In our demand for molds, there is a kind of called two-color mold, generally like a car lampshade, you can see, there are white and red connected, that belongs to the two-color mold. Some people will be curious, how can mold products come out on both sides of the red intermediate white? Two-color mold is generally used by injection molding, but two-color mold we need to inject two colors of materials. Today, we will introduce the use of two […]
The level of mold technology ultimately manifests in the mold manufacturing cycle, mold life, mold precision and stiffness, mold manufacturing costs, mold standardization and other aspects. These are also the basis for evaluating the economic and technical indicators of die and mold.
Mold manufacturing cycle
The mold manufacturing cycle reflects the production technology level and organization management level of the mold and mould enterprise. In manufacturing mold, we should try to shorten the mold manufacturing cycle. At present, in order to shorten […]
Just as we thought Guangdong could not get any bigger and better in terms of manufacturing, Injection Moulding Asia has reported that the province is to hold the Chinaplas exhibition in 2017. Not content with being China’s base for manufacturingelectrical appliances, cars and packaging, Guangdong will also look to specialise in the biomedicine, LED and environmental technology sectors with investment worth over 100 Billion RMB flowing into the region.
This huge investment will hopefully attract other sectors to Guangdong so as to […]
In daily life, plastic products are ubiquitous, and the requirements for plastic products are becoming higher and higher, including material, shape and so on.
How do we make plastic products? There is one way for injection molded plastic products, where the most important part includes the design and development, injection mold, injection materials, the following will be for injection mold this aspect of a brief introduction.
First, what is mold? Mold is a model, according to the model to make products, […]
（1）. Meetsthe requirements of working conditions
When the blank is plastic in the mold cavity, the surface of the cavity flows and slides along the surface of the cavity, which causes the friction between the surface of the cavity and the blank, which causes the die to fail because of the wear. So the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting the wear resistance. […]
The durability of the injection mold is greatly related to the material used, so it is necessary to pay attention to the selection of the mold material. Generally speaking, the mold material should have the following properties:
(1) High wear resistance
In order to increase the rigidity and mechanical properties of the plastic parts, the glass fiber and inorganic filler are widely used in the plastic formulation. After adding these additives, they enter the mold cavity with the molten material at […]
In order to make the mold manufacturing reflect the exquisite workpieces, we will heat the mold, not only to improve the precision of the mold, but also to improve the quality and precision of the work. The following are four important links for the mold heating shared by you, and hope to help the development of the workpiece.
Forging process. This is an important part in the manufacturing process of die parts. For the die of high alloy tool steel, […]
The injection molding process is a common manufacturing method of plastic. The main process flow is as follows: molding, injection molding, pressing (preplastic), cooling setting, die opening, ejecting and clamping. In the process of injection molding, there are three stages in the process of injection molding, namely, premolding, injection and cooling. The following is the hook net to introduce the foundation of mold design in injection molding.
I. Injection molding process:
The screw begins to rotate, and then the plastic […]
Many brands were showcased at the recent Shanghai Optical Fair and it is safe to say that injection moulding and 3D printing look to be the manufacturing methods of the future, as opposed to the original production techniques using cellulose acetate, where frame shapes are cut from pieces of acetate and then bonded together to create multiple layers. While such production can still be cheap, especially for mono-colour frames, this is not the case for difficult designs with multiple colours and a technique that could combine […]
First, digital mold technology has become the mainstream direction.
The rapid development of digital mold technology in recent years is an effective way to solve many problems in the development of automotive mold.
The so-called digital mold technology is the application of computer technology or computer-aided technology CAX in the mold design and manufacturing process. Successful experiences of applying computer-aided technology in automotive die and mould enterprises at home and abroad are summarized. Digital automotive mold and mould technology mainly includes the […]
