 Mold flow analysis The operation process and precautions for two-color mold analysis only need 10 steps

1. Hard glue for mesh analysis:




Note: Do double-sided grid analysis first, remember the size of the double-sided grid, create a flow channel and then divide it with a double-sided grid, check that there is no problem before performing the overall 3D grid analysis


2. Soft glue for mesh analysis:

The steps are the same as for soft glue:
Note: The grid size should be consistent with the hard glue, and the aspect ratio of the product should also be consistent with the hard glue.

Two-color product analysis can only be performed on 3D grids

3. Merge the two divided drawings of hard glue and soft glue, and design the product and flow channel for 1-shot and 2-shot respectively.Note: After the soft glue is loaded into the hard glue image file, it does not matter if the runners overlap, and it will not affect the analysis. You need to set the runner properties to 1 shot and 2 shots respectively:

4. Switch the analysis mode to the two-color mold analysis style: Thermoplastiss Overmolding

Molding Conditions of Injection Molding Machine (Part 2)

 1. Filling pressure In injection molding conditions, filling pressure refers to the pressure to fill the resin into the mold, also known as primary pressure. The unit is MPa or kgf/cm2. That is the unit of pressure. There are also some injection molding machines that set the maximum injection pressure to 100%, and then adjust the injection molding conditions by changing the percentage. (Example: 35%) If the filling pressure is too low, poor filling (underfill) will occur. If the filling pressure is too high, the parting surface may be momentarily opened by the pressure, and burrs may appear around the molded product. Sometimes poor release occurs. 2. Injection speed Injection speed refers to the speed at which molten plastic fills the mold. The unit is mm/s. When considering injection volume per unit of time, it may be stated as "injection rate", in which case the unit is cm3/s. If the injection speed is too slow, filling defects may occur; if the injection speed is too fast...

How to choose the original positioning parts of injection mold custom processing workpiece?

 1. Injection mold custom processing workpiece to plane positioning According to the number of degrees of freedom restricted by the plane, it can be divided into three types: The main support surface restricts the positioning plane of the three degrees of freedom of the workpiece, and is often used for the positioning surface of the workpiece with relatively high precision. The guide support surface is a positioning plane that limits the two degrees of freedom of the workpiece, and is often made into a narrow and long surface. The thrust support surface is a plane that limits one degree of freedom. In order to ensure accurate positioning, the area of the plane is often made as small as possible. 2. Injection mold custom processing workpiece is positioned with a round hole Long pins limit 4 degrees of freedom; short pins limit 2 degrees of freedom. 3. Injection mold custom processing workpiece outside cylindrical surface positioning The positioning datum is the centerline of the out...

2K tooling on Injection molding

图片
 Injection molding is a process that was developed based on microfabrication techniques such as LIGA, but there are of course many other methods. The LIGA process is to first produce a model required for injection molding, which is commonly known as "mold", and then pour liquid plastic into the mold, and finally separate it to form the final required product. For example, some Automotive parts have too many products. Injection mold processing is to add plastic to the mold first, and then the mold is continuously rotated along two vertical axes and heated. The plastic in the mold is gradually and evenly coated and melted and adhered to the entire cavity of the mold cavity under the action of gravity and heat energy. On the surface, it is formed into the desired shape, and it is made by cooling and setting.
