Business Segments

Two Business Segments

Automotive projects run on a project basis, with emphasis on technical review and compliance support; industrial products run on a quotation basis, with emphasis on brand resources and one-stop supply. The two lines operate independently, each with its own service process.

Our Position

The technical interface between design and manufacturing

Precise technical linkage is required between OEM drawing requirements and the process capabilities of cold forming plants. We translate design requirements into executable process parameters and complete risk review before tooling, so design intent lands accurately on the production line.

01 / DFM

Design for Manufacturability Review

Verify drawing dimensions and tolerances, head forming, thread type, material and heat treatment feasibility item by item; identify design points that affect yield and cost before tooling, and provide actionable optimisation proposals.

Deliverables: DFM review comments + alternative proposals
02 / Failure

Failure Analysis and Prevention

For typical failures such as loosening, fatigue fracture, hydrogen embrittlement delayed fracture, thread stripping and coating flaking, we locate root causes from both assembly conditions and the process chain, supported by a database of 571 failure cases.

Deliverables: failure mechanism assessment + process improvement measures
03 / Substitution

Localisation and Second Sourcing

Benchmarked against imported fasteners, we assess manufacturability and performance equivalence, and deliver substitution comparison and validation paths to improve cost and lead time while maintaining performance and reducing single-source risk.

Deliverables: substitution comparison + validation conclusions
Typical Application Areas

Covering the main fastening applications across the vehicle

Requirements differ significantly by area in terms of load mode, operating environment, assembly process and failure consequences. The following are typical application areas and the corresponding part types.

Services

Service capabilities across the fastener lifecycle

From drawing review to volume delivery, every step has dedicated technical support and deliverables.

DFM Design Review

Assess drawing manufacturability item by item, identify process capability limits and cost risk points, and deliver review comments and optimisation proposals. Feedback committed within 3–5 working days.

Sample Trial Production and Validation

Organise sample trial production, complete dimensional, mechanical and assembly validation, and issue validation records as the precondition for volume production.

Import Substitution Proposal

Benchmark against imported parts to complete manufacturability assessment and performance equivalence analysis, and provide substitution comparison and validation paths balancing performance, cost and lead time.

Quotation and Supply Proposal

Based on review conclusions, issue process plan, price and lead time, including tooling cost notes, with deliverables and responsibilities defined for each milestone.

Failure Diagnosis

Determine the failure mechanism from operating conditions and failure symptoms, and advise on process and assembly improvements to help customers close issues at an early stage.

Import/Export and Supply Chain Services

Provide goods and technology import/export, domestic trade agency and supply chain management services, supporting cross-region procurement and delivery planning.

Technology & Quality

Inspection, Process and Traceable Delivery System

A complete process chain covering cold forming, thread rolling, heat treatment, surface treatment and sorting inspection, with production and delivery organised by batch.

  • 01
    Inspection CapabilityRoutine tests including hardness, torque, metallography, salt spray, dimensions and geometric tolerances, together with key characteristic validation.
  • 02
    Process CoverageCold forming, thread rolling and thread-forming, heat treatment, surface treatment (including zinc-nickel plating) and other complete process chains.
  • 03
    Delivery and TraceabilityBatch traceability with batch-level delivery documents such as material certificates, inspection reports and declarations of conformity.
  • 04
    Management System CertificationThe manufacturing system is certified to IATF 16949:2016, ISO 9001 and ISO 14001; heat treatment and plating processes have passed CQI-9 / CQI-11 process audits.
