Every industry has its own problems, as is the production of plastic mold. Many routine and unconventional problems may be encountered during the production process of plastic molds. These problems may lead to production delays and losses. Therefore, this article will introduce some common problems and solutions in plastic mold production in detail.
1. Steel problem
Steel is an important raw material for making molds. The quality and performance of steel directly affect the service life and product quality of the mold. In plastic mold production, common steel problems include short service life, improper heat treatment, and uneven cooling. These problems will cause the shape of the mold to be inaccurate, the sample deviations are large, and even the mold is completely invalid.
Solution: When selecting steel, you should choose materials with good wear resistance and corrosion resistance. Regularly perform heat treatment and surface treatment of steel to ensure good performance of steel. In addition, during the entire production process, the cooling should be uniform to ensure that the performance of the steel is excellent.
2. Design issues
Mold design is an important step in making molds. The quality of mold design directly affects the service life of plastic molds and the quality of the product. During the design process, common problems include unreasonable design, and process considerations. These problems can cause the finished product to fail to achieve the expected results, or cause the mold to fail.
Solution: Before the production of molds, you should consider the design of the mold carefully, especially in the design of the mold, plastic parts of injection molding molds should pay attention to the production process of the product to ensure that the design is in line with the actual production. At the same time, designers should be familiar with the principles and processes of plastic processing to ensure the rationality of mold design.
3. Process problems
Mold production is a complex process involving multiple processes. In the process of production, plastic injection mold maps may encounter problems such as uneven cooling, improper surface treatment of molds, and high manufacturing costs. These problems will cause the mold's accuracy, short life, and difficult to achieve the expected results.
Solution: During the production process, pay attention to the cooling uniformity of the mold to ensure that the surface of the mold has a certain uniformity and ensure that the accuracy of the mold meets the requirements. At the same time, during the surface treatment of the mold, pay attention to avoid the shortcomings of the surface, bubbles and other defects to ensure the flatness and cleanliness of the surface. In addition, in terms of manufacturing costs, we can consider using mold manufacturing some improvement techniques to reduce manufacturing costs.
4. Material problems
The problem of mold materials will also affect the effect of plastic mold production and production. In mold production, common material problems include changes in volume viscosity and poor molding caused by the expired materials. These problems will lead to the low quality of the product and low production efficiency.
Solution: During the production process, pay attention to the selection of high -quality plastic materials, plastic line injection molds and avoid using expired or low -quality materials. At the same time, we should pay close attention to the changes in materials and hardware to ensure that the materials used when making molds meet the production requirements.
In general, the common problems encountered in plastic mold production are multi -faceted, and corresponding measures need to be taken to solve. Although there are these problems in the manufacturing process, as long as we deal with it correctly and adopt the appropriate method, the service life of plastic molds can be increased and product quality can be improved.
