Quality control and documentation
Configure quality assurance for CNC machining online
At InstaWerk, you can easily order milled parts, turned parts, and other CNC components online and select relevant quality control options directly during the ordering process. Our manufacturing platform combines digital online ordering with industrial manufacturing quality, traceable testing processes, and documented proof of quality.
Whether prototype, small series or series production: For technical components, not only precise CNC machining is crucial, but also the appropriate documentation. That’s why InstaWerk offers a selection of frequently needed test reports, material certificates, declarations of conformity and commercial documents directly online.
Any additional requirements can be requested individually via email. These include, for example, different sample sizes, additional test characteristics, mechanical tests, customer-specific forms, or special documentation requirements.

An overview of all our options for your turned and milled parts
Premium test report with KMM measurement
An initial article inspection report (IIMR) documents that a component has been manufactured according to the required specifications. This option is particularly suitable for quality-critical components, series production launches, new supply chains, or internal approval processes.
The EMPB includes a component description, a premium measurement report with CMM or KMM testing for up to 5 parts, a material certificate and, if agreed, documentation of the relevant manufacturing processes.
The EMPB thus supports a structured technical release of milled parts, turned parts and other components from CNC machining.
Initial Sample Inspection Report EMPB
The premium inspection report is the ideal option when precise component characteristics need to be documented metrologically. As part of our premium quality assurance service, your CNC milled or CNC turned parts are inspected using modern, calibrated measuring and testing equipment. For suitable geometries, this also includes coordinate measuring technology (CMM).
The test results are documented in a signed test report. Please indicate the relevant test features in the technical drawing. If no specific information is provided, we will inspect all explicitly toleranced dimensions, fits, and form and position tolerances. Threads and fits will be checked with suitable gauges where possible.
The premium test report includes measurements on up to 5 components. Different sample sizes can be specified in the “Manufacturing Notes” field.
2.1 Factory certificate according to DIN EN 10204
The factory certificate according to DIN EN 10204 type 2.1 is a manufacturer’s declaration. It confirms that the delivered components comply with the agreed specifications.
Individual testing of the delivered components is not part of this certificate. The 2.1 factory certificate is suitable for orders requiring formal confirmation of conformity, but where batch-specific test results are not necessary.
2.2 Factory certificate according to DIN EN 10204
The factory certificate according to DIN EN 10204 type 2.2 also confirms that the delivered components meet the agreed specifications. In addition, it contains non-batch-specific test values, which may, for example, originate from similar production batches or internal tests.
This option is useful if, in addition to the declaration of conformity, supplementary test values are required, but a specific test certificate for the actual delivered batch is not necessary.
Material verification
The material verification serves to document the material used. Depending on availability, it includes a test certificate according to EN 10204 type 3.1 or a material data sheet, supplemented by a spectral analysis of the chemical composition of the delivered batch.
This option is particularly relevant when material traceability, material conformity, or internal quality requirements need to be documented. Especially for technical milled and turned parts, material verification is an important component of the order documentation.
Materials testing by an independent testing laboratory
In materials testing, the chemical analysis of the delivered batch of material is carried out by an independent and accredited testing laboratory, for example by TÜV or SGS.
Mechanical testing is available upon request. This option is suitable for applications with increased requirements for material conformity, component safety, or external verification obligations.
Roughness measurement report
The roughness measurement report documents defined surface roughness values on the manufactured components. Up to 5 roughness values can be specified.
Please mark the exact measuring points in the technical drawing. This ensures that the inspection is carried out on the functionally relevant surfaces. Different sample sizes can be specified in the “Notes for Manufacturing” field.
This option is particularly relevant for CNC milled and turned parts with sealing surfaces, sliding surfaces, mating surfaces or visually demanding surfaces.
Heat treatment protocol
The post-heat treatment protocol documents the steps performed during the heat treatment process. The report is prepared by the post-treatment operator and contains detailed documentation of the relevant process steps.
This option is suitable for components where heat treatment, microstructure properties or strength requirements need to be documented in a traceable manner.
Certificate of Origin (Chamber of Industry and Commerce)
A certificate of origin is a trade policy document that certifies the country of origin of a product. It is frequently required for international shipments, customs procedures, or customer import requirements.
For CNC components ordered via InstaWerk as an online manufacturer, a certificate of origin from the Chamber of Industry and Commerce (IHK) can be selected as additional documentation.
Country of origin and HS code on invoice
ith this option, the country of origin and the HS code or commodity code of all items on the invoice will be shown.
This supports customs and trade-related documentation, especially for cross-border deliveries or internal compliance processes.
Self-declaration REACH and RoHS
InstaWerk has REACH and RoHS compliance agreements with all its manufacturing partners. Upon request, we will provide you with our general REACH and RoHS compliance declaration as a signed PDF document.
This self-declaration helps companies comply with regulatory requirements and internal compliance guidelines.
Self-declaration regarding Russia sanctions
InstaWerk has sanctions agreements in place with all its manufacturing partners regarding Russia. We will provide you with our general Russia sanctions compliance declaration as a signed PDF document.
This option is suitable for companies that require additional evidence of sanctions-related requirements as part of their procurement process.
Supplier Code of Conduct
InstaWerk has a comprehensive supplier code, also called Code of Conduct or COC, which has been agreed upon with all manufacturing partners.
We are providing you with the signed supplier code of conduct agreement as a PDF document. This will give you formal documentation outlining the basic requirements for responsible collaboration within the manufacturing network.
Confidentiality agreement GHV
For confidential projects, we will provide you with a signed non-disclosure agreement (NDA) as a PDF document. This document is signed by the client and then returned to InstaWerk.
This option is particularly relevant for new product developments, protected designs, confidential drawings, or safety-critical projects.
ISO 9001 certified manufacturing partner
By selecting this option, the entire order will be fulfilled by an ISO 9001 certified manufacturing partner. InstaWerk will issue a signed confirmation of this.
This gives you additional assurance that your milled parts, turned parts or other CNC components are manufactured within a certified quality management system.
Self-declaration POP
InstaWerk has POP compliance agreements with all its manufacturing partners. Upon request, we will provide our general POP compliance declaration as a signed PDF document.
This self-declaration supports the documentation of regulatory requirements within the framework of professional procurement and quality processes.
Further tests and documentation available upon request.
The online options cover frequently required aspects of quality control, material documentation, compliance, and export documentation. Additional documentation or testing services can be requested individually via email.
This includes, for example, customer-specific test plans, extended sample sizes, additional measuring points, mechanical material tests, special documentation formats or project-specific release documents.
InstaWerk thus combines the speed of a digital manufacturing platform with the flexibility of professional industrial procurement.
