The effects of mould on injection molding
Because the mold can repeatedly produce products with complex structure and shape. It also has the advantages of high production efficiency, uniform shape, and size of parts, high precision of parts and low cost. Therefore, the mold has become an important technical support for the efficient and low-cost production of the manufacturing industry. A country’s mold industry has become an important measure of its manufacturing level. At the same time, mold quality is also a major factor in product quality.
Injection molds are the most important molding equipment for injection molding products
Their quality is directly related to the quality of the products. Moreover, since the mold occupies a large proportion of the production cost of the injection molding processing enterprise. Its service life directly affects the cost of the injection molding product. Therefore, improving the quality of injection molds, maintaining and maintaining them. And extending their service life are important issues for reducing the cost of injection molding. At the same time, the mold structure is also closely related to the cost of injection molding equipment and raw materials.
Injection molds have a huge impact on injection molding production,8 effects of mould on injection molding following aspects
1, Selection of injection molding machine
Because of the limitations of the parameters related to the injection molding machine and the mold. One type of injection molding machine allows a certain range of mold specifications to be installed. That is, when the mold is made, the corresponding minimum machine is already confirmed. This ensures that the injection molding company has a matching injection molding machine. Otherwise, it is possible to increase the model of the injection molding machine, which will inevitably result in the waste of the machine.
2. Requirements of injection molding supporting facilities
The temperature requirements of the mold. You may need a mold warmer, Water connector specifications, Number of waterways, wire connection method.
3. Requirements of injection molding environment
Because of the product material impact, precision requirements may have requirements on injection molding environment temperature and humidity.
4. Product quality
At least 70% of the product quality is influenced by the mold.For high-precision injection molding machines, the impact of the mold is more prominent. For the appearance of the product, the leather surface mainly depends on the skin texture effect of the mold, and the glossy surface and the mirror surface mainly look at the polishing quality of the mold cavity surface. For the non-design surface of the product, the surface quality of the mold can be directly reflected in the roughness of the surface of the product. For the product size, in addition to the product shrinkage rate and the influence of the injection molding process, the most direct influence is the dimensional accuracy of the mold. The higher the dimensional accuracy of the mold, the higher the dimensional accuracy of the product. The defects of many other plastic products, mold factors occupy a large proportion. See below.
5. Molding cycle
In-mold design, the position of sprue and waterway layout will affect the molding cycle of injection production. The short molding cycle directly improves the production efficiency of injection molding, improves the productivity of the injection molding machine, also means the reduction of production costs.
6. Raw materials – production cost (waste)
The design of the mold runner system will affect the weight of the injection molding waste, which is actually an increase in production costs.
7. Degree of production automation
Mold design, need to consider the realization of injection molding production automation, such as ejection smooth, no post-processing, production stability without quality risk. If the mold cannot meet the requirements, the production must be carried out by operators, which is bound to increase labor costs and increase the instability of product quality.
Reasonable mold design, products meet the requirements, do not need to carry out post-treatment, such as repair flash, shear gate, orthopedic, a full inspection
