In addition to these machines, other specialized equipment may be needed depending on the design of the mold being created. For example, if the mold includes intricate details or cavities, Laser Beam Machining may be required to create these features. Ultimately, the specific equipment needed for mold manufacturing will vary depending on the individual project. However, there are some common pieces of equipment that are typically used in this process.

 

6. Quality Control

Quality control is essential in mold manufacturing

cannot be overstated. Quality control is essential to ensuring that the molds produced to meet the highest standards and are fit for their intended purpose. There are a number of ways to ensure quality control in the mold manufacturing process, and it is important to implement as many of these as possible to ensure the best possible outcome.

One way to quality control in the mold manufacturing process is to use quality control software. This software can be used to track the progress of the mold manufacturing process and identify any areas where quality control is lacking. This software can also be used to monitor the performance of the molding machines and ensure that they are operating at their optimum level.

Another way to quality control the mold manufacturing process is to use quality control inspectors. These inspectors can be used to check the quality of the finished molds and ensure that they meet the required standards. They can also be used to identify any areas where quality control is lacking and make recommendations for improvements.

It is also important to have a good quality control plan in place before starting the mold manufacturing process. This quality control plan should outline the methods that will be used to quality control throughout the process and should be reviewed and updated as necessary.

quality control is essential to the success of any mold manufacturing operation. By taking steps to ensure quality control throughout the process, you can ensure that the molds produced to meet the highest standards and are fit for their intended purpose.

Quality control workflow of mold manufacturing

Quality control is an important aspect of any manufacturing process, and mold making is no different. In order to ensure that the molds produced are of the highest quality, a well-defined quality control workflow must be followed.

The first step in the quality control process is to inspect the raw materials that will be used to make the mold. These materials must meet certain standards in order to be used in the manufacturing process. Once the raw materials have been approved, the next step is to begin the mold-making process.

During the mold-making process, a number of Quality Control checks must be carried out. These checks are designed to ensure that the mold meets the required specifications. Once the mold has been created, it must undergo a final inspection before it can be released for use.

Quality control is an important aspect of any manufacturing process, and mold making is no different. In order to ensure that the molds produced are of the highest quality, a well-defined quality control workflow must be followed.

7. Fitting & Assembly

Mold Fitting & Assembly for Plastic Injection Molds

The importance of mold assembly fitting

After each mold part is machined, a trial assembly is made to check the dimensional accuracy of the individual parts and their mutual fit. This is called “mold assembly fitting”. The main purposes of mold assembly fitting are as follows:

1) To check whether the size and position tolerances of the machined surfaces of the individual mold parts are appropriate and whether the dimensional accuracy of the mold as a whole meets the requirements.

2) To check whether the various functional requirements of the mold (such as moving, guiding, supporting, etc.) can be met.

3) To determine whether there are problems such as poor fit or interference between the individual parts and whether the assembly is reliable.

4) To provide a basis for selecting the appropriate mold base and standard components.

5) To determine the location of the water channels, oil holes, and other through holes, and to check their size and position tolerances.

6) To check the size and position tolerances of the mounting holes for the mold components.

The main methods of mold assembly fitting are as follows:

1) Manual assembly: This is the most common method, which is suitable for small and medium-sized molds. The main advantage of this method is that it is simple and easy to control, and does not require special equipment. The main disadvantages are low efficiency and poor repeatability.

2) Semi-automatic assembly: This method is suitable for medium and large molds. It uses a jig or fixture to position the mold parts during assembly, which improves assembly precision and efficiency.

3) Automatic assembly: This method is suitable for large and complex molds. It uses an assembly machine (spotting machine) to automatically position and assemble the mold parts, which further improves assembly precision and efficiency.

The main factors that affect the quality of mold assembly fitting are as follows:

1) The size and position tolerances of the machined surfaces of the individual mold parts. If the tolerances are too large, it will be difficult to achieve a good fit between the parts; if the tolerances are too small, it will be difficult to assemble the parts.

2) The geometric accuracy of the mold parts. If the geometry is not accurate enough, it will be difficult to achieve a good fit between the parts.

3) The surface roughness of the mold parts. If the surface roughness is too large, it will be difficult to achieve a good fit between the parts; if the surface roughness is too small, it will increase the frictional resistance between the parts and make assembly more difficult.

4) The degree of deformation of the mold parts during machining. If the deformation is too large, it will be difficult to achieve a good fit between the parts.

5) The cleanliness of the mold parts. If the mold parts are not clean enough, it will be difficult to achieve a good fit between the parts.

In order to achieve a good mold assembly fitting, it is necessary to control the above-mentioned factors. In addition, the following measures can be taken:

1) Select the appropriate mold base and standard components.

2) Use jigs or fixtures to position the mold parts during assembly.

3) Use an assembly machine (spotting machine) to automatically position and assemble the mold parts.

4) Use a coordinate measuring machine (CMM) to measure the size and position of the mold parts.

By taking the above measures, it is possible to achieve a good mold assembly fitting and improve the quality of the mold.

Mold assembly fitting process

The mold assembly is the process of fitting together the various parts of a mold. This process is critical to the manufacturing process, as it ensures that the mold is properly constructed and will function correctly.

There are a few different methods that can be used to assemble a mold, depending on the specific design of the mold and the materials being used. The most common method is to use screws or bolts to hold the mold together, but other methods such as welding or brazing can also be used.

It is important to make sure that all of the parts of the mold fit together correctly before assembly, as any misalignment can cause problems during the manufacturing process. Once the mold is assembled, it is typically checked for leaks and other potential problems.

 

8. Mold trial(Injection molding)

Mold Trial, Plastic Injection Molding

Mold Trial Process

In order to avoid wasting time and trouble during mass production, it is necessary to have the patience to adjust and control the processing conditions and find out the best temperature and pressure conditions, and develop a standard mold trial procedure that can be used to establish daily working methods.

1. Check that the plastic in the barrel is correct and that it is baked according to the regulations (test molds and production are likely to yield different results if different materials are used).

2. Make sure the material tube is cleaned thoroughly to prevent poorly solved plastic or miscellaneous materials from being shot into the mold. Because the poorly solved glue and miscellaneous materials may jam the mold. Check whether the temperature of the material tube and the temperature of the mold are suitable for the material to be processed.

3. Adjust the pressure and injection volume in order to produce products with a satisfactory appearance. However, it is important not to run rough edges, especially when there are still some mold cavities where the product is not fully solidified. Think before adjusting the various control conditions, because a slight change in the mold filling rate may cause a large change in the mold filling.

4. Be patient and wait until the condition of the machine and mold stabilizes, even for medium-sized machines it may take more than 30 minutes. You can use this time to check the possible problems with the products.

5. The advance time of the screw should not be shorter than the solidification time of the plastic at the gate, otherwise, the weight of the product will be reduced, and the performance of the product will be damaged. And when the mold is heated, the screw advance time should also be extended to compact the product.

Mold Trial, Plastic Injection Molding

6. Reasonable adjustment to reduce the total processing cycle.

7. Run the new conditions for at least 30 minutes to stabilize, and then produce at least one dozen consecutive full mold samples with the date and quantity marked on the container and placed separately by the mold cavity in order to test the stability of the operation and to derive reasonable control tolerances (especially valuable for multi-cavity molds).

8. Measure and record the critical dimensions of the successive samples (they should be measured when they have cooled to room temperature).

9. Compare the dimensions of each sample with those of the mold, paying attention to.

(1) whether the dimensions of the product are stable.

(2) whether there is a tendency for some dimensions to increase or decrease, while showing that the machine processing conditions are still changing, such as poor temperature control or oil pressure control.

(3) whether the dimensional changes are within the tolerance range.

 

9. QC before shipment

What steps are included in the final inspection of the injection molds?

The final inspection of the injection mold is a critical step in the manufacturing process. Injection molds must meet strict quality standards before they can be shipped to the customer. The final inspection includes a visual inspection of the mold, as well as a functional test of the mold. The visual inspection checks for any defects in the mold, such as cracks or chips. The functional test ensures that the mold is able to produce parts that meet the customer’s specifications.
