Metal Injection Molding

AMT worker operates an sintering furnace in a manufacturing facility, loading metal parts for heat treatment.

Metal Injection Molding

Metal Injection Molding (MIM) combines the precision of injection molding with powdered metal to produce highly complex metal components with exceptional mechanical properties. With deep expertise in Our MIM Process Technology, we leverage advanced manufacturing processes to provide design freedom and material flexibility.

Our team works closely with you from the initial design stage through to final production, efficiently addressing manufacturing challenges and delivering innovative, cost-effective solutions.

Our Metal Injection Molding Process

01. Mixing

Metal/ceramic power is mixed with polymer binder to form the feedstock.

02. Injection

The feedstock is molded to form the desired geometry known as green part.

03. Debinding

The polymer binder is removed from the green part by a debinding process to form the brown part.

04. Sintering

During sintering, the brown part shrinks and densifies into a net-shape solid component.

Metal Injection Molding Materials

The MIM process starts with feedstock compounding, where selected metals are mixed to create a customized feedstock. Material selection depends on the specific end-use requirements of your part, whether for high strength, biocompatibility, or corrosion resistance. Our MIM technology supports a wide range of industry-standard materials in both ferrous and non-ferrous categories.

Ferrous Alloy

Ferrous alloys are iron-based metals, including carbon steels, stainless steels, nickel-free stainless steels, low alloy steels, soft magnetic alloys, and low thermal expansion alloys. These materials are selected based on their strength and durability, while properties such as corrosion resistance and magnetism vary depending on the specific alloy.

Non-Ferrous Alloy

Non-ferrous alloys, including superalloys (Inconel), F75, MP35N, Nimonic 90, Tungsten-Heavy Alloy (WHA), Tungsten-Copper (WCu), and Copper (Cu), offer high corrosion resistance, superior conductivity, and excellent mechanical properties. These materials are essential for high performance applications requiring strength, durability, and specialized performance.

In Tungsten-Heavy Alloy (WHA), the composition can be selected to specific applications:

92.5% Tungsten + 2.5% Iron + 5% Nickel – High-density alloy with exceptional mechanical strength, corrosion resistance, and thermal stability.

90% Tungsten + 4% Iron + 6% Nickel – Balanced durability, wear resistance, and impact absorption.
