Quality Control For Metal Stamping Fabrication

Quality Assurance (QA) testing refers to the process of inspecting and verifying that metal stamping products meet the required standards. The ability of metal stamping manufacturers to deliver parts on demand largely depends on the level and extent of the quality control inspection they provide.
At Metaco, we recognize the importance of quality control assurance for OEM metal stamping parts, which is why we have a comprehensive in-house quality inspection department and quality control assurance equipment. Here, you will learn how we ensure full-process quality control for custom metal stamping parts.

Quality Control in Die Evaluation

The development of a stamping part prototype often begins with the development of a die. Depending on the complexity of the part, customizing a tool may take between 8 to 26 weeks.

During the die design phase, the die makers creates plans based on the production and key characteristics of the parts, considering the expected lifespan of the die to ensure stability and reduce downtime.

Numerical simulation methods are used to evaluate the rationality of the die design, predicting potential forming defects, and avoiding issues such as breakage, wrinkling, and dimensional accuracy problems caused by spring-back during forming.

Quality Control in Sample Evaluation

Although making samples incurs additional costs, initial testing phase adds time, this step is essential. It helps avoid other costly problems during production, thus increasing the cost.

If sample costs are too high, the die maker can also use simulations to evaluate the functional strength requirements of the part design and optimize the part design.

Quality Control in Packaging

Packaging depends on the characteristics of the parts and their usage on the assembly line. Some parts can simply be thrown into a bin as loose items, while others should be packaged in strips for automatic assembly at the manufacturing plant. Some be neatly arranged in boxes by the commissioner.

Similarly, bendable parts that must maintain precise dimensions should each be individually packaged to avoid damage during transport or assembly. Cost factors typically determine packaging, but overall costs including transportation, handling, storage, and processing must be considered.

Utilizing APQP for Quality Control Planning

The APQP process was developed by auto manufacturers and involves parts suppliers in every step of prototype and launch processes—from initial prototype to product launch and beyond. The APQP process monitors over 20 areas before production begins, including design robustness, design testing, quality inspection standards, and product packaging.

Quality Control for Secondary Services

The quality of parts requiring secondary processing is also under our strict supervision.Parts delivered by external manufacturs are inspected against standards before shipment to Metaco. Upon arrival at our factory, these components undergo a secondary inspection. Only those meeting our specifications are packaged and stored; parts failing to meet quality standards are returned for rework or remanufacturing. This ensures quality control throughout all stages of production.

At Metaco, everything we do, from the metal stamping process to secondary services, strictly adheres to our quality production standards. We offer custom precision metal stamping services for critical industries such as automotive, water treatment, and electronics, and have established a solid reputation.
