I’ll provide you with a brief explanation of “What is a plastic injection mold?” Actually, it is a substance that enables the rapid injection of melted plastic waste or raw material into a closed mold to create the desired product in the desired shape and model inside the mold.
A plastic injection mold can come in various models and sizes, and it is primarily used for the production of small and detailed products. The logic is as mentioned earlier, where the desired products and materials are created by injecting plastic into the mold in the desired shape and model after melting. In various fields such as healthcare, lifestyle, clothing, construction, and more, there is a need for these molds and machines in the plastic industry. If the produced product does not meet the desired details, it can be reheated and recycled, and plastic is poured into the plastic injection mold again to create the product. Due to its suitability for mass production, it is a widely used manufacturing method in many industries. With these machines and molds, plastic parts can be produced in various sizes and categories, from the smallest products to automotive and defense industry items. We’ve briefly discussed what a plastic injection mold is, and for more detailed information, please feel free to contact us.
Working Principle of Plastic Injection Mold
Plastik enjeksiyon kalıbı çalışma prensibi yukarıda da kısaca değindiğimiz gibi makine içerisinden istenilen model de ki kalıp yerleştikten sonra içerisine ham maddenin dökülerek koyulan kalıbın şeklini alması sonucunda ürünün ortaya çıkmasına dayanmaktadır.
Plastik enjeksiyonda üretilen ürünler sağlık sektörüne ya da gıda alanında kullanılacaksa geri dönüşümden elde edilen ham maddeler kullanılamaz ama yaşam alanında kullanılacaksa daha önce kullanılıp geri dönüşüme uygun olan malzemeler alınıp öğütüldükten ve sıcak eritme havuzuna atıldıktan sonra tekrar yeni ürünler üretmek için kullanılabilir.
Plastik enjeksiyon makinelerinin üretim kapasitesi ton bazlı olarak ele alınır ve istenilen renkte, istenilen ince detaylara sahip ürünlerin üretilmesine olanak sağlar. Ayrıca enjeksiyon makineleri daha çok ince detaylara sahip ürünlerin üretilmesi için kullanılır. Plastik enjeksiyon kalıbı çalışma prensibi daha çok ince detayların ince ince işlenmesi, kavis ve desenlerin tam olarak istenildiği gibi çıkartılması için kullanılır.

Plastik Enjeksiyon Kalıbı Malzemesi
The working principle of a plastic injection mold, as briefly mentioned above, relies on placing the mold with the desired shape inside the machine and pouring the raw material into it. As a result, the mold takes on the shape of the product, leading to the production of the final product.
If the products produced by plastic injection are to be used in the healthcare or food sector, materials obtained from recycling cannot be used. However, if they are intended for use in living spaces, materials that have been previously used and are suitable for recycling can be collected, ground, and then used in the hot melting pool to produce new products.
How is a Plastic Injection Mold Designed?
When it comes to the question of how a plastic injection mold is designed, the first step is to determine the desired part’s tensile strength. Tensile strengths are divided into an average value or separate values for longitudinal and transverse elongation. These values are entered into the relevant areas in the design program, and the tensile strength is incorporated into the part’s data.
After calculating the tensile strength values for the plastic injection mold, the mold design is completed by taking into account the following main factors: the properties of the plastic to be used, the removal of parting lines and surfaces, enlargement of mold surfaces, modeling of the mold body, selection and placement of ready-made parts, mold selection criteria, mold material selection, mold dimensions, placement of centering bolts and bushings, placement of fixing bolts, screw locations, prediction of screw dimensions, the effect of temperature on the mold, placement of ejectors, and the position of mold carrying rings.
Indeed, the professionalism of the design team is crucial in all these processes. Because even if the job is done according to the rules, the shaping of all plastics can vary internally. Therefore, the question of who should design the plastic injection mold is more important than how to design the plastic injection mold.
How to Make a Plastic Injection Mold?
When it comes to how to make a plastic injection mold, simplifying the process: plastic injection molding is a manufacturing method that involves melting plastic raw material with the help of heat, injecting it into a mold for shaping, and then cooling and ejecting the final product when it has solidified. This process results in the production of a wide range of plastic products, from small components to garden furniture, in various sizes and categories. It is one of the most commonly used manufacturing methods and relies on a machine called a plastic injection machine.The history of plastic injection molding machines dates back to the 1930s.
The process of making a mold begins with gathering essential information related to the use of raw materials, the model, dimensions, runner preference, and production quantity. A mold consists of two parts: the male and female parts, each containing fastening, support, and securing plates. The choice of suitable raw materials for the product is crucial in mold production. After CAD and CAM programming, molds are machined using CNC, lathe, and EDM machines. Precise measurements and adjustments are made for the alignment, guide, ejector pins, and cooling channels. Once the machining process is completed, the molds are carefully assembled and, after taking the necessary protective measures, they are prepared for mounting on the injection machine.
Plastic Injection Mold Parts
Plastic injection mold components can consist of numerous small parts coming together to form the main body, or they can involve the assembly of 2 or 3 parts to create the main structure. In addition to the parts that shape the form, various components are used to create the fine details and overall structure of the plastic injection mold. These components include columns, bushings, springs, ejector pins, runner systems, alignment elements, valves and seals, cooling systems, and mold components. The quality and durability of all these parts play a crucial role in determining the lifespan of the plastic injection mold.
In general, plastic injection mold components can be listed as follows: female mold, male mold, ejector pins, runner bushing, alignment ring, bottom plate, top plate, support, support plates, ejector plates, and more. The arrangement and organization of mold components have a significant impact on the workflow and the quality of the parts. Any issues or errors in these components will directly affect the final product. Therefore, a plastic injection mold requires maximum quality and craftsmanship.
