Hello friends,When the eyes are turned to the war of the titans who are fighting for the presidency in the USA, sometimes it is a little difficult to remember that our life's challenges are just as difficult and maybe even more so. Similar to the two candidates, practicing plastic arts requires us to be grammatical in the smallest details when our ability to meet the task we have set for ourselves is at stake. Get some good tips to help you produce successfully using multi-socket molds.
1. Moving from a single mold to a multi-socket moldGenerally, moving from a single cavity injection mold to a mold that contains injection cavities for multiple items reduces manufacturing costs. This is true as long as the right steps are taken in the matter.In molds with multiple sockets, which are considered larger and more complex, difficulty arises in pouring molten plastic, so a change is made in the material inlets and material channels accordingly, which affects the performance and quality of the product. Also, there is a fear of temperature differences in the body of the mold since the plastic is required to move a greater distance to the finish line. This increases the risk of partial filling of the mold or its subsidence as well as deformations in the finished product.Parts that worked perfectly in a single mold may prove to be unsatisfactory after switching to a multi-slot mold, and often various changes must be made to restore the original quality. This is through a slight change in the structure of the pattern or the composition of the material.
2. Open the gate open it wide
Similar to any normal gate such as airport and school gates, the role of the material inlets (gates) in injection is to control the flow of hot plastic into the mold at the beginning of the injection cycle, and to maintain the pressure of the material until the product cools. In the mold of a single socket, it is customary to use direct inlets as well as hot nozzles that deal well with complex geometric shapes and make it possible to chop the "tail" remaining in the product (in direct inlet). These inputs do not normally fit in a multi-socket pattern. Something more flexible is required here, such as entrances from the product side (edge gate) or submarines.
3. What do we do with family templates?
In the case of low production volumes it is generally recommended to go for a family pattern. What does that mean? Put different products into the same mold. A family pattern is a complex pattern, so it should be treated like any other multi-socket pattern with the same emphasis of caution and this in order to maintain a reasonable quality of execution. To achieve good results, it is important that the nature of the parts in a family pattern be similar in terms of wall thickness, weight, size, etc.
4. Flowing with fun
There are materials with high flow that are more suitable than other materials for filling molds. These materials have a better level of viscosity for performing the operation and therefore we will prefer them over others for multi-socket molds and family molds.
Discussion and conclusions
The use of a multi-socket mold is intended to reduce the costs of producing the parts, and this is true for volumes of tens of thousands and even millions of parts. In order to achieve this important goal, careful planning is required. Attempts to take shortcuts in the form of renouncing the prototype stage may turn out to be a mistake and should be abandoned since the transition to a multiple mold often requires minor changes to be made to the mold or the production material, and it is important to make these changes before the mold is manufactured.
