 Principles of injection mold design


To produce a set of high-quality injection molds, not only good mold processing equipment and skilled mold manufacturing workers, but another very important factor is to have a good mold design, especially for complex molds, mold design. Excellent mold design is: under the premise of meeting customer requirements, the processing cost is low, the processing difficulty is small, and the processing time is short.
For this reason, HEYA MOLD not only fully digest the customer's requirements, but also understand the injection molding machine, mold structure, processing technology, and the processing capabilities of the mold factory itself. Therefore, in order to improve the design level of injection molds, the following design principles should be followed:

1. Each injection molded product must first determine its mold opening direction and parting line at the beginning of the design to ensure that the core slider mechanism is minimized and the effect of the parting line on appearance is eliminated.
2. Understand every detail in each mold design, and understand the purpose of each part in the mold.
3. Proper drafting can avoid injury to the top of the product, such as white top, top deformation and top break.
4. In the design process, please refer to previous similar designs, and understand the conditions and lessons to be learned during mold processing and product production.
5. When designing injection molded products, we must consider the contradiction between product appearance, performance and process. Sometimes processes are sacrificed for good appearance or performance. 
6. Learn more about the working process of injection molding machines to deepen the relationship between molds and injection molding machines.
7. The buckle is designed to be shared by multiple buckles at the same time. Therefore, due to the damage of a single buckle, the entire device will be inoperable, thereby prolonging the service life, and then tested and filtered multiple times to increase strength.
8. The factory understands the product processing process and recognizes the characteristics and limitations of each type of processing.
9. The product logo is usually placed on the flat surface of the product and uses a convex shape. The selection of the normal direction and the opening direction of the mold can be set as marks, which can avoid strain. Zhenye Injection Consulting focuses on training and training in injection molding plants.
10. Understand the test results and mold replacement of the mold you designed, and take the course.
11. Insert inserts into injection molded products to improve local strength, hardness, dimensional accuracy and small threaded holes (shafts) to meet specific needs. At the same time, it will increase product costs.
12. When designing, try to use a previously successful mold structure.
13. Setting reasonable fillets can also improve the processing of the mold. For example, the cavity can be machined directly with the tools while avoiding inefficient electrical machining.
14. Learn more about the impact of mold water on products.
15. Pillars cannot be used alone. They should be attached to the outer wall or used with ribs. The purpose is to strengthen the struts and make the rubber flow more smoothly.
16. Investigate some special mold structures and learn about the latest mold technology.

 How to set your injection molding machine parameters? Injection Molding Machine Introduction Technology: Polycarbonate injection molding is an engineering technology that involves transforming plastic into useful and original products. Important process conditions for polycarbonate injection molding are temperature, pressure and corresponding individual time of action that affect plasticizing flow and cooling. Injection moulding machine setting – temperature control 1.  Barrel temperature : Temperature to be controlled during moulding process is barrel temperature, nozzle temperature and mold temperature. First two temperatures primarily affect plasticization and flow of plastic, while latter temperature primarily affects flow and cooling of plastic. Each plastic has a different flow temperature. Same plastic has different flow and decomposition temperatures due to different sources or grades. This is due to difference in average molecular weight and distr...

  What Is Plastic Injection Mold? A plastic injection tooling is a special type of manufacturing tool used for injection moulding. They are usually made of steel. Essentially, a plastic injection mold consists of a large cavity into which plastic is injected. This plastic flows around the core and the cavity, which have been built to create the proper size and shape of your component. Then, the plastic part solidifies on the mold, and is ejected from the mold once it’s hardened and solidified. Then, this process is repeated. A high-quality thermoplastic mold can be used to make millions of plastic components, and is a must-have if you are creating high-quality, high-volume injection-molded components. Plastic Injection Mold Terms If you are new to the world of injection moulding, there are some key terms you may want to know while working with an injection mold supplier. Injection mould This is a steel or aluminum mold that is used to injection mold plastic parts in a high-volume p...

  PLASTIC BUS CHAIR MOULD HEYA MOLD is professional in mould design and custom production of all kinds of chair mould, we have provided the  plastic bus chair mould  for many customers. The public transport plastic chair is a common public facility in our daily life. The public transport plastic chair requires high strength and certain flexibility. In the shaping process of the bus chair, we generally choose ABS plastic material with good mechanical comprehensive performance. In the design process, we first on the bus plastic chair plastic parts for process analysis, to select the appropriate mould and injection moulding machine, and so on. The bus chair for large plastic parts, accordingly need to design large mould and large injection moulding machine. The mould is suitable for single cavity mould structure, using a single point direct gate injection, plastic parts after stripping, the excess part of artificial resection. The steel material of the bus chair mould is usu...
