What Is a Hot Runner? During the plastic injection process a “Hot Runner” ensures that the plastic passing through the runner stays molten by heating the runner. Temperatures along the entire runner, from the barrel outlet of the injection molding machine to the gate at the mold, are in a constant state of flux. By using heating rods and heating rings near the runner, a high-temperature state is maintained and the plastic in the runner is kept molten. Generally, between operation runs, it is not necessary to open the runner to take out the plastic after the machine is shut... Read More
A pair of molds is composed of an upper mold and a lower mold. The male die is a concave die, also known as the upper die. The design of the male mold is very important, and the structural characteristics of the female mold itself change with the structure of the product and the processing method of the mold, which is flexible. What are the Male and Female Molds in the Mold Industry? The mold is divided into the male mold and female mold according to the concave and convex. The mold is generally made of 2-3 parts. The concave... Read More
Installed on a 110-ton MD-S8000 all-electric injection molding machine, the Shot Maker will allow Niigata to change the shot sizes its running at the show from 2.75 to 4.37 to 6.53 oz. Niigata will be demonstrating the Shot Maker by molding a foldable phone holder from a family tool. The 6-cavity tool makes three different sizes of the phone holders, with two cavities forming one holder. The smallest shot size can make one holder, with the medium making four and the largest able to fill all six cavities. The tool was built to show off the both the Shot Maker... Read More
Thermoforming or vacuum forming is a common method of processing plastic materials, and vacuum formed products are ubiquitous in daily life. The process involves heating a plastic sheet until soft and then placing it over a mold. A vacuum then draws the soft sheet into the mold. The sheet is allowed to cool and is then removed from the mold. What is Vacuum Forming? Vacuum forming is a thermoforming process. The processing principle of vacuum forming is to heat and soften the thermoplastic plastic sheet, then stick the sheet on the mold, and vacuum the side of the coating, so... Read More
Many people do not understand what a mold is. A mold (sometimes called a mould) is a block of material with a hollowed-out cavity that has a shape cut into sides of the cavity. Liquid or pliable material is pushed into the cavity where it adopts the shape of the hollowed out section. After the liquid hardens or sets inside the mold, or the pliable material has been pressed into the shape of the mold, the item is removed from the mold. Molds are made from a variety of materials, such as metal, clay, or wood, and can be used... Read More
Do you know how the plastic products are made in our daily living? Bottle caps, bowls, auto parts, etc. Many of the plastic products that are common in life are injected by injection molding machines. When it comes to injection molding machines, many people should have no idea in their minds. Injection molding machines can manufacture limited to plastic products. In this article, we sort out the common injection molding machines with the different characteristics of different models? Let's take a look at the following. What is An Injection Molding Machine? Injection molding machine is a special machine for manufacturing... Read More
Plastic products are very common in our daily lives. Cases for computers, mobile phones and electronics, daily household items, storage containers, automobile panels, furniture etc. are nearly all made of plastic. The method most often used to produce these products is a process called plastic injection. This article will address some of the key points that need to be taken into consideration during the plastic injection molding process, and what processes are required for injection molding. What is plastic injection? Plastic injection technology is used to manufacture a broad range of plastic products that we use daily. The principle of... Read More
Custom injection molding is the fabrication of plastic components using customized design specifications. This service is offered by many manufacturers of plastics. The pricing varies, depending on the type of project involved, but generally custom injection molding is more expensive than using standardized components. People can present manufacturers with their specifications and the number of components they need to get a pricing estimate. In injection molding, heated plastics are shot into a mold. As the plastic cools, it conforms to the shape of the mold and sets in place. The molds can be opened to release the components and they... Read More
An Application of Rapid prototyping is Rapid tooling, this an automatic fabrication of machine tools. Tooling is one of the most costly steps in the manufacturing process. Tools are often complex and need to be wear resistant for production. To meet these requirements, molds and dies are traditionally made by CNC machining, EDM or other methods. All traditional methods are expensive and time consuming; making rapid tooling prototyping the desired alternative. Many believe tooling and design cost may be cut by 50% to 70% by using rapid prototyping. RT Prototyping Rapid tooling is divided in two categories; indirect tooling and... Read More
There are many different types of prototype tools available for those hoping to construct their ideal prototypes. These range from the common to the complex, the everyday to the specialized. A person building a garage-type invention, for example, may use prototype tools consisting of a hammer, nails, screw driver, and so on. More complex inventions might require sophisticated technology or large machinery. Above and beyond the mechanical side of things is another possible interpretation of prototype tools. The technological boom has created a new range of software and technology products that also need to be prototyped. Sometimes, the tools used... Read More
