Sample Confirmation Process

Sample confirmation process

It seems that the sample confirmation process is only a small step in the production process, but it is directly related to the success or failure of the product and the production cost. If any omissions occur in any link, this may cause significant losses to subsequent mass production.

Establish purpose and scope

The core goal of this process is to identify problems in advance. Before the new product is put into formal production, systematic sample confirmation measures are used to ensure that the actual product is fully consistent with the design drawings and customer expectations . The custom parts processing sample confirmation process can intercept potential quality defects at the source and prevent economic losses and time delays caused by the production of a large number of substandard products.

Its scope of application is not limited to new product development. When existing products require material changes, process improvements, or functional improvements, this process must also be implemented. In addition, for special customized orders put forward by customers, even if they are similar to existing products, separate production and sample confirmation operations must be carried out to prevent variables outside the standard process from causing problems.

Sample application and review

Sample application is the starting point of the process. It is usually the applicant's sample confirmation process for R&D or sales department personnel. A detailed application form must be filled in. The content of the form must include the exact specifications of the sample, the required quantity, the specific purpose and the expected completion time. All relevant technical drawings and parameter files must also be attached.

After the application is submitted, the production planning department or the technical management department will conduct an review. The focus of the review is to evaluate the necessity of sample production, the feasibility of technical requirements, and the rationality of resource allocation. Only applications that pass the review will be officially included in the sample production plan. This can effectively prevent arbitrary and invalid sample production requests from occupying production resources.

Sample production and recording

After receiving the order, the production workshop will arrange a special team or machine to make samples. The production process must strictly follow the technical documents submitted during the application. Operators cannot change the process parameters without authorization based on their own experience. The materials used should also be consistent with future mass production.

After the sample production has been completed, the production personnel must record the entire process in detail, covering the equipment used, specific operating steps, key process parameters, and actual time consumption. Any abnormal situations encountered during production also need to be recorded. This record is for subsequent inspection and an important original basis for problem tracing.

Sample inspection and feedback

The quality inspection department conducts comprehensive inspections of samples in accordance with established inspection standards. Inspection items are generally divided into several categories such as appearance, dimensional accuracy, physical performance, assembly function, and safety. Inspectors must use professional measurement tools and equipment to obtain objective and quantitative data.

Any inspection result, regardless of whether it is qualified or not, must be reported in writing. If the sample fails, the report must clearly indicate the non-conforming items, specific deviation values, and analysis of possible causes. The report in this case will be immediately fed back to the application department and production department, which will become a direct basis for sample adjustment or process improvement.

Sample confirmation and approval

Samples that pass internal inspection will be handed over to the department that originally submitted the application for final confirmation. The confirmation work is usually completed by the project leader or designated engineer. They need to simulate actual usage scenarios to verify whether the sample can fully meet the preset function and performance requirements.

After confirming that there are no errors, the applicant needs to sign on the official sample confirmation document for approval. This signed document has legal effect, which means that the status of the sample has been frozen, and subsequent mass production must be carried out strictly in accordance with the standards set by this confirmed sample. At the current stage , custom parts processing sample confirmation process, custom parts processing sample confirmation process , sample management responsibilities have been transferred from the research and development stage to the production stage.

Process documentation and continuous improvement

All documents related to samples, including application forms, drawings, production records, inspection reports and confirmation sheets, must be filed by the quality department. These files are numbered and saved to ensure that they can be quickly accessed and traced throughout the entire life cycle of the product, which is of great significance for handling customer complaints and quality incidents.

Enterprises should review the execution status of the sample confirmation process every quarter or every six months, collect feedback from various departments such as production, quality inspection, R&D, etc., and make statistics on the sample pass rate, average production cycle, and many other data. Based on these real feedback and data, optimize the unsmooth links in the process, such as simplifying forms, clarifying responsibilities, or updating inspection methods to continuously improve efficiency.
