Precision industrial.精密工业
Precision-machined parts and integrated sub-assemblies for industrial OEMs: bearings and motion components, instrumentation, hydraulic and pneumatic systems, conveyor and transport systems, and industrial automation. 316L stainless, hardcoat aluminium, PEEK, Invar where CTE matters. Documented quality, no cosmetic noise — every lot ships with the dimensional data the customer measured against when the design was qualified.
Tight tolerance. Full documentation.严密公差。完整文档
Precision industrial is a B2B vertical for us — industrial OEMs building equipment, instruments, and systems for other industrial customers, not consumer end-users. The deliverable is a precision part or sub-assembly plus the data that proves it. Surfaces are functional, not cosmetic. Finishes are passivation, hardcoat, and electroless nickel — not paint or pattern. Every lot ships with the dimensional report the buyer measured against during qualification.
Who we build for.我们为谁制造
Bearings and motion components are a steady share of the work — precision-machined bearing rings, cartridge bearing housings, spacer sleeves, pulley and sprocket components for conveyor and transportation systems. Tight roundness and concentricity, fine surface finish on race and bore surfaces, full material lot traceability per heat number. 轴承与运动部件是稳定的工作量——精密加工的轴承环、筒式轴承外壳、隔套、用于输送与运输系统的皮带轮与链轮部件。圆度与同轴度严格、滚道与孔表面粗糙度细腻、按炉号做完整材料批次追溯。
Instrumentation and sensor OEMs pull on us for transducer housings, sensor enclosures, optical fixturing, kinematic mounts, low-CTE structural carriers in Invar or composite where dimensional stability matters. Hydraulic and pneumatic systems — manifold blocks, valve bodies, fittings, fluid-handling components — are the third recurring category, with cross-drilled porting deburred to spec and pressure-test verified.
Conveyor and transportation systems and industrial automation round out the mix — bearing assemblies, drive components, sealed enclosures, robotic end-effector base plates, gripper hardware, custom tooling, jig and fixture work. Programs run from low-volume specials (10–500 units) through medium production (10k–50k units per year), with the common thread being tight tolerance and full lot-level documentation. 输送与运输系统、工业自动化构成其余部分——轴承组件、传动部件、密封外壳、机器人末端执行器底板、夹爪五金、定制工装、夹具治具工作。项目从小批量特殊件（10–500件）到中等产量（年1万–5万件），共通点是严公差与完整批次级文档。
How precision industrial draws on our facilities.精密工业如何调用我们的设施
Industrial work is dominated by precision machining, with assembly and functional finishing as the supporting layers. Composites and injection molding play smaller roles — composites for low-CTE instrumentation structures and vibration-damped frames, molding for housings and cosmetic shells where customers want them. Approximate mix below; varies by program. 工业工作以精密加工为主，装配与功能性表面处理为辅。复材与注塑承担较小角色——复材用于低热膨胀仪表结构与减振框架，注塑用于客户需要的外壳与化妆性外观件。下方比例为大致占比，按项目变化。
What precision industrial runs on.精密工业依托的能力
Precision metals and engineering plastics dominate, with carbon composite where dimensional stability or vibration damping warrants it. Mill certs and full lot traceability per heat number provided per shipment; specialty grades stocked or qualified per program. 以精密金属与工程塑料为主，对尺寸稳定性或振动阻尼有要求的项目使用碳纤复合材料。每批出货按炉号提供完整厂商证书与批次追溯；特殊规格按项目备库或验证。
The default stainless for precision industrial work — bearing rings, hydraulic fittings, sensor bodies, fluid-handling components, conveyor hardware. Superior corrosion resistance, low-magnetic, weldable. Per ASTM A276 bar / A240 sheet.
Precipitation-hardening stainless. Tooling, kinematic mount components, high-load fixtures, valve internals. Hardenable to high yield strength while retaining stainless corrosion behaviour.
Free-machining stainless for high-volume Swiss-turned precision parts where corrosion is a factor but weldability is not. Pump shafts, fittings, fasteners, instrument hardware.
General-purpose machined aluminium for hydraulic manifolds, instrument enclosures, optical fixturing, robotic end-effector base plates, and conveyor cartridge bearing housings (typically with Type III hardcoat where wear matters). Anodizes cleanly.
High-strength aluminium for precision robotic end-effectors, structural fixturing, weight-critical instrument components, and high-load mechanical assemblies.
Damage-tolerant aluminium for fatigue-loaded fixturing, repeated-cycle automation parts. Higher fatigue performance than 6061 / 7075 where it counts.
Iron-nickel alloy with ultra-low coefficient of thermal expansion (~1.2 × 10⁻⁶ /K). Used for thermally-stable optical benches, kinematic mount substrates, and instrumentation structures where temperature drift must be kept below typical aluminium or steel.
Free-machining brass for fluid-handling fittings, small-diameter precision turned parts, electrical connector bodies, decorative-functional hardware on premium instruments.
Air-hardening tool steel for fixture inserts, gripper jaws, automation tooling, wear surfaces. Heat-treated to 58–62 HRC; partner-routed heat treatment with documentation chain preserved.
Polyetheretherketone — the highest-performing thermoplastic. Used for sensor bodies in chemical service, fluid-path components, bushings, and seal carriers in instrument and motion programs. 260°C continuous service; chemically inert.
Polytetrafluoroethylene. Used for sealing components, low-friction guides, chemical-service gaskets, and fluid-path parts in instrument and hydraulic programs. Non-stick, chemically inert across nearly all reagents.
Polyoxymethylene. Excellent dimensional stability for tight-tolerance machined plastic parts — gear components, precision sliders, bushings, conveyor wear hardware.
Polycarbonate and acrylic for transparent windows on instrument enclosures, sealed inspection windows, and sight glasses on industrial equipment.
Carbon-fiber prepreg for low-CTE instrumentation structures, vibration-damped optical benches, lightweight robotic end-effector frames. Used where metal can't deliver the stiffness-to-weight or thermal stability the program requires.
Hardcoat anodize per MIL-A-8625 — wear surface, electrically insulating, dimensionally stable finish for industrial and instrument aluminium components. Black or natural bronze; 25–50μm typical.
Uniform nickel-phosphorus deposit for hydraulic and pneumatic components, fluid-path hardware, wear surfaces on aluminium. Conformal across complex porting; corrosion + wear in one process. Partner-routed where the program calls for it.
Citric or nitric passivation per ASTM A967 for 316L and other stainless components, restoring the chromium-oxide layer after machining. Standard pre-treatment for stainless industrial parts in chemical or fluid-handling service.
Black oxide finish on tool steel and carbon steel hardware — fasteners, fixture inserts, gripper jaws. Light corrosion protection plus the matte black appearance industrial customers expect on hardware.
Material certification. Mill certs and full lot-to-part traceability per heat number provided per shipment. Customer-supplied material (CSM) supported with program-locked inventory control. Specialty alloys (Invar, Hastelloy, titanium, Monel, MP35N) qualified per program on request — quoted separately given the supply lead time.

Sending us a precision industrial program.把精密工业项目交给我们
Precision industrial engagement is straightforward. A 3D model with PMI / GD&T, material specification, surface finish callouts, and the documentation requirement set is enough to start a manufacturability review and quote. Volumes from prototype (single-digit) through production (50k / year) supported under the same quality system.
Engineering review before quote.报价前工程评审
Industrial parts often have a critical-feature subset that drives machining strategy and cost — the difference between a 2-day and a 6-day cycle on a manifold can be one tight tolerance the customer didn't realise was tighter than necessary. Most of the value we add upstream of cutting metal is in flagging this and asking the question.
Quote turn-around runs three to five business days for prototype and small-lot work, five to seven for production programs. First article one to two weeks (depends on material lead time and any partner-routed processes). Production schedules typically held to ±2 days.
Have a precision industrial program that needs measurable, documented manufacture?有精密工业项目需要可测量、可记录的制造？
Send a 3D file, drawing with PMI, material specification, and documentation requirement set. A precision program engineer comes back with a manufacturability review, machining-strategy proposal, dimensional-inspection scope, and a direct read on where the program fits our scope — including which tolerance callouts could be opened up if they aren't critical-to-function.
