Process Capabilities

Five Core Process Capabilities

Metal Injection Molding (MIM)

MIM produces small, complex, high-precision components that are difficult to machine. Built on self-developed feedstock, every step from feedstock formulation to injection molding, debinding and sintering is tightly controlled for predictable shrinkage and stable quality.

Powder Metallurgy (PM)

Press & sinter PM delivers high-density structural parts with excellent mechanical strength and minimal material waste. NEWLIFE's PM lines support tungsten alloys, iron-based and copper alloys, and soft magnetic materials — replacing conventional machining and small castings at medium-to-high volumes.

Secondary Precision Machining

While PM and MIM provide near-net-shape parts, in-house secondary machining — CNC milling and turning, drilling, tapping and grinding — secures tight tolerances on assembly-critical features, delivering assembly-ready parts with shorter lead times.

Surface Treatment

Polishing, plating, coating, passivation and anti-corrosion treatments enhance corrosion resistance, wear performance and functional properties. Integrated into the production flow, we deliver finished parts ready for medical, electronics, automotive and industrial use.

Material & Powder Engineering

With over 20 years of experience, NEWLIFE develops micron- and nano-scale iron, copper and nickel powders in-house. Controlling particle size distribution, morphology and purity delivers better sintering behavior, stable quality and an optimized cost structure — integrated from powder to parts.

MIM vs. Precision CNC Machining

Aspect	Precision CNC Machining	MIM
Geometry complexity	Limited by tooling	Highly complex
Cost per part	High for complex parts	Lower at volume
Tolerance	Very high	High and consistent
Production volume	Low–medium	Medium–high
Material waste	High	Very low

Traditional PM vs. Conventional Machining

Aspect	Conventional Machining	Traditional PM
Material utilization	Low (high scrap rate)	High (near-net shape)
Cost per part	Increases with complexity	Decreases with volume
Batch consistency	Process-dependent	Naturally consistent
Best fit	Low-volume, high flexibility	Medium–high volume parts

MIM vs. Investment Casting

Aspect	Investment Casting	MIM
Minimum feature size	Moderate	Very small
Surface finish	Moderate	Smooth
Dimensional accuracy	Moderate	High
Secondary machining	Often required	Minimal

MIM advantages over casting: better dimensional consistency, reduced finishing and machining, improved surface quality.

Traditional PM vs. Casting

Aspect	Casting	Traditional PM
Dimensional accuracy	Moderate	High
Internal defects	Shrinkage, porosity	Controlled porosity
Secondary machining	Often required	Minimal
Part size	Small to large	Small to medium

PM is preferred when tighter tolerances are required, post-machining must be minimized, and consistent mechanical performance is critical.

Multi-Part Assemblies → Single MIM Component

MIM often replaces assemblies made from multiple machined components — a conventional solution of multiple machined parts plus assembly becomes a single integrated MIM component.

Part consolidation
Reduced assembly cost
Improved reliability

Where Traditional PM Is Not the Best Choice

Traditional PM is not intended to replace:

Ultra-high precision CNC machining (±5 μm or tighter)
Large structural castings
Highly complex internal geometries (better suited for MIM)

This is where Metal Injection Molding (MIM) or advanced machining becomes the preferred solution.

Tooling Capability

Complex MIM molds

MIM molds are far more complex than conventional PM molds: a single set costs 25,000–50,000 RMB and weighs over 100 kg — about 10× the weight of a PM mold.
