Two Plate Mold VS Three Plate Mold

It has an additional mold plate between top clamp plate and cavity plate, called runner plate, which allows the runner scrap and plastic molded parts released separately. Another thing is that the three plate mold requires three times opening. The first opening is to break the gate and pull sprue, so the feeding runner can easily take by arm robot or manually by hand. The stripper plate will move after puller bolts pulled by cavity plate. The second time is called runner opening, which is to release the molded parts. This opening will make space between the stripper plate and the cavity plate.

Selection of type of mold is an essential task in the product development process. Choosing the wrong type of mold can cost thousands of dollars. Although there are plenty of injection mold types available, in this article we will discuss Two plate mold vs Three plate mold. Injection molding is a widely used manufacturing method to manufacture simple to complex plastic parts at a very fast rate. The key component of an injection molding process is an Injection mold, which creates the space for liquid plastics to flow and gets the shape of a core and cavity.

Selection of injection mold type depends on component design, budget and production volumes. During new product development, manufacturers always ask. What type of mold is required? Accordingly manufacturers provide tool estimates. Manufacturers can also suggest ways to reduce mould price. In this article we will discuss two — plate and three — plate mold , their construction, advantages and disadvantages.

Difference Between two plate mold and three plate mold

A three-plate mold is used when part of the runner system is on a different plane to the injection location. The runner system for a three-plate mold sits on a second parting plane parallel to the main parting plane. This second parting plane enables the runners and sprue to be ejected when the mold is opened. In the following diagram of a three-plate mold, the runners will be ejected separately to the cavities. The runner system can be placed on a different plane from the injection location in the following situations:. The mold contains multiple or family cavities.

Two plate mold and Three plate mold

Two plate mold 2. Two Plate Mold A two plate mold is the simplest type of mold. It is called a two plate mold because there is one parting plane, and the mold splits into two halves. The runner system must be located on this parting plane; thus the part can only be gated on its perimeter.

Three-plate mold

Selection of type of mold is an essential task in the product development process. Choosing a wrong type of mold can cost of thousands of dollar. Although there are plenty of injection mold types available, but in this article we will discuss about Two plate mold vs Three plate mold. Injection molding is a widely used manufacturing method to manufacture simple to complex plastic part at a very fast rate. The key component of an injection molding process is an Injection mold, which create the space for liquid plastics to flow and gets the shape of core and cavity. A typical injection mold is made using steel or aluminum. Choosing a mold type and designing a mold needs a high level of experience and different considerations.

Show all documents In 3- plate mould the feeding system can be decided using different approach such as centre gate, off-centre gate and multiple gate systems. The size and location of gate, runner and sprue play importance role for producing good quality plastic product. If wrong method used when choose the feeding system size and location, it will affect the product quality such as welding line, air trap and etc.

Two plate mold and Three plate mold. Two plate mold Two plate mold is the easiest injection mold structure and has many advantages. It's consist with A side and B side 2 main parts, when it is load in ejection machine to do molding, A side is fixed and held still, B side is movable. See below figure to get the details of the 2 plate mold. Some of the term explanation: Location ring : location the filling hole between injection nozzle and sprue, usually made of S55C Return pin : ensure the ejector pin pull back before the mold close, it protects the injection mold from damage, it's usually made of SKD Ejector guide pin : during ejection, EGP works as guiding to ensure the ejection is correct.
