Basic Design Principles for Gas Assisted Injection Mold(2) Dec 20, 2018
Today we will go on to discuss the basic design principles for gas assisted injection mold 11. Accurate cavity size is very important. 12. The symmetrical cooling of various areas of the product is very important. 13. When using gate inlets, the balance of flow is important for uniform of gas penetration. 14. The exact amount of injection is very important, and the Injection volume error should no...
The Toughness of Mold Steel Dec 20, 2018
During the working process, the mold is subjected to impact load. In order to reduce the damage of breakage or chipping during working, the mold steel is required to have certain toughness. There are many factors to influence the toughness of mold steel, like: the chemical composition, grain size, purity, carbide, inclusions of the mold steel, the heat treatment system; also the metallographic str...

Mold Introduction Dec 14, 2018
Mold Definition and Classification Mold is called “Mother of Industry”. It is a processing tool that processes raw materials and gives raw materials a complete configuration and precise size. It is mainly used for efficient and high-volume production of related parts in industrial products. The development of the mold industry has always been valued by the state. According to the National Developm...

Basic Design Principles for Gas Assisted Injection Mold(1) Dec 14, 2018
Today we are going to discuss basic design principles for gas assisted injection mold 1. When designing, first consider which wall thickness needs to be hollowed out, which surface shrinkage needs to be eliminated, and then consider how to connect these parts into the airway. 2. Large structural parts: full thinning, partial thickening for the airway. 3. The airway should be evenly distributed to ...

Why do we have to test the mould? Dec 14, 2018
Improper mould design will result in defects of the finished product. Therefore, before modifying the mould, it is necessary to test and evaluate the mould, to optimize the mould design and parameters, so as to avoid unnecessary errors, and meet the high quality requirements of mass production. The defects of most molded products are caused during the plasticizing and injection stages, but sometim...
DRAFT ANGEL Dec 11, 2018
Draft Angle 1 、Proper decolleting Angle can avoid product scratching.The demolding slope of smooth surface should be more than 0.5 degree, fine grain (sand) surface is greater than 1 degree, rough grain surface is greater than 1.5 degree. 2 、Proper ejection Angle can avoid product jacking, such as stress mark, top deformation, broken. 3、 In order to ensure that the core of the mould is not out of ...

Factors affecting the quality of die polishing Dec 11, 2018
Since mechanical polishing is mainly completed manually, polishing technology is still the main reason affecting the quality of polishing.In addition, it is also related to mold material, surface condition before polishing, heat treatment process and so on. High quality steel is the prerequisite to obtain good polishing quality, if the surface hardness of steel is uneven or there are differences i...

Reverse Engineering in Mould Making Dec 11, 2018
Geometric modeling technology has been widely used in the development of plastic products. However, due to various reasons, the technical data that mould makers get from clients is not the CAD model, but the physical samples consisting of complex free curves and surfaces. If using the traditional method to design and manufacture product, the cycle time is long and the cost is high. It is unable to...

Ten principles of mold design for P/L (2) Dec 11, 2018
Let’s go on from last article about discussing the principles of mold design for P/L. 6. Good to demoulding The mold release mechanism of the general mold is in the movable mold, so the product should be left in the movable mold as much as possible when selecting the parting surface. Therefore, for some places where it is possible to stick to the fixed mold, we often add a fixed mold assiste...
