Manufacturing inside CHUANGJIN

From formed steel to a tested clutch.

Mould development, stamping, heat treatment, machining, laser welding, assembly and inspection centered on heavy-duty commercial vehicle clutch production.

01Stamping
Manufacturing Overview

Process control tied to clutch performance.

Each process has a specific job: geometry begins with tooling and stamping; material behavior is influenced by heat treatment; machining controls fit; welding and assembly control the final clutch structure.

Connected production stages give the team a clear line of responsibility from formed component geometry through final assembly and inspection.

Process Flow

Eight connected stages.

  1. 01Stage

    Mould Development

    Tooling development and maintenance support stable stamping geometry for clutch covers and related formed components.

  2. 02Stage

    Stamping

    Controlled forming processes produce clutch-cover and disc components before machining and heat-treatment stages.

  3. 03Stage

    Heat Treatment

    Heat treatment is applied where specified to achieve the required component hardness and mechanical behavior.

  4. 04Stage

    Machining

    Application-specific dimensions, mounting interfaces and running surfaces are machined under process control.

  5. 05Stage

    Laser Welding

    Robotic laser welding joins clutch-disc components with a narrow, controlled weld zone.

  6. 06Stage

    Assembly

    Friction facings, hubs, damper systems, covers and pressure components are assembled to the product specification.

  7. 07Stage

    Clutch Testing

    Relevant checks can include dimensions, runout, dynamic balance, clamping force and release performance.

  8. 08Stage

    Packaging & Traceability

    Product identification, batch records and export packaging support delivery and after-sales follow-up.
