Industries We Serve
JIAYI cutting tools are deployed across mission-critical manufacturing sectors, from commercial aerospace to medical device production.
01Aerospace & Aviation
Titanium and Inconel structural components, turbine housings and hydraulic actuation systems.
From single-crystal turbine blade roots to large-frame fuselage ribs, JIAYI tooling holds tight tolerances in heat-resistant superalloys (Inconel 718, Waspaloy) and Ti-6Al-4V. Optimised geometries reduce work hardening, extend tool life on 5-axis pocketing, and meet AS9100 traceability for tier-1 aerospace suppliers.
- Turbine blade & disc machining
- Landing gear actuators
- Structural pocketing in Ti-6Al-4V
- Engine casing port tools
02Automotive Manufacturing
Powertrain, transmission housings and high-volume valve body machining.
High-volume automotive lines demand predictable cycle times and minimal tool changes. JIAYI’s coated carbide drills, step tools and combination cutters are validated on transfer lines for cast-iron blocks, aluminium heads and steel transmission components — supporting both ICE and EV motor housing production.
- Engine block & cylinder heads
- Transmission valve bodies
- EV motor housings
- Brake calipers & steering knuckles
03Medical Devices
Surgical instruments, implants and precision micro components in titanium and stainless.
Medical machining requires burr-free surfaces, biocompatible materials and micro-geometry control. JIAYI micro end mills and Swiss-type tools handle Ti-6Al-4V ELI, CoCrMo, PEEK and 17-4PH stainless for orthopaedic implants, dental abutments and minimally invasive surgical instruments — with full lot traceability for FDA / ISO 13485 environments.
- Orthopaedic & spinal implants
- Surgical instrument tips
- Dental abutments
- Bone screws & plates
04Hydraulics & Fluid Power
Cartridge valve cavities, manifold ports and custom hydraulic form tools.
JIAYI is a recognised specialist in hydraulic cavity, port and form tooling. We machine and supply cavity tools matched to Sun Hydraulics, HydraForce, Parker, Bosch Rexroth, Eaton and Danfoss standards — single-shot or modular sets — with custom geometries on request for proprietary manifold designs.
- Cartridge valve cavities
- Manifold block production
- SAE / ISO port machining
- Custom manifold form tools
05Power & Energy
Wind turbine gearboxes, oil & gas tooling and downhole threaded connections.
Energy-sector parts run large, heavy and expensive — a failed tool can scrap a six-figure forging. JIAYI deep-hole drills, indexable threading inserts and API thread tooling are engineered for wind gearbox shafts, downhole tubulars, valve bodies and nuclear / hydro components where reliability outweighs raw speed.
- Wind turbine main shafts & gearboxes
- Oil & gas valve bodies
- API / OCTG threading
- Hydro & nuclear components
06Electronics & Semiconductors
PCB routing, micro-machining and ceramic substrate processing.
Electronics manufacturing pushes diameters down to 0.1 mm and demands chatter-free cuts in copper-clad laminate, aluminium nitride, alumina and CFRP. JIAYI micro routers, diamond-coated end mills and PCD tooling support PCB depaneling, semiconductor jig machining and heat-sink production.
- PCB routing & depaneling
- Heat sink finishing
- Ceramic substrate machining
- Semiconductor jigs & fixtures
07Shipbuilding
Marine gearboxes, propulsion components and large diameter hydraulic systems.
Marine propulsion and deck machinery rely on large gears, heavy shafts and oversized hydraulic manifolds. JIAYI supplies gear cutters, large-diameter cavity tools and deep-hole drills sized for marine gearbox cases, rudder actuators and winch hydraulics — built to perform on manganese steels and duplex stainless.
- Marine gearbox cases
- Rudder actuators
- Winch & deck hydraulics
- Propulsion shafts
08Rail Transit
Brake systems, bogie hydraulics and rolling stock manifold port machining.
Rolling stock combines safety-critical brake hydraulics with high-volume bogie and coupler production. JIAYI port tools, cavity cutters and indexable drills are deployed across high-speed rail, metro and freight programmes — meeting EN / IRIS quality requirements for repeatable port geometry and surface finish.
- Brake control manifolds
- Coupler & draft gear machining
- Bogie hydraulic blocks
- Suspension actuators
