【 Youzhu Injection Molding Machine 】 Customer Case | From process breakthrough to stable mass production, analyze the selection logic of Yuyi Technology

In the cosmetics packaging industry, a perfume cover, a brush rod, and a small transparent bottle seem to be just a small product, but when it comes to production, it often means a series of complex process requirements: both the appearance and the size should be controlled; We need to meet customers' requirements for transparency and tactile sensation, while also considering production pace and batch stability.

For Yuyi Technology, this seemingly simple product is precisely an important scenario for testing the capabilities of injection molding equipment. Yuyi Technology, founded in 2019, initially focused on processing business. With the development of its business, it gradually formed a parallel business model of independent research and development and customer customization. At present, the company mainly serves e-commerce customers and targeted customers. Its products cover perfume covers, brush rods, bottle covers and other cosmetics packaging materials, and has the ability to independently design and develop, mold development and product customization. From customer provided samples or concepts, to structural design and mold development, to sample testing and mass production, our products are also aimed at overseas markets such as Brazil and India.

　　01

　　Not just looking at parameters:

　　How to choose injection molding equipment for Yuyi Technology

For Yuyi Technology, the first thing to solve in equipment procurement is whether it can meet production needs, followed by price. In the actual selection process, the enterprise focused on the injection stability, product appearance quality, and after-sales response speed. After entering the product testing stage, the performance of the equipment under some low-speed and high-pressure conditions did not meet expectations.

Some cosmetic packaging products are not suitable for simply pursuing high-speed injection molding. In special structures such as thick bottom and thin wall, the injection speed needs to be reduced, but at the same time, sufficient pressure and screw pushing ability need to be ensured. Whether the equipment can maintain stability in this state directly affects whether the product can be formed smoothly. It is precisely in actual testing that the Optimal Casting Equipment1%速度、 100kUnder the pressure setting of g, the screw can still be accurately pushed forward, which shows Yuyi Technology the stability of the equipment under low-speed and high-pressure conditions.

　　From 86 seconds to 41 seconds:

　　Complex products ultimately rely on the production results to speak for themselves

　　Thick bottomed thin-walled brush rod: cycle optimization from 86 seconds to 41 seconds

A brush rod produced by Yuyi Technology is a typical process validation. The bottom wall thickness of this product reaches 8 millimeters, but the tube body is very thin, with significant differences in thickness and structure. For the injection molding process, ensuring stable filling of the melt while avoiding appearance defects such as bubbles in the product is a test of equipment control ability and process debugging level.

Previously, when similar products were produced by other manufacturers, process debugging took about 86 seconds, and bubble problems were also prone to occur during the process. After using the optimal casting equipment, the stable production cycle is ultimately controlled at about 41 seconds through the coordination of equipment parameters and process conditions.

　　Case 2

　　Transparent small bottle: from material adjustment to stable production in 35 seconds

Transparent products also have strict requirements for injection molding processes. Yuyi Technology is a small bottle made of AS material with an annual output of about 2 million pieces. Customers have high requirements for product transparency. Through material and process optimization, this product can achieve stable production with a cycle time of about 35 seconds. In another product, the transparency of the customer's original sample is not ideal. After adjusting the material scheme, we have switched to usingPETThe precise control of process parameters by injection molding equipment, combined with the use of materials, ultimately achieved a clearer transparency effect.

　　Case Three:Multi material and complex structure

Facing dual material accessories, the problem is different. Due to two reasonsraw materialThere are differences in the shrinkage rate, and the product is prone to deformation after molding. In response to this, Yuyi Technology improves the consistency of product molding through the combination of equipment performance and process parameters. There is also a product that adopts an external and internal structure, with a more complex process. In order to find a suitable production plan, the Yuyi Technology team searched for suppliers in multiple places in Guangdong and finally overcame this technological challenge.

　　Production cannot be stopped:

　　A 6-hour on-site troubleshooting session

Long term operation of equipment, in addition to its own stability, after-sales service is also an important aspect that production enterprises pay attention to. Since Yuyi Technology started using Youzhu equipment in 2019, the overall operation has been stable. When encountering some technical problems in daily life, they can be resolved through telephone communication; When encountering situations that require on-site handling, technicians can also respond promptly.

The customer recalled that what left the deepest impression on him was a production problem at the end of 2021: at that time, the workshop was producing a PVC product, and the machine adjuster was negligent in operation. After stopping the machine, the material pipe was not cleaned in a timely manner, and the material pipe heating was not turned off. PVC material was continuously burned at high temperature overnight in the material pipe, resulting in carbonization. All subsequent products produced had black spots, and repeated cleaning of the material pipe could not remove the carbon deposits.

Coinciding with the peak production season and urgent order delivery, customers contacted our after-sales service as soon as possible. The technical engineer quickly rushed to the site for dismantling and maintenance. In order to solve the problem as soon as possible, the engineer specially purchased steel brushes and polished and cleaned the screw, screw components, and inner wall of the barrel one by one. They worked continuously for 6 hours and successfully resumed equipment production. Looking back after many years, they are still deeply touched.

Since 2019, the cooperation between Youzhu and Yuyi Technology has gradually extended from equipment selection to multiple products and process scenarios. From thick bottomed thin-walled brush rods to transparent small bottles; From material adjustment to dual material molding; From daily technical support to on-site troubleshooting during major promotions, real production practices have formed the most direct foundation for cooperation between both parties.

For injection molding machines, the true performance is not only written on the parameter table, but also reflected in whether each product can be produced stably, whether each equipment can run for a long time, and whether every production challenge can be truly solved. This is also the most valuable common answer to the ongoing cooperation between Youzhu and Yuyi Technology.
