CNC machining for aerospace supply chains
AS9100D Certification and CNC Machining
We provide custom CNC milling, turning, turn-mill, and Swiss-type machining for drawing-based components. Our quality management systems include AS9100D / EN 9100:2018, ISO 9001, ISO 14001, ISO 13485, and IATF 16949, each with its own stated scope.
For aerospace-related enquiries, we review the applicable drawings, purchase terms, and quality requirements before confirming whether a project fits our capabilities and certification scope. Certification alone does not qualify us for every aerospace program: each order remains subject to customer approval and applicable requirements.

Review before order confirmation
We compare the drawing and revision, customer terms, quality clauses, and our current certification scope and manufacturing capability before confirming fit.
Certificate verification
Current AS9100D / EN 9100 certificate details
The details below are taken from the Bureau Veritas Certificate of Approval for Shenzhen Yijin Hardware Co., Ltd. The certificate covers BS EN ISO 9001:2015 and EN 9100:2018 (technically equivalent to AS9100D). Request a copy when you need the full document for supplier qualification.

How we manage requirements
A quality-system framework for applicable work
For projects within our confirmed certification scope, we use our quality management system to manage production and inspection in line with applicable requirements. We review customer-specific terms alongside the drawing before accepting an order.
Review the part and its terms
We assess the drawing, revision, technical specifications, inspection criteria, and purchase clauses. If a requirement is unclear or cannot be confirmed, we raise it for review before proceeding to help identify risks affecting manufacturability, verification, or delivery.
Work to agreed revisions
We use the customer-approved drawing and agreed order requirements as the production basis. Changes to a drawing revision, specification, or other requirement should be reviewed and agreed before affected work proceeds. Include your change-control instructions in the RFQ so we can assess their application.
Match inspection to the part
Our dimensional inspection resources include a coordinate measuring machine, optical measuring systems, height measuring instruments, concentricity measurement, surface roughness testing, hardness testing, and dimensional gauges. Methods and records depend on part features and customer requirements. Specify key characteristics, acceptance criteria, inspection frequency, and required deliverables such as reports.
Confirm documentation expectations
Material identification, traceability records, and supplier-related controls may depend on customer and order requirements. We do not assume a particular material certification, traceability format, or supplier approval status. Share applicable clauses and documentation expectations so we can confirm what can be supported before order placement.
Manufacturing capabilities
CNC machining for varied component geometries
Our equipment supports a range of part forms and production needs. Listed machine precision is not a guaranteed tolerance for every part; achievable tolerances depend on geometry, material, feature relationships, machining method, and inspection requirements. We review these factors against your drawing before confirming a quotation.
CNC milling
25 three-axis machines, one four-axis machine, and eight 5-axis CNC machines. Examples include brackets, housings, mounting plates, and multi-sided components.
CNC turning
43 CNC lathes, plus gang-type and automatic lathes, for shafts, sleeves, bushings, connectors, and other turned parts.
Turn-mill
15 machines for components combining turned and milled features.
Swiss-type machining
10 Swiss-type lathes, including five-axis and six-axis machines, for small or slender components.
Supporting operations
Screw machines, conventional milling machines, and small surface grinders.
Supplier assessment
What to include in an aerospace RFQ
The more complete the order requirements, the better we can assess fit and provide a useful response. Specific orders must meet the applicable customer technical specifications and supplier-entry requirements.
We review those requirements alongside our current certification scope and manufacturing capability before confirming whether we can support the work.
- Latest part drawing and revision level
- Applicable material, process, and product specifications
- Purchase terms and customer-specific quality clauses
- Material documentation and traceability expectations
- Key characteristics, tolerances, and inspection criteria
- Required inspection records and other deliverables
- Prototype or production quantities and expected order frequency
- Supplier qualification, audit, or approval requirements
Common supplier review questions
Clarify scope, approvals, and order requirements
Does AS9100D certification automatically qualify us for an aerospace program?
No. Certification alone does not establish approval for every program. Each order remains subject to customer approval, applicable technical specifications, supplier-entry requirements, and confirmation that the work fits our current certificate scope and capabilities.
Can you confirm the certificate entity, scope, validity, and certification body?
Those details are not stated in the company information provided here. Please request our current certificate; it is the authoritative source for the certified legal entity, scope, certificate number, validity period, and certification body.
Can you provide the inspection and material records our order requires?
Requirements vary by part and order. Send the applicable acceptance criteria, inspection deliverables, material documentation, and traceability clauses with your RFQ so we can review what can be supported before order placement.
Discuss your requirements
Send your drawings and quality requirements for review
Share your drawings, purchase terms, and quality audit requirements. We can review the machining approach, inspection expectations, and certification documentation relevant to your enquiry.
We will assess your requirements against the current certification scope and manufacturing capability before confirming whether we can support the work.
