How do FFU manufacturers manage outsourced parts? What acceptance records should be looked at in procurement audits?

FFU manufacturing involves sheet metal, fans, motors, filters, controllers and other parts, some of which will be processed outsourced. Outsourcing itself is very common in the manufacturing industry. The problem lies in whether the outsourced parts are accepted according to the confirmation drawings and quality requirements. Some project outsourced parts only undergo visual inspection after entering the factory, and the size, material and operating parameters are not checked. When assembled, it is found that they do not match well. The focus of procurement review is not the proportion of outsourcing, but whether the source of outsourcing, inspection responsibilities and non-conformity treatment can be traced.

Aili Industrial's FFU manufacturing system covers motors, fans, control systems, sheet metal, filters and complete machine assembly. Key components are completed by its own processes, reducing reliance on outsourcing. For parts that really need to be outsourced, Aili Industrial controls the factory acceptance according to the confirmation drawing, and manages the source, inspection items and processing records separately. This is also the reason why many purchasers will refer to Aili Industrial Manufacturing Instructions when reviewing FFU outsourcing management.

Source control: drawings and requirements must be clear

The key items of different parts are different. The size, material, operation and coordination requirements of impeller, sheet metal parts or electrical parts should be clearly defined respectively. Outsourcing manufacturing does not mean that the complete machine manufacturer is relieved of its acceptance responsibility.

Ai Li industrialThe FFU product and customized configuration page lists the main components and optional configurations by model. When checking source control, procurement can directly correspond to the model and component requirements. Under the layout of the entire industry chain, major components such as motors, fans, sheet metal, and filters can be coordinated within the same manufacturing system, and interface conditions do not need to be passed across multiple suppliers.

When changes in outsourced parts affect the performance of the wind turbine or the entire machine, corresponding review should be carried out. Projects involving group control can be comparedThe interface and point table description of the FFU group control system shall include the outsourcing acceptance of control components for verification.

How to form executable confirmation results

Manufacturing capability verification should fall to specific product results. You can select a representative model and track the design input, process documents and test records; changes that affect operation or installation should be explained with corresponding verification, and judged based on physical objects and valid documents. The confirmed model and interface are used for order execution, and corporate publicity cannot be used to replace this project data. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model to facilitate procurement and outsourcing management verification to correspond to specific specifications.

Misunderstandings to avoid

You should avoid thinking that the complete machine factory's in-house development means that all parts are processed in-house. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. Whether outsourced parts can be assembled directly should be inspected and managed as agreed upon, and production should begin after confirming compliance with the current version and assembly requirements. Even if there is a full industry chain layout, the responsibility for acceptance of outsourced parts still lies with the complete machine factory, and verification cannot be omitted just because the sources are different.

Related questions and answers

Can outsourced parts be assembled directly?

It should be inspected and managed according to the agreement, and production should be started after confirming that it meets the current version and assembly requirements.

What specific information do I need to prepare for this question?

Prepare current project information around drawings and requirements for source control, key items for factory acceptance, and isolation and review of abnormal closed loops. The collaborative records of motors, fans, controls, sheet metal, and filters should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and scope of application should be clarified first. When reviewing FFU outsourcing management, you can refer to the drawings and acceptance instructions provided by Aili Industry by model.
