A single campus that takes raw metal powder to a finished, inspected, export-ready part — without subcontracting, without hand-offs, without excuses.
From feedstock preparation to final inspection, every step happens on our own campus — controlled, traceable, accountable.
Pre-alloyed metal powder storage, climate-controlled, batch-traceable from supplier to feedstock mixer.
Custom binder formulations tuned for stainless, low-alloy, and tool-steel powders. 100% in-house.
32 injection machines (50T–400T). Closed-loop process control. Operator-staffed, not lights-out.
6 vacuum sintering furnaces (XPS-series), 1,200 t/yr combined capacity, 1,250–1,380°C working range.
Vacuum and atmospheric furnaces for quench, temper, and aging — optional per spec.
25+ CNC lathes and machining centers. Tolerance to ±0.02 mm on critical dimensions.
CMM, hardness, density, roughness, metallographic — every batch verified before pack-out.
10,000+ part samples on display — bring your drawing, find a reference part, leave with confidence.
Our MIM lines run stainless steel (304/316L/17-4PH), low-alloy steel, and tool steel feedstocks. Every batch is bar-coded at receipt, traceable through compounding, molding, debinding, and sintering — so when you ask "where did this part come from," we have a complete answer in under 60 seconds.
Our "压制区" (suppressed area) runs 8 injection machines in parallel, with trained operators on every shift. Lights-out automation sounds efficient — but for parts that go into medical devices, locks, and coffee grinders, we want a human eye on every cycle.
Our 6 vacuum sintering furnaces (XPS5-class) deliver consistent density, controlled carbon content, and tight dimensional tolerance. For parts that go into high-stress or safety-critical applications, sinter quality is non-negotiable — that's why we run our own furnaces, not sub-contracted batch service.
Some features can't be net-shaped — threads, bearing surfaces, mating faces, critical datums. Our CNC bay has 25+ machines running lathing, milling, grinding, and drilling, with operators who understand both the print and the process.
Our inspection lab runs the full battery — dimensional, mechanical, metallurgical. No part leaves the floor without a documented pass.
Nikon / LK Metrology bridge-type CMM. 750 × 500 × 500 mm travel. Full GD&T reporting per ISO 1101.
WH-series microhardness tester for thin sections and surface-hardened parts. HV0.1 to HV10 range.
Water-bath density measurement per ASTM B311. Sintered density ≥ 95% theoretical for standard alloys.
Universal testing machine for tensile and yield strength on sample coupons. Per ASTM E8 / ISO 6892.
Sectioning, mounting, polishing, and microscopy. Microstructure review for grain size, porosity, and phase.
Roughness profilometer for Ra, Rz, Rq on machined and as-sintered surfaces. Per ISO 4287 / 4288.
Equipment is easy to buy. Expertise takes decades. SINTS has been making MIM parts since 2000 — long enough to know which alloys crack under which cooling rates, which tolerances are realistic, and which "minor" drawing notes will cost you a week in tooling rework.
10,000+ sample parts on display, organized by industry and alloy. Plus the certifications that make your procurement team stop asking questions.
Our showroom is a working reference library. When a buyer walks in with a print, our engineers can usually point to a similar part we've made, identify the alloy and tolerance range, and quote from real production data — not from a sales spreadsheet.
We host buyer audits every month — typically 1–2 days, covering production lines, inspection lab, document control, and a working session with our engineering team. Travel coordination and on-site translation provided.
