Introduction to process method of double material injection molded parts

Publisher: Administrator    Date:2021-08-02

Nowadays, the styles of consumer products in society are really changing. They need to be beautiful in appearance and exquisite design, and at the same time, they must quickly meet the market demand. Generally speaking, designers use different materials in different parts for different purposes of consumer products to meet different market needs and achieve the goals of extending product life, increasing beauty and practicability. This kind of aesthetic and practical design requirements will undoubtedly lead to more and more complex production technology, and the dual-material injection molding process has emerged in accordance with this trend.

It is understood that dual-material products can be made with a single-color injection molding machine. Basically, one injection molding machine can do the job. However, the subsequent processing procedures are quite complicated and time-consuming, which directly affects the quality of the product, and the total production cost is not economical. I don’t know if there is a more economical way to make it. In addition to the corresponding changes to the injection molding machine, the skill of mold design is the soul of the whole technology. This is a very important core technology that needs to be grasped. The mold is rotated and shifted to achieve the effect of synchronizing different materials of injection molded parts. This is very valuable.

As many people know, mold design can be roughly divided into two categories: The first category has two mold cavities. The rotation mode is used to transfer the semi-formed mold 180 degrees to the other cavity. The advantage is that the first and second The process can be carried out synchronously, which needs to remember the operation; the other type is a single cavity, the semi-finished product rotates 180 degrees together with the mold, which also needs to be remembered. The design is relatively simple, but the production efficiency is correspondingly reduced. This is an undoubted approach.

It is understood that we know that because molds or semi-finished products need to be rotated, the requirements for mold design and injection molding machines are more precise. In addition, due to the high variability of dual (multi) material injection molded parts, to achieve smooth production and meet expectations, all mold design must be considered simultaneously with product design, and the specifications of the popular dual material injection molded parts on the market are not uniform. , Resulting in more considerations in mold design; coupled with less versatility, mold manufacturers must pay more attention. There are not many products that meet the specifications.

At present, it seems that my country is gradually becoming a global production and manufacturing base for consumer products. Especially in recent years, manufacturers of plastic products in southern China have accepted many orders that require dual-material injection molding skills, which makes my country's dual-material injection molding technology in the domestic market. The application is becoming more and more extensive. It can be seen that the dual-material injection molding process is an inevitable general trend. There is always a wave of trends that promote development, and the injection molding industry is constantly changing.
