I. Introduction

In the current highly competitive perfume packaging industry, the ability to quickly and accurately determine the feasibility of the design for customized perfume lids has undoubtedly become the core element for enterprises to seize the market high ground. As professional engineers who have been deeply involved in the die-casting perfume lids industry for many years, with rich practical experience and profound professional knowledge, we are very familiar with each key link. Next, we will elaborate on how to help customers solve this key problem efficiently and with high quality.

II. Helping Customers Quickly Produce Creative Samples

During the initial creative concept stage of design, the 3D printing sample service we provide plays a crucial role. When customers come up with unique perfume lid design ideas, whether it is in an irregular geometric shape or incorporates fine and intricate textures, for example, conceiving a lid that shows a retro charm and is engraved with European patterns, they only need to communicate with us in time. With a stable and professional 3D printing cooperation network, we can transform abstract design concepts into tangible and perceptible physical models with high efficiency. Customers can thus intuitively judge the degree of fit between the design scheme and their perfume brand positioning as well as the aesthetic preferences of the target consumer group, thereby greatly reducing the time span from the emergence of inspiration to the initial evaluation and injecting strong impetus into the subsequent in-depth design optimization work.

III. Millimeter-level Fine-tuning of Dimensions

Once the preliminary design scheme takes shape, relying on professional and efficient 3D printing resources, we can quickly customize multiple versions of samples with slight dimensional differences for customers. Compared with the cumbersome and inefficient process of making adjustments after the traditional mold manufacturing is completed, this method has significant advantages. If customers detect millimeter-level dimensional deviations between the lid and the bottle during the compatibility verification process, such as a slight looseness in the fit between the outer diameter of the lid and the opening of the bottle, or a slight error in the pitch of the internal thread resulting in poor opening and closing feel, they only need to feedback the details to us. We will immediately coordinate with the 3D printing partner to accurately correct the dimensional parameters at the digital model level, and the new samples can be delivered to the customers in a short time. Through multiple rounds of comparison evaluation and optimization adjustments, the dimensions will be precisely calibrated until they fully meet the customers' expected packaging visual effects and actual use experience.

IV. Making the Lid Shape More Attractive

From the perspective of aesthetic design optimization, 3D printing technology is a crucial tool in every iteration of shape improvement. Currently, the perfume market shows a strong trend of personalization, and the lid shapes increasingly pursue complexity, diversity, and novelty. With the 3D printing samples we assist in obtaining, customers can examine the smoothness of the lines and the rationality of the arcs from all directions and angles. By comprehensively considering the current fashion trends, feedback from the target customer group, and precise suggestions from the professional design team, customers can continuously optimize their creative ideas and gradually carve out an exquisitely recognizable lid appearance that highly matches the perfume brand image.

V. Checking the Mechanical Properties

Although most of the prototypes generated by 3D printing use alternative materials such as plastics, it cannot be ignored that they have extremely high reference value for predicting the mechanical properties of die-casted zinc alloy finished products. We use professional simulation means to replicate various daily use scenarios, perform high-frequency opening and closing operations on the printed lids, and simultaneously simulate slight collision conditions to closely observe the flexibility and durability performance of movable parts such as clasps and hinges. Taking a past design case as an example, during the testing process, it was found that the clasp of the lid showed slight deformation signs after several opening and closing operations. With our sharp professional insight, we quickly identified the potential structural defects and optimized the design structure targeted, laying a solid functional foundation for the subsequent selection of die-casted zinc alloy materials to ensure that the final finished product has stable and reliable mechanical properties and meets actual use requirements.

Ⅵ. Testing the Sealing Effect in Advance

In the sealing function verification stage, we also maintain a rigorous and professional attitude. By simulating different temperature and humidity gradient environments, we carry out a strict and meticulous sealing test process on 3D printing samples, and use high-precision detection equipment to carefully identify the tightness of the fit between the lid and the bottle mouth, and check whether there are slight gaps that may lead to the risk of perfume volatilization and leakage. Even though the material characteristics of 3D printing are different from those of zinc alloy, based on the data results obtained from the test, we can still accurately optimize the sealing structure of the lid for customers. For example, according to the test data, we scientifically adjust the thickness of the sealing lip and optimize the contact angle parameters, striving to ensure that the finally die-casted zinc alloy lid provides excellent and long-lasting sealing and preservation effects for the perfume and effectively extends the perfume's shelf life.

Ⅶ. 3D Printing Service Empowering the Whole Die-casting Production Process

The value of our 3D printing sample service is by no means limited to the initial design verification stage. Based on the accurately determined size specifications, optimized shape designs, and preliminarily verified performance of 3D printing samples, a solid and reliable basis is provided for the subsequent die-casting mold design stage. The parting surface of the mold can be planned and laid out more reasonably according to the sample characteristics, and the gate and runner systems can be designed more accurately and efficiently based on fluid mechanics principles and sample structure characteristics, thus effectively avoiding repeated modification procedures in the mold making process, greatly shortening the mold opening cycle, and significantly reducing the mold opening cost. Entering the production implementation stage, the data resources accumulated in the previous 3D printing stage can help the production team become familiar with the product characteristics in advance, optimize and adjust the process parameters accordingly, ensure the smooth and efficient operation of the die-casting production process, significantly improve the first-pass yield rate of products, and finally help customers quickly and with high quality launch customized perfume lids onto the market, stand out in the fierce industry competition, and gain a competitive advantage.

Ⅷ. Conclusion

As senior engineers of a professional die-casting perfume lids manufacturer, we have opened up an efficient and professional path for verifying the feasibility of the design for customized perfume lids by relying on the 3D printing sample service. Through comprehensively facilitating creative incubation, driving precise design optimization, preliminarily exploring product performance, and combining with the strong support provided for the subsequent die-casting production process, we can effectively meet the strong market demand for high-quality and personalized perfume lids, and help customers firmly dominate the perfume packaging customization field and achieve commercial success.
