Plastic mold processing refers to the processing of plastic molding and plastic blank making tools. It consists of upper mold and lower mold. In our mold factory, plastic mold processing is a very important process. Die processing refers to the processing of forming and blank making tools, and also includes shearing die and die cutting die. What is the processing flow of plastic mold?
Generally, the mold consists of upper mold and lower mold. Place the steel plate between the upper and lower molds, and realize the forming of materials under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding waste materials will be removed.
Specific plastic mold processing process:
- Bottom surface processing and processing quantity guarantee;
- Casting blank datum alignment, 2D and 3D profile allowance inspection;
- Rough machining of 2D and 3D profiles, machining of non installation and non working planes (including safety platform surface, buffer mounting surface, pressing plate plane and side datum plane);
- Before semi finishing, the side reference surface shall be correctly located to ensure accuracy;
- Semi finish 2D and 3D profiles, finish all kinds of installation working surfaces (including the installation surface and contact surface of the limit block, the installation surface and back side of the insert, the installation surface of the punch, the installation surface and back side of the waste cutter, the installation surface and contact surface of the spring, all kinds of travel limiting working surfaces, the installation surface and back side of the wedge), semi finish all kinds of guide surfaces and guide holes, leave margin for finishing the process reference holes and height reference surfaces, and record the data;
- Inspect and recheck the machining accuracy;
- Bench worker inlaying process;
- Before finishing, align the datum plane of the process datum hole and check the allowance of the insert;
- Finish machining profile 2D and 3D, side punching profile and hole location, finish machining process datum hole and height datum, finish machining guide surface and guide hole;
- Check and recheck the machining accuracy.
Plastic mold processing is a complex and highly specialized process that involves several steps to produce high-quality plastic parts. The process involves the use of molds, which are custom-made tools used to shape and form plastic materials into specific shapes and sizes. Here are the basic steps involved in plastic mold processing:
Step 1: Design and Engineering
The first step in plastic mold processing is to design and engineer the mold. This involves creating a detailed blueprint of the mold and its components, including the cavities and cores that will be used to shape the plastic material.
Step 2: Mold Making
Once the design is complete, the mold making process begins. This involves creating the mold using various materials such as metal, aluminum, or composite materials. The mold is then machined to the required specifications.
Step 3: Injection Molding
The injection molding process involves melting plastic pellets and injecting the molten plastic into the mold under high pressure. This fills the cavities and cores of the mold, shaping the plastic material into the desired form. The plastic is then allowed to cool and solidify in the mold.
Step 4: Mold Release
After the plastic has cooled and solidified, the mold release process begins. This involves separating the mold from the plastic material, which can be done manually or using specialized tools.
Step 5: Finishing
The finishing process involves removing any excess material, such as flash or sprue, from the molded plastic parts. This may involve trimming, sanding, or polishing the parts to achieve the desired finish.
Step 6: Quality Control
The final step in plastic mold processing is quality control. This involves inspecting the molded parts for any defects, such as cracks, warping, or other imperfections. Any defective parts are removed from the production line, and the remaining parts are packed and shipped to customers.
In conclusion, plastic mold processing is a complex process that involves several steps, from design and engineering to quality control. By following these steps, manufacturers can produce high-quality plastic parts that meet the desired specifications. With the right combination of materials, equipment, and expertise, plastic mold processing can be an efficient and cost-effective way to produce a wide range of plastic products.
