طراحی و تولید قطعات

در این زمان ریخته گری در زمینه های مختلفی مورد نیاز است و در صنعت، هنر، فناوری و… کاربرد های فراوانی دارد. فرایند ریخته گری یکی از علوم قدیمی جامعه محسوب میشود و قدمتی 7 هزار ساله دارد. حالا با پیشرفت تکنولوژی و ایجاد روش های مختلف ،موجب شده تا بهترین نتیجه ها از فرایند ریخته گری حاصل شود. قبل از فرایند ریخته گری باید قطعه ی مورد نظر توسط طراحان طراحی شود و سپس وارد فرایند تولید قطعات شود.

Stages of Casting process:

Preparation of casting mold

Molding

Preparation of molten material

Pouring the molten material into the prepared mold

Cooling the molten material inside the mold

Removing the pieces from the mold

Grinding and removal of burrs

The most important stage in producing custom-made parts is manufacturing the mold.

Inside the casting molds, a pore is made in the form of the required customized piece. Basically, these molds are larger than the piece to allow the molten material to shrink during the freezing and cooling process. Casting molds are made in different ways and with different materials such as sand, gypsum, paraffin, polystyrene, metal, etc. Casting molds are generally divided into two types of disposable and permanent ones.

Casting in disposable molds:

These molds, as the name implies, disappear after a single casting process. Sand molds are one of the most widely used molds in this category.

Casting in permanent molds:

These molds do not have the property of expansion, they are made of metal and as the name suggests, they are not damaged after casting and removing the product from the mold, and can be reused many times

  • Design and production of custom parts is done in different ways:

    Types of casting molds:

    Casting with consumable molds

    Precision Casting

    Shell casting

    Vacuum casting

    Casting with consumable polystyrene molds

    Casting with gypsum and ceramic molds

    Casting method is determined by experienced technicians according to the required part, material used, required number and many other factors.

  • The required part is scanned.
  • A two-dimensional drawings of the piece is prepared.
  • A three-dimensional mold of the piece is made.
  • Drawings of the casting model is prepared with the help of a special software for a simulation process of the piece.
  • The choice of materials and alloys is done based on the customer’s requirements or with the help of CES software.
  • Performing the casting process.
  • Quality control of the final product
  • If needed, cutting and machining processes are done.
  • Putting in the furnace if heat treatment is required.
  • Final control of the manufactured parts and performing various QC tests.

Dispatching the products to the customers

  • پر خطر بودن کار با مواد مذاب
  • وابستگی کامل به نیروی کار
  • کیفیت نامطلوب در برخی از روش ها
  • ساخت قطعات پیچیده و به حداقل رساندن عملیات های ماشین کاری و جوشکاری
  • امکان ریخته گری قطعات آهنی و غیرآهنی
  • نا محدود بودن فرایند برای قطعات بزرگ و کوچک
