Zing Chuan was established in 1986. From tooling design and manufacturing, serial injection
part product and component assembly, all of them could be finished according to client’s request.(Source: https://www.zingchuan.com.tw/en/index-2/)
The heat got accumulated in the inner of the USB stick enclosure part, resulting in a large temperature difference between the inner and outer of the part and causing excessive warpage. In order to increase production yield, an effective cooling system is required. Moldex3D helped Zing Chuan design a suitable conformal cooling system before building the real mold so that the production risk and cost can be reduced. Based on the analysis, the new conformal cooling system is able to dissipate the accumulated heat efficiently. As a result, cooling time is successfully shortened, and product deformation has been corrected.
- Large product deformation due to the interior accumulated heat
- Uncertainty of the effect of developing a new conformal cooling system
Utilizing Moldex3D eDesign to analyze the effect of conformal cooling system during injection and successfully reduce product deformation and cooling time to increase product capacity.
- Improved warpage
- Reduced 33% of total cycle time
- Increased to 1.5 times of product capacity
In order to increase production yield rate, Zing Chuan tried to use a conformal cooling system to improve the heat-accumulated problem inside the product. Moldex3D helped design a suitable conformal cooling system and predict the outcome before tooling.
Moldex3D simulation results show heat accumulation issue in their original cooling system (Fig. 1). It will lead to product deformation. In order to understand the conformal cooling system’s effect, they used Moldex3D to analyze its performance, and found that the part could indeed cool faster (Fig. 2).
Fig. 1 In the original conventional cooling system, the core side has an extremely high temperature
Fig. 2 In the new Conformal cooling system, the temperature has been reduced by 49%
In the original conventional cooling system, the temperature at the core side remains 100℃ at the 12th to 15th second. With the application of the conformal cooling system, the temperature can be reduced to 70℃ within 5 seconds. The warpage was also improved (Fig 3).
Fig. 3 Warpage was also improved with the conformal cooling system
As a result, the cooling time of the conformal cooling system (Fig 4) successfully reduced real time molding process from 17~18 seconds to 7 seconds. This cuts down the cycle time to just 1/3 of the original.
