Small Complex Metal Parts Metal Injection Molding

Metal injection molding combines powdered metal with a binder, injects it into molds, then heats it to remove the binder and sinter it into a durable part. Suitable for small, complex, high-precision metal parts manufacturing. The material selection range is wide, such as iron-based, nickel alloy, tungsten alloy, titanium alloy, superalloy alloy, etc.

What Is Metal Injection Molding Service

Our metal injection molding Service specializes in transforming metal powders into complex parts and components. We offer multi metal powder injection molding molding process. Such as iron base, tungsten, titanium, magnetic, and cobalt alloys injection molding. We produce high precision and strong custom MIM parts.

Benefits	Key Features
Complex Geometry Capability	Metal Injection Molding (MIM) excels in producing complex, precision-engineered components with intricate details and geometry that other metalworking processes cannot achieve. This allows for integrating design features such as undercuts, threads, and fine surface details without additional machining.
High Precision and Consistency	MIM achieves exceptionally high precision and consistency max +/-0.03mm, making it ideal for producing large quantities of parts where uniformity is crucial. This process ensures each part meets strict dimensional tolerances and surface finish requirements.
Material Efficiency	MIM is highly material efficient 95~98%, utilizing fine metal powders bound and injected into a mold. This process minimizes waste as excess material can often be recycled, reducing the overall material cost and environmental impact compared to traditional manufacturing.
Strength and Integrity	Parts produced via MIM possess excellent mechanical properties, including high density and strength comparable to wrought materials.

MIM Vs. PCM

Metal Injection Molding (MIM) and Powder Compression Molding (PCM) are distinct manufacturing processes. MIM uses fine metal powders for high-precision, complex parts, while PCM compresses powder into simpler shapes with lower precision. MIM is costlier and suited for medium to high volume production, whereas PCM is more economical for lower volumes.

Process	Pictures	Forming	Materials	Density	Precision	Cost	Volume	Applications
Metal Injection Molding		Injection molding of metal powders mixed with a binder	Stainless steel, titanium, tungsten, etc.	95-98% of theoretical	High +/-0.03mm	Higher	Medium to high	Complex small components (e.g., medical, automotive)
Powder Compression Molding		Compression of powder into molds	Iron, steel, ceramics, etc.	Up to 90% of theoretical	Medium to High +/-0.05mm	Lower	Medium to high	Simpler parts with less complexity (e.g., gears, bearings)

Design Elements	Standard/Specifications	Reasons
Max Size	250 mm x 250 mm x 250 mm	Oversized MIM parts are prone to collapse and deformation during high-temperature debinding and sintering due to their weight and high temperature.
Min Size	3 mm x 3 mm x 3 mm	Minimum size limited by the ability to fill the mold properly with the feedstock and maintain structural integrity.
Min Wall Thickness	0.4 mm	Thickness depends on the ability of the feedstock to flow within the mold without defects.
Max Wall Thickness	10 mm	Thicker sections slow cooling, risking defects like warping or internal stresses.
Min Net Weight	1 gram	Below this weight, parts may not maintain structural integrity or detailed features.
Cost-effective Max Weight	100 grams	Maintains a balance between moldability and economic production without excessive material use.
Max Net Weight	5 kg	The upper limit for maintaining process control and quality in larger parts.
Precision Range	+/- 0.3% to +/- 0.5%	Standard precision for MIM, suitable for most high-performance applications.
Min Tolerance	±0.005 inch	Reflects the high precision achievable with MIM, critical for intricate parts in demanding sectors.
Cost-effective MOQ	10,000 units	The specific minimum order quantity depends on the sintering quantity per furnace. MIM parts are sintered at a particular temperature using a vacuum furnace. The cost of sintering one part is the same as a full furnace of parts. The minimum order quantity is usually the number that can be sintered in one furnace.
Max Efficiency	95% material utilization	Reflects the high material efficiency of MIM, minimizing waste and maximizing resource use.
