Enhanced Gate Location Advisor to Quickly Optimize Gating Design

November 17, 2024

Moldex3D Gate Location Advisor can increase the feasibility of mold manufacturing. In the injection molding process, the quality of the product is closely related to the mold design. Particularly, the location and number of gates are important parameters in the mold design. Therefore, the influence of gate design on product quality is extremely important. Inadequate gate design may cause defects such as poor appearance, poor quality of weld line, high shear stress and warpage. In addition, this function provides an advanced flow length ratio (Flow length from gate to end/Average wall thickness) tool, assisting users in evaluating their design. At this time, the Moldex3D 2023 further enhances the Gate Location Advisor for a better gate design and can quickly provide preliminary design recommendations to make flow balance distribution more reasonable.

Step 1. Import Geometry

Preparing a Part model in Studio. Under Model tab, click Gate and Gate Location Advisor to launch the tool.

Step 2-1. Gate location advisor operation process

In the Gate Location Advisor, select Gating Mode: Automatic for optimized gate design with user-specified Non-gating side direction or Constrain gating region. As the following example, the user should have the gating surface on the side only, Check the Constrain gating region, and select Gating region. Then, click Select faces and select on the model as shown below.

Note : 

  1. In Manual mode, users can click Add/Move/Remove to assign the gate position manually.
  2. The Non-gating region and Non-gating side direction often refers to the mold core side (movable) where gating should be avoided.
  3. In Studio, there are only 6 orthogonal directions for setting the Non-gating side direction. If there are other directions required, users should set them through the API.

Step 2-2. Set the number of gates

After selecting the gating surface, the user can enter the number of gates and then click Apply. The tool will then calculate the appropriate gate position according to the conditions entered by the user. In addition, click Show L/t band which can help the user check whether the gate position is appropriate or not  and approximation of the melt front through the Flow Length Ratio(L/t). After completing the design, click the green tick in the upper right to complete the gate location design.

Note : 

  1. The maximum number of gates is 10.
  2. If there are existing gates already assigned, Gate Location Advisor will consider them, and then calculate to add additional gates using the number specified to make recommendations.

Step 3. Result 

The user can check whether the gate location and quantity are appropriate using the Gate Location Advisor and the show L/t band. For example, as the first figure below shows, the longest flow-length ratio at the gate location is 259.475. If the material is HDPE, then the number of gates conforms to the typical flow length ratio range. In addition, users can drag the flow length ratio to observe the positions of each gate at different flow length ratios (black lines), to predict the position and strength of the weld line before simulation. This  can help users determine whether the position and number of gates are appropriate. The 2nd figure below is the melt front time simulated by solver after analysis, so through comparison we can see the prediction from show L/t band function is quite reliable.

Note:  If the user wants to adjust the gate position, they can add/move/remove the gate position in manual mode.


Low Bloom And Low Odor Instant Adhesive

Low bloom and low odor Cyanoacrylate Adhesive is a single-component ,no mixing cyanoacrylate adhesive.Fast curing speed,able to achieve bond strength in a short time.Low bloom adhesive effectively reduces the occurrence of whitening through special formula design,maintain product aesthetics.Has a low odor and does not produce pungent odor,less impact on operator health.
Characteristics of low bloom and low odor instant adhesive:
1. Low bloom: The degree of whitening after curing is very low. For some products with high appearance requirements, such as electronic product casings, optical instruments, high-end handicrafts, etc., using this quick-drying glue can keep the appearance of the product clean. And beautiful, the white residue produced by glue curing will not affect the overall visual effect of the product.
It is especially suitable for bonding transparent or light-colored materials, and can effectively avoid obvious white marks at the bonding interface.
2. Low odor: It has a relatively low irritating odor, no pungent taste, and is not harmful to human health.
3. Fast curing speed: It can be cured quickly in a short time, usually preliminary curing can be achieved within a few seconds to tens of seconds, which greatly improves production efficiency, saves time and cost, and can meet the requirements of mass production and rapid assembly, such as In electronic product production lines, parts can be quickly bonded and fixed to improve production efficiency.
4. Wide scope of application: It has good bonding properties to a variety of materials, such as metal, plastic, rubber, wood, leather, etc., and can be used in various manufacturing industries such as electronics, electrical appliances, optics, lighting, and machinery.
5. High bonding strength: can firmly bond parts of different materials together to form a strong bonding force.
