MIM Material Selection Guide: 316L vs 17-4PH vs Low-Alloy Steels

MIM material selection balances corrosion resistance, strength, magnetism, and cost. The three main families are 316L stainless steel (corrosion-resistant, non-magnetic), 17-4PH stainless steel (high strength, magnetic), and low-alloy steels (cost-ef...

MIM vs Metal 3D Printing: Which Process Fits Your Part?

Metal injection molding (MIM) and metal 3D printing both form complex metal parts, but MIM suits medium-to-high volumes (>10,000 parts/year) with tight tolerances and near-full density, while metal 3D printing wins for prototypes, low volumes and geo...

MIM Design Rules: 10 DFM Guidelines for Metal Injection Molding Parts

Metal injection molding (MIM) DFM guidelines cover wall thickness (0.5–5 mm, uniform), draft angles (0.5–2° per side), rib/boss thickness (50–70% of wall), hole sizing (0.3–0.5 mm min), tolerances (±0.3%), gate location, and sintering shrinkage (15–2...

MIM vs Die Casting: Which Process Suits Complex Metal Parts?

MIM and die casting are both molding processes for metal parts, but MIM molds a metal-powder feedstock that is debound and sintered, suiting small, complex, high-melting parts, while die casting forces molten low-melting alloys like aluminium and zin...

MIM for Power Tools: Precision Gears, Pawls and Structural Components

Metal injection molding (MIM) produces complex, near-net-shape steel parts for power tools—gears, pawls, hammers, brackets and chuck components—with wrought-like properties at lower unit cost. It suits high-volume runs (tens of thousands per year), u...

Surface Treatment and Finishing Options for Sintered Metal Components

Finishing turns as-sintered MIM parts (matte, ~Ra 1.6 µm) into finished products by improving appearance, corrosion resistance, wear life and dimensional accuracy. Options include mechanical finishing (tumbling, blasting, grinding, polishing, CNC), h...

Differences Between MIM and Traditional Powder Metallurgy (PM): How to Choose Between Pressing-Sintering and Injection Molding

MIM (metal powder injection molding) and traditional PM (pressing-sintering) are distinct powder metallurgy routes: PM uses uniaxial die pressing plus sintering for simple 2.5D parts at 90%–95% density, while MIM uses feedstock injection, debinding, ...

Common MIM Defects and Solutions: How to Prevent Short Shots, Deformation, Cracking, and Porosity

MIM defects—short shots, deformation, cracking, and porosity—arise from feedstock, injection, debinding, and sintering issues. Prevent them by optimizing flowability, temperatures, pressure, debinding curves, supports, and sintering density, with SPC...

How Hot Isostatic Pressing (HIP) Makes MIM Parts Denser and More Fatigue-Resistant

Hot isostatic pressing (HIP) is a post-processing technique for MIM parts that uses high temperature (900~1200°C) and high-pressure inert gas (100~200 MPa) to close internal pores via atomic diffusion, raising density from 96%~98% to over 99.5% and i...
