When molten plastic material leaves the barrel through the nozzle, it is guided toward the mold cavity, its final destination. Its flow path is called runner system, such as the sprue, runners, gates. The runner is in a simple direct route or goes through a series if turns that the flow molten material twists, and restrictions as it approaches the mold cavity. The molten plastic material flows into this cavity, takes the configuration of this chamber in the shape […]
With the use of injection molding presses and high-performance resins, plastic injection molders are able to craft a broad range of quality custom parts. Just as all resins are unique, these sophisticated machines offer varied capabilities and performance options depending on press size and type.
To ensure optimal quality and value, it’s critical to partner with a manufacturer who can provide the right size press for your specific needs.
How Are Plastic Injection Molding Presses Rated?
An experienced plastic injection molder can help you […]
Before CNC machining was invented, all metalworking fabrication processes were completed with NC (Numerical Controlled) machines. The concept of was introduced in 1967 but the first CNC machines were introduced in 1976. Since then the popularity of CNC grew very significant and it was recognized as the industry standard in 1989. Today, we will tell you the brief history of CNC machining.
In 1948, representatives of the US Air Force (USAF) visited the Parsons Corp. headquarters and Parsons was awarded a […]
A successful hot runner mold application project needs many links to guarantee. There are two most important technical factors. One is the control of plastic temperature, the other is the control of plastic flow.
1. Control of plastic temperature
The control of plastic temperature is very important in the application of hot runner mould. Many processing and product quality problems in the production process are directly due to poor temperature control of the hot runner system. For example, the quality of […]
Rapid prototyping is a process that uses computer aided tools and techniques such as 3D printing and stereo lithography to create physical product models for production tooling and analysis. The process can be very helpful to product designers, component suppliers and even manufacturers and comes with a number of advantages, such as saving time, reducing cost, lowering error etc. It helps you build and test ideas for product development so that you know whether your idea can be turned into a good product in […]
In order to simplify the injection molding process and reduce the waste of parts, it is important to eliminate the need for a large auxiliary cold runner. The key is to ensure that the melt remains molten throughout the flow channel system so that it does not solidify until it reaches the cavity wall where the cavity is cooled.
Internal heating hot runner:
The internal heating hot runner system is the first hot runner system to be put into the market. […]
Plastic is the most versatile material that is used in most applications today. The wide range used of this material has made a great impact in most industrial world. One of the processes in creating plastic product today is called plastic injection molding.
Plastic Injection Molding is a process that has been rapidly growing and which has brought in more momentum within a short range of time. The process of plastic molding injection brings about quite a few advantages. The […]
The advantage of cold runner is that it is easy to use and can meet some aesthetic requirements. The cold runner reduces injection into transparent acrylic or polycarbonate parts used for light transmission, avoiding the visible banding effect of injection in some parts.
In addition to the waste of raw materials, the defects of the cold runner include adding steps to the whole automation or manual process. Removing the cold runner from the parts of the mold requires robots or […]
Plastic injection molding originated with chemists in Europe and The United States who were experimenting with plastics. Originally it was done by hand and pressed into a mold using Parkesine but it proved to be too brittle and flammable. John Wesley Hyatt is the official inventor of plastic injection molding and the process has a rich history with brilliant minds.
John Wesley Hyatt was a creative inventor and developed the processing of celluloid plastics. This was an amazing feat for […]
