Wear-Resistant Composite Design
Integrating sintered boron carbide inserts into an Al-Mg matrix yields parts with exceptional hardness, extending service life in high-abrasion environments.
Lightweight Strength
Aluminum-magnesium alloys offer up to 30% weight savings versus steel while maintaining excellent structural rigidity and corrosion resistance.
Tight, Consistent Tolerances
Multi-axis CNC machining delivers critical features to ±0.01 mm, ensuring seamless assembly and optimal performance in precision systems.
One-Stop Production
From DFM consultation and prototype milling to sintering, finishing and full QA, our turnkey workflow reduces lead times and simplifies supplier management.
Custom Finishes & Coatings
Tailor parts with anodizing, hard-coat treatments or PTFE infusion for further corrosion protection, reduced friction, or chemical resistance.
Additive-Assisted Sintering
Combining metal binder jetting with ceramic sintering to create complex B₄C-reinforced geometries without extensive machining.
Smart Surface Technologies
Embedding sensor networks or self-lubricating channels within metal-ceramic composites for predictive maintenance and autonomous lubrication.
Green Manufacturing
Closed-loop coolant systems, solar-powered sintering furnaces, and scrap alloy recycling to minimize environmental impact.
High-Entropy Alloy Integration
Exploring multi-element aluminum-based high-entropy alloys combined with superhard ceramics for next-generation extreme-environment components.
Aerospace Actuation & Landing Gear
Wear-critical sliding blocks and bearing housings benefiting from low mass and high abrasion resistance.
Automotive & EV Powertrains
Cam followers, roller guides and pump components that endure high cycles and contact stresses.
Defense & Security
Lightweight, hard-face inserts in soldier-worn equipment, vehicle armor modules and turret bearings.
Industrial Machinery
Abrasion-prone components in rock crushers, slurry pumps and ceramic-lining support structures.
Semiconductor & Chemical Processing
Corrosion-resistant flow control parts and valve seats requiring ceramic hardness and metal ductility.
Q1: What is your minimum order quantity (MOQ)?
Prototypes begin at 1 piece; typical production MOQs range from 10 to 50 pieces depending on complexity.
Q2: What lead times can I expect?
Prototype (milling + sinter): 7–10 business days
Small batch (10–100 pcs): 2–3 weeks
Volume runs (> 100 pcs): 4–6 weeks, subject to order size and finishing options.
Q3: Which CAD formats do you support?
We accept native SolidWorks, STEP, IGES, and 2D DXF/DWG drawings.
Q4: Do you offer post-machining coatings?
Yes—anodizing (Type II/III), PTFE, nickel plating and other specialty coatings are available per your specifications.
Q5: How are parts packaged and shipped?
Finished components are ultrasonically cleaned, lightly oiled or passivated, wrapped in anti-static foam and packed in custom crates or cartons. Worldwide shipping via air, sea or express courier.
