing Manufacturing with APG-Metal Injection Molding: A Comprehensive Guide

Metal injection molding (MIM) is a metalworking process that involves the manufacturing of complex metal parts using metal powders and injection molding technologies. This process is widely used across various industries, including aerospace, automotive, consumer products, and medical devices.

However, one of the challenges with MIM is that it limits the size of parts that can be produced due to the limitations of the injection molding technologies. That's where advanced powder metallurgy techniques, such as APG-metal injection molding (APG-MIM), come in.

APG-MIM is an advanced manufacturing process that combines the advantages of APG (advanced powder metallurgy) and MIM technologies to produce larger, more complex parts with high accuracy and precision. In APG-MIM, the metal powders are mixed with a binder material and injected into a mold cavity. The binder material is then removed by sintering, which fuses the metal powders together to form the final part.

The advantages of APG-MIM are many. For starters, it allows for the production of parts with intricate geometries that are not possible with traditional MIM techniques. APG-MIM also reduces the need for secondary machining operations, thus increasing the efficiency of the manufacturing process. In addition, this process is highly scalable and can be used to produce both small and large production runs.

APG-MIM has numerous applications across various industries. For instance, in the aerospace industry, APG-MIM is used to manufacture parts for engines, brake systems, and landing gear. In the medical device industry, this technique is used to produce surgical instruments, dental implants, and orthopedic devices. In the automotive industry, APG-MIM is used to produce parts for engines, transmissions, and fuel systems.

In conclusion, APG-MIM is a game-changer in the world of metalworking. With its ability to produce complex, highly accurate parts at a large scale, it is no surprise that its applications span across numerous industries. As the demand for high-performance, reliable, and cost-effective parts continues to grow, APG-MIM is sure to play a crucial role in shaping the future of manufacturing.

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.
