Moldex3D Significantly Saves TITAN Costs and Time on Mold Revision

 

Customer Profiles

Located in Taipei County, Titan Mold Corporation was founded in April 1989, bringing together a comprehensive range of the latest in mold making machinery and state of the art techniques.

Before Jason Liu’s job as the managing director of his own mold making company – Titan in 1987, he had already accumulated a twelve-year experience in the mold industry. Experience shaped his reliable expertise and knowledge, and his insistence upon quality is an asset of Jason Liu that supports the company to survive in the competitive mold market. Many consumers are probably unaware of the fact that a lot of well-known 3C products appearance are made in Titan.

A decade ago, while CAE analysis software was just sprung in the Taiwanese industry, Titan already started cooperating with the CAE laboratory in National Tsing Hua University, one of Taiwanese top universities, to add molding flow analysis into the production process. Soon Titan became Moldex3D’s loyal user. Jason said, when transferring the mold making line from low-cost consumer goods to expensive 3C products, how to precisely control each condition and slight change during the molding process is definitely a must-know and the key point. Moldex3D injection molding analysis software not only represents fast, accuracy, and high quality, but most importantly, customers’ trust.

The multiple gating system is frequently applied on molding plastics of 3C products. It not only provides better filling and packing paths to improve quality control but also reduces cycle-time and warpage; yet, the flow trend of multiple gating system is not easy to foretell. Nowadays, Moldex3D is utilized to predict and visualize the mold-filling pattern to shorten the mold design life cycle, so that we can find the optimal gating system before mold tooling. It can also help users to find out the possible defects in advance, such as short shot, weld line, air trap and sink mark, and etc. that would significantly save costs and time in mold revision.

Challenge

Short Shot occurred in the front cover of PC case, while welding line in the back cover of printer. Unbalanced pressure also occurred in printer chassis, monitor frame, and printer cover

Solution

Modify the gate design via Moldex3D to prevent short shot, and modify the design of runner systems to avoid welding line. Reach balanced pressure by changing the runner length and diameters

Benefits

Moldex3D helps users find the optimal gating system before mold tooling and the possible defects in advance, which would significantly save costs and time in mold revision

Multiple gating system—its design and application

(1) Front cover of PC case – short shot

This given case shows that short shot occurs in Design 1 when only 3 gates were employed at first. Melt cannot be transferred efficiently throughout the part. After adding one more gates at a specific location and a flow leader shown in Design 2, the incomplete fill vanishes and we have a better balanced flow pattern and effective pressure delivery in packing stage.

(2) Back cover of printer – welding line

Welding line information is vital for esthetic concerns for most 3C products. Under the assistance of CAE mold filling analysis, users can predict the welding line information, including locations and the temperature. Welding line can be avoided by modifying the design of runner systems. In this product, by modifying the gate number and position (Design 2), we can adjust the filling pattern in order to reach our expectation and meet the quality standard.

(3) Printer chassis – unbalanced pressure

For assembly plastics, the degree of precision is crucial. By merely changing the runner length and diameters, the filling pattern of Design 2 would end up having a better balance than that of Design 1. Besides, the runner system of Design 2 provides better packing efficiency, which eliminates serious warpage problems existed in Design 1.

(4) Monitor frame – unbalanced pressure

Gate positions influence the gradient of pressure drop greatly inside the cavity. In Design 1, the pressure around the marked area is higher than that of Design 2. In Design 2, we move the upper gates closer so that the pressure distribution is much balanced than Design 1, and then the required injection pressure is decreased respectively.

 (5)Printer cover – unbalanced pressure

In this case, we can realize that the pressure distribution of Design 2 is more balanced than Design 1; therefore, less problems on warpage.

 Rooted in Taiwan, Titan and CoreTech both take on international perspectives

Titan now has offices and factories both in Taiwan and mainland China, and customers ranging from PHILIPS, Acer, BenQ, CalComp, Quanta, etc. Moldex3D has helped Titan completing hundred of mold cases, including the most popular precise electronics: digital camera, laptop, cellular phone, scanner chassis and multifunction machine. CoreTech and its professional CAE plastics injection molding analysis software – Moldex3D are the best business partner of Jason. He showed a positive attitude when mentioning Moldex3D’s efforts and support to local mold industry. Although a long way have Titan and CoreTech come through, they still keep walking ahead.


Seal Ring

A seal ring is a crucial component used in various mechanical systems to prevent the leakage of fluids or gases. It is designed to fit snugly between two mating surfaces, creating a barrier that restricts the flow of the substance being sealed.
There are different types of seal rings, each with its own characteristics and applications. One type is the single seal. A single seal ring provides a basic level of sealing and is often used in less demanding applications where the pressure and temperature conditions are relatively moderate. It consists of a single ring that forms a seal between the rotating and stationary parts of a system.
Component seals are another type. These are seals that are made up of multiple individual components. Each component plays a specific role in the sealing process. Component seals can offer more flexibility in design and can be customized to fit specific requirements. They are often used in applications where a combination of different sealing functions is needed.
The double seal is another option. As the name suggests, it consists of two seal rings arranged in series. The double seal provides enhanced sealing performance compared to a single seal. It can handle higher pressures and is more reliable in preventing leakage. It is commonly used in applications where a higher level of safety and sealing integrity is required.
Double Mechanical Seal is a specific type of double seal that uses mechanical means to maintain the seal. It typically consists of two sets of stationary and rotating seal faces. The double mechanical seal offers excellent sealing performance even under harsh operating conditions. It is often used in critical applications such as in pumps handling corrosive or hazardous fluids.
In conclusion, seal rings are essential for maintaining the integrity of mechanical systems by preventing leakage. The choice of seal ring type, whether it is a single seal, component seals, double seal, or double mechanical seal, depends on the specific requirements of the application, including factors such as pressure, temperature, fluid type, and the level of sealing reliability needed.
