2017-webinar-series-web-en

The continuous surge in demand for lightweight yet high-strength design has prompted large components to undergo composite-for-metal replacement. One of the most common processes for making composite products is a two-step process – draping followed by compression molding of the draped part . With this process, the challenge is how to effectively control the deformed shape of the final part. In this webinar, we will show you how to obtain the effects of draping on fiber orientation through LS-DYNA structural analysis software, and then export the effects into Moldex3D for an integrated analysis. Such an analysis can help engineers evaluate the effects of draping on warpage for the best possible design.

Audix Ensures Connector Size Accuracy and Eliminates Appearance Defects through Moldex3D

pdf-logo View PDF Version

Customer Profile
audix

Audix is a semiconductor/electronic component distributor and expanded to certification and manufacturing. Manufacturing Group within Audix produces back light modules, relays, transformers, precision molds, plastic injection products, and also electroplating and automated machinery. A joint venture with Japanese enterprise located in Wujiang produces large-sized CCFL for TVs and monitors. (Source: www.audix.com/index_en.aspx

Executive Summary

This case features a high voltage connector made from PBT, a thermoplastic crystalline polymer ideal for connector applications. Because of its crystalline nature, serious shrinkage problems may occur. The challenge lies in the fact that the product size accuracy is highly demanded to meet the stringent electronic assembly requirement. Also, visible appearance defects such as air traps or short shots are not allowed. Therefore, how to simultaneously achieve the size accuracy and eliminate appearance defects is the main issue in this case. Audix used Moldex3D to analyze the volume shrinkage distribution and adjusted the thickness in the high volume shrinkage region. Audix also adjusted the gate size to eliminate air traps.  Audix was able to successfully solve the shrinkage problem and eliminate visible appearance defects in time to enable an effective workflow forproduct mass production.

Challenges

  • Improve size accuracy
  • Eliminate visible appearance defects

Solutions

Audix used Moldex3D to evaluate the part thickness  and gate design and was able to achieve the optimal product optimization in the early product development stage.

Benefits

  • Improved size accuracy up to 77%
  • Reduced mold trial cost and development time

Case Study

The purpose of this project is to solve the shrinkage problem around the holes on a high-voltage connector in order to meet the accuracy requirement (as shown in Fig. 1). The unexpected high shrinkage around the holes exceeded the pre-set tolerance. In the meantime, air traps would occur if Audix tried to improve the product shrinkage by slimming down the part thickness. Thus, how to achieve the size accuracy and eliminate the visible appearance defects  simultaneously would be the primary objective of this project.

Fig. 1 Shrinkage problem around the holes

After finding the high volume shrinkage region, Audix proposed a new gate design by increasing the gate number from a single gate to a doubled-gate design, one gate on each side (Fig. 2). The doubled-gate design reduced the maximum volume shrinkage from 17% to 14% according to Moldex3D’s simulation results.

Fig. 2 The original design (left) has only one gate. The gate number in the revised design (right) is increased to 2 gates.

Apart from the gate design, the part thickness was modified as well. Audix proposed two different thickness reduction designs. In Design 1, the part thickness at both core and cavity sides are reduced separately in order to meet the geometry aesthetic requirement. Fig. 3 highlights the reduced material locations and the volume shrinkage result. However, the volume shrinkage was not improved as much as expected in Design 1.

audix-ensures-connector-size-accuracy-and-eliminates-appearance-defects-through-moldex3d-4
Fig. 3 Design 1: Reduce materials at the core side and cavity side

In Design 2, the part thickness is further reduced by modifying the slider based on Design 1 (Fig. 4). The simulation results showed that Design 2 can effectively decrease the volumetric shrinkage values at the specific regions. Besides, the volume shrinkage distribution became more uniform after the modification. However, this modification would cause the occurrence of air traps at the side wall (Fig. 5). Hence, Audix enlarged the gate size from 1 mm to 1.5 mm in an attempt to move the air trap location from the side wall to the parting surface.

Fig. 4 Design 2: Reduce materials from sides

Fig. 5 Air trap problem in Design 2

According to the simulation, Audix measured the length of the 4 holes at the top and the bottom of the part to evaluate the size accuracy after shrinkage. The simulation results showed that the length at bottom 1 and bottom 4 after shrinkage exceed the requirement in the original design. In Design 2, the accuracy successfully improved up to 77%, qualifying the part for production.

Audix had conducted a short shot test to verify Moldex3D’s reliability. As shown in Fig. 6, the melt front simulation accurately displays the flow behavior during injection. Furthermore, when Audix compared the actual mold trial with the simulation results of Design 2, they found that the air trap location is coincident with the simulation result as shown in Fig. 7.

Results

With Moldex3D simulation, Audix could understand the flow behavior inside the mold and find potential problems before an actual molding. The accurate prediction helps Audix reduce the cost of mold trials and development time as well as improve the product quality.

New Simulation Capabilities for Polyurethane Foaming

$

Date | 2016/12/26

Polyurethane foam is a common thermoset plastic material used in automotive manufacturing.  It is a porous, low-density and high-strength material, and these features make polyurethane foam a popular material that can be widely applied in producing various automotive parts.  The most common applications include automotive seats, interiors and the parts under the hood. Polyurethane also has other advantages such as moldability, light weight, and long lifetime. Compared to some other thermoset materials, polyurethane is relatively easy to convert back into its original monomer. Additionally, due to the thermoset nature of polymer, it can withstand higher temperature without melting.

Although polyurethane has the advantages mentioned above, there are some challenges in processing polyurethane foam. In reality, the location of the foam within the part is not easy to access.  Furthermore, a large amount of wasted polyurethane materials generated at overflow during the foaming process need to be reduced or recycled.

To address the above issue, CAE simulation enables users to understand the dynamic behaviors in the mold filling process and optimize the product designs.  With the goal of providing a more comprehensive coverage of the foam molding analysis, Moldex3D not only has extended the microcellular injection molding (MCIM) analysis from thermoplastic to thermosetting materials, but also is able to simulate the foaming kinetics now. This simulation capability will be officially released in the upcoming version of Moldex3D – R15.  Through polyurethane foaming simulation, users are able to know its dynamic behaviors in both filling and foaming stage when manufacturing the polyurethane foam products.

The following example is a simulation of the polyurethane foam molding process with polyurethane system, as shown in Fig 1. We set the heat mold at temperature 60oC, inlet stream at 30oC. First, the polymer melt will begin filling the cavity because of gravity. When the filling reaches at one-fourth of the cavity, CO2 gas will be released by the polyurethane reaction, and the polymer viscosity will increase due to the gelation reaction.  Meanwhile, the reaction heat of the exothermic reaction will be released to increase the temperature of the cavity.  As a result, more and more CO2 gases are released to the polymer melt under a relatively high temperature condition. Eventually, polyurethane foam will completely fill the cavity.

In summary, with Moldex3D’s new simulation feature of polyurethane foaming, users can fully understand the dynamic behavior of the foamed thermoset material in both filling and foaming stage. More importantly, the in-depth analysis of polyurethane foaming enables users to avoid trial-and-error which subsequently leads to substantial time and production cost reductions.

Earning Total Savings of $11,500 on Mold Work for LED Products with Moldex3D

Customer Profile
LMT

LMT Mercer Group, Inc., the leading manufacturer of vinyl fence, deck, and railing accessories in the US and Canada, operates three manufacturing plants in New Jersey and Ohio. LMT operates more than 30 state-of-the-art injection molding machines equipped with servo-robotics and nitrogen gas-assist capabilities. It has used Moldex3D for their product development process optimization since 2013. (Source: http://lmtproducts.com/

Executive Summary

Two lighting parts, made from the same material, were both produced in the same mold to reduce the costs. However, their sizes were quite different, so unbalanced filling occurred. Through Moldex3D, the other issues, such as sudden spike in clamping tonnage and overworked cooling channels could also be detected. Therefore, optimization on runner/gate and cooling systems were made that resulted in the eliminations of unbalanced filling and sudden tonnage spike, the reductions of both clamping force and cooling time, and the improvements of both cooling efficiency and part flatness. In addition, substantial time and cost savings could be achieved too.

Challenges

  • To complete the filling process at the same time for both parts
  • To ensure the runner/gate configuration and cooling channel sizes and locations that would not cause excessive warpage on the parts

Solutions

Moldex3D provides the analyses for filling, packing, cooling, and warpage in which the effects of any design changes and modifications in runner/gate and cooling systems on the improvements on filling time, cycle time, cooling efficiency, and part flatness can be observed beforehand.

Benefits

  • Succeeded in reducing the clamping tonnage required at the end of packing from 225 ton to 175 ton which reduces costs of the part too due to smaller press size required
  • Succeeded in having both parts to be fully filled at 1.28 s; the initial runner and gate design resulted in full filing times of 1.07 s and 1.28 s for the smaller and larger parts, respectively
  • Obtained optimized cooling channel design which reduced cycle time through reduced maximum cooling time by 11.99% and made the cooling efficiency difference only 13.759% from 25.452%
  • Improved flatness of the smaller part by 2.56% and of the larger part by 6.18%
  • Earned total savings of $11,500 for mold work and sampling charges

Case Study

The objectives are to reduce the cost of parts by both reducing the press size required through optimized runner/gate and reducing the cycle time, to keep part flatness within acceptable quality limits, and to accomplish all these goals before the making of the mold so that the tooling and sampling costs could be reduced.

Moldex3D eDesign was utilized to mesh the model which contains two different cavities in one mold; the smaller part was for LED board holder, whereas the larger one was for light reflector. Moldex3D became a powerful tool to detect and identify unbalanced filling through melt front time, sudden spike in tonnage of the clamping force, maximum cooling time, overworked cooling lines, and the Y-displacement for both parts.

The changes include runner layout and cooling system as illustrated and explained in Fig. 1 and Fig. 2.

Fig 1. The original design has the edge gate for the smaller part and jump gate for the larger part (left), while the revised design keeps the jump gate for the larger part but uses the extended jump gate for the smaller part (right).

Fig 2. Different from the original design (left), the revised design (right) splits the connected loop cooling channel for the larger part’s top and bottom sides and add a cooling channel for the larger part’s bottom side.

As shown by Moldex3D’s simulation results, the smaller part has been fully filled too early compared to the larger part. The revised design makes the flow path for the smaller part longer from its runner and gate design, so its filling time can catch up with the longer filling time of the larger part (Fig. 3).

Fig. 3 The comparison between the melt front time of the original design at 74% filling (top) and the revised design at 96% filling (bottom) shows that the unbalanced filling for both cavities has been solved.

The next result is the cooling time in which the maximum cooling time can be reduced from 21.009 s to 18.489 s via optimized cooling system design. In other words, the cycle time could be reduced as well. The last result is the Y-displacement which represents the part flatness. The original design results in maximum displacements of 0.1981 mm and 0.6985 mm for smaller and larger parts, respectively. Meanwhile, the revised design can reduce the maximum displacements for both smaller and larger parts to 0.1930 mm and 0.6561 mm, successively.

Fig. 4 The distributions of the Y-displacement for both of the smaller and the larger part show that the original design (left) has larger displacement than the revised one (right).

The design revision was verified by the actual injection molded parts. During initial mold sampling, the process conditions from Moldex3D were given to the process engineer. The process engineer made short-shot parts just before the end of the filling. The injection molded short-shot parts has identical short shot locations to the ones in simulation results as shown in Fig. 5.

Results

This project was a success in which the objectives of both reducing the part cost and improving the quality of the finished products had been accomplished. The design revision was made by modifying the runner/gate design and optimizing the cooling channel layout before the mold steel was cut and shaped. With the ease of use that Moldex3D offers, various designs were tested quickly to find the best results without having to make expensive changes to the tooling after the fact. By improving the mold and part designs with the assistance of Moldex3D, time to market and tool sampling had been streamlined. Thus, substantial time and cost savings could be achieved as well. Besides, the validation comparing the simulation result with actual injection molded parts showed that both filling results were very identical.

Webinar: Visualize Resin Transfer Molding Behavior Using Advanced 3D CAE Technology

Resin transfer molding (RTM), also known as liquid composite molding, is widely used in fabricating composite parts for a wide range of industries, including marine, aerospace and automotive, etc.
In this webinar, we will demonstrate how Moldex3D’s non-isothermal, true 3D simulation technology can provide in-depth manufacturability insights that will allow manufacturing companies to create lighter and more resilient final RTM parts.

Attend this webinar to learn how Moldex3D can help:

  • Accurately predict the resin flowing behavior in the mold, and can be applied to all kinds of fiber mats and complex curved surfaces
  • Gain better control of pressure/flow rate and opening/closing of multiple inlets.
  • Evaluate permeability of fiber reinforcements.
  • Case Studies
