The history of industrial designs goes back to the industrial revolution in Europe, when craftsmen used industrial methods and not machines on a limited scale. becomes Nevertheless, the design of plastic injection mold was done in the traditional way without software and in limited scales. With the advancement of the computer industry, the design industry got a new boom. This stage is known in the industry as software-oriented technologies. With the progress in software, computer-aided design, computer-aided engineering, and computer-aided manufacturing software gradually flourished. In Sepahan Molding Company, the technique of designing products that can be manufactured by plastic injection method is the result of an industrial design. The design stage of plastic injection mold is the most sensitive stage of plastic mold making, because the first idea of customers reaches the image stage.
An injection machine consists of three main parts: 1. Format 2. Clamping 3. Injection phase Clamping includes a part of the device that keeps the mold closed during the injection process and then opens it. Basically, the molds consist of two halves that must be fixed together by this part during injection. Injection: In the injection phase, plastic materials, which are usually in the form of granules, enter a funnel in the upper part of the machine and from there enter a cylinder surrounded by heaters. Granules become molten or resinous after heating. Inside the cylinder, the materials are turned upside down by a spiral. With spiral rotation, the materials are also pushed forward. And when enough material is stored in the front part of the spiral, the injection operation is done by the nozzle. And the molten material is pushed into the mold channel. The speed and amount of pressure depends on the amount of rotation of the spiral and the diameter of the nozzle. In some plastic injection machines, a staple piston is used instead of a spiral. Dwelling: The Dwelling phase includes a pause in the injection process so that both the melt inside the cavities are completely filled and the gases created are removed from the built-in chambers. Cooling: At this stage, the melt is cooled until it becomes solid and can be removed from the mold. Otherwise, there is a high possibility of changing the shape of the product. Mold Opening: In this part, the Clamping section is opened so that the two halves of the molds are also opened and ready to be launched. Ejection: Several rods together with a plate perform the operation of exiting the part from the mold. Runners and channels of the work piece that are unused and waste are separated from the piece and cleaned to prepare for melting again.
The advantage of the plastic injection method The plastic injection method is considered one of the most important and widely used methods of plastic molding and production of plastic products in industrial molding industries. In this method, the raw material, which is one of the types of thermoplastics, is pushed into the cavity of the mold during a special operation and comes out of the mold after cooling. This plastic injection mold method is mostly used in mass production and prototyping processes. Plastic injection molding is considered a relatively new way of producing products. The first plastic injection machine was built in 1930 and gradually became available to industries. 1- High production speed 2- Wide variety of materials used in this method 3- saving manpower 4- The lowest amount of material wastage 5- Reducing operations after injection in product production
The price of making a plastic injection mold Designing and manufacturing plastic injection molds is a systematic and sensitive process for industrial molding companies. The main competition between molding companies reaches its peak when a company can design and produce a plastic injection mold with the highest quality in the shortest possible time and at a reasonable cost. Sepahan Technik Molding, relying on its 15-year experience in the field of plastic injection mold production and using the latest methods in the world, and relying on its knowledge (which is discussed further) in the shortest time and at the lowest price. A plastic injection mold has met the needs of its customers with the highest quality.

In plastic injection, polymer granules are first melted and then injected into a mold under pressure. The liquid plastic inside the mold cools and solidifies. The raw materials for plastic injection are thermoplastic polymers that can be colored and filled with other additives. Almost all the plastic parts that we use on a daily basis are made using plastic injection technology: from car parts and housings for electronic devices to kitchen appliances. The reason for the popularity and widespread use of plastic injection is the very low cost of making each part in high circulations. Plastic injection offers high repeatability along with high design freedom. The main limitations of plastic injection are economic, because although the production using plastic injection in high circulation is very economical, in contrast, a relatively high amount of initial capital is required to start the process. Another limitation of plastic injection is the relatively high time it takes to get from design to part production (at least 4 weeks).
Manufacturing of rubber and silicone parts, the method of making these parts and their use in the industry have always been of interest. Therefore, we are trying to briefly introduce rubber and silicone parts. Molds of rubber, silicone Rubber and silicone molds are another type of molds. which is cheaper and simpler than plastic and diecast molds. In these molds, unlike plastic and casting molds, the melt is poured into the mold and the part is removed from the mold after it cools down. The working method is that the mold is heated first and after the mold reaches the desired temperature (about 120 degrees in rubbers and 150 to 200 degrees in silicone rubbers). Rubber or silicone is placed in the form of strips or pieces or in the injection chamber (for molds that have an injection chamber) under it. After it has been shaped under pressure and the baking time has passed, the mold is opened and the molded rubber or silicone piece is removed. Cooking: The raw materials of rubbers and silicones have low properties that cannot be used for industry. But combining it with additives and cooking it to create a uniform and stable mixture creates countless uses for it. An important issue is the right time to cook these ingredients. which varies according to the type of substance and additives in it. And due to the lack of re-formability after rubber curing, it is necessary to get proper information about this before injection or molding. This time is very important in the process of forming the rubber in the mold or in the process of its injection. And because after cooking, the material does not change its shape. The curing agent should be added at the last stage after adding all the required additives.
