Product Description

Custom Metal Injection Molding parts - We support

Feasibility & Cost Advice – Guide material, design, and production costs
Design for Manufacturability (DFM) – Optimize parts for efficiency and tolerance
Prototyping & Sampling – Produce samples to validate design and assembly fit
Process & Quality Guidance – Recommend heat treatment, coating, and finishing
Mass Production Management – Ensure consistent dimensions and mechanical reliability
Progress & Delivery Tracking – Keep production visible and lead times predictable

When MIM Makes Sense

Complex Geometry

Small Precision Parts

High Volume Production

Undercuts, blind holes, thin walls, and intricate internal features that are difficult for CNC machining.

Best suited for components typically 1g–50g with fine structures and tight tolerances.

After tooling investment, MIM significantly reduces per-unit cost for large batches.

What You Actually Get

High Design Freedom – Complex parts without multiple machining steps
Near-Fully Dense Metal – Up to 99% density, high strength
Excellent Surface Quality – Smooth finish for plating, polishing, PVD
Cost & Time Efficiency – Choosing BestPro's one-stop MIM service saves time, process costs, and improves production stability

Processes Description

Feedstock Compounding 
The metal powder is evenly mixed with the organic binder and granulated to form the feed material 
Injection Molding 
The feed material is injected into a green body with a complex shape under semi-solid conditions 
Debinding Process 
The binder is removed from the green body after debinding 
MIM Sintered 
The final product with good mechanical and physical properties is sintered at high temperature 

Selection Criteria	Recommended Process
Complex geometry with undercuts, blind holes, or internal grooves	MIM
High precision or fine surface finish required	MIM
Parts need to bear mechanical load or require high strength	MIM (can be heat-treated/HIP)
Cost-sensitive, moderate strength, simple shape	PM
Large batch size and larger part dimensions (>30mm)	PM (MIM suits small parts)
Iron-, copper-, or bronze-based materials with simple structure	PM
Small, high-value parts in electronics, medical, or precision tool industries	MIM
