What is platen in injection Moulding machine?
A platen of an injection molding machine includes a plate-shaped center area having corners, each corner formed with a recess. A plurality of sleeves is received in the recesses of the center area and defines bores for accommodation of column-like holding and/or guide elements.
What is 3 plate mold in injection Moulding machine?
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.
What is 2 platen injection molding?
Two-platen structure has shorter clamping unit which saves the factory space more than 30\%. During the injection, the pressurizing cylinder continues to provide compensating pressure, so that the clamping force is accurate, the error value is within ±1\%.
What is a platen on a mold?
The platens heat the mold and should be at least the size of the mold you want to run. The larger the platen, the larger the mold you can run. A platen size of 16″ x 16″, for example, will result in 256 square inches of surface area. A platen size of 32″ x 32″ will result in 1024 square inches of surface area.
What is the difference between two plate and three plate Mould?
To sum up, two plate molds are the most commonly used injection moulds. It consists of one parting plane and mold splits into two halves, whereas three plate injection mold consists of two parting planes and mold splits into three sections.
What are the advantages of a three plate mold versus a two plate mold?
Three plate mold design has more advantages to locate the gate. It can have a gate located at the middle of the plastic part and allows pin-point gates. Compared to two plate mold or a hot-runner mold, three plate mold is cheaper to build and less likely to break down.
What is a mold platen?
The platen is the “table” or tool that holds the mold cavity. Spaced apart, the mold is inserted and clamped securely to the platens. Once the two platens come together and are held under the pressure of tonnage, the plastic is heated, injected under pressure, and then allowed to cool through a molding cooling cycle.
What is platen machine?
Presses that operate plane to plane are called platen presses. A vertical clamping contrivance clamps the bed, which carries the form into which the composed type is locked, and the platen, which carries the sheet of paper while it is being printed.
What is platen size?
