Molding and designing dept.
By developing and the expansion of the production line VSS Company registered the new business segment Jamin Tarh Parsian, (also known as JTP). With perceiving the demand of the whole company and also the other domestic and international requests in terms of designing and molding industrial elements and parts, JTP as a sister company of VSS Co. has its own industrial process strategy and its own independent vision mission and core competencies.
The manufacturing and building processes of the industrial parts are divided into two groups with a metal cutting and without metal cutting. Production of parts by means of molds is one of the oldest non-cutting production methods. In this method, in general, a holes in the form of pieces to be produced is created and then the raw material in different forms, such as injecting the material into the cavity or compressing it into the cavity inside the mold.
The manufacture of molds as a precision instrument requires a lot of information, including various methods of manufacturing industrial components. The mold parts are produced by various traditional and modern machine tools.
The importance of molding press, pitch board and matrix design, and the precision of mold construction. Why the self-generated molds will have made thousands of pieces of work, resulting in an error in making a molds resulting in errors in thousands of pieces.
Therefore, the precision of mold design and work piece shape is considered to be the basis for choosing design and mold design. A number of modern parts and molds cannot be produced by traditional machine tools, and their production is made using numerical control machines or special machines such as Spark and wire cut is possible.
On the other hand, the services of such machines are expensive. In this way, the manufacturer must carefully examine the design and accuracy of the mold, and, in accordance with it, choose the most economical and fastest method for the production of mold components.
To do this, the maps must be thoroughly examined and the leaf design of the parts process prepared. Then, according to the shape, precision and piece types, determine the best path of the machine. A number of mold parts (such as shoes, bushes, guide molds, punching pins, etc.) are standardized by certain companies. For this reason, many mold makers prefer to prepare these components to reduce production time. Or with the dimensions desired by the company’s constructors. Parts such as pins and matrices are made using hard heat treatment methods after construction.
Therefore, the knowledge of these parts type and the amount of hard work required for them is required. Sanding is the only method of machinery that can help to metal cutting even for hard-working parts.
Among the modern machines, Spark and Wire Cut can also be used to metal cutting of hard-worked parts. Therefore, if necessary, parts can be machined after hard work. The machine tools used to make press molds are:
Traditional methods
Lathing and milling are still used as the main mold making processes in the industry. Most of the components are either produced entirely by these processes or as a part of their process used of Lathing and milling technique. The precision of modern lathing and milling machines is hundreds of millimeters.
Round grinding machine and surface grinding machine are among other traditional processes, which are mainly used after Lathing or milling, for subtle cutting or metal cutting and tolerance of various pieces. Grinding as a process with tools and a different structure foe metal cutting, it alone, is a complete expertise in the industry. The use of the traditional grinding process to create tolerances and adaptations and to sharpen the pinnacle and matrix is common.
New methods
Types of numerical control machines, in particular, numerical control milling and lathing machines, spark machines and wire cutting are new machine processes that are currently used to make press molds. Sometimes, the complexity of the mold parts and the high precision they provide will not save the use of modern machine-molding techniques.
Of course, it’s important that the new machine-tools have a variety of advantages such as high precision and speed, and good repeatability. And these reasons have increased their use in molding.
Computer numerical control machines or CNC
Electro Discharge Machining (EDM) machines operate on the basis of rapid electrical discharge between two surfaces in a non-conducting (D-dielectric) high-frequency liquid. These two levels are one electrode and the other is a piece of work that in this operation on the work surface metal cutting or grinding is happened.
The dielectric liquid acts as a cooling liquid, insulator between the tool and the work piece, helping start the ignition and limiting these sparks in a particular direction. Because this method is very practical, it is used for Tool rebuilding, shallow holes and machine tool cavity molds.
An electric discharge machine is known as Spark, which is also commonly used in CNC machines. Wire Cut is also an EDM or electric discharge machine who’s tooling Wire with a specific gender and diameter. Initially, in the piece work making a thin hole and then the wire is passed through it. With the angle of the wire, the cutting operations are performed on the piece. The Wire cut machines have a CNC control system and provide precision micrometer.
It should be noted that in addition to Spark and Wire cut machines, EDM milling machines, including cutting machines an advanced vector is considered to be the working conditions of the electric discharge processes.
The Vulcan Group of Companies, relying on its molding kit under the name of JAMIN TARHE PARSIAN, has made fundamental steps towards instruction fully in-house and without outsourced production. The JAMIN TARHE, based on the most modern instrumentation tools and with the help of the expert force, is the one of the most famous and high profile companies in the molding industry in IRAN.
